Looking for a fic where all the potentials have been activated. Giles is possessed and he beats Andrew up really bad but the potentials leave and take Andrew with them when they go to buffy. Either buffy lost the baby do to poison or is pregnant but it's spikes and she makes a plan to take back the council from giles. I don't know if spike is a ghost or already back from the dead but him and buffy end up together in the end with a baby.
