Buffy the Theory Slayer

I found out today that astronomers have discovered a large object half the size of Pluto out there in the Kuiper Belt and have named it Buffy. Because of it's strange orbit, Lynne Allen (one of the researchers) said, "Maybe Buffy is going to be a bit of a theory slayer". Previously another KBO was found and named Xena and it's moon Gabrielle. If it turns out Buffy has a moon will they name it Willow or Xander or Giles or Dawn or Spike or Angel or...?
