Mal: But it ain’t all buttons and charts, little albatross. You know what the first rule of flying is? Well, I suppose you do, since you already know what I’m about to say. 
River: I do. But I like to hear you say it. 
Mal: Love. You can learn all the math in the ‘Verse, but you take a boat in the air that you don’t love, she’ll shake you off just as sure as a turn of the worlds. Love keeps her in the air when she oughta fall down, tells you she’s hurtin’ before she keels. Makes her a home. 


Y’all got on this boat for different reasons, but y’all come to the same place. So now I’m asking more of you than I have before. Maybe all. Sure as I know anything, I know this - they will try again. Maybe on another world, maybe on this very ground swept clean. A year from now, ten? They’ll swing back to the belief that they can make people… better. And I do not hold to that. So no more runnin’.
