Good point about her motivation. I think it goes back to their 1 on 1 date. He said something about needing to see her loosen up (if I am recalling correctly). That was why the 1 on 1 was that 50s diner and out of character costumes. It went well, so I think these two are getting close past just the physical thing.
I still think that Shayne is just a physical attraction (albeit a very large attraction). I can't imagine that Matt will want to be part of her life. I can't imagine getting involved with a family that is SOOOO high maintenance.
I was sad to see Noelle go. She was probably the most grounded girl, but maybe didn't light the fire in Matt the same as the others. I really didn't see much difference with Chelsey, so suspect that she is gone next (especially with her intimacy issues and the theme for next week).
As I recall, Amanda was the first out of the limos in week 1. I have no spoiler info, but she is my pick to get the final rose and the ring.
