Add to that the strict authoritarian stance . . . if you hadn't told me beforehand he was Aang's son, I would think he was a descendant of some airbender, bitter from being in hiding, or something. Tenzin, Y U NO like Aang? Or Gyatso??
I waasn't bashing Aang by any means. I just meant that he was peaceful and only resorted to violence unless he had to. But something about Tenzin, maybe it's his voice and the facial hair, make me see him as a more opposite version of a monk.
