I agree. Hmm, I think Katara approved of whomever made Tenzin happy, and that was both, but for obvious reasons probably wanted Lin and Tenzin to be together first. That being said, she loves her grandchildren, she loves her son, and she loves who makes him happy. Lin and Tenzin were unhappy with at least several factors leading to their split, but I really doubt Katara held it against her or him. They're friends, not enemies, and it was good enough for her. And yes, yes, of course it will be mostly for fun. If she wants the hardcore training to condition her, then she knows to come back, they'll work her.

I have another rp I need to post in later, but I'm going to get to this one too tomorrow at least once, we'll see how my energy levels are <3 fun times ahead.
