After a commercial break, Walter is muttering "Cleveland, Baltimore, Philadelphia" to himself, with Olivia asking if there are any other boxes that haven't been broken into yet. Walter says he doesn't know, because he can't remember why he was putting things into the boxes. "So let me get this straight," says Peter, and I hope by now it's part of the Fringe drinking game that you drink whenever Peter says "let me get this straight" or "just so I'm clear" and the like. Anyway: "You can remember traveling around the country twenty-three years ago, renting all these safety deposit boxes under assumed names, but you can't remember why?" Peter always forgets his dad is mentally ill when it's time to give him hell for something, doesn't he? Walter says whatever it was, it must have been of "profound significance," since he didn't use his usual hiding places. "Well, excellent. That clears it right up," says Peter, who should feel free to shut up any time he likes. Walter, testily, says he was under a lot of stress at the time, which was before the lab assistant was killed in the accident. He sits down on the bed, and takes out a little vial of something that he dumps in the glass of (presumably) water on his bedside table. "I was ... distrustful of everybody. William Bell, your mother. I was convinced I was being followed. Someone was watching my every move." He drinks the water. Peter asks him what medication that was. "My supplements," he says. Olivia asks if he told anyone else, but the answer appears to be no: "I told you I was paranoid," he says already seeming a lot more relaxed. Olivia tells him to get dressed: they're going out.

Over to the federal building, where Charlie, who does an awful lot of work with the Fringe team for a guy who supposedly doesn't have all the clearance, gives Walter a bunch of photographs of banks in the Syracuse area, because in 1985 he gave a lecture there, according to his travel records. "Does any of this trigger anything in your mind?" Walter, kinda giddy, turns around and says, "Yes, but not about banks. Think back twenty years. Imagine yourself then, imagining yourself now, twenty years into the future. In your wildest imagination, could you ever think you'd be here?" Charlie quietly asks Olivia if Walter's stoned. Olivia just tells Charlie to show him the other batch of photos, and to be patient with him: "His mind works in a different way." Charlie watches Walter actually lick the photograph. All Charlie wants is for Walter to not take any sensitive FBI equipment and turn it into a bong, for god's sake.
