Into every generation a slayer is born: one girl in all the world, a chosen one. She alone will wield the strength and skill to fight the vampires, demons, and the forces of darkness; to stop the spread of their evil and the swell of their number. She is the Slayer.
I really like Willow putting down the stones on top of Tara’s grave. The beginning of the seventh season had the theme of going back to the beginning. Willow, at her heart, is still a Jew. She might not practice, she might not even believe in the religious aspects of it anymore, but there are certain things that she still carries with her. This tradition is one of them.
