Hmmm okay so XD I would love to have Buffy and the Doctor ~know each other~ or have established CR for the event. I'm going to take her from her future, possibly from the comics if I can canon review enough in time. So that'll make sense for her too.

But also since she lives in the dreamworld she's going to start feeling really weird and like things aren't right, jsyk. lmao whether or not that's relevant to your interests.
