11"Dulcinea"Terry McDonoughMark Fergus & Hawk OstbyDecember 14, 2015 (2015-12-14)[a]1.19[6]
The series opens with Julie Mao in a spacesuit alone aboard a spaceship. On the dwarf planet Ceres, Detective Miller is assigned to find Mao and return her to her rich parents on Luna. In New York, UN executive Chrisjen Avasarala interrogates a captured operative of the Outer Planets Alliance (OPA), a militant Belter group, about contraband stealth technology. On its way to Ceres, the ice hauler Canterbury receives a distress signal from the freighter Scopuli, and acting Executive Officer Jim Holden is ordered to lead a rescue mission with the ship's engineer Naomi Nagata, the mechanic Amos Burton, the pilot Alex Kamal, and the medic Shed Garvey. They find the ship empty but for a distress transmitter, but as their shuttle heads back to the Canterbury, a stealth ship destroys the ice carrier with nuclear torpedoes.
22"The Big Empty"Terry McDonoughMark Fergus & Hawk OstbyDecember 15, 2015 (2015-12-15)0.854[7]
On Ceres, Miller investigates the theft of water, now severely rationed due to the Canterbury's failure to arrive. In Julie Mao's apartment, he finds clues placing her aboard the Scopuli. On Earth, Avasarala sends the suspected OPA captive to Luna after her superior, Undersecretary Sadavir Errinwright, disapproves of "gravity torture", but the captive commits suicide. In the asteroid belt, the Canterbury's shuttle is damaged by debris from the ice hauler's destruction. Using the last of their air, the survivors build an improvised antenna to place a distress call, which is responded to by the Martian Congressional Republic Navy (MCRN) flagship Donnager. After Nagata identifies the distress transponder aboard the Scopuli as using Martian military technology, Holden broadcasts a message to that effect to the Solar System, as insurance against being killed as inconvenient witnesses.
33"Remember the Cant"Jeff WoolnoughRobin VeithDecember 22, 2015 (2015-12-22)[b]0.676[9]
Holden's broadcast triggers protests on Ceres, with the OPA blaming Mars for the destruction of the Canterbury. In the course of violent riots, Miller's partner Havelock is attacked, almost fatally, and a man with the handle "Nightbandit31", with whom Mao was in contact, is killed. On Earth, Avasarala tests her theory that Mars was behind the attack by leaking to Mars information about the transfer of Martian stealth technology to the OPA. She deduces from the panicked Martian reaction that Mars was not responsible – but that somebody else wants to start a war. Aboard the Martian warship Donnager, the Canterbury's survivors are detained and questioned, with Nagata in particular being suspected of being part of an OPA sleeper cell. Complicating matters further, an unidentified ship flies towards the Donnager, ignoring all requests to divert or identify itself.
44"CQB"Jeff WoolnoughNaren ShankarDecember 29, 2015 (2015-12-29)[b]0.633[10]
On Ceres, Miller identifies the dead "Nightbandit31" as Bizi Betiko, a data broker with an implanted, encrypted memory storage device, only to discover the real Betiko is still alive. In the asteroid belt, the Donnager's pursuers reveal themselves as six ships of the type that had attacked the Canterbury, and open fire on the Donnager. Unexpectedly at a technological disadvantage, the Martian ship takes heavy damage, and Shed Garvey is killed by a railgun shot. As the Donnager is being boarded, the surviving Canterbury crew are evacuated on the Martian captain's orders, narrowly escaping aboard a frigate from Donnager's bay immediately before the Donnager self-destructs to avoid capture. Far from the battle, at Tycho Station, where a massive generation ship, the Nauvoo, is being built at the behest of the Church of Jesus Christ of Latter-day Saints, station manager, and leader of the OPA, Fred Johnson turns the Nauvoo's sensors towards the battle.
55"Back to the Butcher"Rob LiebermanDan NowakJanuary 5, 2016 (2016-01-05)0.631[11]
For lack of options, the Canterbury's survivors accept a proposal by OPA leader Fred Johnson to join him at Tycho Station, and with his help they modify the ship's transponder, renaming their salvaged ship the Rocinante, to hide the fact it's a Martian warship. A flashback shows how Johnson became "The Butcher of Anderson Station" eleven years ago: as a UN Marine colonel, he led an assault on a station occupied by protesting miners, killing all despite their attempts at surrender. On Ceres, Miller finds evidence linking Julie Mao to the OPA, who try to recruit him through their local agent Anderson Dawes. While leaving Julie's apartment with the data chip, Miller is abducted by unknown people.
66"Rock Bottom"Rob LiebermanJason NingJanuary 12, 2016 (2016-01-12)0.713[12]
On Ceres, Miller is interrogated and tortured by Dawes, demanding to know what he has learned about Julie. Miller escapes, with fellow officer Octavia Muss, and discovers revealing information on a hidden data cube, a major secret. Upon revealing his discovery to his boss, she fires Miller and takes all information regarding the case. Avasarala wants a spy on Tycho Station, and resorts to extortion to get her way. Holden and crew arrive at Tycho Station, with Fred Johnson planning to leverage Holden's testimony for legitimacy with the UN. Holden makes an uneasy alliance, sharing everything he knows about the destruction of the Canterbury and the MCRN Donnager. Johnson seems fairly convinced neither Earth nor Mars was behind the attacks. After disguising the Rocinante as a simple gas hauler, they set out for Eros to pick up a potential survivor of the Scopuli.
77"Windmills"Bill JohnsonDaniel Abraham & Ty FranckJanuary 19, 2016 (2016-01-19)0.502[13]
During a visit to Holden's co-op parents' house in Montana, Avasarala learns of Holden's troubled childhood and gains some insight into his recent decisions. On their way to Eros, the crew of the Rocinante realize too late that Kenzo, a spy from Tycho station is on board and has inadvertently gotten the attention of a Martian patrol. Kenzo helps obtain the MCRN codebook from the ship's safe, and with a few code words the patrol backs off, believing the Rocinante to be a Martian black ops ship. Miller departs Ceres for Eros, with a new piece to the mysterious puzzle surrounding Julie Mao.
