Ryland's costume was not a loin cloth. It was, much more boringly, a dentist. Mostly because he had been busy and almost completely forgotten he needed a costume at all. Anyway, the point of the party was the alcohol, not his costume, so he wasn't terribly concerned.
Unsurprisingly, Pete was relatively easy to find. More surprisingly, this was because he was rolling around on the floor with someone attired in a lot of gold feathers.
Ryland momentarily surpassed the drink table and aimed towards the kerfuffled instead. He kicked lightly at Pete's arm when he got there and grinned down at him. "I'm a little late to the party and you've already found someone to replace me."
