"Raynaud" is the title of the leader at a meeting of Already Ghosts at a Blue Hand club. As there are many Blue Hand clubs in many cities, there are many Raynauds; the Raynaud may even differ at one club from week to week. The title comes from Maurice Raynaud, a nineteenth-century French physician who discovered Raynaud's disease, a disorder which may cause hands to appear blue. The only Raynaud seen on-screen is Jeff Slingerland. ("The Gift")