88"Salvage"Bill JohnsonRobin VeithJanuary 26, 2016 (2016-01-26)0.721[14]
The Rocinante arrives at their true destination, an asteroid at coordinates given by Fred Johnson and discovers the Anubis, the stealth ship that had destroyed the Canterbury. It is empty except for a mysterious, spreading, organic substance that covers the ship's reactor. They scuttle the stealth ship, then head to Eros to find a survivor of the Scopuli code-named Lionel Polanski, who escaped the Anubis on its shuttle. Miller is also tracking down Polanski, identifying her as Julie Mao. Arriving at Eros, Holden and his team are ambushed at the hotel where Polanski is staying by a UN black ops team (signaled by Kenzo, and authorized by Errinwright), but are saved by Miller. After joining up, Holden's team and Miller go to meet Julie Mao only to find her already dead, infected by the same substance from the Anubis.
99"Critical Mass"Terry McDonoughRobin Veith & Dan Nowak and Naren ShankarFebruary 2, 2016 (2016-02-02)0.555[15]
The events leading up to Julie Mao's infection by the unknown bio-hazard on the Anubis and gruesome death in her hotel room on Eros are revealed in a flashback. Fred Johnson broadcasts evidence that the stealth ships were built on Earth. After Miller and the Rocinante crew flee the hotel, Julie's body is found and studied by Dresden, a scientist working for Julie's father Jules-Pierre Mao, who harvests her infected blood. Under the guise of a ship explosion and radiation leak, mercenaries loyal to Julie's father and Dresden place Eros into lockdown and seal the poverty-stricken citizens into radiation shelters after infecting them with Julie's blood. Most of the Rocinante crew head back to the ship, while Miller and Holden go to investigate the shelters. Discovering their true purpose as incubators for the infection, with everyone inside dead or dying, they also receive a lethal dose of radiation.
1010"Leviathan Wakes"Terry McDonoughMark Fergus & Hawk OstbyFebruary 2, 2016 (2016-02-02)0.555[15]
The Rocinante crew, Miller and Holden suffering from radiation sickness, make their separate ways through the increasingly horrific situation on Eros towards the ship. They theorize that the conspirators behind the stealth ships are using the population as food for the "protomolecule" infection. Miller begins to see hallucinations of Julie Mao. Amos kills Miller's friend, Inspector Sematimba, after he holds Nagata at gunpoint when she refuses to launch the Rocinante without Holden. Miller and Holden make it to the ship, which escapes, and are treated for radiation sickness. On Earth, Avasarala's investigation is stopped by Errinwright, who is part of the Mao conspiracy. On Eros, the UN spy Kenzo is left to be consumed by the rapidly advancing Protomolecule infesting the colony.

111"Safe"Breck EisnerMark Fergus & Hawk OstbyFebruary 1, 2017 (2017-02-01)0.700[16]
The season opens with Martian Marine gunnery sergeant Bobbie Draper and her team undergoing combat training on Mars. They are deployed to Phoebe Research Station, which had been reported as being attacked. The United Nations debates blockading MCRN fleet deployments; Avasarala backs the measure but privately believes that she is being prepared by Errinwright as a scapegoat, and hires private security. An MCRN vessel fires on a UNN vessel; the UN elects not to fire back, figuring that the Martian missiles were saber-rattling. The missiles pass the UNN vessel and destroy Phoebe Station. Draper believes that war with Earth is good; her commanding officer, Sutton, believes war must be avoided. Holden and Miller recover from radiation sickness; Miller and Amos have a violent disagreement that is broken up by Naomi. The Rocinante crew finds a protomolecule sample in a cryogenic safe recovered from the Anubis and decide to hide it in a debris field. Naomi and Holden perform repairs to the Rocinante and their personal relationship deepens. Alex cooks lasagna for the crew of the Rocinante, and over dinner tensions are eased.
122"Doors & Corners"Breck EisnerDaniel Abraham & Ty FranckFebruary 1, 2017 (2017-02-01)0.700[16]
Avasarala hires freelance spy Cotyar Ghazi. The Rocinante crew's arrival at Tycho Station is tense, but the situation is defused by explaining what is happening on Eros and where the data is going. Fred Johnson pulls together a strike team from rival Outer Planets Alliance factions, killing one of their leaders in the process. Rocinante is assigned as the mission's muscle in the assault on Thoth Station, engaging the station's defenses and clearing a path for the boarding party. The station is not prepared to defend itself, and falls easily to the team. Capturing the lead scientist on the project, Dresden, and an underling, Cortazar; Dresden is uninterested in who he answers to as long as he can continue his work. Dresden explains the source, dangers, and possibilities of the protomolecule and tries to convince Holden and Johnson to let him continue the project, but Miller shoots him in the head.
133"Static"Jeff WoolnoughRobin VeithFebruary 8, 2017 (2017-02-08)0.587[17]
Earth destroys Mars's moon Deimos in response to the MCRN's nuking of Phoebe. This creates tensions in Bobbie Draper's squad. Holden and his crew return to Tycho Station, angry at Miller for killing Dresden, the lead scientist on the protomolecule project. Fred Johnson offers Miller safe passage off Tycho, but Miller's investigations show that action must be taken against Eros. Johnson and Holden reach the same conclusion when Amos figures out how to get the captured scientist Cortazar to talk. Miller realizes that Eros must be destroyed, and that Fred Johnson has the equipment necessary to do so: the Nauvoo.
144"Godspeed"Jeff WoolnoughDan NowakFebruary 15, 2017 (2017-02-15)0.534[18]
Avasarala gathers information linking the protomolecule to Jules-Pierre Mao, Julie's father. Miller's plan is put into action. After assembling a demolition team and procuring the Rocinante's services for cover, the Nauvoo is evacuated of its people, commandeered, and set on a collision course to knock Eros into the Sun. After flying to Eros, Rocinante drops its cargo of bombs and the demolition team spacewalks to them for precise placement in order to seal the surface of the asteroid. A complication arises when a group of humanitarian doctors is found who will not follow Holden's orders, so he destroys their ship to prevent spreading the protomolecule infection. The debris damages one of Miller's bombs, and he chooses to stay with it on Eros, watching the Nauvoo approach, but no collision takes place. Holden and crew confirm that the Nauvoo did not miss – despite having no human-built propulsion system capable of doing so, Eros maneuvered to avoid the impact.
