Some things I've noticed about Peter are that he seems more comfortable interacting with Rachel when alcohol is not in the mix. For instance, when they have the sporty group dates in the gym settings he is always the first one to go over and grab her and pick her up and twirl her around. In the light of day he seems very attracted to her, but when everyone starts hitting the cocktails he seems to get reserved. I know some men get really turned off by women who have been drinking, maybe Peter has an issue like that.
I thought the conversation with Bryan about where they would live, if his parents would accept her, etc. really showed they were on a whole other level.
I think one of the non-entity guys, Matt, might be her friend zone/confidant. I caught one scene where she was asking his advice about one of the other guys.
I too, was really sorry to see Alex go. He reminds me a little of Jon Hamm. Hope we see him in Paradise.
I can't stand wearing false eyelashes either -- they are so uncomfortable on your eyelids. I had to wear them for a job one time and they were really hard to get used to.
