That would be a great back up. Buffy can be the big bad of the entire series. Then, if it suddenly gets cancelled, all they need is a death bite scene and the series has a proper ending 😀She would also probably try and eat the new Slayer, which might result in a very short series!
Unless VampBuffy is the S1 Big Bad.
That'd work too!!I disagree, I think, sort of.
To end the series it would only need an effective use of Mr. Pointy (no disrespect intended).
