Derek... [Katara frowns. This is not a frown of concentration. It's one of concern.] I might need to get back to you on that one. I haven't spoken to him in a while. He's been... fighting an illness... which has made him not like himself. But it's easy to tell if he's better or not. If he's talking, around people... then someone helped him.

[Like he wouldn't let me help him.]

...if he's not, then he's dangerous to himself and other people. But the man I knew, before he got... sick. Was a very good man. He helped train Sokka for months, he picked out the light weights I run with. He was a hunter and a warrior and someone to be trusted.
