Then a phone starts ringing. Not the trill of a cellphone or the electronic tones of those phones in the old CTU on 24, but an old-time brrrring-brrringgg clang of a black phone mounted on the wall. You'd think it was a teletype suddenly coming to life from the way everyone reacts, other than Walter, who marvels that he hasn't heard that sound in ages. Astrid says the number must still be in Harvard's directory.
Peter answers it all cheerful, and then instantly looks all grouchy when he says "There's no one here by that name," and then says that's he's sure, and hangs up. So I'm not sure why he thinks anyone ought to believe him when he says it was a student looking for financial aid, and from the look on Astrid's face, she clearly doesn't believe him.
Anyway, Peter just starts unhooking a hard drive, saying he's got a guy he thinks can help. Olivia asks who. "You really want to know?" "Good point," says Olivia. No, the correct answer is "yes." I mean, this is a unit that speaks to DEAD PEOPLE for god's sake. I'm sure Olivia can handle a slightly shady associate. Anyway, Olivia lamely tells Peter to be careful with the hard drive because it's evidence, and he flips it over his shoulder. Yeah, this is going to go well.
Olivia tells Astrid that she's going to go talk to Greg's friend Luke Dempsey (again), but Astrid stops her by saying she thinks she knows who was on the phone. She pulls a piece of paper out of her pocket and gives it to Olivia, who reads it, and then looks at her.
Peter strolls across the street to the old-school style of the Fort Knox Five. Sweet. Walk a little longer, Peter! Anyway, I take it by the hip-hop that we are supposed to know that we are in the gritty streetwise part of town. He walks into what appears to be some kind of computer or electronics shop and greets "Akim," who's fiddling with some machinery on the counter. "Peter Bishop. Long time. Not long enough," says Akim.
Peter flashes some kind of ... I don't know, gold doubloon? Akim's eyes go wide. "I can't believe you kept it," he says, adding he could have sold it for a fortune, and Peter, rolling the coin along his knuckles, says he kept it to remind him not to gamble more than ... no, wait. Always gamble more than ... no, that's not it. Some platitude about gambling, anyway. Akim says, "I can have it back?" and Peter says "sure" and goes to put the coin in Akim's palm, but he's made it disappear and then he pulls it out of his sleeve, like maybe he thinks Akim is six years old or something.
