If guys like us didn't get second chances, I wouldn't be alive.

[Might as well lay that one right out, because it's true - Wash is only here because of an act of mercy in the right time and place. That fact is engraved on his bones at this point, and he's not exactly shy about it.]

[He's also been where York has been, or at least in a similar place - expecting death, and instead given a place to recover. The thing is, once you recover, you can't just stop - if you do, what's the point of living?]

So, what? You get your basic human needs fulfilled and then you give up? You looked at something you both wanted and decided it would be too much because you already have a roof over your head and that's enough?

You're allowed to be grateful and still want more!
