The final meet the bachelor's parents is also a great predictor. I especially remember thinking that when Mer's parents met Ian they would not like him, but who'd a thunk it that Mer's mom and dad definitely saw Mer's attraction and then Fleiss also showed that Ian actually DID want children etc, just not yet.
Of course Kirsten's trip to wine country goes down as an all time example of way to screw up your final rose chances. Fleiss definitely edited Kirsten's visit more negatively than Jen's, and then when Andrew's bulldog brother got hold of the info on standby Bill, it was all over.
That's why I'm agreeing that if this edition was Bachelor Survivor, Sarah S will outlast the others, making fewer waves and walking away at the end the winner. If Sarah S's family gels with Travis and he feels comfortable enough to invite them to his place for dinner, she scored far more brownie points than the others because IT'S SOMETHING THAT WOULD HAPPEN IN REAL LIFE! You definitely can't dismiss the familiarity quotient.
