I read a fic based on this once which was great. Does anyone know of a fic were Buffy does not receive the memories of Dawn when the monks alter reality? Thanks

Edit: Thought I'd explain a little more. When the monks make Dawn human and insert her into reality, they stuff up (I think) and it doesn't affect Buffy's memories. She comes home from Dracula's castle and everyone remembers Dawn except her and she's really confused. I remember at one point Buffy yelled at Dawn something like, "Who are you?!?!?" and everyone else was all "WTF?" and I don't remember that much since I read in something like 2009.