155"Home"David GrossmanMark Fergus & Hawk OstbyFebruary 22, 2017 (2017-02-22)0.600[19]
Eros is speeding on collision course for Earth. Miller and the crew decide that Miller will bring the bomb into the heart of Eros to destroy it and then escape back to the Rocinante. On Earth, the United Nations decides to fire its planetary defence nuclear missiles at the incoming Eros, but the asteroid evades them by 'going stealth', ceasing to reflect radar. The Rocinante crew use their proximity to the asteroid to provide a target lock to Fred Johnson, who will guide the missiles to Eros. Eros reacts to this by accelerating still faster; to maintain visual contact, the Rocinante accelerates at the limits of human endurance and finally gives up the chase. Miller arrives with the bomb at the heart of Eros and discovers a transformed Julie Mao. While the protomolecule has infected her and Eros, she has in some way infected it back, and can influence Eros's trajectory. With a combination of words and affection, and after removing his protective spacesuit, Miller convinces her to redirect Eros away from Earth toward Venus, where it crashes in a planetary-scale event.
166"Paradigm Shift"David GrossmanNaren ShankarMarch 1, 2017 (2017-03-01)0.625[20]
Flashbacks to 137 years prior show Solomon Epstein, a Martian colonist, envisaging a future where Mars has broken free from Earth's control based on his invention. In the present, Avasarala demands Errinwright bring Mao out of hiding by threatening Mao's family and business empire. On Tycho, Fred Johnson's idea to use the thirty missing nukes as a bargaining chip against Earth and Mars angers Holden. The crew on the Rocinante commiserate over Miller's death and agree to launch the protomolecule sample into the sun, believing it is too dangerous to keep. But Naomi fakes the launch leading the others to believe there is now no sample left. On Ganymede, Bobbie Draper and her marines are sent to patrol the agricultural farms and they see UN marines running towards them, firing, as their comms are jammed. The UNN and MCRN fleets in orbit each assume the jamming is part of an attack by the other side, and a full scale battle breaks out in orbit – destroying several of the giant orbital mirrors in the crossfire, whose crashing wreckage devastates the colony on the surface. The Scirocco comes under fire and Sutton is killed. After the battle, an injured Bobbie awakes to find her entire team massacred, and an inhuman figure standing over her.
177"The Seventh Man"Kenneth FinkGeorgia LeeMarch 8, 2017 (2017-03-08)0.451[21]
After the Ganymede battle, Bobbie is rescued by the MCRN and asked to report the events, which some of her superiors do not believe. On Earth, Avasarala demands a peace summit between Earth and Mars to prevent further escalation of the tension, in which both planets believed the other fired first on Ganymede. Over three thousand people were killed in the Ganymede Incident, and the massive damage to the colony destroyed the agricultural domes that the Belt depends on – leading to a starvation and refugee crisis. On Tycho Station, a recently arrived Anderson Dawes is asked to represent the Belt in negotiations for peace with Earth and Mars, but Dawes convinces the Belters that Earth and Mars will never respect the Belt. Bobbie is ordered to Earth to the peace summit, and to tell Earth that Mars fired first accidentally, despite Bobbie remembering the presence of an alien figure the UN marines were fleeing from. On Tycho, Dawes becomes aware of Cortazar's presence and knowledge. Cortazar is later found to be missing from his cell, leading Alex and Naomi to chase after an escaping ship, only to find Diogo aboard and Dawes and Cortazar gone.
188"Pyre"Kenneth FinkRobin VeithMarch 15, 2017 (2017-03-15)0.460[22]
Aboard a Ganymede refugee ship, Praxidike Meng and others are headed for safety as he privately mourns the loss of his daughter Mei, who was supposedly killed when the mirrors fell from orbit. The ship's crew throws refugees from the inner planets out of the airlock, reflecting the rising tension between the Belters and the Inners. Prax's ship later arrives at Tycho Station, which is inundated with thousands of refugees from Ganymede. Meanwhile, Fred Johnson receives a message from Dawes, who tells him that he's giving back the weapon (Cortazar's protomolecule information) to the Belt. This earns support amongst the Belters on Tycho, who storm the hangar and take Fred and his subordinate Camina Drummer hostage, wanting to launch the missiles back to Earth in order to provoke a fight, but are unsuccessful when the Rocinante crew intervenes. The crew discovers that a protomolecule 'shout' (signal) came from Ganymede at the time of the battle and discover a paediatrician, Dr. Strickland, who used to work for Protogen, was also on Ganymede. Prax reveals that his daughter Mei was a patient of Strickland's and footage shows Strickland leaving the paediatric clinic with Mei one hour before the battle. Prax, with the crew, set off for Ganymede with renewed hope his daughter is still alive.
199"The Weeping Somnambulist"Mikael SalomonHallie LambertMarch 22, 2017 (2017-03-22)0.471[23]
Approaching Jupiter, the crew of the Rocinante realize that their ship is too obvious, so they commandeer the Weeping Somnambulist, unable to convince that crew they mean no harm. The Mars delegation arrives on Earth for peace negotiations, and Bobbie Draper gives testimony that makes it look like Mars started the battle of Ganymede by accident. Alex takes the Rocinante to hide behind a Jovian moon, awaiting a call from the crew for pickup or rescue, and Prax is unimpressed with the crew's planning abilities. Upon arrival, Holden and Amos realize something is wrong on the Somnambulist and, while attempting to intervene, one of the Somnambulist's crew is killed. A research vessel in orbit around Venus, the Arboghast, discovers that the Eros impact zone is teeming with unexplained activity, information that Avasarala matches with Bobbie Draper's additional testimony to realize that the solar system is still in danger.

Despite chastisement from her commanding officers, Bobbie sneaks out of the Martian embassy to see the ocean. She passes through an enclave of street people under some overpasses along the way. Errinwright confesses to Avasarala his role in helping Jules-Pierre Mao with the Eros incident. Avasarala approaches Bobbie with images of the inhuman figure from Ganymede, now believing Mao created it as a weapon which could wind up in Mars' possession. On Ganymede, Amos beats an information dealer for footage of Dr. Strickland taking Mei to the oldest part of Ganymede station. Prax realizes too much damage has been done to Ganymede's ecosystem to ever repair it. Alone on the Rocinante, Alex receives the MCRN alert declaring Ganymede a no-fly zone.
