Yay :D So glad to find a fellow appreciator of the thing, I'd never imagine there'd be another person to share both these interests. (May I inquire where you fit in it?:))

Well, I based my assumptions on people I know, so there's a Master who acts exactly like Douglas, two Mermaids who are close to my Arthur-headcanon, and a Guardian who is similar to Carolyn, but not really; but Arthur can make a mistake, can't he?:)

If you've seen House MD, Cameron is an acknowledged Goat, I believe she and Martin are similar in some way.
