I really hope Caroline can somehow manage to stay until at least the final week.
Out of the nasty crew, she would be by far the biggest loss for the series imo if she is evicted anytime soon. Sadly I think she would be gone against almost anyone of her friends if they were all up for eviction, so I am hoping the likes of Ashleigh, Shievonne and Conor will all be up together over the next few weeks before Caroline is.
