I've taken a shine to Katie, and accepted that this means she's definitely not going to last. The women seem like quite a pleasant bunch, in all. Bianca's pleasant and credible, Nurun's pleasant and credible, I quite like Pamela and Jemma and Lindsay. I think I'd peg Sarah as a dark horse - she'll either be hypercompetent or hyperterrible, and I can't tell which.
Chiles seems like he might be the most credible of the blokes. Robert and Solomon seem tediously quirky, Steven is a breakdown waiting to happen, and other than that, there's not much to differentiate the men. Arses with haircuts!
At this stage, it's basically just guesswork, mind.
