He wanders the aisles, looking at the classic games -- a vintage Battlestar Galactica game by Parker Bros., a display of Rubik's Cubes (told you to remember it!) in what looks to me like their original packaging. Damn, I loved those things. I had the Rubik's Snake, the Rubik's Sphere, Alexander's Star, a pyramid one... Couldn't solve any of 'em! Well, except the Snake. That one was easy. Peter picks up a Cube and examines it, while Elizabeth watches.

They stroll over to where a kid is playing OH MY GOD HE'S PLAYING JOUST I WANT TO BE TEN YEARS OLD AGAIN and Elizabeth is all overly interested, "Ooh, that's a strange game. What's that called?" and the kid tells her, and Elizabeth looks at Peter, and he's not so smiley any more. Listen, Peter, I have to tell you: your mom is hot. Like seriously smoking-beauty hot. I mean, I realize she's not really your mom, but your actual mom looks exactly like her, so let's not split hairs. Just want to tell you now. In a couple of years your friends are all going to start thinking so too.

Peter wanders over to look at the airplanes, making whooshing airplane noises as he flies them around, and then smiles at his "mom," who smiles back. So: Olivia of Earth-1, struck by the zeppelins of Earth-2. Peter of Earth-2, struck by Earth-1's planes.

Over at the daycare, Walter tells Ashley that he suspects Olivia's crossing-over was triggered by an extreme emotional response. "Her black eye," says Ashley. Clearly, Walter demands only geniuses for assistants. "So now we need to design a series of experiments around emotional flexibility," he says, but before they can get too far into this, Elizabeth strolls in with Peter, saying she wanted to show Peter where Walter works.

Walter gets all excited and starts yammering on about Peter's plane, but Peter has already spotted Olivia, and the two of them are busy smiling at each other, until Walter finally notices. "Aha. The beguiling Olivia Dunham beguiles," he says, which ISN'T CREEPY AT ALL OR ANYTHING, and then Ashley pulls Peter away to go for a snack, and when the two of them go, Walter tells Elizabeth that he thinks Olivia may have crossed over: "And if I'm right and she has..." he starts, and Elizabeth finishes for him: "... then she can take Peter home." She hugs him, saying she knew he'd find a way. He warns her that he still has to work out how she does it. "But we're nearly there," he says. Hug now, sex later, then.

Oh, my childhood is really on trial here now, with the Betamax tape that Walter loads into the video camera. Good god, we had a Betamax. And since it was a Sony, it lasted for-fucking-ever, and my parents refused to buy a new VCR until the old one conked out, and I swear to god we still had it into the '90s when you couldn't even rent anything for it but it still worked to record shows, and for all I know my parents would STILL be using it if my mom didn't happen to win a draw at a drugstore for a new VHS. Where was I? Oh yeah, San Dimas High School football rules!