2111"Here There Be Dragons"Rob LiebermanGeorgia LeeApril 5, 2017 (2017-04-05)0.504[25]
With nothing left to lose, Bobbie assaults Captain Martens, forcing him to reveal "Project Caliban", the protomolecule technology developed by Jules-Pierre Mao, a demonstration of which was behind the Ganymede Incident that triggered the battle in orbit above. The technology is up for sale and was pitched to Mars. Bobbie forcibly takes the relevant information from Captain Martens and subsequently claims political asylum at the UN with Avasarala. Jules-Pierre Mao contacts Avasarala, offering to explain everything if she meets with him somewhere outside of UN control, and she accepts, notwithstanding Cotyar's objections. The research team aboard the UNS Arboghast lands a probe on Venus, seeing a massive protomolecule structure before the feed cuts out. Alex uses the Jovian moons as a Gravity slingshot to sneak the Rocinante past the MCRN blockade of Ganymede. Holden and crew explore the old part of the station, coming across guards and scientists having a pizza party. After Prax starts a gun fight, the survivors barricade themselves in the back room. Holden and Prax realize that the weapon is inhuman monsters that are actually Belter children with genetic peculiarities and purposely infected with protomolecule; the fate of Mei is unclear. After Amos tosses a grenade back at them, the enemy is killed by a protomolecule monster; however, a dying scientist says there are plenty more out there. Naomi and Amos split from the party to evacuate people off Ganymede, while Holden, Prax, and Alex go to hunt the protomolecule monster on the moon's surface.
2212"The Monster and the Rocket"Rob LiebermanMark Fergus & Hawk OstbyApril 12, 2017 (2017-04-12)0.515[26]
Errinwright expresses remorse to Avasarala as she departs to Mao's ship with Bobbie and Cotyar. Mao claims he will give both Earth and Mars access to the protomolecule while he sits comfortably in the middle, preventing war. Errinwright meets with Martian Defense Minister Korshunov, poisoning him with a banned toxin for Martians that makes it look as if he died from a heart attack while also ordering the destruction of the Martian black-ops ship MCRN Karakum that was dispatched to collect the protomolecule monster on Ganymede. Errinwright subtly orders Mao to kill Avasarala and tie up loose ends. Holden becomes increasingly aggressive while hunting the protomolecule monster. Naomi and Amos repair the Somnambulist but it carries only enough air for 52 people, while over 300 refugees riot at the door. Naomi, with the help of a Belter who gives up his spot to her, manages to evacuate all the children and some young adults. When the Somnambulist is fired upon for violating the MCRN blockade, Alex convinces Holden to save them, threatening the MCRN ships with the Rocinante's arsenal. The protomolecule monster is shown to have stowed away aboard the Rocinante.
2313"Caliban's War"Thor FreudenthalDaniel Abraham & Ty Franck and Naren ShankarApril 19, 2017 (2017-04-19)0.581[27]
The protomolecule monster is discovered in the cargo bay of the Rocinante. It attacks and throws a magnetic crate at Holden, crushing his leg and pinning him to the wall. It begins tearing panels to get to the ship's reactor core for its radiation. Amos says the only way to get rid of it is to take the extra air on the ship into a pressurized blast to force the monster out into space, which would also kill Holden. Prax sees the monster as a biological creature craving radiation as a nutrient and realizes the nuclear core in the ship's missiles could lure it out. Naomi and Prax expose a core; Prax throws it at the last second, causing the monster to jump after it and be incinerated by the main engine's exhaust. Cotyar is wounded in a shootout with Mao's men but Bobbie manages to sneak away to get her power armor and saves him and Avasarala at the last moment. As the science team aboard the Arboghast begins a descent to the surface of Venus for a closer look at the protomolecule structure, the ship is completely stopped and then disassembled in an increasing spherical pattern, the fate of its crew unknown. Naomi confesses to Holden that she never destroyed their protomolecule sample; with Earth and Mars already fighting over it, the Belt needed it too, so she gave it to Fred Johnson. On Io, Mei is shown to be alive and kept in stasis with several other children by Dr. Strickland.

307"Delta-V"Kenneth FinkNaren ShankarMay 23, 2018 (2018-05-23)0.625[34]
The protomolecule has formed a structure orbiting beyond Uranus, known as "the Ring". The OPA is now recognized as the representative government of the Belt and is jointly led by Anderson Dawes and Fred Johnson. Earth, Mars, and the Belt send fleets to investigate the Ring. Prax and Mei return home to Ganymede. Anna flies to the Ring with the UNN fleet. Bobbie, reinstated into the MMC, is en route with the Martian fleet. Holden and crew have become famous throughout the system for their actions and are escorting the OPA fleet to the ring. Mars is suing the Roci crew over their ship and Monica and her cameraman are allowed onboard to film a documentary in exchange for paying the crew's legal fees. Naomi and Drummer command the OPA flagship Behemoth (formerly Nauvoo). Dawes' representative and former pirate Klaes Ashford arrives to be Drummer's first officer, joined by Diogo, now a member of the OPA Navy. Ashford undermines Drummer by preventing her from publicly spacing a drug dealer. A UNN tech crew is deployed to a support ship in the earth fleet. Crew member Melba Koh places a bomb on the ship, and uses superhuman strength to kill a coworker who discovers it. As a Belter racing ship slingshots through the Ring it instantly decelerates to a near complete stop, killing the pilot before disappearing through the ring. Alone in his quarters on the Rocinante, Holden sees a vision of Miller sitting on his bed.
318"It Reaches Out"Kenneth FinkMark Fergus & Hawk OstbyMay 30, 2018 (2018-05-30)0.609[35]
Melba hides the body and transfers to the Thomas Prince, feeling remorse for the murder and briefly meeting Anna. On the Rocinante Holden keeps scanning himself for brain defects and protomolecule, finding nothing wrong. Miller only shows up when he is alone, speaking gibberish, alarming Amos and Alex that Holden seems to be talking to himself. Holden uses timestamps from Monica's footage to realize Miller first appeared when the racer activated the Ring. The cameraman swaps out a circuit on the Rocinante. Miller is able to say he is an Investigator, he and Holden are both tools for "it" to get to the Ring. Melba destroys the Seung Un and a message plays of Holden claiming responsibility, stating the Ring belongs to the OPA. The Rocinante is unable to communicate outwards. On the Behemoth Ashford demands they fire on Holden to prove the OPA is not with him. Despite Naomi's protests Drummer gives the order and the ship malfunctions but eventually fires. Holden is able to get Amos to give him a minute alone. The protomolecule Miller says that they are moving too fast. Holden is able to convince Alex to slow down and head for the Ring; the deceleration hurting everyone on board. Holden wakes up to find time on the ship slowed to almost a complete stop, the missile just behind them as the ship starts to enter the Ring.
