“Undead” is a very broad term, if you think about it. Vampires are undead, obviously, but so are ghosts, zombies, and mummies.
The Vampire Diaries season three ended with plenty of cliffhangers. Will Elena choose to complete her transition to vampire? How will Jeremy handle being the last living Gilbert?
Tara is not handling her new "lifestyle" very well. Pam pulls her off Sookie and puts her in the house. Tara is tearing the place apart. As sunrise approaches, Lafayette feeds Tara, distracting her long enough for Sookie to wrap silver chain around her neck and drag her into Eric's cubby.
