“You're awfully dark, brother," he said. "You don't know how dark.”

“I don't care what you think. You're not my brother," Clary said. "You're a murderer."
"I really don't see how those things cancel each other out," said Sebastian.”

“Damn it," I said. "I don't suppose you have any ideas on how to kill Littleton."

He smiled at me, his teeth very white in the darkness of his face. "Eat him," he said.”

“And you don't care that I'm your brother," he said. "I know how you felt about Jace, even when you thought he was your brother. You can't lie to me."

"Jace is better than you."

"No one's better than me.”

“If you're going into a very dark place, then you should take a bright light, and shine it on everything. If you don't want to see, why in God's name would you dare the dark at all?”

“Drew Barrymore: Eddie Vedder said something like, "The more you're known as a personality, the less you're accepted as an entertainer."
Edward Norton: I would agree with that. On the other hand, I hate the "dark prince" act that some actors put on when they're doing publicity. If it's for real, if you're really a dark prince, then don't sit down with an interviewer and act like a dark prince. I don't necessarily love doing these things, but once you've agreed to do them, I think you ought to get on board.”

“Must be awfully lucky to see colors like that. I bet they don't even know how lucky they are.”

“Until we have seen someone's darkness, we don't really know who they are. Until we have forgiven someone's darkness, we don't really know what love is.”

“You've changed," he said. "You're-uh-"
"Yes?"
"Taller."
"I hope so. I was ten the last time you saw me."
"And your hair's really dark now-and short," he added.”

“It's simple, really," Alaric Wulf said. " Lucien Antonescu is the prince of darkness."

Jon nodded. "Yeah," he said. "We know. He's got a castle and stuff.”
