"Throw a group of enemies into the vilest prison together, and they will form a bond stronger than you can imagine. Offer the slightest glimpse of escape, however, and they will tear each other apart scrambling to the exit."
-Teridax (It's the general gist of the quote, not the exact wording)
"As strong as you may think you are, I am stronger."
"I will have plenty of time, once I have destroyed you."
"I don't have any friends, only enemies I haven't killed yet."
"Me too, buddy, me too!"
