April 27, 2016
On the pocket world, Ghüs and The Will have a brief altercation, in which The Will's right fingers are severed. As Upsher and Doff escape his ship, The Will is dissuaded from killing Squire and Ghüs by a hallucination of The Brand, who tells him that The Stalk was merely an obsession of his, not his true love, and that he should seek direction from "the one chick who calls [him] on [his] bullshit." Marko rescues Hazel from the detention center, but Klara, having developed a place among the prisoners' community, and refusing to be a burden to the couple, declines to leave, telling Marko how proud she is of him. Petrichor, however, escapes with Marko, and reveals to the couple that Alana is pregnant.
As the family readjusts to life following their reunion, Alana and Marko discuss when to tell Hazel about Alana's pregnancy. Sir Robot IV is dismayed to realize that he is having sexual dreams about Alana. Petrichor and Izabel find a common interest. On Wreath, Sophie implores Gwendolyn to allow her to train as a Freelancer so she can finish what The Will started, but Gwendolyn has moved on from that matter, and warns Sophie, who is from the war-torn comet Phang, that any relatives of hers still there need to be evacuated immediately. Meanwhile, dwindling fuel forces the family to land on Phang themselves, where they encounter a family of starving meerkat-like people.
The family has been staying on Phang for six months alongside the tribe of meerkat-like locals they encountered upon landing, with Alana acting as a den mother. Marko and Petrichor observe the ongoing war on the comet from a safe distance. Hazel rebels against Izabel, prompting her to offer Sir Robot IV help in leaving Phang to reunite with Squire. On Wreath, The Will seeks Gwendolyn but instead meets her wife, Velour. Izabel heads to an abandoned Robot embassy where she comes across a two-headed Freelancer known as The March whose weapons can affect her. When she refuses to reveal the whereabouts of the family, The March stabs her, causing Izabel to disappear, resulting in Hazel experiencing a deep pain.
Hazel expresses her distress to the family when she insists that she can no longer feel Izabel's presence. After a brief argument between Marko and Sir Robot IV, Petrichor volunteers to track down Izabel. On Wreath, The Will receives news from his handler that the Freelancer agency is closing down and that his license to kill as an assassin has been revoked. A conversation with Kurti leads Hazel to experience her first kiss. The March encounters the dying corpse of a Robot ambassador while exploring the embassy and discovers cryptic information regarding the fates of all the inhabitants on Phang.
Hazel and Kurti share a conversation while viewing the dreams of Sir Robot IV. Marko questions the sudden retreat of Wreath military forces and briefly lashes out at Jabarah over her insistence to use weapons during an eventual conflict. The March gets visual confirmation of Marko's whereabouts. Gwendolyn has a clandestine meeting with Special Agent Gale from Landfall and presents him with a mysterious gold box. The two engage in a heated discussion over the fate of Phang as Sophie eavesdrops on them. Petrichor encounters a bluecap in the form of a giant mushroom, who tells her that Phang is deserted because it is heading toward a Timesuck. After having his sleep disturbed earlier by Kurti and Hazel, IV samples some Fadeaway and confronts Alana, where in his drugged state, he admits the reason for his attraction to Alana before transforming his arm into a cannon and pointing it at his head.
Petrichor warns Jabarah of Phang's imminent collision with the Timesuck. During the standoff with the drugged Robot IV, Marko and Robot IV are knocked unconscious. The March arrives outside the family's treehouse and holds Kurti hostage. On Wreath, Gwendolyn, Sophie, and Lying Cat reunite with The Will and Sweet Boy, where The Will offers Sophie the chance to become a Freelancer. Sophie and Lying Cat decide to remain with Gwendolyn, after which The Will and Sweet Boy depart. On Phang, Hazel uses magic to create a distraction that allows Kurti to escape before Marko kills The March.
On Wreath, Gwendolyn instructs Sophie to keep the information she knows about Landfall and Wreath secret from Velour. On Phang, Sir Robot IV is kept bound by Marko while Petrichor manages to procure enough fuel to launch the rocketship treehouse off the comet. Jabarah refuses to leave with the family, believing the creator will protect her and her tribe. Elsewhere, The Will is confronted by a masked individual who kills Sweet Boy and shoots The Will in the stomach, telling him that The Will murdered someone the stranger loved. A rogue spaceship piloted by the Landfallian henchmen of Special Agent Gale shoots down a nearby Robot-controlled vessel and activates the gold box Gwendolyn gave to them. The device releases an energy force that causes the Timesuck to expel a torrent of black liquid that begins to engulf Phang. In the ensuing chaos, Petrichor launches the treehouse out of danger but causes Alana to experience a fall that results in a miscarriage. The arc ends with scenes of Kurti and the other locals of Phang consumed in the Timesuck's deluge.
