I'm looking for a post-series time travel fic about the final war. Dark Willow sends Buffy to correct the type mistakes! Welcome to Hell's Mouth part deux by Offyourbird. The spell is performed with human bones. In one of the times that she returns to the present, the one who sends her back to the past is Wes. The last time she returns to the present, after she made all the changes for her, she shows up at a supermarket and Dawn is waiting for her and takes her home.
Thanks since now!
