You guys may have alreasy found this
In that episode where you see how zuko got his scar, right when it happened and Iroh looked away you can see Azula there.?? Just by her expression you can tell that she despises Zuko, so I doubt her treating him like she did at the end of tonights episode was real. Don't trust that *****.
It's in the first few seconds on this video:
