I watched this ep. I thought Nat was sweet checking on Kate after the challenge, and I get it that Kate was icy at the start of the conversation, but seemed to thaw a bit at the end. I guess Kate's view on life is "get them before they get you" everyone's out to have a go. Not a nice way to live life.
And then there's Lisa *my way or the highway* Curry. Kate and Nazeem have their way, if he wasn't happy with it it's up to him to say so. Getting pissy at Kate for not jumping when she said to, then getting told off by Jay for going to take the washed utensils back.
So, yes Mr Stickyfingers, I think Lisa is acting a lot like JoBeth was. But I don't think Nat is aware of the clique thing.
To sum up, Kate is a prickly bitch, they'd all know that after 2 weeks, take your own advise Lisa, don't poke the bear.
