I also reviewed the previews for today and as I slowed down the VCR to frame by frame, PH showed a clip of the roomate selection....In order from left to right:
Desiree, Amy, Melanie, Holly, Charla, Tara
In another clip as per other posters, I agree....
Charla with Dave
Holly with Scott
Tara with Keith
Beau with Amy
Tom alone....interesting...my thoughts are that Desiree being the one without a roomnate last week may pick last. What I don't get is where Melanie is as she has to pick after Amy (as per how PH does the roomate selection).
1st speculation: Since Tom is alone, maybe Melanie picks Tom, and then at the end Desiree picks Tom and both Melanie and Desiree get booted(since the preview did mention that more than one person leaves Paradise on Monday.)
Another speculation from my part: Today's rule could be that you can only pick someone you already roomed with before, so Melanie picks Keith(her only choice), Tara picks Keith, Keith picks Tara, Melanie is booted, and Desiree is booted too as she didn't have a roomate last week.
