1. The pic of them sitting is weeks ago (no Melanie), so don't take stock in shirt colors too much, tho good investigating.
2. It seems to be after vote off, since they are upset.
Concerning the 2 eliminations:
(Only read if you wonder about the 2 who are voted off)
Someone's personal site is showing the 2 same pics and reporting that (this could be speculation, but sounds good):
Scott has to choose vs. Mel and Holly. Picks Holly.
MEL gets to take off someone with her.
Suposedly, Mel has been influenced by Keith from rooming with him all week, and chooses Desiree.
I found this on a Fox msgbd topic and I followed the site, which they weren't allowed to totally spell out and I did follow it. It seems to be someone's personal page (NOT official at all). We don't know how they would know any of this for sure.
