Kratos
The big man comes with red meat. Not all of it is - ahem - industrially packaged. There are hunks of things in wax paper and nobody informed him that there is such a thing as an apron. He brings some knives because he obviously assumes that no one Rey knows has ever seen a sharp edge. But anyway, he comes with it all in a big cooler, several minutes behind Ren on arrival. His son, Atreus, also comes, and for once runs around throwing a ball and generally behaving like a kid and not a twelve-year-old adult.
Kratos doesn't so much as offer to staff the grill as take it over. Like whales eating shores of krill.
