A good question! At first I couldn't think of anyone on the show that I identified with, but ... by George ... there is someone:
Professor Stokes!
As my mother would confirm, I always had my nose stuck in books as a child. And what did I grow up to become besides mildly eccentric?
A librarian. Well, good old Stokes is an intelligent, scholarly man who must love his books and appreciate his own company. However, he is always gracious and quickly comes to the aid of his friends. Ever the voice of well-researched reason in the nightmare world of Dark Shadows, I can relate to him very well.
Also, I always liked most of my college Professors and even thought I'd marry one some day. Hey, it can still happen-
Being someone who has had her share of impossible crushes and infatuations, I can also relate to both Barnabas and Julia, although they do drive me batty at times.
Yours,
Happy the Bookbat
