I LOVE this kind of stuff, especially when my gang seems to be doing well.
I think these folks have shared clothes all along, so we can't peg someone by their clothes.
I noticed that Holly, Charla and Tara are standing behind Scott, Dave and Keith, but Amy is standing next to Beau. Usually the girls are standing next the guy when he has to choose between two girls.
So here is my GUESS: The couples weren't sent to the couch, because one of the girls in a couple wasn't safe. Beau had to choose between Amy and another girl. Beau chose Amy. The booted girl chose another girl to be booted with her. I don't know why, but Mel and Desi are both booted. That is why Scott is sitting differently than we would usually see him, and Tom, Beau and Amy are upset.
