Could lead to some good TV. Not just for the obvious reasons but mandy using Sonya's crush on her to manipulate herself to a title run could be fun.

That's probably just a tease though. They'll either piss off the bible thumpers, or even the lgbt community itself if they feel like this angle isn't done right. They'll probably dance around it for a bit and then pretend it never happened
