Lucas again protests that his amplifier isn't even turned on, nor does it have the power needed to make this stuff happen in the first place, so it can't possibly be responsible. Henry says it could have been assisted by an energy boost from another source, just as Tess says there was an energy boost when the supercollider exploded. So the amplifier threw off the magnetic stabilizers in the supercollider, which then caused the explosion, which then boosted the amplifier's power and created a loop of building energy that formed a new North Pole over Lucas's garage. Whoops! Lucas is very sorry about all of this. Carter angrily tells Lucas that it will be his responsibility to tell Santa that he has to move his workshop. That sucks for Santa -- I hope he's ready to watch his elves turn into piles of smoking ash after various and multiple mishaps. "Lucas, what were you thinking?" Zoe asks. Lucas says he "couldn't handle" the thought of Zoe leaving town without him, so he tried to "solve" Nemesis in the hopes that it would get him a recommendation to MIT from Henry just like the one he gave to Zoe. Yes, Henry was the mystery recommendation writer, of course. Sorry, Tesla students who didn't get early admission to Harvard even though their GPAs are better than Zoe's! The trick was to make your dad be best friends with the town mechanic/super-genius. Carter's rage switches from Lucas to Henry, who stammers out an apology for not letting him know earlier. Henry has secretly hated Carter since the end of Season 1, and now, at long last, he's gotten his revenge.
