Eureka (2006)

In Too Deep - S5-E8

Plot hole: Carter is apparently just learning about Feynman's Day, which Allison explains as "Eureka's version of April Fool's Day." It's highly improbable that Carter could have lived in Eureka for five years and still be oblivious of this, especially given all of the hijinks that happen.

Marshall Jack Carter: Let's not shoot the crazy end-of-the-world machine just yet.

Just Another Day... - S5-E13

Trivia: In the final scene, as Jack and Zoe are heading out of Eureka, they pass their younger selves heading into Eureka. This scene is from the pilot episode where Zoe sees another version of her and her dad. However, in the pilot episode, the other (older) Jack and Zoe are in Jack's original car, not his Jeep, and other Zoe waves at them. I would call this a mistake, but I'm listing it as trivia because I know someone would say "after they came back from 1947, things changed so this changed too."

Try, Try Again - S2-E2

Question: When Jack and Jason go to talk to Todd about MACAA, Todd tells them that they destroyed it in Section 14 pit followed by a nuclear explosion. If it was destroyed, where did the version that is missing from the shelves come from?
