HOPELESS SITUATION
Zuko says to Ty Lee, "It's a bit of a hopeless situation. She can't really do much other than lock herself up and let her demons eat her up. I've tried everything."
Ty Lee blinks back tears and smiles. "You haven't tried me. Or I haven't tried. Whichever of those sounds better. I don't think it's hopeless."
"Why are you helping?"
"Because I love her. I've always loved her and I always will," Ty Lee says. "And love makes you hope and hope, even when you shouldn't."
Zuko does not understand, but he believes her.
Ty Lee marches off to face her fate with Azula.
