This challenge popped into my head almost as soon Amber Bensen appeared on screen in the SUPERNATURAL episode "Bloodlust."
Write a story in which Lenore (the vampire Amber Bensen played in "Bloodlust") somehow meets the characters from BTVS or ANGEL.
It wasn't specified how old Lenore was but, from some of the things she said and the fact that she was leader of a vampire "family," I'm thinking she was pretty old. So, what if Lenore had a child when she was still human, and Tara was one of her descendants?
The story can take place before or after Tara's death.
