LOL - I'm kinda glad to be surprised by this, if I'd known you were apping I might have been tempted (again) to bring Kat back. I will just try to happily settle on Piper and Korra CR because what is having enough time.

They can become brosises and Piper can basically be her not-Asami and Piper can ask all the questions about Korra's world mythology at some point.