329"Intransigence"David GrossmanHallie LambertJune 6, 2018 (2018-06-06)0.568[36]
The missile has been stopped and redirected by the Ring but the Rocinante is unable to communicate or access any weapons. A Martian ship follows them inside; a probe touches the edge of the Ring and vanishes. Cohen the cameraman admits to sabotaging the ship but says he only wanted information and never met the person who contacted him to do this. Amos sends him and Monica out of the ship to be picked up by the Martians to explain Holden's innocence. Unable to repair the ship without Naomi, Holden believes their only option is to surrender to the Martians. On the Behemoth Ashford's talks with Naomi make her realize her heart is still with the Rocinante. Drummer rallies the Belters to enter the Ring but lets Naomi take a shuttle back to her old crew once inside. Flashbacks reveal Melba is the other daughter of Jules-Pierre Mao who could never get his approval as he preferred Julie. Melba intends to destroy Holden for her father. Earth's civilians are evacuated away from the Ring but Anna is able to stay. Miller has Holden investigate the center of the pocket dimension the Ring connects to. Holden detaches himself from the ship and goes towards a structure in the center.
3310"Dandelion Sky"David GrossmanGeorgia LeeJune 13, 2018 (2018-06-13)0.615[37]
The Thomas Prince enters the Ring. Anna and others on board theorize the Ring is trying to isolate potential threats. Anna's friend Tilly recognizes Melba as Clarissa Mao and confronts her. Clarissa attacks Tilly to avoid being revealed. The Investigator admits he is just a construct in Holden's brain attempting to fulfil the protomolecule's mission of discovering what happened to an ancient civilization. As Holden goes towards the station at the center of the pocket dimension he touches a circuit, revealing Miller's last thoughts to get Holden to comply. Believing Holden to be insane, a Martian team including Bobbie follow him. They fire at Holden but the bullets are stopped in mid-air and a Martian lieutenant is disassembled and absorbed by the station when he throws a grenade. The station forces every ship to slow down further, interrupting Clarissa's attack on Tilly. Holden touches the circuit and is shown visions from the protomolecule's point of view. He is shown previous events in reverse before witnessing events in the distant past, planets exploding and a connection to farther away in space, and finally loses consciousness.
3411"Fallen World"Jennifer PhangDan NowakJune 20, 2018 (2018-06-20)0.670[38]
The mass deceleration caused fatalities and severe wounds among all the ships; without gravity internal wounds cannot drain, meaning many more will die. Naomi returns to the Rocinante treating a wounded Amos and Alex. On the Behemoth, Drummer and Ashford are pinned on opposite sides of a large piece of equipment, working together to try to free themselves and learning about each other. Drummer allows it to roll forward, crushing her further to give the ship a captain in Ashford. Once free, to treat Drummer and the others, Ashford commands the ship's drum to create spin gravity, opening the ship to everyone's wounded. Leaving Tilly for dead, Clarissa realizes with all ships being drawn to the center, she can board the Rocinante. However, Tilly survives just long enough to tell Anna the truth. Clarissa boards the ship and attacks Naomi, seeking Holden, but Anna followed and tasers her from behind. On Bobbie's skiff, Holden wakes up and tells her he saw a vision detailing the end of everything.
3512"Congregation"Jennifer PhangDaniel Abraham & Ty FranckJune 27, 2018 (2018-06-27)0.730[39]
Everyone boards the Behemoth with all weapons seized by the OPA. Holden is believed to be insane and Clarissa wears an injection system to impair her abilities. She is locked across from Holden without him knowing who she is. Anna tells her all she can hope for now is forgiveness. Holden tells Ashford the beings that created the Rings and protomolecule were somehow killed and used Rings to destroy planetary systems, attempting to save themselves. Drummer builds herself mechanical legs with help from Naomi, whom she later reunites with Holden. Clarissa can hear Holden's torment as he tries to get Miller to tell him what to do next. Amos takes a liking to Anna. A tech from Earth has the idea to send a damaged skiff with a nuclear missile to try and weaken the field blocking immobilizing ships and blocking the laser communication to the outside world. In response, the station begins charging energy. Ashford realizes the station intends to destroy the entire solar system and convinces the leaders of Earth and Mars to destroy the Ring with the laser, saving humanity at the cost of marooning everyone inside the Ring.
3613"Abaddon's Gate"Simon Cellan JonesDaniel Abraham & Ty Franck and Naren ShankarJune 27, 2018 (2018-06-27)0.606[39]
Holden finally has a conversation with Miller and tells everyone else they must power down all the ships. The station is trying to decide if humans are a threat and Ashford's laser will cause it to destroy the solar system. As Holden, Naomi and Drummer storm the Behemoth's reactor room, Amos and Alex recruit Anna and Monica to broadcast to the other ships asking them to power down. Clarissa is freed to work on the electrical system for the laser. Anna's message causes panic and Bobbie's squad is sent to stop the broadcast. The Marines turn on Bobbie, who has no choice but to defend herself and Alex. She is wounded during the fight. Diogo attacks the reactor room in Martian power armor, Drummer stays behind to deal with him but Naomi crushes him with an elevator to save Drummer. Anna's message convinces the other ships to power down. Ashford orders Naomi and Holden killed, but Clarissa saves them and takes a bullet to shut down the Behemoth. The station releases all the ships as it reactivates the remaining Rings to 1300 habitable planetary systems. Ashford, Clarissa and Bobbie all survive. Bobbie joins Rocinante's crew as a gunner. Holden tells The Investigator it wanted the rings open all along, to find out what killed its creators, and has just given humanity something to explore as part of its plan. As the Rocinante passes through the Ring barrier while Holden watches, some ghostly object seems to speed towards Holden.

