Malarkey does not self-edit well, and that made it an easy choice. He made two dishes that tasted well enough on their own, but he in no way captured the essence of the original dish, nor did he stick to the core principals of the restaurant. His dish was flawed conceptually. Sometimes the judges favor taste. Sometimes concept. I think if his duo complimented each other better, he might be going to Italy. I will not miss his shtick.
Gregory needs to regain focus. I think he is a little worn out. If they get any sort of break before Italy, maybe he can recharge.
The odds are clearly not in Stephanie's favor, but I'm really proud of her, and would not mind at all if she somehow pulled the upset. That said, I would be fine with any of the final five winning. I find them all likeable, and the person left at the end will clearly have earned it. My gut says that it will come down to Melissa and Voltaggio...as long as he gets challenges that allow him to cook his food.
