You know Azula now that you mention it Bolin being platonic friends with Asami could work out well. Asami has a shitty life and how she isn't depressed 24/7 is beyond me but Bolin is the perfect character to always make her feel good about herself.
Plus it'd be really nice to finally have a boy/girl relationship that isn't romantic. I swear those are rarer than gay relationships.
It would also strengthen half of the group in one swoop. Team Avatar seriously needs more bonding and growth. It's been non existent! Bolin and Asami just make sense. Or at least they did.
