TBH I'm surprised that KH has got this gang mentality and thinks people should take sides. In all honesty hers is the only gang in that house. Perez and Nadia are friends, as are Katie P and Keith, but that doesn't mean they don't mix. Right from the start KH wanted to isolate Perez and get everyone on side...she succeeded to an extent but the so called fence sitters wouldn't comply with her demand, and that's what riles her. if she had her way they'd be non stop arguments and that, in my eyes makes, her immature.
If I was in that house I wouldn't play her games either. I'd make the effort to get on with all of them, after all it's only for a few weeks.
