aaaaaaaaaaaah omg
[Okay, so this is awkward. Really, really awkward. A lot has happened between Korra and Mako in the past few years — both in Republic City and in the City, that weird interdimensional place where she's spent the better part of the last two years. To make it worse, she's known several different Makos, because time works in strange ways in these places. There was the Mako from her past, who didn't know Amon had taken her bending, and who had given up his firebending to return her life. And there was a Mako from her future, who said she gets her bending back, who said he was dating her and not Asami.
This Mako is in many ways a stranger to her, and she's scared to approach him, because she's not the Korra he knows. But because she's Korra, she can't hide from him either. He's still her friend, and this is a strange new world.
So she approaches him, not with a tacklehug like she would have once, but smiling — happy and nervous all at once.]
