REBADOW: You know, you try to prepare for a death, but always secretly you believe there's a chance that the doctors were wrong, that they'll find a cure, and that as long as he's alive there's time. So, while you think you're stealing yourself, all you're really doing is waiting on the miracle, which is why, when death comes, it's so horrible, because you realize... you weren't prepared at all.
BUSMALIS: But you knew last night.
REBADOW: On some level.
