Hello, Brother
"Iroh."
"Ozai."
Iroh stroked his beard and smiled. "I was in a cell like that, once."
"I remember," Ozai growled. "I'm the one who put you there."
"Indeed you did." Iroh was still smiling. "I didn't stay there."
"Did you want something, or are you just here to gloat?"
"A little of both, brother. Don't get so angry."
Ozai turned his back.
"I broke out, you know."
"In case you didn't realize, I can't bend anymore."
"Oh, you misunderstand, brother. I made my escape during the eclipse. I was simply wondering why the great Phoenix King didn't do something similar."
Because Iroh's bad ass like that. And I still say he broke out of jail, left Zuko a note, then broke back into jail in The Avatar and The Fire Lord.
