For me it was the question: How would they kill off Sara? You know that Ramsey didn't think she had it, but she had always skated past the graveyard. Virginia is a bit of a weird deal, smart and certainly KNOWS her cooking, but she isn't fast and gets easily flustered.
All of this makes it pretty much a sure Keith and Heather final, although I actually think that Virginia would be a good head chef... just as long as she doesn't have to cook too much
