Which as I said sounds cliched in the abstract, but what I'm thinking of is a Mary who is cold-blooded and practical but not actually evil, yet through circumstance lands in the role of antagonist anyway. Also something that actually does the whole Final Problem/Empty Hearse story arc properly.
The problem is it would be a WIP. I don't do WIPs - hardly read them, haven't written them in a decade+. I'm not even sure I know how to do them properly, and the scope strikes me as... ambitious, to say the least. Also my creativity seems back but my execution not so much, and I do have at least two other fannish projects I want to polish off.
Still: I have so many delicious ideas here.
Someone talk me out of it, or into it?
