Bentley is a challenge to Ashley and since he is indifferent about the connection with Ashley because he don’t care, he shows more confidence with her than most of the other guys. I agree, the mask should come off, problem is, he’s waiting too much for the perfect moment. When he got that alone time with Ashley, he should have taken off from the beginning, instead of a big speech and risking interruption. I think he is a bit insecure, and he is using the mask to be memorable with the viewers. As far as Bentley, I wouldn’t be surprised if he stayed despite telling Ashley that he wants to leave. Again, it’s that challenge thing that makes Ashley feel he is different from the rest.
