['The Vampire Diaries' - 'The End of the Affair']
I'm not one to pick favorites. Some people can name their top five favorite movies/songs/shows/etc. upon request, and some are doomed to a life of indecision. I'm one of the latter -- honestly, choosing five episodes of 'The Vampire Diaries' for our "Essential Episodes" series took about two weeks. But there is one thing I'm absolutely certain of: 'The End of the Affair' is my number one favorite 'TVD' episode of all time.
Alternately heartbreaking, hilarious, beautiful, engrossing and 100 percent enjoyable -- what more could you ask for in a high-school-set teen drama?
