Olivia gets off the phone to tell Peter that the Observer's been spotted in Brookline. Peter hesitates, though, wanting to make sure his father's all right. "If 'all right' means despondent, yes," says Walter. You know very well it doesn't! Astrid tells Peter that she'll look after Walter, so Peter and Olivia take off, with Olivia McDistracting Ringerson apologizing again.
After they leave, Roscoe remembers that his son was wearing a brown shirt that his mother gave him. "He told me I would meet you... Walter... Bishop. He called you by name. Bobby said I was supposed to... help you," says Roscoe, who is really going to have to pick up the pace if we're going to finish this episode on time. Walter asks how Roscoe is supposed to help him. "I don't know. Don't you?" asks Roscoe.
In Cambridge, The Observer is standing on a city sidewalk, and he's joined by December. Good thing these odd-looking fellows who dress exactly alike try to avoid attention, hey? The Observer tells him he has set everything in motion, but December says he's watched Dr. Bishop for just as long as he has: "Perhaps not as closely, but I think you're wrong. He won't do it." The Observer disagrees, saying that he thinks Walter has changed. They watch as a guy parks his truck and locks it, then walks away. December registers his disagreement again, and says they'll find out soon enough. The Observer strolls over to the freshly parked pickup truck, presses his finger up against the keyhole, and then gets in and simply drives off, without setting off any kind of alarm.
Back in the lab, Roscoe Joyce is playing a much more jaunty number, but they still haven't figured out what Roscoe was supposed to do to help Walter, who is at least enjoying the music. "Just hearing you play, I feel like I'm a teenager again," he says, and then he asks why Violet Sedan Chair broke up. Roscoe shrugs and chalks it up to creative differences. They decided to take a break and give the band a chance to regroup, but a couple of years away from the keyboard turned into a couple more, and a couple more. "Eventually, it just seemed easier not to. I suppose that's hard to understand," says Roscoe, and Walter is all, "No, as usual, it parallels exactly some personal situation of mine."
