Anyway, Walter's not too giddy from the excitement of welcoming her to the family that he can't yell at a delivery guy for rattling fragile equipment too carelessly, and then a box slides off a counter but instead of hitting the ground, it floats a few inches above it, much to the surprise of the delivery guy.

The box is then set down gently. "Was that you?" Walter asks Olivia, and she says she learned to control it a few years ago. "I'm impressed," says Walter. I should think so!

Elsewhere, in a park clearly chosen for the fact none of the path lights seem to work at all, Moreau meets up with Walternate, who tells him the next target is the wormhole in Central Park. "Considering your world was destroyed by a wormhole, I suppose it's fitting," says Moreau. Actually, we're not seeing Walternate's face yet because for some reason this scene is doing a "Who's he talking to?" reveal, even though we can a) hear his voice and b) who ELSE is it going to be? Moreau's got a much bigger electralite, which he tells Walternate followed his specifications to the letter, and will yield more than twice what the device did last night. "It won't be long ... 'til this world joins mine," says Walternate. We finally see him. His hair has been painted white. Because he's older now, and there's only so much craggier the makeup artist can make John Noble look.

After the commercial break, Peter strolls into the Harvard lab, where Walter is hard at work (under guard), and slaps down a bag of Red Vines for his dad, who is having no luck making any sense of the electralight. "I'll continue to run diagnostics on the canister, but even if I am successful, our world is still ending," he says, and then fills in the backstory for us (not for Peter, who would know all this), that their destiny was set the day they triggered the machine. "I didn't understand until it was too late that our two worlds were inextricably linked. Without one, the other simply cannot exist. When their world was destroyed, that was the day we sealed our fate. For all intents and purposes, that was the day we died," he says. Ladies and gentlemen, we have a title!
