Guillermo will go as your designated driver, Nandor, tho he's been to a few of Nadja's orgies and is still a little like *cover one eye while looking around* while also being a helpful guy that's like "the sex toys are over there" to someone asking.
(He would have been like "if you want me to uh, leave you to something more private I'll uhhhhhhh just go" to Nandor tho just for full awkwardness yw)
