List of Eureka episodes
The following is a list of episodes for the American science fiction drama Eureka. In addition to the regularly televised episodes, there is a short webisode series called "Hide and Seek", which is available on Syfy's Eureka homepage.
The episodes in the first season were not aired in the order intended by the show's creators. Thus, there are some small inconsistencies, but such inconsistencies are minimal and were intentionally controlled. In podcast commentaries, the show's creators and star Colin Ferguson confirm that the production order was in fact the order in which they intended the show to air, but the network executives changed the order to try to place stronger episodes earlier in the run to help attract viewers.
The creators were able to make minor changes in editing and sometimes dubbed dialogue in later episodes (for instance, they removed the explicit mention of Zoe's first day at school) to minimize audience confusion.
As of July 16, 2012[update], a total of 77 episodes of Eureka have been aired over five seasons. A fifth season was announced on August 17, 2010, consisting of 13 episodes. On August 8, 2011, Syfy announced that season 5 would be the final season. On February 16, 2012, Syfy announced that the show's fifth and final season would premiere on April 16, 2012.

Season 1 (2006)
|Title||Directed by||Written by||Original air date|
|1||1||"Pilot"||Peter O'Fallon||Andrew Cosby & Jaime Paglia||July 18, 2006|
While transporting his delinquent daughter back to Los Angeles, U.S. Marshal Jack Carter crashes his car near Eureka. There, he assists in a case involving a tachyon accelerator. The town begins to experience time and space anomalies, a child is nearly killed, and a herd of cows is lost. When Carter investigates these incidents, Jim Taggart kidnaps him and Carter meets Allison Blake, who shows him Global Dynamics and the real side of Eureka. The accelerator is eventually found, and the scientist who built it dies trying to shut it off, and the military comes in and quarantines the town.
The rift caused by the tachyon accelerator can be stopped if another particle collision can occur, but a large quantum physics problem must be solved (half of it went missing while the anomalies occurred all over town). With the help of Jo, Carter sneaks out of the heavily guarded GD and grabs Allison's autistic son, who solves the problem, another collision occurs, and Eureka—and Earth—is saved. In the end, Carter gets a promotion like he wanted, but just not the one he expected: he becomes the new sheriff of Eureka after the old one retires.As a pilot, the sets were not final designs. The Global Dynamics sets were completely changed for the production series, including new exteriors and a different, more angular logo. The director of GD - Warren King - was also replaced with Nathan Stark in the following episode, nominally due to the security breach in section 5, although he is never mentioned again.

|Spencer is apparently abducted by aliens then returned to Earth the next day inside a crop circle, while Fargo, Jo, Vincent, and Taggart start to act strangely. The town is also visited by a congressman whose committee is responsible for the town's government funding. It turns out that Spencer, Fargo, Jo, Vincent, and Taggart were watching a movie that Spencer hacked from a satellite, which he bounced off a GD military satellite, the purpose of which was to cause paranoia in the enemies of the USA. While watching the movie, the paranoia 'beam' is transferred to them, and they begin to think the movie is going on around them, and believe that the senator (Garwin Sanford) is host to an alien and kidnap him. Carter is able to stop them from cutting the 'alien' out of him and gets them to surrender.|

|6||6||"Dr. Nobel"||Jeff Woolnough||Dan E. Fesman & Harry Victor||August 22, 2006|
Carter must help an aged scientist recover his memory in time to stop a doomsday device from destroying the world. The old scientist, Dr. Thatcher, has not been the same ever since he didn't win the Nobel Peace Prize for creating a mutual assured destruction (M.A.D) device, which fires a beam of irradiated uranium isotopes at a mirror on the moon, bouncing back at Earth to hit another target on its surface after Earth has rotated sufficiently (mostly likely causing World War III, since the default target was chosen during World War II).Carter uses a hologram presentation to convince Dr. Thatcher that he won a Nobel prize, and the scientist regains his right state of mind. Dr. Thatcher attempts to turn off the device, but since Henry had earlier cut the blue wire while attempting to deactivate the device on his own, the computer initiates a dead man's protocol—the automatic firing of the weapon on a five-minute timer. Unable to stop the device, Carter drives his Jeep into it, causing the weapon to just barely miss the moon and hit a satellite off of Jupiter.
|7||7||"Blink"||Jeffery Levy||Andrew Cosby & Jaime Paglia||August 29, 2006|
|A mysterious death leads Carter to suspect foul play, but some individuals want to ensure that he does not delve too deep.

