I don't want Bianca to turn heel, and I'm surprised at how many people are hoping for that.
If she does turn heel, it should have nothing to do with the Jade stuff. I don't think she had anything to do with it and with the way the story's playing out, it doesn't make sense.
So, Bianca needed to find out information she already had, went through all that crying in front of a live audience, and also allowed Naomi to get her ass beat twice for something she told her to do? All so Jade wouldn't find out it was her? It's not adding up.
My prediction is Bianca turns heel at some point and she realizes why Naomi attacked Jade, but it doesn't have to be a situation where she was the mastermind behind it. It just seems convoluted at this point.
