Yes, and I'm really sorry it's taken me so long to reply - I got a bit stuck when it comes to character ideas, I think! Brock, while it'd be fun, is probably too minor a character in the grand scheme of things. I'm not sure I'd really be able to do justice to some of the more well-known characters though, so I'm thinking that it might be easiest / best to make an OC that'd fit in with the Fables style of things.

I've had an idea about the Cheshire Cat of Wonderland floating in my head all weekend, you see.
