Back on Earth-1, Olivia has tracked down Sam Weiss's apartment -- well, the landlord knew him as "Seamus Wiles," which didn't make as much sense to him as "Sam Weiss" does, he tells Olivia, as he lets her into the apartment. He wants to know what Sam did, but Olivia says she just wants to ask him a few questions. "So long as there's no dead bodies in there," says that landlord. Note that Olivia wisely doesn't promise anything she can't deliver.
Inside, the apartment is almost completely barren, apart from some papers and a bottle of Brut -- really? -- on the fireplace mantle. Sam's departure seems to have come as a surprise to the landlord. "Last guy who bailed on the apartment ended up being a hoarder. Took me three weeks to clear out the trash," he says. Arguably, if he left all that stuff behind, he wasn't a very good hoarder.
Over at the doomsday warehouse, Peter sits looking at a computer screen in a room full of monitoring equipment, and he contemplates the plastic bag that contains some sort of clothing. Probably trying to remember if he returned the Little Fockers DVD to Blockbuster.
Elsewhere, Broyles asks Walter if he really thinks Peter could turn off the machine. An anxious Walter says the machine's emitting an energy signature like an electric current: "Peter thinks that because of his relationship with the machine, that if he goes into it, the current will run through him, creating a kind of a closed circuit. And if he can complete the circuit, then he can also break it or turn it off," he says. But Broyles wants to know what Walter thinks as a father, if he thinks it's a good idea. Man, you want to know a father's perspective on what's safe for his kid? I don't think it's a good idea for my daughter to date while I'm still alive! I'm a terrible judge! But Walter bravely says that it's because of his selfish inability to let his son go 26 years ago that this is happening, so his opinion as a father doesn't matter.
Broyles says it matters to him, so a very scared Walter tells him that he honestly doesn't know what's going to happen: "The current of energy is so powerful. It's unlike anything I've ever seen. And the thought of what that could do to my son... I don't want him to suffer." Broyles comfortingly puts his hand on Walter's shoulder.
Well, at least Peter gets to wear a kickass black jumpsuit! He's in the main area, with the device humming nearby, zipping up. Astrid asks if he's sure he doesn't want her to call Olivia. "If it doesn't work, she's gonna find out soon enough," says Peter, which kind of misses the point. He thinks better of that, and he starts to give Astrid a message to tell Olivia, and Astrid, blinking back tears herself, trots out the hoary old action movie cliché: "You'll tell her yourself," she says. Look, if we're going to use classic overused movie lines, why the hell has nobody said, "That's so crazy it just might work" yet?
