I am wondering if they are trying to make us think that Jason doesn't meet Melissa's parents, but then something happens to change that. There was one season where the family refused to meet the bachelor and then an aunt showed up. I just can't imagine that no one from her family would come and support her on this.
The other issue I was thinking about was the big bombshell at the final RS; what if it has something to do with Ty. Does anyone remember the previews from the 1st episode, they showed Ty in a tux. Maybe Jason brings Ty out to help him propose tp the F1, that would get a different reactions from people.
