"The Observer? It's been a while since we've seen him," says Olivia. Yeah, well, sometimes he's really easy to spot, and other times you really have to get lucky to see him, but if you look he's always in there somewhere, and I'm sure there are websites that will tell you exactly where to look... but I digress.
Anyway, Pam the nurse leads the Fringe gang down the hallway -- Walter takes a little longer to follow because he's staring contemplatively at the photo of Bobby and the Observer.
As the Fringe gang and Pam enter the rec room, she tells them that when she took a second look at the video, she recognized the boy is Bobby, thanks to the photo that Mr. Joyce keeps on his bedside table. Pam points out Mr. Joyce in the rec room. He's sitting in an easy chair, wearing a vest with no shirt on underneath, looking like he's not entirely aware of his surroundings.
Walter gets rapturous. "Roscoe Joyce!" he says, surprising Broyles, and Peter asks if Broyles has ever heard of Violet Sedan Chair, which is suddenly Walter's favourite band even though he's never once mentioned them despite constantly listening to music on this show, and I was going to say that "Violet Sedan Chair" is an aggressively stupid band name, but then again we live in a universe that includes the likes of Cherry Poppin' Daddies, Puddle of Mudd and Hoobastank. Anyway, Roscoe Joyce here is the keyboardist: "He's a hero of Walter's. He's up there with Einstein and Tesla," says Peter, presumably (I hope) referring to Nikola Tesla and not the band Tesla, or maybe he is referring to Tesla the band, in which case the missing parts of his brain may be even more tragic than we realize.
Walter has introduced himself to Roscoe, and Olivia follows suit, and gets right to it, asking about the visitor. Roscoe shows her the picture of his son and says he doesn't remember talking to him, but he remembers his son was there. "It's a curse, not... remembering a miracle. It was a miracle seeing him again. Can you imagine what that's like?" No, I don't believe that any- "Yes, I can," says Walter, quietly. Oh, right, he knows exactly what that's like. Is every case from now on going to reflect the turbulent personal lives and regrets of the Fringe gang? And then Roscoe zones out, looking at the photograph, and Pam says it's time for his physical therapy and medication.
