Ha Ha , GMTA, it's funny I just posted the exact same thing before I read your post.One comment of Brad's last night that stood out to me was when he described Emily as classy. In his last season, Bettina was deemed to be too classy for him. I don't think Brad ever said it but that was the consensus by some. Bettina and Emily are both blondes, upper class, and both have a similar quiet personality. If Bettina's family had been more receptive, I believe Brad would've chosen her. So with Emily being F1, we now know Brad's type. Arguably it can be said that he let Bettina go, but we have to remember that season that he didn't choose anyone, so it probably was Bettina or no one. Interesting also is that both Chantal and Bettina were divorced. Enter Brad as rescuer from failed relationships.
I also find it curious that his F2 are from the most prominent (and probably the wealthiest) families on this season. So Brad does have a type.
