“I don't know. A proof is a proof. What kind of a proof? It's a proof. A proof is a proof, and when you have a good proof, it's because it's proven.”

“In case you didn't know, dead people don't bleed. If you can bleed-see it, feel it-then you know you're alive. It's irrefutable, undeniable proof. Sometimes I just need a little reminder.”
“You don't always need to know your destination when you set out on a journey.”
“Everybody always knows something," said Adam, "even if it's something they don't know they know.”