371"New Terra"Breck EisnerMark Fergus & Hawk OstbyDecember 12, 2019 (2019-12-12)
As portals to numerous different solar systems with habitable planets are revealed through the Ring, UN Secretary General Avasarala orders the UNN to blockade a growing fleet of settler ships, as she, wary of another potential Eros Incident, maintains a cautious approach to the new worlds. Desperate to pass through the Ring Space, a convoy of Belter refugees from Ganymede attempts to run the blockade; most are destroyed or crippled, but the Barbapiccola makes it through, eventually landing on a Lithium-rich alien planet they christen “Ilus”. Avasarala taps James Holden, sending him as her special envoy to contact the Belter settlers on Ilus and identify any risk of Protomolecule exposure or other potentially cataclysmic event resulting from alien lifeforms. While orbiting Earth, Amos is contacted from prison by Clarissa Mao, and she thanks him for his kindness towards her during the trip back from Ring space. Holden, who continues to see/interact with Miller’s apparition, accepts the job, and leaves for Ilus. He is joined by the Rocinante crew, including Naomi, who wants to be able to land with her crew on Ilus; she begins a brutal drug regimen to alter her body composition so she can tolerate a planet with gravitational pull similar to Earth. While in the vicinity of Mars, Alex briefly reaches out to a depressed Bobbie Draper, but communication difficulties cut their conversation short. Similarly, Naomi reaches out to Drummer (who commands the OPA Behemoth as the only human warship in the Ring Space) as they pass through on the way to Ilus; Drummer states the Belters were foolish to attempt to live on the alien planet. Ahead of them, an Earth ship Edward Israel is ferrying an expedition by Royal Charter Energy (RCE), a corporation which has been granted an exploration/exploitation charter by Earth and Mars (but without any involvement by the OPA). As a heavy shuttle descends to “New Terra”, as it is known by Earth and Mars, it is destroyed near the landing pad, resulting in many casualties (including the expedition’s leader and also the ship’s medical doctor) and the loss of a great deal of supplies. Security Chief Murtry (who becomes the de facto leader of the RCE expedition) and some of the other surviving shuttle passengers (including exo-biologist Dr. Elvi Okoye) choose to remain on the planet, but almost immediately come into conflict with the Belters settlers (who are also suspected of bringing down the shuttle). The Rocinante crew arrives to find an escalating situation that results in an armed standoff, which is interrupted when a swarm of alien “bugs” attacks the compound.
382"Jetsam"Breck EisnerLaura MarksDecember 12, 2019 (2019-12-12)
Bobbie Draper struggles with the stagnating Martian job market as a veteran, working a menial job dismantling decommissioned warships; she is singled out as a suspect in a violent crime due to her record of military insubordination, and she experiences other harassment as well. When Avasarala visits Mars on a diplomatic mission, she invites Bobbie to a diplomatic dinner; Bobbie becomes offended when she perceives she was used as a prop to show Avasarala's solidarity with Mars, and refuses Avasarala's offer of work. Meanwhile, while living with her brother and his family, Bobbie becomes suspicious of a late-night outing by her nephew David; following him, she finds him “cooking” illicit “focus drugs” for a criminal gang; she ends David’s involvement by beating the crew who shows up to collect the drugs (and accidentally but without regret destroys the almost-completed batch). On Ilus, Holden and the Rocinante crew navigate the simmering tensions between the Earther and Belter settlers, while identifying the “bugs” as Protomolecule-based technology. Alex discovers that the drugs Naomi has been taking have not been as successful as she really needs to properly handle the gravity on Ilus, but she coerces Alex into keeping the information from Holden. Amos starts a sexual affair with Chandra Wei, Murtry's second-in-command, and accompanies Murtry to the shuttle crash site, where Amos identifies the downing as a deliberate bombing. Murtry further antagonizes the Belter settlers, and after another standoff he kills a belligerent Belter named Coop, who made verbal threats. Holden explores a massive alien structure near the settlement; late one night, Miller guides Holden (accompanied by Alex) to remove a root growing through a panel. This seems to activate the structure, triggering a series of lightning strikes.
393"Subduction"David PetrarcaDan NowakDecember 12, 2019 (2019-12-12)
On Earth, UN Home Secretary Nancy Gao resigns from Avasarala’s cabinet and runs for Secretary-General against Avasarala, on a pro-expansion platform, an approach diametrically opposite to Avasarala's conservative caution. Avasarala's aides uncover a nepotistic scheme that put Gao ahead in her career, which Avasarala orders leaked as political ammunition against Gao. On Mars, Bobbie’s nephew David is kidnapped by the criminal gang and forced to work off the debt incurred by her destruction of the drugs when she removed him from their operation; the gang offers to release David if Bobbie helps them steal military equipment from the shipyard where she works. Attempting to report the kidnapping, she is shocked to discover the ringleader of the gang is a Martian police detective, Esai Martin, who quashes her effort, pointing out he’s a decorated cop with a high conviction rate, while she’s a disgraced former marine no one will believe. Bobbie demands assurance that no weapons will be taken, then capitulates to save David, agreeing to leave a normally secure door open at her workplace so the criminals can steal military tech she’s been stripping from the decommissioned Martian warships. She is able to identify the people who show up to steal the gear as Belters. Esai keeps his word and releases David from his employment, but later extends an offer to bring Bobbie into his operation; she declines. On Ilus, another Earther-Belter standoff is interrupted when lightning activated by the alien structure strikes the settlement. The Belter’s power generation infrastructure is damaged, leaving them in the dark; Murtry isolates the Earther side of the camp and refuses to provide any aid or supplies to the Belters. Using electronic surveillance, Murtry identifies the group of hostile Belters who were responsible for the landing pad bomb, and has them executed in broad daylight. Naomi helps one Belter, Lucia, escape. Accompanied by Alex and RCE biologist Elvi Okoye, Holden finds another alien structure which became active following the lightning event; it is rotating rapidly, chewing up wide swathes of ground, and moving in the direction of the Belter camp. Despite Okoye's protests, Holden orders Alex to destroy the structure with a torpedo from the Rocinante.
