Olivia's Fringemobile heads through Cambridge, with Peter in the shotgun seat, looking like he shouldn't be allowed anywhere near a shotgun right now. Dude is in a mood. Olivia looks at him worriedly, but he just keeps scowling. They drive unawares past Curtis, who reports over his earpiece that they're here. "That's okay," Newton says. "We're done. We've got what we need." As he and the hench-nurse pack up, he pauses to give Walter another injection in his arm from a spring-loaded pistol syringe. "My apologies, Dr. Bishop," he says once again. Walter goes limp, resting his head on the table next to him, his nose all but pressed against the glass jars holding the dying bits of his brain. This episode just keeps finding so many new and interesting ways to make it suck to be Walter, doesn't it?