Following the destruction of Phang and prompted by Alana's miscarriage, the family heads to an outpost planet at the westernmost edge of the universe called Pervious, which is controlled by Landfall. Posing as a couple, Alana and Sir Robot IV encounter the Doctor Sherriff of the planet's Abortion Town, who informs them that she cannot perform an abortion on Alana due to Landfallian laws, but directs them to an illegal part of Pervious called the Badlands where they would be able to remove Alana's fetus. Afterwards, Alana banishes Sir Robot IV and forbids him from returning to the treehouse. Hazel and Petrichor have an awkward conversation about body issues. Alana returns to inform Marko of her plans to journey to the Badlands alone, but Marko insists on joining her. Animated creatures made out of excrement suddenly appear nearby and attack the family. To her surprise, Alana manages to defeat the dung people by shooting flames from her hand.
A local family of Pervious bandits ambush and kill a Landfallian soldier and his pregnant lover on their way to an abortion. The bandits find footprints leading deeper into Pervious territory and decide to follow the tracks. In the rocketship treehouse, the family is coming to terms with Alana's newfound magical abilities while realizing the need to have the fetus removed as soon as possible before it threatens her life. Hazel insists on coming with her parents to the Badlands, while Petrichor is entrusted with Marko's translation ring and tasked to defend the treehouse in their absence. Alana, Marko, and Hazel stow away on a Landfallian cargo train en route to their destination. The family of bandits manage to trace the footprints, which lead to Petrichor standing guard outside the treehouse. After waking from a nightmare, Alana is shocked to discover a young boy with hybrid features from Wreath and Landfall is claiming to be her son.
Petrichor confronts the family of Pervious bandits outside of the rocketship treehouse and ends up outnumbered and incapacitated. Aboard the cargo train, Marko explains that the hybrid boy they are seeing is a product of Alana unconsciously casting a powerful projection spell used by the High Clerics of Wreath to determine future outcomes of certain events. The boy introduces himself as Kurti, and Hazel awakens in time to see and interact with the projection of her would-be younger brother. Marko warns that the longer Alana sustains the projection of Kurti, the higher the risk of her getting cardiac arrest. Petrichor manages to injure the matriarch of the bandit family and is subsequently saved from death by the arrival of Sir Robot IV. Alana suffers a heart attack just outside of their intended destination and the projection of Kurti fades away. Marko urges Hazel to perform a spell that mimics the effect of defibrillation, and Hazel successfully revives her mother back to life. The family is then greeted by the presence of a wolf-like creature with bloodied paws, who informs them that they are "in such very good hands".
The family of Pervious bandits depart after Sir Robot IV orders them to leave the premises under the threat of death, though Petrichor lashes out at Robot IV for his act of heroism in rescuing her from harm. During their tense exchange, Robot IV informs Petrichor that he is aware of her transgender identity and also discloses his sexual fluidity. In the Badlands, the wolf-like creature introduces herself as Endwife to Marko and Hazel and invites them into her home, where it is revealed that she is a mother to a litter of pups. Endwife and Marko engage in a difficult conversation about their individual views on abortion before she begins to remove the fetus from Alana's unconscious form. The projection of Kurti reappears to Hazel briefly, and she sings to him a lullaby that Izabel once sang to her until he fades away. Back at the treehouse hideout, cultural and political tensions between Robot IV and Petrichor come to a head when the pair unexpectedly ends up kissing passionately as dawn begins to break on the horizon.
Diverging from the events happening on Pervious, the mysterious masked individual who previously attacked The Will–now known by his real name, Billy–at the end of the previous story arc has taken him hostage within a massive jellyfish-like spaceship floating through interstellar space. The masked character introduces and reveals herself as Ianthe, an alien diplomat and the former fiancée of a security specialist that Billy killed under the employ of Mama Sun from Sextillion many years ago. She reveals her plans of revenge and torture to Billy as retribution for killing her deceased lover. Using a special memory extraction apparatus, Ianthe runs through a selection of Billy's past memories until she comes across a scene featuring Gwendolyn that mentions the truth about Marko and Alana. Blown away by this revelation and believing it will lead her to immense wealth and fame, Ianthe changes her plans in order to hunt down Alana and Marko, and forcing Billy to participate in her quest to track down the runaway family.
On the unnamed pocket world, Ghüs continues to look after Squire and has provided sanctuary for Upsher and Doff. Faced with a severe food shortage for several months and Doff delirious with starvation, Ghüs is forced to hunt down a wild creature known as a Dread Naught, which is invisible to others but can be seen by Robots. Due to the nature of the creature they are going to capture, Ghüs reluctantly allows Squire to join him on the hunt, and the pair bond through a deeply personal conversation as they journey deeper into the woods. They eventually encounter the Dread Naught, but Squire cannot bring himself to kill the creature and it escapes. The pair make their way back to the homestead where they are greeted by the welcome arrival of Sir Robot IV, Marko, Alana, and Petrichor bearing food. IV apologizes to his son for the delay in his return and introduces him to the runaway family, with Hazel now displaying her capability for flight. The arc closes with Hazel and Squire getting to know one another as their respective parents look on with fondness, and Hazel's narration revealing that Squire would become her brother.
