Ron reminds me of River Phoenix looks wise. He is obviously used to women dropping at his feet and his ego is out of control. The comment to Casey about the white jeans, I was waiting for a laugh at the end to show it was a joke but it didn't come. He sounded quite nasty in that moment.
I am sad Aaron has gone as he seemed very decent, but I suppose that doesn't make good TV. You could literally see Aaron's contempt for Ron. I am glad though that Ron is being called out on his behaviour by the other males - and not being told endlessly, 'we have to be tested in here'
Will reminds me of a young Bill Nighy. He has that saucy teetering on camp manner which is very likeable.
