No I don't mean frozen in period. I never got the impression the Jossverse vamps are behind the times in any way, they all of them (and I do include the Master) seem to be very much up-to-date. I meant frozen in terms of their own personal development - they are stuck at the age they died at. I know that in some sense that contradicts the whole point of the stories I personally try to tell but I was using it as a way in to writing the women, who I have big problems writing.

So I was looking for a way to interpret both women as Victorians because that was the period when I am writing them and I don't want them to seem out of time by being either too modern or too old-fashioned.

Having said all of which, yes, Darla does indeed fit more as a Restoration woman than her own lifetime or later. I have a very vague memory of once reading a rather good Darla fic set around then, I don't suppose you know it by any chance? (Of course, if it turns out you wrote one I am going to be very red faced!)
