Well, there is more to it than that: Walter thinks the Observer wants Walter's help to undo the damage he's done: "But I can't do it. Don't you see? Doing that, I would lose him all over again," says Walter. "Lose who?" says Astrid. Jesus, Astrid, try to keep up. You're a linguistics expert, presumably including English. "Peter!" says Walter, and he rushes off to the phone.
Meanwhile, Peter and Olivia aren't so much bringing Victoria back as they're following the police car that's transporting her. Peter's phone rings. It's Walter, wanting Peter to ask Victoria where she was in 1985. Being born? Just kidding. "Twenty-five years ago? I remember staying out late to look for a firefly..." Actually, Peter tells Walter that Victoria's in the car in front of them, and they're about five minutes away. He doesn't get much more out before the police car is broadsided by a pickup truck -- the one stolen by the Observer. Is it racist to point out that Observers can't drive? Olivia swerves to avoid the accident, and blows a tire as she hits the curb and stops.
Peter and Olivia get out, as the Observer gets out the truck. He glances at Peter and Olivia, then runs off, Olivia in pursuit. She yells at Peter to check the other car, and Peter STILL hasn't hung up the phone on his dad, despite all the hullabaloo, and he fills Walter in on what's happening.
Making it to the police cruiser, Peter tells the injured officers to get on the dispatch and call an ambulance, which is something I'm sure the bleeding men didn't think of. He tells his dad he's got to go, and starts to tend to the hyperventilating Victoria. He can't find her inhaler in her purse, and she gasps that the bald man in the store took it.
While Olivia weaves her way through the slack-jawed yokels on the street, Peter carries Victoria over to the rear hatch of his car. And then despite the fact that they were five minutes away when the accident happened, Walter manages to pull right up a MINUTE after the accident, which happened in the middle of an intersection, stopping traffic in all directions.
Walter's relieved to find out that Peter's all right, and Peter fills him in on Victoria's asthma, which was triggered by her elevated heart rate in the accident. Peter tells him there's an ambulance on the way. Yeah, too bad it's not driven by Walter, or it would have arrived thirty seconds ago. Peter says he's going to go after Olivia and the Observer: "Give the keys and save the girl," he tells Walter, who's stunned to hear the words that the Observer told him: "This is it. This is his plan. This is what he wanted," says Walter, fretfully, explaining to Peter that the Observer is course-correcting. "I don't know how, but he's done some kind of a chain-reaction that started from the moment that we walked into that nursing home to meet Roscoe," says Walter, adding that if he saves this woman and lets Peter go, then Peter will die, and then he turns into an Italian widow, wailing about Peter being taken away from him.
