I think one of my favorite realizations from my AtLA rewatch is how often Iroh was just vibing with the Gaang, even when Zuko was still trying to capture them. Pirate episode? Iroh's just standing right next to Katara going "yeah this kind of is your fault". North Pole? Iroh's got a whole scene with Katara and Yue. He even gestures to her to stay away from Aang at one point and she actually listens. Tea with Toph. Man truly spends the whole show vibing with everyone
