In season 5, she dies of an [[aneurysm]] after a tumor is removed from her brain in "[[I Was Made to Love You]]". (In the [[...|first episode of season 4]], Buffy jokes "Can't wait till mom gets the bill for these books; I hope it's a funny aneurysm.") Joyce is one of the few Buffyverse deaths from non-magical causes. She returns for one Season 6 episode, "[[Normal Again]]", as an hallucination (or possibly as herself in an ). She also returns in some Season 7 episodes as either a manifestation of [[The First Evil]] or as a ghost.
