Roy: Quite an experience to live in fear, isn't it? That's what it is to be a slave. I've seen things you people wouldn't believe. Attack ships on fire off the shoulder of Orion. I watched C-beams glitter in the darkness at Tan Hauser Gate. All those moments will be lost in time like tears in rain. Time to die.

Deckard: I don't know why he saved my life. Maybe in those last moments he loved life more than he ever had before. Not just his life, anybody's life, my life. All he'd wanted were the same answers the rest of us want. Where did I come from? Where am I going?  How long have I got? All I could do was sit there and watch him die.
