"You make a fine octopus, Pupil Aang."

"(gazing at Zuko with a dark look) You might have everyone else buying your... "transformation", but you and I both know you've struggled with doing the right thing in the past. So let me tell you something right now. You make one step backward, one slip up, give me one reason to think you might hurt Aang, and you won't have to worry about your destiny anymore. Because I'll make sure your destiny ends, right then and there. Permanently. (exits the room, leaving Zuko shocked)"

"In the avatar state... You're at your most powerful, but you're also...at your most vulnerable. If you're killed in the avatar state, the reincarnation cycle will be broken and the avatar will cease to exist."

"(to himself, after revealing to Aang that he was the one who sent Combustion Man) Ugh, why do I have to be so stupid? How could I tell them that I sent an assassin after them? Couldn't I say that Azula did it? They would've believed that! Stupid! (Hits his head)"
