Zutara. Period.

Zutara must prevail. Now, in the show (A:TLA) Katara may end the final season with a kiss for Aang, but I'm sure that what they don't show you is that a week later, for his "Tiniest spider-fly must live" thing, she broke up with him. I mean, like, dumped him haaard. She then found out how hot Zuko was with his angsty no-pony tail wonderfulness. Plus, there was this dude at the A:TLA premiere that I went to who had a red and purple scar (which made him look totally goooood lookin' ;) who was awesome and wicked and well... Awesome. Which thereby proves that all Zukos in all universes are hot. And shmexy. And, well... Katara is perfect. Urgh. Together, they make a totally angsty, shmexy, hot and perfect. Die, Kataang! Jump off a cliff! Zutara for the win! This, is, Zutaraaaaaa!
