Joan has been working the last 6 years as a detective, and has undergone a lot of training to notice things about people. She has a good grasp of people's mood and whether or not they're trying to hide something, and most often than not blurts out observations about people. So please let me know if you want to play this up or opt out of it entirely, and let me know in the comments anything you would like for me to observe about your character from a starting point!
