Yeah, and last night I just got an idea for a continuation hereof; what if since there's a rumor that Buffy herself as a vampire slayer is part demon (something she's long been scared of by the way), she gets harmed by some ghost who detects the essence of the slayer, the demonic essence, that is, and destroys that spirit; so her friends seem to have to give her medical attention, as she's left a wreck while escorting him home as a sequel to this?
There's something to think about- as one human monster realized, 'an assassin determined to risk his own life to accomplish his mission is almost unstoppable'. a paraphrasing of one of a certain A. Hitler's discoveries.
What if a hitsquad of ghosts are willing to risk their own existence to get rid of her as she's part demon, or they think she is? Perhaps the First played a mind-game on the ghosts and got them to try and murder the slayer essence. That's one possible scenario for this to go down.
Would you mind if I were to write such a story? You've inspired me in that regard.
Sincerely one of your hopefully many fans;
Vantiri.
