Regarding Chris' chemistry with Kaitlyn - I do think she was one of his frontrunners early on. He seemed really into her during their one-on-one time at the zombie date, and the way he was so ticked off at Britt for criticizing him for giving a group date rose to Kaitlyn on the camping date makes me think she hit a sensitive nerve. I think she's lost ground though...they never seemed to develop a deep connection, but I think he likes her playfulness and honesty. Kaitlyn definitely strikes me as WYSIWYG.
Jade - I don't think Chris was all that bothered (although probably embarrassed) by her nude pics - but I question, and maybe he did, whether that is really in her past. I don't see her as being ready to settle down and have kids. Seems like she still has some wild oats to sow. I don't think she's a bad person and I don't judge her, but I think she has more maturing to do. Chris didn't seem upset at all by Kaitlyn and Ashley I. taking off their bikinis on the camping date (and now that's been seen by the whole world albeit blurred), so I don't think he's uptight about that.
Becca - I don't think it's weird to be a virgin at her age, I do think it's a bit weird to not have had a serious relationship and so seemingly shy sexually, but some people are more reserved and sheltered, so OK. But why would she come on the Bachelor where you know the guy is dating multiple women, making out with as many as he can and probably having sex with more than one - just seems like a very odd choice for someone in her position. Wouldn't she want someone with similar values? Personally I think she's awesome, she just seems like one of those people you have to spend some time with before they come out of their shell.
Britt - I think she's gorgeous. I also think she's fake. Something about her does not sit right with me. I think she was torn between "winning" and being the next Bachelorette. I think Arlington freaked her out, and she realized Chris was serious about her, so she decided the time was coming to get ready to bail. I have a feeling she would have liked to have made the final 4 or 3, if she could have convinced Chris to keep her that long, meanwhile she would have sown enough doubt that her leaving voluntarily at the point wouldn't have been a huge surprise and would have set her up perfectly for the Bachelorette. But Chris pulled the rug out from under her. We'll see if she goes into "save" mode at the WTA.
