Funny how Chris was insisting that TPTB chose Ben to be the Bachelor because he was ready to take the next step. Maybe Ben did take the whole Ashley rejection thing pretty hard and thought this will be his way of getting "revenge" - just play around and bang a model in the process.
I thought this before the season started, but decided to give Ben the benefit of the doubt. Now, I'm back to believing this. I think this season was all about promoting his business and boosting his ego after last season's rejection. There was an obnoxious clip in the promos (ultimately excluded from the first episode) where Ben thanked Ashley for rejecting him. Every time I saw it, I laughed and thought to myself that she's probably happy she didn't didn't pick him too -- and that was before the season even started and we got to see what a jackass he is.
I don't think Ben was ever serious about this, and all the women seem to be confirming it post-show. I know it's Harrison's job to try to convince us otherwise, but I think he actually made matters worse by proclaiming Ben "the most sincere Bachelor we've ever had" before the season started.
