Azula is his sister. General Iroh came to us for help in rescuing Zuko and Katara from Azula. When were making our escape from Ba Sing Se, Zuko turned on us. We'd just saved him, and he took Azula's side.

You're not the first person to try and get me to talk to Zuko, Wan. Both Toph and Korra have tried. Apparently in a future I haven't lived through things are different, but for me...I'm here while my friends are on the run, hurting, and thinking I'm never coming back. That's hard for even me to forgive.
