Something occured to me
Anyone think it is possible that Jesse's screw up with the final rose was planned? Since his mole was getting a rose for sure and she isn't a "real" contestant, the screw up adds drama and allows them to keep the 15 bachelorettes and gets the sympathy/underdog support for one of the girls. Doesn't seem too far fetched since we know the lengths the producers/editors will go to for drama.
