Yeah, the mommy issues really came out in this one. Which was a little different from what I'd imagined--I'd thought Katara's anger at Zuko was also tied up in what happened to Aang, and a real fear that it would happen again, and that it would happen again because she let her guard down. That didn't get addressed so much, but judging from her earlier ZOMG AANG YOU'RE ALIVE I'M SO RELIEVED AND NOW SHOWING ABANDONMENT ISSUES stuff at the beginning of the season, I thought it would have been more prominent.
