Richie and Matt, of course. If anybody can get Matt to dance, it's him. Matt is a move your body awkwardly to the beat sort of dancer, not very good. Mmmmmmaybe he'll suggest they break away for a while?
Elsa's dance card is about to get even fuller with Stephen, Thor, and Pikachu. Stephen asks how Elsa is doing, Thor starts to flirt, Pikachu will perch.
Stephen hangs out with Mobius, bringing him a drink if he doesn't have one yet, chats him up. Thor will come up to Mobius and be the kind to SLAP HIM ON THE BACK GREETINGS MOBIUS! WHAT A WONDERFUL PARTY!
