So Tenzin is the meat of the post, I don't think I'll need to explain.

Mako and Korra are just full of feelings right now and while Mako is accepting them, Korra feels she might be overthinking things but at the same time can't deny that Bolin's got some positive vibes to him. Consider it the prelude to her finally realizing she likes him like he liked her, and how uncomfortable it is to feel that way for a while X.X Mako and Asami are just the cuties right now.

I don't think I have to say much more except I finished this at 6:45 a.m. without rest. Hope it was worth the considerable wait. 

EDIT - I actually feel like I forgot something super important. Could just be my anxiety, but if there's a piece missing somehow, or somewhere, you know why X.X
