Trash Michelle all you like, the fact is Dan felt strangely threatened by her.
I also think Dan\Memphis couldn't handle that Michelle is an emotional person.

We've seen on Survivor many times, where Becky and Sundra types hook up with unbeatable males and ride to 3rd or 4th with no chance of winning (unless the jury is ultra-bitter). To complete the analogy, I guess Ollie would be Adumb.
