Okay maybe I am crazy but here's why I think Rob took Paige over Laura:
1. Laura is overbearing/too much for him because of her size, stature
2. He felt guilty about embarassing Paige in the car
3. Paige is playing games with his head (such as the comments about sleeping with him and the trick she pulled near elimination by not seeing him).
4. Producers. Those *sick* producers. Gotta keep it interesting. :nono
I wonder what they said to Rob about not taking Laura. This happened on the Bachelorette with Trista too - she took this awful guy Greg that she had no interest in because the producers told her to. I wonder if they offer money or if they sign some paperwork that says they have to comply with producers' requests. Rob didn't have anything to say to Laura which was really suspect. It's disappointing too because I think that would have been the spice this episode needed at the end.
At least Paige is around for added drama. Loved her speaking for Kelly to Erin in this ep. Paige is no angel.
