I thought it was a good episode last night (and I stand by my previous comments that most people can be edited positively or negatively and we, the audience, are pretty well manipulated).
I didn't like a lot of Hallie's behaviour, but I can say the same about Dylan. He is a bit too controlling and intimidating at times.
I don't think Paul fancies Olivia at all, but I think her behaviour is a bit off towards Paul at times. Maybe she just likes "slut dropping" (awful term) and strutting about though.
