Come to think of it -- did we ever see Meredith handle mountain ash? Has Deaton ever seen Lydia handle mountain ash? Deaton was aware of the Dead Pool but never suggested that Lydia was out of place on that list -- and yet, he thinks nothing supernatural can cross mountain ash. I wonder if they're headed in that direction and they've been hinting at it all along. (To be honest, that's probably more advanced planning than Jeff Davis would ever do.)

I would guess that not all banshees can be made from the Dread Doctors for two reasons -- one, as far as we know they give humans the abilities of supernatural creatures that exist -- even though we haven't seen a lot of these creatures before, nobody's suggested that they're an invention of the Doctors. Also, if banshees were an invention of the Doctors, it makes considerably less sense that Jennifer would have spoken of them in the way that she did when she had Lydia kidnapped.

That said, there's no reason that Lydia and her grandmother couldn't be the result of a successful chimera experiment from years ago.