404"Retrograde"David PetrarcaMatthew RasmussenDecember 12, 2019 (2019-12-12)
Since the truce between Earth, the Belt and Mars, Ashford has operated as an OPA peacekeeper, tracking down and neutralizing renegades. Meanwhile, Drummer is in command of Behemoth, which controls the Ring Space. They identify Marcos Inaros, an infamous OPA pirate (not unlike Ashford had been some years before the Ring opened), as the pirate responsible for capturing a UNN colony ship, Sojourner, and for spacing the Earthers aboard and stealing the ship and its cargo. With Earth and the UNN demanding the OPA take action against Inaros, Ashford and Drummer (who have resolved their differences and now cooperate with mutual respect) enlist several other OPA factions to capture Marco Inaros. Initially, the factions seem united in putting Inaros to death for violating the truce. Inaros appeals to Belter solidarity and makes the case that while the OPA members think they act in the interest of the truce, they actually only act in the interest of Earth. Ashford, Drummer, and other faction representatives hold a vote and ultimately set Inaros free, accepting his offer to forfeit his gains from the Sojourner and to sit on the sidelines. Privately, Drummer explains to an angry Ashford her decisive vote to free Marcos as a purely political move; if she had voted to kill Inaros over the objections of two major OPA factions, it might have sparked a civil war within the OPA; however, if Inaros breaks his pledge to remain on the sidelines, then no faction would stand against killing him. On Mars, Bobbie attempts to confess to her supervisor her cooperation with the theft of the military tech, but is disillusioned when he instead enthusiastically seeks to get involved in the scheme. Bobbie quits the job and is later arrested for her participation in the crime. She reaches out to Esai; the charges are dropped as she agrees to join his crew on a “full time” basis. On Ilus, violence breaks out as Naomi flees with the Belter doctor Lucia Mazur, who was complicit with the landing pad bombing; Amos creates a diversion by attacking Murtry's forces and is captured, his life spared by Wei’s intervention. Naomi, her body becoming dangerously weak from the effects of gravity and failure of the drugs, attempts to get Lucía to the parked Rocinante; Murtry pursues them but is forced to retreat when Holden and Alex intervene, firing at the security team with the ship's PDCs. Alex, Naomi and Lucia leave the surface and go into orbit on the Rocinante, while Holden stays behind, punching Murtry and taking command of the settlement as Avasarala's envoy.
415"Oppressor"Jeff WoolnoughDaniel Abraham & Ty FranckDecember 12, 2019 (2019-12-12)
On Earth, Avasarala preps for her first public debate against Gao. Initially, Avasarala gains the advantage, playing up her role in neutralizing the Eros Incident, but her attempt to use accusations of nepotism against Gao backfires, and then the debate is cut short by a security threat; Avasarala is rushed out of the building on camera. The threat resulted from an unidentified ship approaching Earth. Initially claiming to be a civilian ship experiencing multiple system failures, it goes silent after altering course towards an Earth asteroid defense platform, and based on drive signature is identified as the Sojourner, the ship Marco Inaros had captured and claimed to have broken up to sell piecemeal. Avasarala promptly has it destroyed. On Ilus, Holden takes command of the settlement but is unable to resolve the escalating tensions between Belters and the RCE crews. Okoye pieces together Holden's connection to the alien technology. Believing the settlement is in danger from reactivating alien tech, Holden attempts to rally the Earthers and Belters to put aside their differences and leave the planet, but neither faction budges, both unwilling to accept the risk of forfeiting their claim. In the orbiting Rocinante, Lucia learns from her husband (who is still in the settlement) that their daughter has disappeared; following an acrimonious conversation with him, and blaming herself for splitting up her family due to her involvement in the landing pad bombing, Lucia attempts suicide. Alex finds and saves Lucia, and Naomi counsels her to deal with her guilt, drawing from her own life experience as a lover and accomplice to Marco Inaros. Later, Alex discovers that an island on the far side of Ilus has exploded in what appears to be a massive fusion reactor failure, generating a gigantic shockwave that begins to speed across the planet’s surface.
426"Displacement"Jeff WoolnoughHallie LambertDecember 12, 2019 (2019-12-12)
Alex and Naomi contact Holden, informing him of the massive explosion on the other side of Ilus, and warning of the impending effects: an earthquake very soon, followed by a dangerous shockwave packing winds in excess of 200 km/h, which itself will be followed some hours later by a catastrophic tsunami that will reach the settlement the next day, destroying the buildings and submerging at least a third of the continent. With this knowledge, the settlers finally agree to evacuate the camp, but the Belters only agree on the condition that Holden call for Avasarala to support their claim; Holden's agreement to these terms further antagonizes Murtry. The explosion also activates the planet's defenses, which shuts down the fusion reactors on the orbiting ships. When the Edward Israel dispatches a conventionally-powered shuttle to begin evacuations, it is incinerated mid-flight; evacuation from the planet becomes impossible. Holden and the settlers alter their plan, seeking refuge in the nearby alien structure, hurrying to get everyone there before the surrounding area is flooded. Anticipating further violent conflict inside the structure, Murtry reaffirms to Wei the prioritization of their survival over Belters, including Holden and Amos. On Mars, Bobbie joins Esai's team as muscle. During a heist, their inside man turns out to have false information as his code fails to get them past a security door. Bobbie risks her life by going outside to climb a maintenance tower and disable the door's hydraulics manually. Tracking Marco Inaros's location, Ashford and Drummer identify an image of him on a Belter ship called the Pizzouza.
437"A Shot In The Dark"Sarah HardingDan NowakDecember 12, 2019 (2019-12-12)
The settlers on Ilus split into different areas of the alien structure, with Murtry and the Earthers hoarding their resources from the Belters while Murtry minimally cooperates with Holden and bides his time. Murtry reveals to Wei that in order to maximize his profit from the situation, he has always intended to eradicate the Belters from the planet. Okoye discovers a condition spreading in the settler population: green micro-organisms are colonizing their eyes, which will lead to blindness. Several settlers are also killed by different larger, parasitic green slug-like creatures. The fusion reactors of the close-orbiting ships remain neutralized by Ilus’ defenses, and the low-orbiting Barbapiccola has mere days before atmospheric drag will pull it out of orbit to burn up in the atmosphere. Finding out that her missing daughter had made her way to the Barbapiccola, Lucia devises a solution to save the ship by tethering it to Rocinante. As information of Marco Inaros's sighting on the Pizzouza makes its way to Earth, Avasarala coordinates an attempted capture. Rather than destroy the Pizzouza with a missile, she orders UNN marines to board the ship to capture Inaros alive, with minimal casualties. However, Inaros is not found; a firefight breaks out, followed by an explosion that destroys the Pizzouza, and kills everyone aboard.
