I guess no one thinks the doomsday machine is an imminent threat or anything, because they've decided to go get bombed at a bar, with Fauxlivia marveling that they've been back for two days, and Walter's already driving him to drink. Then they joke about Peter being stuck in one of those bad buddy cop movies, handcuffed to a mad scientist who kidnapped him from another universe, and then Fauxlivia says she thinks Broyles is right, that they need to figure out what the thing does, and they can't do that without Walter.
Peter's only response is to get another drink, and then "Crazy" by Patsy Cline starts playing and Fauxlivia says she loves this song, and Peter's surprised because as long as he's known her, he's never heard her express an interest in music, which is actually kind of strange because we've seen Olivia listen to some fairly trendy stuff at her place. Anyway, she says she's been noticing a lot of things since they've been back. "I guess being over there and meeting another Olivia Dunham has made me think about the way I look at the world, the choices I've made," she says, and thankfully she doesn't mention how much she wants to have sex with Bono, and then she gets up to dance and goads him to dance with her, so she puts her arms around his shoulders while he holds on to her waist (and her gun) and then Peter says, "I guess there's nothing like seeing another version of yourself to give you a little perspective," whatever that's supposed to mean, and then he says it was strange, being with the other Fauxlivia, because there's nothing women love hearing from their boyfriends more than about when they were with other women. "It was like looking into one of those carnival mirrors," he says, and I guess he's talking about those carnival mirrors where you look exactly the same but your hair is red.
Fauxlivia teasingly asks him if he doesn't like red hair, and he says he's always preferred blondes: "But you did make a very sexy redhead," he says which she thinks is "good," and at some point Peter's probably going to be considering the possibility of getting the two of them together, but he just says that the more he thinks about being over there, the less real it seems. "But you, you still feel real," he says. And then her phone rings.
