As far as all of the comments and interviews with Jake saying 'I fell for more than woman', or 'I loved more than one woman' blah blah blah, of course its not true!! Thats the kind of stuff MF and producers tell Jake to say to mislead viewers. Of course Jake has to act 'heartbroken' when letting women go. Would you want your bachelor standing at the podium to send girls home with a big smile on his face, knowing he was all that much closer to being with the one he truly loves???
I'm sure that Vienna is well aware of how it works and why he is saying the things he is saying. I also am quite confident that Jake and Vienna have seen each other all throughout the final process. The network helps them out, for sure. I'm sure he has to say " I havent seen anyone..." to mislead everyone. Kinda like Mesnick did when he was seeing Molly behind Melissa's back.
