I really like Jenny! I agree with what has been said and think her personality and bubbliness just shines. She and Brad would make a great fun couple!
The only thing, and I mean only thing, is that she is willing to put their relationship on hold for her cheerleading gig. I don't know if Brad will actually be willing to do a long-distance thing and wait if he is actually ready now to get into the relationship. That, if anything, would be Jenny's only downfall.
However, should Brad actually not want to choose Deanna or Jenny, he would pick Jenny. Why? Because she would be easier to let down by having a long-distance relationship be too difficult to continue with. I'm just saying, sometimes these bachelors get to the end and kinda know that none of the girls are "the one".
