Where Hiroshi should end up going has been a point of contention for a while, on account of his Walking Spoiler nature.

"Sweetie, I wanted to keep you out of this as long as I could."

or

"These people, these benders. They took away your mother, the love of my life."

I like the top one. And if we don't spoil-cover it, it will draw many questions as to who he is really.

I'm in favor of "So, I hear you're dirt poor."

Hmm. That's also a good one. And no need to worry about it spoiling anything.
