Vittorio was saved by his showmance with Evelyn. The show wants their drama.
Rich should never be given immunity. He acts like a jerk when he is safe and doesn't care. Rene is just a sexist jerk and doesn't think any of the women should be there. Of course Rene and Rich worked well together. But I don't like giving any of the chefs immunity after a QF. I think an advantage to the winner would make more sense. When they feel safe they don't really care. It is interesting how often the QF winner has one of the worst meals in the challenge.
