Olivia finds Astrid and Walter working away in one of Massive Dynamic's spare labs while sporting jaunty tinfoil hats. "Okay, we know where Tyler's going," she says. "Please tell me you've got something better to stop him with than...what you're wearing." I do so enjoy some of Anna Torv's off-kilter line readings. Walter whispers to Olivia that he's merely worried that their hosts are trying to read his thoughts. "Massive Dynamic gives me the creeps, too," agrees Astrid, who should probably know better but whose hat is at least better constructed than Walter's. Olivia struggles to follow along as Walter explains that the pilots in the test program were found to be "highly responsive to magnetic fields," so they're making a pulse generator. "We're going to crash his brain," Astrid translates. Walter says Tyler will go completely blank for a few seconds. "He may even vomit." "Which, hopefully will give you the window you need to take him down," Astrid says. But then what? Once he's back up, they'll be in the presence of a teen sociopath who can once again control their every movement, but I guess they'll worry about that later, because Olivia says, "Okay, let's pack it up. We're leaving." So, hope you're done.

Big floaty letters reading simply "Springfield" over a suburban house could only be more of a Simpsons shout-out if the place were pink (it's not). A woman works in the garden out front when Peter and Tyler wander up and the latter says, "Renee Davies?" She's all friendly and helpful, until he tells her who he is and she goes kind of blank. "Oh my God," she blurts, and he rushes into her arms. Clearly not knowing where to start, Renee asks him who Peter is, and Peter's only answer is, "Mind if we go inside?" Hello, Mind, nice to meet you.

Once that's been accomplished, Tyler sits across from his mom saying he blames not her, but his father for not wanting them to be together. She tries to straighten him out, but he's not hearing it, saying the two of them can leave now. She just barely manages to avoid laughing in his face. Just then a poor man's Greg Grunberg walks in, and Tyler's like, "Who the hell's this?" Obviously it's Renee's current hubby, Seth, so Peter suggests to Tyler that maybe it's time to go. "I think I see who's the problem here," Tyler spits at Seth, because he's an idiot. Then he casts his attention over to Peter, who unwillingly stands up, fishes the cop's gun out of Tyler's messenger bag, and points it at Seth. "Tyler, what are you doing?" Peter grunts helplessly. Yes, be sure and pin this on the kid for the benefit of the victims. That'll work.
