In Book 1 water chapter 20: The Siege of the North Part 2 when Aang,Katara and Sokka tided Zuko up when they where on Appa how did Zuko get out of the ropes?
70% probably because Iroh set him free before he scold Zhao (because Zuko was unconsious) 20% he burn the rope. 1 thing about Zuko is he never give up (by Sokka) 10% someone set him free. might be Yue.. but i dont think so. LoL
