And they go for a stroll on campus grounds, amid the fallen leaves and golden light of fall. "You call it... autumn. Is that right? Lovely word," says the Observer. This guy can catch bullets but he's still not clear on the names of the seasons? I'm not too impressed with a guy who could be bested by my daughter if she got some favourable categories on Are You Smarter Than a Preschooler?.
Walter doesn't have time for the small talk, and he wants to know what the Observer knows about Peter and the doomsday device, and how he can save Peter from dying. The Observer obliquely says that there are various possible futures happening simultaneously, and he can tell Walter all of them but he cannot tell Walter which one will come to pass, and then he outlines a butterfly-effect scenario for Walter (i.e. a real one, not the way it happens in that horrible Ashton Kutcher movie which manages to get it completely wrong EVEN THOUGH THEY NAMED THE MOVIE AFTER IT): what if after the Observer pulled Peter out of the lake, that later that year he caught a firefly, the same one that would have been caught by a little girl, except she didn't get that one so she stayed out later that night looking for one, prompting her father to go out looking for her, driving in the rain, skidding through an intersection at Harvard Yard, killing a pedestrian. Walter's all HOLY SHIT DID THAT HAPPEN, and the Observer simply says, "You and I have interfered with the natural course of events. We have upset the balance in ways I could not have predicted. Which is why now I need your help." Walter wants to know what he means, and the Observer "explains," which is not exactly the right word for it, "When the time comes, give him the keys and save the girl." Walter, understandably, has no idea what this means, and asks for an explanation. The Observer says, "You should answer your phone" only he says it before the phone actually rings.
Walter answers it, and it's Peter: "Apparently your friend is fighting crimes now," and he explains that the Observer (who, as Walter turns, has naturally disappeared from sight) foiled a robbery at a jewelry store: "Three guys came in, killed the owner, tied up the girl who worked there." Walter's all, "Girl?" like yes, Walter, females make up about half the population of the world. When Walter finds out the Observer saved her life, he insists on speaking to her. Peter says he'll have to wait, because the cops are about to take her downtown so she can give a statement, and Peter demands that Victoria Dimiro be brought to him after she's finished with the cops. You know, the last few lines of dialogue could have been used in any movie featuring a pimp.
