Yes or no
Aang would be extremely hurt, because he trusts Zuko and Katara, and he and Katara are kind of dating.
No. Katara marries Aang. And Zuko marries Mei. I personally go for Zutara and wished that she did though.
he would probably start cussing in another language
Only as a friend, the thing that Zuko and Katara are in love is total fanfiction, Zuko loves Mai and Katara loves Aang.
no zuko and katara never go out zuko ends up with mai and katara ends up with aang
Not really, but in the episode 'The Ember Island Players' the actors portray that Zuko and Katara had something in a cave, and Aang gets really mad. This, of course, does not happen.
Zutara (Zuko X Katara) is a fanon pairing, meaning it does not occur in the series. So, no. Katara and Aang eventually get married and have a son, Tenzin.
yes you can use fire with zuko and aang only near the end,earth with aang and toph,water with aang and katara,and air with aang yes you can use fire with zuko and aang only near the end,earth with aang and toph,water with aang and katara,and air with aang
No way, they have totally different personalities, Zuko loves Mai and Katara loves Aang, that concludes the argument!
It is never made clear whether or not Katara develops a crush for Zuko, but at the end of the series, we are certain that she and Aang are together.
Towards the end she starts to like aang (watch last episode)
No, it's against the law for a Waterbender to love a Firebender, and besides, Zuko and Mai are perfect for each other and so are Aang and Katara!
