After watching the show for what 5? seasons
they have a narrative formula that begins with each season have basically the same cast of characters -- the stupid haircut guy, the couple of obvious hicks who are place holders to be sent home in the first couple of shows while we are still just learning everyone's names, the hyper maniac who is pretty good but tempermental, the interesting experimentalist, the quiet professional . . . and so on.
Two seasons ago it was clear very early to me that the Asian guy was going to win.
Last season it was obvious it was going to be a woman and Stephanie was clearly the best of the women.
This year it is going to be one of the Europeans, and I'd put my money on Fabio.
Jamie looks destined for the final four, and Adraine too, though Adraine could be this year's Dave (from the first season), who has a brain freeze and misses the finals with a silly mistake.
There are a couple of things to keep in t -- the show is edited after it is all over, so the narrative arc can be built in after the results are known, and that allows for the foreshadowing (this year pointing to the Europeans).
And secondly, at the end of the show they flash -- very briefly -- a disclaimer that some of the judges decisions are made based on other criteria than the eria that may well include "we have to keep the quirky weird hair guy arround because he is such good television" as his actual in the kitchen.
All that said -- I think the chefs on the show are actually pretty good, the first few episodes had some of the most interesting food, I something about the vibe has made them timid and cautious and I think the producers realized that in the middle of production and last week, bringing in a new brutally honest judge, and having them watch the judging in action was designed to shake them up and get them out of that deviled egg rut they were all falling into.
