Buffy the vampire?

Prologue

The Scoobies stared at the unconscious human lying on the living room floor. Dawn had tears rolling down her face, everyone else gasped and their mouths dropped open.

"We should call Buffy." Giles claimed walking into the kitchen to call the Slayer. He came back minutes later holding the Slayer's cell, "she left it on the table."

"Maybe one of us should go find her?" suggested Willow.

"Good idea, I'll go." Xander said grabbing his coat and then left for the cemeteries.
