From the choices you listed, Korra and Bolin. I like Mako and Asami better, cause she seems to make him less of a jackass while he makes her feel safe. emotion_kirakira Also, I could see Mako saving her from being used.(Not saying that she can't handle herself, she just seems too nice, and yes thats a personality flaw) I just hope there isn't an alter motive with her because It'd be obvous that they'd just bring her in to make coflict for Mako & Korra. stare
But it looks as though Mako and Asami aren't going to be together at the end. emo
It also look like Korra and Bolin had a great date and is just better. Not only do that have some things in common, but it seems Bolin is more calm and can make Korra think bofore she acts. The only problem here though is that Korra only cares about getting into Mako's pants. emotion_facepalm
I wouldn't mind a 3some or 4some(with Asami) of them, ether.
Anyways, I'm more of a Korra X Lin or Tahno x Korra x Bolin,(YES! I'M NOT THE ONLY ONE THAT LIKES THIS SHIP! biggrin )Bolin x Tahno, and of course, Mako x Asami fan.