|Nanoids designed to repair living tissue escape from a Global Dynamics lab and threaten to overrun Eureka. The threat gets worse when they gain the ability to take the form of living beings. It is found that the nanoids communicate on the same frequency as Stark's newest gadget, which allows him to uplink to the computer remotely. So the nanoid-constructed androids take the form of Stark and start doing whatever he dreams about in daydreams, which includes world domination. Carter figures out how to destroy them, so he evokes an emotional response from Stark by kissing Allison. The androids come and using Spencer's new super-speaker, which makes a sound low enough that the communication between the nanoids ceases and the many Stark-androids fall apart into dust.|

Teleplay: Jaime Paglia & Andrew Cosby
|October 3, 2006|
|Nathan Stark is given the opportunity to investigate "the Artifact." After it is tested (with Kim's help), we cut to 2010 and Eureka is a very different place. Stark is a billionaire in California, Henry is married to Kim as well as the principal of Tesla High school and the head of Global Dynamics. Carter and Allison are married, and Allison is pregnant. Zoe is the valedictorian of her class, which is graduating that day. Jo and Taggart are dating. But soon problems start to appear all over town: things that the town has experienced in the past 4 years start to happen again, a tornado nearly destroying half of downtown Eureka. Also, a body is found in Section 5, near the Artifact. They test it and find that the body belongs to Kim Deacon, Henry's wife. Henry explains that back in 2006, during Stark's test on the Artifact, Kim was extracting a sample when an explosion occurred, killing her. Henry then used Walter Perkins's tachyon accelerator to go back in time and stop her from dying. This new timeline caused all of the anomalies. The past must be fixed. Stark comes to town to help with the tachyon accelerator. Carter goes back to 2006 and stops Henry from saving Kim in the explosion. The timeline is fixed. We also learn that Beverly had implanted a chip in Nathan's neck so that the Consortium can gain second-hand access to the Artifact.|

|Title||Directed by||Written by||Original air date|
|13||1||"Phoenix Rising"||Michael Rohl||Jaime Paglia||July 10, 2007|
|A solar eclipse happens in Eureka. Following the restoration of the timeline, Carter and Henry must adjust, while Allison gets Nathan's job, and citizens of Eureka start to spontaneously combust. Three of these victims are scientists, all of them having little to no relation to one another. One of them is Kevin's (Allison's son) therapist. Kevin hints that when he went to therapy, he would sometimes go to "the man downstairs". Carter tries to get Henry to help him adapt more to the timeline. Carter follows many leads to the possible deaths, he even suspects Henry at one point, also blaming Vincent's five-alarm chili. Through investigating he finds out that all three scientists were in a lab adjacent to the Artifact during the explosion, and radiation from the explosion infects them, and later causes the body's electrical system to overload. They also discover that Kevin was in the lab as well, but he is unaffected. They conclude that Stark was infected, too, so Stark (who no longer works at GD) sneaks in and goes to the Artifact chamber, just to find that it is dead: instead of a fireball, the Artifact now looks like a mass of roots. They get Stark into a lab and attempt to cool him down, they discover that they can stop him from combustion by electrically shocking his brain. They do this and it nearly kills him but he is brought back, safe from combustion. The episode ends with Henry erasing Carter's memory of the alternate timeline, and Henry then destroying the memory erasing device, saying he is never going to forget.|

Fargo is caught inside a forcefield that is continually expanding. It was placed on him by a man who works in the GD Vault. The shield pushes everything away from it, and is only going to keep on growing and growing. Carter learns that the last time this happened in Eureka, the man inside the shield had to be dropped into a 2-mile deep pit, and then a 3-megaton nuclear bomb was dropped on him. This is about to happen to Fargo when the shield dies, its power source depleted. However, the device starts back up, draining power from Fargo himself, meaning Fargo will eventually die. Carter realizes that sound can past through the shield, so Carter uses a super sonic pulse to temporarily kill Fargo by stopping his heart. The shield collapses and they resuscitate Fargo.|

After using a self-therapy device, Carter experiences his fears where the inhabitants of Eureka are disappearing one by one. When they disappear, no one remembers them. Eventually only Carter and Zoe are left in town and Carter realizes that he is trapped inside the therapy device. Seeing no other choice, he drives himself and Zoe right into one of the anomalies that always appears when someone disappears, and he wakes up.

