With any luck, he'll be less of a mood teenage jackass and more of a suave boyfriend who gets spoiled by Asami while they also fire bend around town looking fine as hell. I'm about nearly done with Asami, she isn't so hard but I know it has to be done carefully for Mako's sake. I mean this is them kind of burying the hatchet finally and hopefully something similar could be done for Borra too but as far as Bolin is concerned, it's water under the bridge (hurt feelings aside I mean) he doesn't hold anything against Korra.