448"The One-Eyed Man"Sarah HardingDan NowakDecember 12, 2019 (2019-12-12)
After the destruction of Pizzouza, Drummer and Ashford both resign from their respective positions, upset that their information led to senseless Belter deaths. Ashford plans to hunt down and kill Marco Inaros independently and asks Drummer to join him, but she declines, weary of "politics". On Earth, Avasarala is blamed and condemned for the Pizzouza fiasco, and her marine general resigns. At a memorial for the marines who died on the ship, Avasarala delivers a heartfelt speech referencing her own son, also an Earth marine who died in the line of duty, killed by the OPA. In a last-ditch gambit to salvage her re-election campaign, she leaks images of the environmental disasters on Ilus/New Terra, drawing public favor for her cautious approach to intergalactic settlement over Gao's eager expansionism. However, Avasarala's husband is alienated by her ceaseless political maneuvering and her use of their son as a talking point. On Mars, Bobbie becomes suspicious of Esai's contact for a mysterious new job and opts out, trying to persuade him to drop the job as well. However, Esai is preoccupied with the potential payout, which would allow him and his family to migrate through the Ring to better opportunities. In orbit around Ilus, the crews of the Rocinante and Barbapiccola successfully tether the ships together in a feat of engineering, saving them from the planet's gravity for a time. Stranded below on the surface of Ilus, Dr. Okoye determines that the large green slugs (which are literally crawling out of the walls all around the alien structure in which the floodwaters have the settlers trapped) secrete a powerful neurotoxin that kills humans on contact. To make matters even worse, all of the colonists are now blind, with only Holden immune. As blind settlers wander too far from their bases, more are killed by the parasitic slugs. Many begin to despair, with Amos in particular showing a major psychological toll though he bonds with Wei. Okoye determines that Holden's immunity is the result of his cancer medication (which he must take for the rest of his life after he was exposed to radiation on Eros); she devises a cure, and is soon able to restore sight for the colonists. After a long absence, Holden has another vision of Miller, who screams at him.
459"Saeculum"Breck EisnerDaniel Abraham & Ty FranckDecember 12, 2019 (2019-12-12)
Murtry orders his crew on the Edward Israel to fire a weaponized shuttle at the Rocinante, hoping to destroy it and the Barbapiccola. Okoye's geologist friend learns of this plan and warns Alex in time for him to destroy the shuttle, though debris endangers Lucia and Naomi and damages the Rocinante. Unable to use half of their thrusters, Alex devises a plan to maintain their orbit by using the Rocinante's railgun as a makeshift thruster. In the alien structure on the surface, Miller reveals that he has overcome his Protomolecule programming; now able to act independently, he seeks to end his tormented, ghost-like existence. He identifies the creatures who created the Protomolecule as “the Builders”, and tells Holden that he found a place on the planet that seems to “kill” the Protomolecule technology, explaining it essentially as unexploded ordnance fired at the planet by the race that destroyed the Builders. Miller leads Holden to a portal in the floor, which transports him to another structure on a different part of the planet, where they find a glowing circle of energy; Miller cannot see it, but Holden tells him it looks like “the eye of an angry god”. Hoping that he can both commit suicide (“If you can call this living”) and also deactivate the planetary defenses responsible for trapping the ships in orbit, Miller seeks to physically inhabit the technological network on Ilus, then deactivate both himself and the planet using the glowing circle. As Holden waits for Miller to integrate into the Ilus network, Murtry (accompanied by Wei) chases after him, seeking to neutralize Holden as the primary threat to the profitability of his claim on the planet. In turn, Amos and Okoye follow as well. As Amos exits the portal, Wei confronts him, and each tries to convince the other to stand down, but neither gives in. Amos reluctantly kills Wei, but is ambushed and shot in turn by Murtry as Okoye flees to find Holden. Hearing from Okoye that Amos was injured, Holden leaves her with the glowing circle before Miller can integrate. She witnesses Miller emerging from the material of the structure as a spiderlike mechanical being and explains Holden left, so Miller asks for her help. Holden confronts Murtry and, after a standoff, incapacitates and disarms Murtry, but spares his life, resolving to put him on trial for his crimes. After Miller is attacked by other mechanical beings operated by the planet, and Okoye hides under the glowing ring to escape a swarm of “bugs” (which fall to the ground, inert, upon contact with the phenomenon), he directs Okoye to maneuver his badly-damaged physical form towards the glowing ring, and Holden returns just in time to see the two of them fall into it.
4610"Cibola Burn"Breck EisnerDaniel Abraham & Ty Franck and Naren ShankarDecember 12, 2019 (2019-12-12)
Miller's plan is a success, destroying himself while completely deactivating the Builder technology on Ilus; Okoye suffers an ominous vision after falling into the glowing circle, seeing something similar to what Holden sees during his passages through Rings. With the planet deactivated, the Ilus settlers are finally able to evacuate, although many of the Belters opt to rebuild their settlement on the planet now that the danger has been neutralized. Holden brings Murtry and a wounded Amos onto the Rocinante to return to Earth's solar system, where Murtry and Lucia will stand trial for their respective crimes. However, after Naomi points out the similarities between herself and Lucia, Holden sets Lucia free, reporting that she died as a result of the suicide shuttle launched from Edward Israel. Heeding a warning from Miller, Holden finds a small sample of Protomolecule still on the Rocinante, which he removes and fires into the sun, using the sample as a proxy to say goodbye to Miller. After Amos recovers from his wounds, he visits the recently-recovered Murtry (who is in custody on Rocinante) and provokes him; when Murtry throws the first punch, a grinning Amos thanks him, then viciously attacks Murtry as revenge for having been forced to kill Wei. As the situation on Ilus becomes one of successful settlement and peace between Earth and Belters, Avasarala's re-election campaign on Earth is ruined; Nancy Gao wins the election and prepares to take over as UN Secretary General-elect. On Mars, Bobbie attempts to stop Esai's deal with a mysterious contact, but fails to prevent an ambush in which Esai and most of his crew are killed. Now certain of a wide-spread conspiracy to steal Martian military technology, Bobbie reaches out to Avasarala for help and to rejoin the team of the defeated leader, who as a lame duck laments Bobbie's poor timing. Ashford tracks down Marco Inaros, independently discovering his connection to smuggled Martian military technology in the process, and boards Inaros' ship. After a shootout, both crews are killed, and Ashford corners Inaros, only to be ambushed by Filip, the son of Inaros and Naomi, who is revealed as his father's right-hand man. Inaros and Filip execute Ashford, then carry out their plan, using asteroids cloaked with stolen Martian stealth technology launched directly at Earth. Unknown to the Inaroses, Ashford recorded their conversation and transmitted it to an unknown party before being blown into space.
