Re: DID YOU COME?
Hunter and Ben both came to the party.
Hunter helped with Luz's purchasing of bottles of soda and snacks and some juice. Likely apple juice as the best thing he knows is apple blood and that's the closet there is here. He got a swimsuit since he also got dragged along for that, but no one will likely see it as he's just running right on into the ocean with all his clothes and not caring.
Ben would've brought whatever burgers and hot dogs he could find for the 1940s that'd sell to him. As for clothes, he's just in whatever Derleth put his toon form in.
