Seemed to me he pretty much got friend zoned in that episode.
The only thing that they really left open was that Korra and Mako like each other and they aren't really sure what to do about it atm since he's going out with Asami.
I'm sure he'll end up with some sort of romance with someone before the series ends. They kinda made sure most of the main characters did in TLA anyway I could see them throwing someone in for him.
