This is what I can remember:
Spike saves a little girl (around 4?) from a vampire in an alley. I think the girl makes a comment about 'Spike' being a dog's name and she knows about ''bampires''. She turns out to be Buffy's daughter. They have to protect the girl from Angelus and to keep her safe she can't leave the apartment. The stranged father is human and for some reason he sells/ promises the girl to Angelus. I'm pretty sure that Dawn is engaged and Angelus puts her in the hospital.
The girl loves Spike and wants him to be her daddy. At some point Giles, Xander and Willow are at the apartment.
Any help would be greatly appreciated! |
