Fringe

Peter: Walter. Walter: Peter. You're up early. Peter: Oh, no, I'm still asleep upstairs in my bed. You're just talking to an astral projection of me. Walter: You're just saying that to see if I'm high.

Peter: Who's that at two in the morning? Walter: Oh, my pizza. Peter: So you are high, then. Walter: Maybe a little.

Olivia: I understand that you had a visitor last night. Roscoe: I don't remember talking to him, but I remember that he was here. It's a curse not remembering a miracle.

Peter: Walter, are you all right? Walter: If all right means despondent, yes.

Walter: You know the future. Tell me how I can save my son from dying. The Observer: There are things that I know. But there are things that I do not. Various possible futures are happening simultaneously. I can tell you all of them, but I cannot tell you which one of them will come to pass. Because very action cause ripples. Consequences both obvious and unforeseen. For instance, after I pulled you and Peter from the icy lake, later that summer, Peter caught a firefly. I could not have known he would do that. But because he did, a young girl three miles away would not. And so later that night, she would continue looking, trying to find another one. I could not have know that when she did not come home, her father would go looking for her, driving in the rain. So that when the traffic light turned red, his truck skidded through the intersection at Harvard Yard, killing a pedestrian. Walter: Did that happen? The Observer: You and I have interfered in 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.

Roscoe: I forgot what my son felt like. What he smelled like. How it felt to be around him. But now I remember. Nobody is supposed to have a second chance like that.
