[It's obvious that whatever happened here really hurt Suki, but...

Katara still doesn't believe it.]

Right, like he believed it when he said that he was always a girl, or always the Avatar? Or like he believed it when he thought he was a firebender? (She hadn't actually been there for that one, but she'd heard about it.)

Suki... [Katara shakes her head and repeats herself, because she doesn't know what else to say.] There's just no way. I know he loves you.
