Lord i can actually relate something real life to that. My best friend is dating a guy who is younger and he is like infatuated with her, and just like kinda likes him. O.k. My zutara defense. Let me start off by saying i'm not some sort of crazy fanfiction fan person thing. I'm a writer. And from a writer's stand point, Katara's character shouldn't have been what it was. ITS A KIDS SHOW I KNOW. But she has been betrayed all her life, she was family-less, improsined, almost killed, starving, and exposed to alot of death and war at all a very young. During that one episode when she went to go get her revenge against the man who killed her mother, her character go dark and devolved and it should have stayed dark! The pressure of being mature and maternal-like all the time should have broken her down, which meant it would make sense for her to reach out to someone she can't trust as sort of a lust/desperation thing.
