I think the only reason GR keeps keeping Jen is for the "drama". How many times can you lose or mess up and blame someome else. It's never her fault. Always someone else. Can't wait for the episode where she blames GR for her shortcomings.
Did we need 12 bikini models in the episode? Are the ratings that poor?
Jen needs to go. She might be a decent cook, but she's proven to be dishonest over and over again, isn't a team player and can't accept responsibility for her actions - a lethal combination in a kitchen.
Final two for sure should be Corey and Christina.
