I think they used the woman that plays the female psycho killer in "Luther" as a model for the thief. see banner image above. And what the heck is up with a woman, then a man going into an outhouse and only one emerging?! I am bored with nothing to do in the pirate game.
Everytime I see the Thief and Priestess I think of Anne Bonny and Max. I'm sure they both go into the outhouse often. #BlackSails
Well for now she is still on the bench/outhouse, until further notice (read: until the release of the patch)
