I'm not lazy, I just don't want to go back and cringe lmfao. They were gonna go off and do something and Mako confronted her. I will say that Korra's not going to be that enthused given how Mako looked at her when it was done, but she won't be sad. Probably just as confused as Bolin lmao. 

It makes Mako worse if instead of getting ready to go out that night, he was going to confront Korra about something like that. I say it was out of the blue, but not entirely unwelcome. Mr. Sato can be gone doing evil Equalist stuff and that can leave Asami to tear Mako a new one.
