My two cents:
I think Reid does come back and tells Jillian he was falling in love with her. In the limo he seemed so upset with the fact that he was feeling love for her but he hadn't let her know. On the bench he mentioned that he wished he could have been more upfront faster, but that he didn't even know if that would have changed anything. Just like Jillian gave Ed another chance so that she would have no regrets, Reid would be doing the same thing. Whether she goes with Ed as so many of the spoilers suggest for f1, at least Reid would know that he put the ball in her court.
I have been a Reid fan from the beginning and would love for him to end up with the girl, but I think she will go with Ed. Good luck to them all!
