Katara wrapped her arms around Aang, and held him close. She'd noticed the fact that he was clingier than usual, and combined with the scarring and the fact that Aang was the only one who was older than the others from home, she knew that something was up, she just didn't know what. She looked up and pressed another kiss to his cheek, just a smidge away from his lips. She wanted to comfort him, and that meant not pressing the issue of things he didn't want to speak of, and not trying to get overly romantic with him. She didn't think it would be all that appropriate, and she wanted to, well, respect him.
