(Flashback to Sasuke's training before the match)
Gaara: Tell me, what is your true purpose? Why do you seek power?
Sasuke: Like it's any business of yours. Beat it. You're interrupting my training.
Gaara: I see it. You have the eyes, eyes that seek power and would do anything to get it, even kill. Eyes full of hate, like mine. We're the same.
