9S doesn't know shit about being fancy, though he sure as hell will be dressed to the nines. He can deal with a rigidly scheduled day and specific sets of manners (if he's taught about it), but he sure as hell is gonna whine about it. His sword and robot buddy will be coming along for the party, too.

He'll be developing a basic map for the Nightrunners, but ultimately he's a curious and nosy busy body so he'll be poking his nose into everything (especially since a fae castle is new stuff to him). He doesn't really know the RM well enough to be uneasy at her unease, but since everyone else who's been around longer is on edge, he'll at least try to stay out of trouble.

Try, being keyword here.
