The world is ending or they can't win the fight and they all agree to do a spell so they can start over again. They all turn into small children again with probably different parents. If Im right Merrick will become Buffy's watcher again. Giles is young, probably 19 again and . Dawn will be born further in the story. They remember everything that happen before. Buffy will become the Slayer again. Xander and Willow live together, Giles lives in England and will come to them at the age of 19? Dawn will find Andrew when she studing in London and be engagede to him. Oh and Hammond from stargate is Buffy's neighbore and knows about the supernatural. I thing it's a series but I don't know for sure.
So please who help me find this story or stories if it's a series.