At first, they suspect a scientist who tried to use space junk as a weapon. Then, at the high school science fair, Zoe messes with a rival's project, an array, and all metallic things are drawn to it. They discover that an array of a similar design is on top of GD, used to take deep-space photos. It was made by the mother of the student who created the smaller, original version.

The tunnels are where water is filtered, and cool air for air conditioning is made. The scientist in charge of the tunnels stumbled upon some old Native American bones and was exposed to a peptide that made him irresistible to his wife, who locked him in his own house. But before that, the scientist had visited Taggert's lab, when Carter went into the lab, some of the peptide rubbed off on him. When Carter later went into the tunnels, he found the bones also and was exposed to even more of the peptide. Carter is attacked by over twenty women. Soon the air conditioning is fixed, the pressure explosions (which was supposed to move water up pipes) stop but, soon, the peptide is in the air of Eureka, pumped out by the air conditioning.

|Success comes at a price, as several citizens of Eureka discover when the DOD sends corporate fixer Eva Thorne, reputed for completely revamping more Fortune 500 companies than anyone else, to town during an Anti-Missile test that sees the target drone named Martha threatening Eureka. Martha terrorizes the town, blowing up the Viper (a weapon that shot down all other drones like her) and stalks Carter, destroys Carter's car, and attacks Carter and Jo at the sheriff's office. They discover that Martha went from having the mindset of a toddler to the mindset of a teenager, and find out that the wife of the scientist who built her increased Martha's intelligence. At Cafe Diem Martha befriends Zoe and attacks Thorne and her escort, the suck-up (and Fargo's arch nemesis) Larry. Larry is knocked unconscious. Martha is taken to GD. Carter and Jo investigate and find a remote control device on her. They discover that Larry put the device on her so he could control her and impress Thorne. However, with her teenage mindset Martha did not care for being controlled and attacked him. At Global Dynamics Martha wakes up and releases other drones similar to her. The fleet of drones heads toward Eureka, and begin taking down the EM shield that would keep them inside of the Eureka city limits. Thorne calls in a squadron of F-16's to stop the drones just in case they escape. Carter, Stark, Fargo, and Allison think that Martha just wants room to breathe, and she feels that she cannot do that inside of the EM shield. But Martha may also be trying to prove herself as being independent and may plan world domination, which would cause World War III. So they purposefully take the EM shield down, hoping Martha will see it as an olive branch.

|A doomsday weapon built in the abandoned military complex is discovered, as is the secret Thorne wants to stay hidden – she's 107 years old, real name Mary Perkins, and was involved in a pre-Eureka research project that developed the first atomic bombs (using radioactive material from meteorites). Meanwhile, Jo and Zane get stuck together, literally, and Zoe's life is imperiled by the aging syndrome that killed Mary's colleagues which she got from slipping in that puddle. Allison is found to be pregnant with Nathan's child. Thorne sacrifices her only chance for a cure for her condition to save Zoe, but the radiation that caused the aging condition is released into the town. The team realizes that the scientists managed to create a cure: the doomsday bomb in the bunker was a fail-safe to neutralize the radiation if it ever got out and the scientists ran out of time to use it on themselves. The bomb is triggered and the town is saved. Meanwhile, Jo and Zane are finally freed and renew their seemingly failing relationship. After Jack lets Thorne go to find a new life as he feels she's a victim too, General Mansfield tells Carter that his services are no longer needed by the town of Eureka.|

