I'm sorry to hear about Korra, Aang. I know you'll miss having her around, and while I never met her, with a sterling recommendation like that I can honestly say I'm sorry that I never did.

Still, it's probably better that she's at home with her friends and family. I know that probably doesn't make you feel any less disappointed that she's gone, but it's for the best.
