how do 당신 think zuko would have reacted, if he had seen katara in book 2 chapter 19?

Who know's maybe after all that happend Zatara could have happend.(you never know)

Maybe he would have started to hunt the Avatar.. again, but knowing his uncle, Iroh would have tried to stop zuko.. just was bored XD

He'd be like : "Would 당신 like some tea???"
and she would have ran away the same way...

maybe stunned. and katara would run away.
and he will just let her go

he would have been stunned. he would be gaping at her. she would run and he would drop the 차 and go after her. he would try to tell her he has changed.

He suprised and be happy.

hmmm he would probable be shocked at first, then nervous.

He would as if she wanted tea,then plead for her to listen to his explanation.

he would explain to her that he and his uncle have started a new life, away from politics and war,that he has changed.

Katara would either tell her group, 또는 investigate zuko even closer

but eventually I could see Zutara coming together :)
