After a commercial break, Peter comes strolling into the lab with the econo-size carton of the "tin foil" like maybe he traveled back in time to get tin foil instead of aluminum foil. No root beer float, I see. He finds Astrid slumped on the floor, and he rouses her, asking her where Walter is.

Henry Jacobson is also being asked some questions, but he's doing it while strapped to a chair with wires attached to his forehead and up his nose, hooked up to an ominous machine, while Mr. Scowly asks him questions about the vibrator and who it was who came to see him. "She's come to you now. Think about that woman," he says. Henry's much too freaked out to respond, and Mr. Scowly cranks a dial on his machine, which sends Henry into paroxysms of pain. He orders Henry again to think about her, and then appears to be listening (he's got a headphone tucked into an ear). "See? That was easy," he tells Henry. Scowly then picks up his light-gun and fires it, perhaps at Henry?

Walter's in what could be the same diner he and Peter visited in the last episode; he's finally getting a root beer float. He starts sucking it back enthusiastically, when who should arrive but Baldy. Walter does not look in the least surprised. They chat about the glories of root beer floats, with Walter offering Baldy a bite. He declines, saying, "I wouldn't taste much anyway." So try a root beer float with eleven jalapenos! After a little more small talk, Baldy thanks Walter for hiding the beacon. "I know you have questions. Soon you will have answers," he says. Walter looks like he doesn't want answers so much as another root beer float.

Back at the Harvard lab, Charlie has shown up to co-ordinate the search for Walter, while Broyles yells at Peter, who's not shy about yelling back, about whether Peter has any idea where Walter went. It's a moot point anyway, since Olivia's alerted that Walter was picked up wandering down the median of I-95.

Walter's in a prisoner's jumpsuit, and not happy about it, when Olivia and Peter come to question him. He's actually quite co-operative, short of actually telling them anything about the cylinder other than that someone's coming for it, which is why he had to hide it. He says he doesn't remember where he hid it, or from whom. Olivia, talking to Walter like he's a child, says they need to find it so they can keep people safe. He won't tell Olivia what the cylinder is, but he figures he only has to keep it hidden for about four hours, and this is a theory he's discussed with a friend. Peter makes a Harvey reference, which is sure to make the kids go crazy.
