Recap / Eureka Just Another Day

"This is our home. And this is what I do."

Holly: Oh! Oh! I remember now! You guys are smart, but the Sheriff is the strong force, he holds it all together.
Zoe: He always does.

As Eureka is about to be shut down, the town residents face an uncertain future. Wormholes break out through the town, putting everyone's lives in danger, but a radical solution might cost Jack everything. Meanwhile, Fargo is determined to save Eureka, and finds help in an unexpected place.

Tropes

• An Arm and a Leg: Andy is cut to pieces when he passes through a wormhole after Lowjack; Jo and Taggart find his arm. Andy's reassembled by Zane, while Lowjack is unharmed.
• And the Adventure Continues: Zoe is graduating from Harvard, Jack and Allison are expecting a baby, Eureka has been sold to private billionaire Dr. Grant, Jo continues to be the head of GD security, and her and Zane, who is promoted to head of section 5, finally commit to being in a real relationship, Fargo is working and travelling with Holly, and Henry is the new director of GD. As Zoe and Jack drive down a rainy street, they see themselves, driving into town in the pilot.
  Zoe: Dad... did you just see...?
  Jack: Deal with that tomorrow.
• Babies Ever After: Allison tells Carter she's pregnant.
  Allison: We wouldn't be here without you.
  Carter: As much as I like to complain, there's no place I'd rather be.
  Allison: You sure?
  Carter: Without a doubt.
  Allison: Good, because I really like our baby to be born here. I'm pregnant. You're going to be a daddy again, Jack. Can you handle that?
  Carter: God, I can't wait.
• Back for the Finale: Taggart, Lowjack, Grant and Zoe all return.
• Brick Joke: The final scene has Carter and Zoe leaving Eureka only to pass themselves in the scene shown in the very first episode.
  Carter: Let's deal with that tomorrow.
• Call-Back: For a series finale, this is a given.
  • Lowjack still seems to have the upper hand on Taggart, who still objects to being called a "dog catcher."
  • Jo's proposal to Zane echoes his proposal to her in the other timeline.
  • Henry meets Beverly at the same diner where she met Dr. Grant.
  • Dr. Grant's exit from the town involves cheering, waving crowds, in stark contrast to his previous exit, when he had to sneak away to avoid being sanctioned.
  • Holly remembers "getting wormholed by Doctor Fargo! And I think I liked it."
  • The first plan to get rid of the wormholes leads to them forming one big wormhole.
  • Beverly gets Grace released by trading Senator Wen's location.
  • Zane helps Henry help Grace by recovering the files he deleted.
• Chekhov's Gun:
  • The truck Carter and Zoe passed on the way into town was removing the stabilising device that would have stopped the wormholes (which is presumably why the first wormhole zaps them to the GD lobby straight after).
  • Fargo's strong force watch, which he uses to prevent Jo from removing him from his sit-in protest. Later, Carter picks the words "strong force" out of the Technobabble about the wormhole and realises the watch can be used to get rid of the wormholes.
• Dead Man's Switch: Variation. Fargo's watch can solve the wormhole problem, but only from the other side and it has to be on a person to work.
• Explain, Explain... Oh, Crap!: When Dr. Parrish is wormholed, Allison notices he has skin damage, inconsistent with Carter and Zoe's wormholing. This leads her to realise that the wormholes are joining together, posing a serious danger to anyone passing through them.
• Five-Second Foreshadowing: When Carter, Allison, Henry and Grace are in Café Diem when Vincent tells them "the gentleman outside" has sent them a bottle of wine... vintage 1947. Then Dr. Grant appears in the doorway.
• Flashback: While inside the wormhole, Carter passes through a jumble of images from his time in Eureka.
• Foreshadowing: While trying to stop the closure of Eureka, Fargo is on the phone to someone he calls his "hail Mary." He reminds this person that Eureka "made you who you are," foreshadowing that it's Dr. Grant.
• Insistent Terminology: Taggart is not a "dog catcher," he's a "Biological Containment Specialist."
• Major Injury Underreaction: Downplayed. Carter doesn't seem to be hurt after shutting down the wormhole, but he did fall about a storey and could have spinal damage, which you'd think would warrant more than a "you okay?"
• Naked People Are Funny: Dr. Parrish is wormholed to Café Diem when he tries to enter the GD spa steam room. He drops his towel in front of the entire clientele.
• Negative Space Wedgie: Wormholes start appearing all over Eureka, at first just sending people to random places. Then they start crossing each other, slicing up whatever (or whoever) passes through.
  Carter: Not to interrupt, but WHAT THE HELL JUST HAPPENED?
  Fargo: I think you may have been wormedholed.
  Carter: Wormholes are bad. What did you do?
• Protest by Obstruction: Attempted by Fargo to stop the closure. Other GD employees join in, but calling Grant works better.
  Jo: Fargo, where are you going?
  Fargo: Nowhere. This is an outrage. Somebody needs to take a stand! [Sits on the ground]
  Jo: Fargo, that's kind of the opposite of taking a stand.
• Red Herring:
  • Fargo's strong-force watch doesn't cause the wormholes. In fact, it ends up solving the problem.
  • Dr. Parrish wasn't responsible either, because he's perfectly happy to leave Eureka.
  Dr. Parrish: Sheriff, Ms. Lupo. Are you here to assist me with the move?
  Carter: Actually we are here to see if you are trying to stop it.
  Jo: When it comes to disgruntle employees, you're sort of top of the list.
  Dr. Parrish: Oh, on the contrary. I am fully gruntled. Global Dynamics hasn't appreciated my talents. Now that I am a free agent, the world is my oyster.
• Running Gag:
  • Carter still hates the word "theoretically."
  • While driving Zoe back into Eureka, Carter runs into a wormhole that deposits them straight into the GD lobby where they almost run over Fargo. The Jeep survives, but has to be dismantled.
  Carter: That sounds about right.
• Sequel Hook: A possible example with Holly and Fargo, who are leaving to head up some kind of Darpa travelling team.
• Shout-Out: When Dr. Grant tells everyone he's bought the town, he mentions that there's a condition while looking at Allison. Carter objects with a joke about Indecent Proposal, but Grant just wants Henry to be director.
• Technobabble: Carter gets in on the action.
  Zane: [Henry] wanted to help Grace, so I pulled some information off the data stream so he could check into it. That's it.
  Fargo: Uh, uh, do you mean the quantum teleportation data stream?
  Carter: Wait. Quantum teleportation. That sounds a lot like wormholes, right?
  Zoe: Nice, Dad!
  Carter: Thanks. I pick stuff up.
• That Came Out Wrong: Just as Fargo and Holly have an emotionally touching moment, Carter appears.
  Carter: You need to put your thing in the hole before it blows!
• The Bus Came Back: Grant (now going by Dr. Trent Rockwell) returns to reveal he bought the town.
• Unwitting Instigator of Doom: The wormholes were caused when Zane and Henry tried to recover the files Zane deleted before to help Grace; accessing the database in that way caused an overload, which wouldn't be a problem except that the stabilising device was already shipped out.
