I'm looking for a word to describe a younger person that is unknowingly receiving guidance from an older, wiser individual.
The older person could be considered a mentor, and looks upon the younger as his protégé, but the younger doesn't consider their relationship that way.
In his mind, it's just an older friend who shares his stories, and it doesn't necessarily occur to the younger that he is being taught anything, just casual conversations with a friend.
EDIT: Added the tag for a short phrase as well, and an example usage such as:
The wizard's protégé learns of Powers he never dreamed of.
Want to suggest that the protégé is not aware that he is a protégé.
