Perhaps, says Walter. But he saw a half-starved man and used him, because it suited him, because he was nothing more than an acceptable loss as long as Walter got what he needed. "Is that who I am, Peter? Is that something you can see coming from my mind? From my heart?" Walter whispers that the person who would leave in the middle of the night on his own is a man of hubris and arrogance: "And that's not me, Peter. It's him."

Peter's confused, but Walter explains he's not safe. "It's my mind. Ever since the pieces of my brain were re-implanted, it's been changing... me... back into the man I was before," he says. Blah blah, John Noble great, etc. etc. I mean, it's not anything we haven't really seen before, and there are only so many times I can be moved. It does, however, provide a nice contrast and comparison to where the Bishop boys are going. Each is worried about losing his humanity; in Peter's case, it's tragically literally so. The reassurance Peter gives his father/alterna-father/whatever is touching, though: "I'm not gonna let that happen. We need you. You are our only hope to defeat the Observers," says Peter, adding that he'll be with Walter every step of the way. Walter pleadingly asks for Peter to not let him go, no matter what happens.

Peter strokes Walter's head. "I won't, Dad. I promise." OK, there's me being moved. Hold it for a bit, hold it for a bit -- Peter looks over to Olivia, and they smile at each other, through resignation and pain.

And then the music shifts and it's like "Oh, shit, what now?" And Peter's POV is suddenly electric blue like an Observer's, grids and lines overlaid over a suddenly alien perspective. Peter looks alarmed (and don't think Olivia doesn't notice) but if he's like me, it's because he's thinking, "Oh my god -- my hair."
