My breakdown of the kiss. While saying what Katara said, she was batting her eyelids, and swaying back and forth, if you are giving someone a compliment, you normally wouldn't do that. She flipped her hair after that too. they they kissed. And you forget, he left right exactly after he kissed. She was utterly suprised she was kissed, wouldn't anyone else be too? Then she closed her eyes. She would've not closed her eyes if she hated it. She would have not turned around and stared at him and blushed if she didn't like him. Notice she had her hands were pressed against her too. Since Katara and Aang didn't probably kiss in the cave of two lovers, that was probably her first kiss. I think she loves him, there is no way to deny it...
