Madame Vastra in the style of my silurian design. A Silurian noblewoman (and, functionally, the last of her species) who runs a very successful for-hire detective business in 1800s London with her Human wife Jenny and Sontaran housekeeper Strax. While she is a deeply sensible and learned person who's largely adjusted to life in a human-centric world, she still occasionally falls into the arrogant and dismissive attitudes of Silurian society; the commonalities between her and the Doctor aren't exactly lost on their friends.
(also, yes, the people they work with are just as oblivious to the fact that she is a dinosaur and more scandalized by her gay marriage as they are in the show proper)