When Andy refuses to help due to low chances of success, Carter volunteers and gets close but fails. However, Andy, inspired by Carter's bravery disregards the odds and saves him. Working together they save the day, doing a job that neither of them could have succeeded in alone. Afterward, Andy realizes that Eureka is better off in Carter's hands and exploits a loophole in the town charter to have him reinstated stating that after calculating the odds, he believes Eureka has the best odds of survival with Carter as sheriff. At the end of the episode an alien object is detected heading straight for the town.|
|35||10||"Your Face or Mine?"||Colin Ferguson||Jaime Paglia||July 17, 2009|
|Carter must take the bi-annual D.O.D. re-certification test in order to remain sheriff of Eureka. The test takes 48 hours and the test is conducted completely isolated from the rest of the town. Jo passes her test with a perfect score, only to be disappointed when Zane tells her that no-one is perfect. She then fills in as active sheriff while Carter is taking the test, as well as taking care of Zoe while Carter is otherwise occupied. Allison wants to put a new security measure into effect that uses a DNA scan to grant or deny access to various points of Global Dynamics. Henry doesn’t want to install the new devices, so Jo is called in as the deciding vote. Jo decides to have the devices installed and is the first one scanned for identification, but the device malfunctions and nearly electrocutes her. When Jo comes to it is discovered that someone had stolen a critical piece of the device. Allison wants to pull Carter out of his test to have him help find the thief, but Jo insists that she can track down the thief herself. When Jo asks Henry about the missing piece of equipment, he tells her that he is also missing an important piece of equipment. Leaving Henry to ponder a possible link between the two stolen items, Jo heads for the Smart House to help Zoe with homework. Jo finds that walking a mile in Carter's shoes is proving to be a challenge, especially when Zoe wants to blow off work and go to karaoke night at Café Diem. Jo's still feeling the effects of her near-electrocution and forbids it, wanting nothing more than to sleep. Zoe uses this as an opportunity to sneak out. Jo soon catches Zoe performing at the Café. Yet instead of grounding her, Jo joins in the fun, drinking too much as she sings and flirts with Fargo. Jo ends up kissing Fargo just as Zane enters the Café. Jo insists that she's fine, but Allison and Henry worry about Jo's state of mind after she begins behaving more erratically. Zane is worried about her behavior and convinces Fargo that she would not have kissed him if she had been her normal self. A third theft then occurs and the DNA scanner identifies Jo as the thief. Only Jo knows that someone is stealing her identity, gene by gene. Trapped in that person's body, Jo has to convince a skeptical Zane of her true identity. Fargo confronts 'Jo' getting the thief to admit their true identity. A worried Zane looks on as Henry attempts to stabilize Jo's DNA. As she shifts back to her own form, Jo ask Zane how she looks, to which he replies 'Perfect'.|

|Several mysterious events take place after Dr. Drechmeyer is supposedly contacted by his late mother, a famed clairvoyant. He thinks that the readings on his new energy-measuring device indicate the presence of ghosts. His lab partner and ex-wife, Mary-Beth Curtis, fears his obsession will cost them their funding, but something strange is happening. Carter finds a car parked in the middle of the road, but its driver - a spirited and beautiful new arrival, Dr. Tess Fontana - denies leaving it there. Tess leaves Carter annoyed, yet intrigued. Meanwhile, Carter's sister, Lexi, enjoys her new "Invis-Apparel" maternity shirt courtesy of GD, which completely hides her pregnant tummy. It also proves useful when the twins' world-traveling father arrives in town unannounced. Lexi hides her condition, not sure that Duncan is fatherhood material, much to Zoe's disapproval. Later, at Café Diem, Carter finds a highly agitated Dr. Drechmeyer claiming the high readings he sees prove the spirits are active. Suddenly, various objects begin to fly about and Carter has to tackle Tess Fontana to keep the espresso machine from decking her. Then, to Carter's surprise, Allison arrives and greets Tess with open arms. They are old college friends and she's been brought in for a secret project. Following another energy burst, Allison admits that GD has decided to re-open Section 5 under Tess's oversight. And she wants Carter and Tess to work together to solve the paranormal activity — even though they clearly can't stand each other. When Tess gives Carter a tour, they encounter a strange device, and some odd sensations, in one of the labs. Leaving the area, they realize that no one can see or hear them. This causes them to ponder whether they are dead; however, Tess believes they've somehow crossed into another dimension. Returning to the lab, they find Dr. Johnson recovering from an unsuccessful attempt to break out. His research on inter-dimensional travel created a temporary door into the Fifth Dimension. Unless they can re-calibrate Johnson's device before Henry and Allison unknowingly shut it down from the other side, the trio could be trapped inside forever.|

Carter and Tess find a container for Ed's radiation-devouring microorganism that is now empty. It seems the blob had Ed for lunch and has now gone out for dinner. "Team Green" would be a likely target but Duncan, returning to confront Lexi, concocts a mud bath to cure their radioactive condition. In a scene reminiscent of "Psycho", the radiation-starved blob attacks. Carter comes to the rescue, but the mutating green menace retreats down the drain and heads for Eureka's last source of Globidium — the Smart House.

