Bolin and Mako in “Unfinished Business”

Bolin

Mako! I'm so happy to see you!

Mako

Uh, you all right, bro?

Bolin

No! No, I'm not all right! I can't take anymore. Listen, I don't want to live in icy bliss with Eska! [sobbing] Don't make me! Oh, please, please don't make me.

Mako

Uh, hey, if you're that unhappy, just break up with her.

Bolin

Break up with her? You can do that?

Mako

Yeah. Guys do it all the time.

Bolin

How?

Mako

Just tell her you're not that into her anymore.

Bolin

Oh, no, no, I don't think she'd like that.

Mako

Ending a relationship is kind of like pulling off a bloodsucking leech. You just gotta rip it off and get it over with. You'll feel a lot better afterwards. Trust me.

Bolin

Thanks, Mako. I'm lucky you're so good at breaking girls' hearts. [laughs] Korra better watch out.
