@sjw I voted for Graf because I think he's Quebecois or at least close to those people so I imagine he has a fondness for gravy from all the poutine he's eaten. As well as just appreciating hearty winter foods in general.
p had shown himself to be a ravenous carnist who has little care for foods that aren't animal based. I don't know if that translates into the same appreciation for proper gravy made from pan drippings of a roasted animal or if he thinks even that's a waste of time.
I don't know much about the others and their ability to consume gravy.
