You're blind, dumbass. How long before you go the wrong way and get killed by a bad design decision?

[Even if he didn't realize the blindness at first, of course he's going to leap on it now. And it does make a kind of sense in retrospect. Sam was blinded by the nuclear attack.]

Besides, I'd say me saving you from an untimely death is a lot better than the way I could be acting after that first meeting. Gimme your hand. We're going to buddy system this shit, and I don't have footsteps for you to follow.
