Brian told him exactly how to cook
To me, the most telling part of that scene was when Brian was talking about sharing, and said, "Would my brother have done it? I'm not sure." I think everyone else is quite sure, though, that there's no way Michael would have done that.
Michael is certainly creative, and one of the most techniques-oriented competitors they've ever had. But in the real world the mark of a great chef is somebody who can prepare consistently high-quality food, day after day. In that regard, both Brian and Kevin have it all over him.
A great chef also has the ability to motivate others to excel. And in that regard, Michael is lacking. Throughout the series his approach has been "hey, I'm the only one in this kitchen who matters, and the rest of you are just taking up space."
There's someone just like him on that new Chef's Academy show. The guy brings two things to the table---nine years experience as a professional, and lots of attitude. Interestingly, of the two challenges so far, he's lost both abysmally.
Meanwhile, if Jen can maintain her focus, I think she still has a shot at it.
BTW, if I understand the promos correctly, there won't be a new episode until December 2.
