First off, I know this should be in the Avatar relationship discussion thingy, but I wanted to do it seprately so I wouldn't have to sort through all the other posts on that thread which has 4000+ posts.
I challange you Kataangers to give me at least 3 good reasons why Katara and Aang should get together, and NONE of them can be because Aang has a crush on Katara. If you're planning on saying because of Aunt Woo, I won't accept that because 1. there are a lot of powerful benders in Katara's life and 2. I strongly believe that if the bender was Aang, he wouldn't have overheard. Go!
