I cannot understand why Josh is there and Monti is gone. He seems to feel that he is The God of the kitchen, and he just isn't all that.
Josh - Arrogant and fairly good, one sincerely hopes that as he has already been booted out he doesn't win.
Christine - Good with flavours and plating(!), but I can't help feeling that she has had a lot of luck/assistance. The intention of all the other Masterchefs that I watch (UK, Australia, New Zealand) (OK not the celebrity versions) is to find someone who may be the next superstar chef, the US version seems more to be aiming at finding an half decent home cook. If we are looking at professionalism then Christine would have needed assistance with the soufflé task, and I think she would have big problems running a pass. That said if they are looking for a home chef and have no problems with her having someone do her seeing for her then I think she has a good shout.
Becky - Consistently good, very good at plating (although that is her job) and very good at flavours, frankly it would seem a bit of a travesty if she doesn't win. (But then I'm still in shock over Mindy and Amina not being in the top 3 in Masterchef OZ 4)
