Emily Gilmore Remember, the title of the show is Gilmore Girls, plural. Lorelai and Rory initially may be the main focus, but once matriarch Emily Gilmore enters the picture, it's a full-on tripod of strong personalities. Lorelai and her mother may not always see eye-to-eye, but there's no denying that Emily's polished point of view heavily influences all of the Gilmores.
When I first started watching Supernatural, I kept thinking Sam was Dean. It took me a full season to really grasp who was who. Then I remembered that Jared played Dean on Gilmore Girls. And it all made sense.
