I was not surprised by Rhianna, she's been the most manipulative from the start. First Chelsey took the flack, then Rochelle and Philip, then Omar. Rhianna has been whispering in everyone's ear or crying to them then sitting back and quietly watching it blow up all along. Interesting that she says she doesn't show emotion but goes about crying to people. It's all fake. I don't think she's ever been that in to Omar, she seen an opportunity for a shownance and then thought she'd hit the jackpot when he started swearing at her and she could take on the role of victim. She took that card down last night with no emotion whatsoever, then she's off smirking and bitching about Rochelle before putting on the waterworks in the snug with Yas. All fake.
Saying Rochelle dragged her into things when Rhianna was just as bitchy, except she did it behind people's backs planting seeds with the louder ones and watching them then go and argue with the others.
ETA Rochelle, Philip and Omar aren't innocent victims in all this, they're not nice people, but that makes them easy targets for someone who wants to manipulate things, more likely to come out smelling of roses if your playing with someone who can easily take the role of the villain.
