I think what Bryan did was super classy and absolutely the right thing, helping Kevin out with his sous vide. I'm not sure I agree with him, though, that his brother would have done the same thing. Mike V. doesn't really seem like the kind of guy who would step up like that, especially considering his little digs at Kevin in the past few episodes.
My girlfriend and I were saying that Kevin, after the shock of winning the challenge (and a chance to take a spot in the Bocuse d'Or!), would probably offer Bryan some of the money he won, and that Bryan would probably turn it down. It's pretty amazing and heartening to see some real strong talent this season, but even better to see some great people doing well. I would totally hang out with Kevin or Eli.
