Espionage runs in the family for Bon Bon/Sweetie Drops.
Namely, she's the daughter of well-known Equestrian travel writer Bon Voyage, better known to the Night Guard's intelligence division as Dead Drops. (With another one of those marvelous double-meaning cutie marks, inasmuch as a small scroll in a small scrollcase fits "writer-on-the-move" just as well as "covert messages". In much the same manner that a trio of wrapped sweets fits "confectioner" just as well as "keeping things under wraps".)
Writing this down since it came to me in a dream and I think I'll keep it around for future use.
Huh. This is almost exactly my headcanon for her father. I just use the code name Bon Mot. (Her mother, Sugar Glaze, was less than pleased when she found out. Now she calls herself Aspartame whenever her husband mentions his job.)
