I felt as if the emotion behind Nicole's tirades at Malik and Kevin was based on her attraction to Malik, like someone said. The issue at hand is that Malik is pursuing other women...the fact that these women are not Black adds insult to injury for Nicole. She's very judgemental, and has strong unbending ideas on what it means to be "Black" in America, and demands that others fill this description.
I thought she was going to cry when she was jumping on Kevin...did anyone think that she just flew off the handle at him? Even Coral doesn't go off like that.

Also, Nicole is burning some bridges with some of her housemates..."don't talk to me for the next six months!". No WONDER the E!online article said she didn't have any good friends in the house.
