I was really bothered by Katara's step-grandad being a member. All the others were notable for thinking outside the bun wrt their cultural traditions. He was notable for being a massive sexist who was bitter about getting dumped. Grangran, and her ability to duck an engagement to run for another hemisphere seemed more likely.

True. I totally can't see Iroh getting along with that guy! Iroh and Bumi would be singing something inappropriate, and he'd be all sitting with his arms crossed and glaring. Where I can see Grangran getting along with these guys - particularly Jeong Jeong, I think.
