So if I had to handicap the remaining (no pun intended, Sarah), I'd rank them in order of anticipated elimination with #1 being my guess as to the winner:9. Tall blonde w/ no chance8. Lindsey 7. Sarah (a case could be made for her to be #8 or #9, but she won't be)6. Vegan who "eats meat"5. Selma 4. Tierra (she should be gone much sooner, but he'll keep her around so that people tune in)3. AshLee2. Leslee1. Desiree
I actually think Catherine goes further than 6. She has pretty much told him she is fun in the sack, so I see her making it to the fantasy suite. He can call it his final fling before he marries his wife. While I prefer Desiree, I could see her going out 4th as I think he thinks she is overthinking things (I don't).
Now I see Desiree going out 4th because her brother is a psycho (based on the previews).The alternative is she makes it to the end, and she doesn't show up for the final rose ceremony because of the conflict with her brother. An earlier preview showed Sean being given a letter at the end by Chris Harrison. It could definitely be from Desiree due to Psycho brother.
My wife thinks psycho brother could be a prank. Based on the preview, I would be very surprised if that is the case. I'd also like to know whose dad says he is not sure if he can give his blessing. If that isn't Desiree's dad, then it has to be Ashlee or Lindsay's. Since Catherine's dad lives in China and once tried to commit suicide right in front of her.

So we have at least two and potentially three very negative encounters with the families. Putting myself in this idiot's shoes, if I have one chance to meet a girl's family and then have to decide whether to propose, anything negative at all is very likely to eliminate that girl from consideration. And the dad's reaction, Desiree's brother, and Catherine's sisters are all what I would consider really huge red flags. If he proposes to one of them despite these things, he's even more of an idiot than I thought.