Afterwards, the hard drive containing ADA (Advanced Disaster Accuator) is destroyed by a liquid nitrogen pipe rupture. As the day continues, GD begins to experience malfunctions and breaches identical to the simulation. They realize that ADA programmed commands into the GD mainframe, to make the previous simulation "authentic" by actually realizing the events of the simulation, and then destroyed itself so the commands could not be overridden. Meanwhile, Zane helps Fargo connect with Holly in the mainframe, whose full consciousness had been trapped in the Matrix after her neural patterns were disconnected from her body. Zane develops an adaptive waveform forcefield to hide the Matrix and not repeat the events of the last episode. Fargo manages to get in a few minutes with Holly before being called out to supervise the actual disaster. Allison and Jo also must deal with the emotional awkwardness/trauma of the possibility of Jack winding up with Jo if Allison were gone. The final piece of the scenario is a missile attack that ADA launches from a nearby missile silo. When the EM shield does actually fail, Zane uses his adaptive waveform shield to stop the missiles from destroying GD and the town. Jack and Fargo set it up at the exact coordinates specified by Henry, and they successfully save the town at the last second. Later, everyone gets together at Cafe Diem to celebrate. After the cafe, Fargo goes back to the Matrix to face a hard reality and tell Holly that she is technically dead. This saddens Holly and the two hold each other for comfort wondering what is next.|
|71||7||"Ex Machina"||Michael Robison||Kira Snyder||1.97||June 4, 2012|
|Henry delivers a memorial service for Holly, but Fargo is more interested in seeing her on the Matrix. Major William Shaw arrives to GD to install a new security system (PANOP) on behalf of the DOD and to take away the Matrix photonic computer. Fargo and Zane tell the others about Holly being in the Matrix, but Jo doesn't believe them. Zane, Fargo, Carter, Henry and Allison try to save Holly without alerting Shaw of her presence, but she interferes with the PANOP and a systemwide error causes Shaw to activate a "Level 6 Polymorphic Antivirus Purge" which could delete Holly forever. Holly tries to save herself by running into the computers of GD ending up in a laser, which she uses to write a message. Jo finally accepts it and buys them time to save her. After thinking that they have lost Holly, Henry reconstructs the interface and downloads her into Sarah's computer. The PANOP is disabled but Shaw still takes the photonic computer away.|

Allison and Carter become trapped in a leaky submarine at the bottom of a lake. Carter and Allison get in a big fight but soon Allison and Carter ask Henry to marry them now before they are teleported to GD, with Jo as the maid of honor. Holly's programming is too much for Sarah's computer to handle and Holly starts to fade away. Zane is put in charge of Section 5. Zane sets to work on a computer big enough to save Holly's programming.|

Allison tries to find out why and how to revert him back to normal.|
|74||10||"The Honeymooners"||Joe Morton||Eric Tuchman||1.61||June 25, 2012|

There, Jack encounters a file hidden in a safe which he gives to Andy since it is his honeymoon. Andy and Jo discover that the former sheriff was investigating a spy network in Eureka. Holly's mind is downloaded into her bio-printed body but she encounters some technical difficulties that could threaten her existence. Due to Andy and Jo's investigation, Grace is revealed as a former spy, but it turns out she's protecting Henry, whose former self in the timeline was the one who introduced her to Beverly. Zane manages to reinitiate Holly's neural pathways and save her. Carter and Allison reach a compromise.|
|75||11||"Mirror, Mirror"||Mike Rohl||Bruce Miller||1.59||July 2, 2012|

Holly receives a mysterious message triggering an alarming change in her behaviour, and she uses it to change Andy's too. Henry wants to surrender himself, but Grace convinces him to not do so. Jo tries to sabotage the DOD's investigation to help Henry. Allison discovers Holly using the body-printer and becomes suspicious. She ropes Henry into finding out. Zane finds the message and shows it to Allison. Carter and Allison realize Andy and Henry are behaving oddly. Jo realizes that she has seen the message before, in the matrix. She's lured to the forest, when she's attacked by a copy of herself. Zane is arrested for tampering with the evidence files. Carter finds the missing control unit but also the body-printer Holly is using to create new bodies to replace the people of Eureka. He sees the already replaced Henry and Jo, unconscious. Holly knocks him unconscious too.|

