Yeah ... Aubry was robbed!
Jason and Scot were bitter jury members.
But Michelle did win when she needed to. And Aubry didn't.
All the people going to the end were recognized threats for their ability or for their jury relationships. They knew they needed Michelle out, and they didn't get it done.
P.s., Michelle has some major brains -- between winning the last puzzle and that memory challenge -- she's packing some major cranial power which she didn't make obvious except when she had to.
