This is awesome, of course with Izumi, Lin and Su we have yet to know who Izumi's mother is and who is the father of her son Iroh, and in one episode we learned who Lin's father's name is but we don't know Su's and we still don't know why the girls never met their fathers or what really happened in Toph's relationships with them since she said they "didn't work out" which could mean something happened in those relationships that might've involved death.