|1.56||July 16, 2012|
|After the DOD shuts Eureka down, Zoe comes to visit before her graduation, and the entire town is threatened to be ripped apart by unstable wormholes, while Fargo tries to save Eureka from closing down. Henry tries to save Grace, going as far as to ask Beverly to help her. Dr. Taggart tries to catch his super-smart dog. Holly deals with her loss of memory, and restarts her relationship with Fargo. To stop the wormholes, Carter is forced to jump into one wearing one of Fargo's devices. The Secretary of Defense calls Fargo to tell him they've sold Eureka. Grace comes back because someone gave the feds an anonymous tip on Sen. Wen in exchange for her freedom. Jo asks Zane to marry her and he accepts. Dr. Grant comes backs as Dr. Rockwell and reveals he's bought Eureka on Fargo's pleading to keep it running. His only condition is that Henry accepts to become the new director, and he agrees. Allison tells Carter that she's pregnant. While Jack takes Zoe back to college, Jack and Zoe pass themselves 5 years in the past as they first come to Eureka, mirroring a similar scene in the pilot.|
Hide and Seek (2006)
|1||"Prologue"||July 25, 2006|
|In the woods, a group of teenagers sneak up to Jo's house with a camera, hoping to catch a free show. As they watch, a mysterious creature attacks them.|
|2||"Part One"||July 25, 2006|
|The video of the teenagers being attacked is now on the Internet, and Zoe has linked it to her homepage in an attempt to get some answers. Jack believes it to be a drunk in a monkey suit, but a visit from Allison confirms it to be quite real. Elsewhere, Taggart is happy to have found something after so many years.|
|3||"Part Two"||August 1, 2006|
|In the woods, Jo and Carter search for the creature. Carter mentions that he asked Stark what it was, only to be hit with the all too-common "classified". The two find a gutted bear, and bag a claw they find in its stomach. Elsewhere, Taggart is hunting the creature. It chases away Fargo, who has accompanied Taggart, and Taggart goes on the hunt.|
|4||"Part Three"||August 8, 2006|
|Taggart, still searching for the creature, ends up being knocked out by his prey. Meanwhile, Allison and Jack are discussing the creature while Allison changes a flat. Jack mentions that he has given the claw to Henry for analysis. The creature begins sneaking up on Allison during their conversation. Allison notices this, and asks Jack to come help. The creature then attacks, chasing Allison into her car. A gunshot goes off as the screen goes dark.|
|5||"Part Four"||August 15, 2006|
|Taggart comes to, having survived his encounter with the creature. He finds Fargo's broken glasses, and assumes the scientist to be dead. At Henry's garage, the creature is now in a body bag, having been shot by Allison. A team from Global Dynamics is on its way to pick it up. Henry explains that the creature has DNA that only Neanderthals should have, and that the claw Jack gave him doesn't belong to the one Allison shot. In the woods, something lets out a loud roar.|
|6||"Part Five"||August 22, 2006|
|At the sheriff's office, Fargo stumbles in, tired and bruised. He explains that the creature is supposedly the "Missing Link". At Global Dynamics, he also notes that the creature Allison shot is not the one that attacked him. Jack tries once again to get Stark to explain what the creature is, but Stark merely says that Taggart can explain it better. As Jack and Fargo leave to find Taggart, Stark notes that Taggart is one "stupid brilliant son of a bitch." In the woods, Jack and Fargo hear the creature roar as it closes on them.|
|7||"Part Six"||August 29, 2006|
|Having momentarily avoided the creature, Jack and Fargo find Taggart, who appears injured. Jack asks Taggart to explain what the creature is, since Taggart had been running the project that created it. Taggart, speaking somewhat incoherently, claims that his funding was cut off on the verge of the breakthrough, and says that they claimed it was too early for human trials. When questioned about this by Jack, he roars.|
|8||"Part Seven"||September 5, 2006|
|Taggart has apparently transformed into some kind of monster (though the scene is from his point of view) and is preparing to attack Jack. As Jack tries to reason with Taggart while reaching for his gun, Fargo creates a distraction, giving Jack the opportunity to shoot Taggart. At Global Dynamics, Taggart appears physically human, though he is still acting like an animal. Fargo says that they've put him on gene therapy, and that he'll be normal in a few weeks. Stark still won't explain just what has happened. Since the incident seems to be over, everyone goes home. At Jo's house, just after she closes her curtains, what appears to be another creature walks by.|
