That's wonderful news, Aang. That you'll have a granddaughter some day. Though I'm sorry you don't get to see her anymore, but cheer up! That's probably for the best she isn't here anymore, so she can live peacefully back at home.

[She's not sure if Jinora going back home really is better, considering she has no idea what life is like back in Aang's world at her time. But best to look at the positive side.]
