Leo: All right, let's just take a deep breath here. We can talk this out.
Kyle: I don't want to hurt her, but I will if I have to. Your kind is responsible for a nightmare that won't go away, for all those nights waking up in a sweat begging that the flashbacks were just a dream.
Piper: Kyle, please.
Kyle: It's not a dream, though, is it, Leo? You Avatars are as real as the air that we breathe and just as vacant. My parents were viciously murdered by them. So if I were you Leo, I'd do what I say.
Leo: The Avatars couldn't have killed your parents, Kyle. They believe in peace.
Kyle: I'm gonna give you three seconds to summon one of your buddies here so I can kill them. If you don't, I'm gonna kill you.
Leo: I can't do that.
Leo: Avatars aren't the enemy, Kyle.
