Zuko is at his little camp after failing to convince the avatar gang to let him join he is mumbling and talking to himself about what he should have said. You have followed him you want to see if he really is planning something bad or if the gang Just doesn't trust him enough.

Your apart of the avatar gang and have seen zuko from time to time, and he doesn't seem all that bad and he did ask for forgiveness so..maybe he isn't as bad as the others think
