Kataang after the hundred year war

Zuko comes back

Zuko comes to Kyoshi island to find katara and bring her back because things did not workout with him and mai
Zuko- I have come to take you back katara let's go
Katara- I am not going I am happy and I love aang
Aang- why do you have to take her can't you see we are happy
Zuko- aang I love her more than you and I can take care of her better then you
Saying those words to aang made him go into the avatar state and him and zuko started fight then zuko shot him with fire and it hit aang where Azula hit him with lightning and when zuko did that aang fell down and remained motionless.
Then sokka and suki came out of their tent to help him and katara almost drowned zuko fighting him and crying and yelling at him calling him a monster and a murderer that she should have never trusted him. 
Hearing this made zuko tear bend. And full on cry and regret what he did and then katara drowned him. But he lived (yay).
