I'm not really sure if this has been discussed, but I think Vienna is going to eventually have a good edit if she is the F1. Remember at the beginning of Jason's season when everyone thought Melissa was too young to be a step-mom and want to settle down. And that she must be immature if she was a cheerleader. But then she and Jason went on that 1on1 with the blimp and she told Jason about wanting to start a family. (He had initially expressed concern about how serious she was.) After that she was a fan favorite and had convinced Jason she was ready. I see Jake at first being concerned about how serious she is, and then they go on a 1on1 and she talks in depth about her marriage and then the viewers (and I guess Jake) will see her in another light. I think being married, no matter how young you are or how long it lasts, makes you grow up and most of the time mature.
