Speak of the devil, he's with Zoe in his garage lab, talking about their future together. Lucas is worried that Zoe leaving for college will end their relationship. Not to worry, as Zoe thought of a way for them to be together forever: sex! Yes, they can lose their virginity to each other on Lucas's ratty old couch during Zoe's work break. Very romantic. It takes Lucas a while to realize what Zoe is suggesting, but when he does he is ready to make out. They do that for all of two seconds before the garage door suddenly opens to reveal Carter, Henry, and Tess. Poor Carter. His reaction is amazing. He screams "oooh!" while doing a little dance of shock and horror. Henry just looks surprised, while Tess smirks knowingly. Zoe and Lucas jump up and away from each other immediately, with Lucas holding a couch pillow in front of his crotch area. I can't tell what's more embarrassing: taking a chance that your girlfriend's dad will see your erection, or putting pillow in front of it so he can't see it but will know for sure that it's hiding under there. I guess it's not a choice I'll ever have to make, seeing as how I do not have a penis. "And now my perfect day is complete," Carter says, looking at the floor. Well, that's why you should knock. Zoe quickly tells Carter that this was her "idea," like, all he caught you two doing was kissing. No need to clue him in that there was anything more than that going on. Or about to. Henry quickly spots a micro-electromagnetic pulse amplifier in the room, and Lucas says he hasn't gotten it to work "yet." Henry says that's not exactly true. They head outside as Lucas protests that the machine is on stand-by, so there's no way it could be doing anything at all. Henry hands him a pair of special glasses that can see electromagnetic fields, and sure enough, there's something brewing just above the garage. Of course, the weathervane that anyone can see that's spinning around seemingly on its own kind of gave that away, too. Lucas is initially pleased to see some success, then less so when he realizes what this means -- a new magnetic pole right over Eureka.

The group spent the commercial break moving the party to GD, where Carter angrily demands to know how Lucas created a new North Pole. I can't tell which of Lucas's poles Carter is angrier about: the one he created in Eureka that will end everyone's existence, or the one he was about to plant in Zoe. Tess plays good cop and kindly asks Lucas to talk them through his experiment. Lucas says he used Kim's data to create a simulation of the forces Nemesis would create. After measuring the change in gravitational pull this would cause, he tried to build an electromagnetic amplifier that would lock the planet's poles in place so Nemesis couldn't cause them to reverse and thus kill everyone on the planet. Okay, really? Is that the best thing he could come up with as a résumé-builder? It's not like people 2,000 years from now are going to use what will be seriously antiquated technology when the Nemesis thing does happen. They'll have created their own, much better ways to deal with it. Also, they will probably have other planets colonized, so saving the Earth won't be all that important. Lucas says he tested the amplifier out and it failed, so he has no idea why or how it could be causing problems now. Carter is quick to point out that there have been magnetic problems all over town today, one of which almost killed Zoe. Yeah, rub it in, Carter. Nice.
