Fun parallel between Iroh trying to help Zuko find his path and Damien trying to help Manny set things straight, too. Also, I think I mentioned this before, but I don't think I'd particularly enjoy playing in the campaigns these guys run. The IC/OOC line is blurry to the point of the players taking personal offence if something happens to their characters, and they seem to view campaigns as being something to be beaten rather than a game to play.

That said, I do agree that I think Damien would make a good DM. Bearing in mind the ending to Legend of Aang, I'm going to predict he's the one who DM's Korra.
