I thought this was an interesting tidbit from Bolin’s VA interview.  

Geek: Okay, to talk about the show a bit, and in particular… The kiss from two episodes back, between Mako and Korra. Obviously fans freaked out a bit, what was that like for you?

PJB: Oh, I know that kiss! [Laughs] I have a problem with it! I don’t think I’m comfortable with it at all… I didn’t like it! Though it’s really uncomfortable for Bolin, because he loves Korra completely - and like I said before, he’s all in. He’s a little innocent and naive as he goes through life. So naturally he thinks if he likes Korra, Korra likes him, and he told his brother about it. I think that makes it more interesting because he’s more overtly blown away by it. There’s nothing in his body that can fathom that his brother kissed the girl he likes. That just blows him away.

Geek: So do you think he’s going to end up with Korra eventually? Is that what you’re pulling for, I imagine?

PJB: The thing is I can’t obviously tell you that, but Bolin would obviously love nothing more than that to happen, but we’ve all - everyone in life has gone through this. We’ve all liked a girl, or our friend likes a girl… Whoever gets her first, the other has got to back off. Obviously there’s a scenario here where you realize you like this girl, but she likes your friend, so you’re going to have to deal with it. Whatever scenario plays out, where I have to deal with it, or maybe I do fall in love with her…

Bolin is a really good person, and over time, he’ll figure out what the right way to live his life is. I can’t give you too much here, but he’ll be okay. He always sees the glass half full. He’ll figure it out, and obviously it’s his brother, so they can only hold a grudge for so long. As far as anyone out there, the person he can depend on the most is his brother Mako, and now Korra is stepping into that world as well.
