[Sokka squints at Aang, waiting for the punchline. When one doesn't come, Sokka shakes his head and rolls his eyes.]

That's a stupid promise, Aang. Why would you even agree to that? Why would Zuko even ask you to? I couldn't even get you to kill Melon Lord, much less Ozai. And then you agree to kill Zuko?

[He just. Sighs.]

Did I go along with this? Because that's crazy. Dumb and crazy. Why would Zuko even become like his dad? [A beat.] Is that why this whole almost war thing happens?
