You've just described fanfic's MARY SUE exactly...and it's a character in the show! I agree with everything you said about her. She seems to lack the motivation and experience needed to be in her position, claims ot be socially inept, and yet everyone loves her unconditionally (except for Jeannie!) and she cannot do a thing wrong in their eyes. I thought her actions in The Shrine were extremely unprofessional - and yet no one berated her over it!
