I quite like Caroline - at least I think she's a good HM, not sure about her as a person - but it would be more interesting if Benedict stays in.
If Lauren stays in she's just going to continue to be wet. Benedict will be more of a challenge to Caroline and others. He doesn't care much if people don't like him.
If Benedict was to go she would do her typical frustrating celebrations.
If Lauren doesn't go this week it's only a matter of time because she's constantly playing the victim role and that weakness is an easy nomination for a HM to make.
I like Lauren too, but she does do a lot of misery, then a bit of larking about, then a bit more misery. We've got quite a few weeks left and Benedict seems to have more to offer.
