In a recent story about the Night Nurse and Dr Strange I read, she makes the point that although Strange is the Earth's Sorcerer Supreme, he doesn;t seem to know her real name(or at least he never uses it in her presence). I have a theory that Strange(who after all is omniscient or at least in touch with entities that are omniscient) purposely avoids using her real name in case he is captured by supervillains and in order to protect not just her identity(professional courtesy perhaps) and the service she and others provide to Manhattan's super hero community(after all if a hero/heroine is shot or otherwise injured, state law mandates that such injuries be reported to police and other law enforcement agencies, at least some of whose members are in the pay of hoods such as the Kingpin, and maybe even the likes of the Red Skull, Magneto and Dr.Doom!
