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. There are some small inconsistencies because of this, but such inconsistencies are minimal and were intentionally controlled. In podcast commentaries with the show's creators and star Colin Ferguson, they confirm that the production order is in fact the order in which they intended the show to air, but the network executives changed the order to try and 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 September 19, 2011 (2011 -09-19), a total of 63 episodes of Eureka have been aired over four seasons. A fifth season was announced on August 17, 2010.[1] The season will consist of 14 episodes.[2] On August 8, 2011, Syfy announced that season 5 would be the final season.[3]

1 1 "Pilot" Peter O'Fallon Andrew Cosby & Jaime Paglia July 18, 2006 (2006-07-18)

While transporting his delinquent daughter back to Los Angeles, U.S. Marshal Jack Carter crashes his car near Eureka. He assists in a case involving a tachyon accelerator, built by an amateur scientist, and is hired as the Sheriff. The town begins to experience time and space anomalies, a child is nearly killed and a herd of cows is lost. When Carter investigates Jim Taggart kidnaps him and he meets Allison Blake who shows him Global Dynamics and the real side of Eureka. Eventually the accelerator is found and the scientist who built it dies trying to shut it off. The military then 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 (for half of it went missing while the anomalies occurred all over town) so Carter sneaks out of the heavily guarded GD (with the help of Jo) and grabs Allison's autistic son who solves the problem, another collision occurs and Eureka, and Earth, is saved.

As a pilot, the sets were not final designs. The Global Dynamics sets were completely changed for the production series, including a different, more angular logo, and new exteriors. The director of GD was also replaced with Nathan Stark in between this and the following episode, nominally due to the security breach in section 5, although he is never mentioned again. 
2 2 "Many Happy Returns" Jefery Levy Andrew Cosby & Jaime Paglia July 25, 2006 (2006-07-25)
Carter and the rest of the town are surprised by the arrival of Susan Perkins, a woman whose funeral they've all just attended. Nathan Stark, Allison's ex-husband, becomes head of GD. Meanwhile an amorphous being causes electrical disturbances all over town. The being is found to be the scientist who created the tachyon accelerator and is now caught between seconds, and the woman who died is found to be a clone, and the woman who showed up is the real one.

August 1, 2006 (2006-08-01)
When a world renowned scientist arrives in Eureka, Jack and Henry suddenly find that they cannot account for blocks of time. The scientist uses a device Henry created that emits an EM pulse that messes with people's electrolytes in the brain and causes them not to form short term memories.

6 6 "Dr. Nobel" Jeff Woolnough Dan E. Fesman & Harry Victor August 22, 2006 (2006-08-22)
Carter must help an aging 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 never won a Nobel Peace Prize for creating the mutually assured destruction device, which would fire a beam of irradiated uranium isotopes at a mirror on the moon and in turn destroy the planet, so Carter uses a hologram to convince Dr. Thatcher that he got a Nobel, and the scientist is no longer senile. Dr. Thatcher attempts to turn off the device, but since Henry had earlier cut a particular wire while attempting to deactivate the device on his own, the countdown to the device firing continues. Unable to stop the device, at the last moment before it fires Carter hits it with his jeep, knocking it out of alignment so that the beam from the machine barely misses the moon. 
7 7 "Blink" Jeffery Levy Andrew Cosby & Jaime Paglia August 29, 2006 (2006-08-29)
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 (2006-10-03)
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.

13 1 "Phoenix Rising" Michael Rohl Jaime Paglia July 10, 2007 (2007-07-10)
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.

As the computer at Global Dynamics reboots on the occasion of Allison's start as the new director, the disappearance of a "Category Red" device leads to an unlikely alliance between Carter and Stark. Fargo is caught inside a forcefield that is continualy 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 recusitate Fargo.

He talks to Zoe, who is very angry with him, because she is going to have to leave with her mother. 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. Henry and Allison inform him that usually the device lets people go whenever they want, but the concussion he'd had was interfering with the device. Abby, Carter's ex, decides not to take Zoe, since she realized that it seems to be one of the only places that Zoe fits in.

Space junk is massing over Eureka, forming a giant debris cloud that threatens to destroy the town and its inhabitants. Carter must find what is drawing it, and why, before disaster strikes. 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. When the array bounces off of the electromagnetic shield around GD, it creates one giant magnet. Carter and the GD scientists are able to make the space junk dissolve in the atmosphere. 
18 6 "Noche de Sueños" Eric Laneuville Jaime Paglia August 14, 2007 (2007-08-14)

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. The drones and the F-16's charge each other and Zoe (understanding what Martha is going through) talks to Martha over the radio and is able to convince her to come back to Eureka. The drones disengage and return to Global Dynamics

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.

Jo 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 Zoe 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. 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.

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.

However, cheaters never prosper and the Eureka team members literally find themselves turning green with envy when they are dosed with gamma radiation. Meanwhile, Allison and Tess are trying to get a clear view of the distant source of a mysterious signal from space. Needing more power for the telescope, they ask Carter and Jo to confiscate all of the Globidium power cells around town. The sites that use the plutonium-like element include Café Diem and the Smart House. Making their rounds, Carter and Jo discover that someone is stealing the radioactive fuel cells. By the time Carter determines that Big Ed is the Globidium thief, there is nothing left of "The Cleaner" but a pool of green goo. It seems that Big Ed had a pet project that grew out of control. 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.

3 "Part Two" August 1, 2006 (2006-08-01)
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 (2006-08-08)
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 (2006-08-15)
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 (2006-08-22)
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 (2006-08-29)
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 (2006-09-05)
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.
