Mrs Waverly. Why do we assume spies can't get married? Other than we like to think our heroes are available. So who is the exceptional Mrs Waverly? A childhood sweetheart? A college romance? A nurse or ambulance driver or pilot during the war? Someone in the office? A fellow spy? A spy for the other side? A librarian he met post war?
I personally always saw her as a nurse Mr. Waverly met when he was injured on a recon mission. She would have to have to patience of Job to put up with everything that UNCLE does.
What about you? Have you ever wondered about the woman who managed to get Alexander to say, "I do?"
