I think I get it. It's something I should have already learned for good. Back home... when I first found out I was the Avatar, the monks made it sound like I'd have to do everything alone. And I hated it. But it wound up not being that way. I couldn't have... stopped the war and saved the world, done everything I could... if it weren't for Katara and Sokka and Zuko and Toph and Suki and everyone else. So... so it'll have to be the same here. And you're right that... we have to work on understanding this world first.
