Soulmate AU, where your soulmate’s name appears on your scalp - Mrs Watson had a problem. The name on her baby John's head was male. With a homophobic Army captain for a father, that just wouldn't do. So Mrs Watson lets John's hair grow in and tells her on duty husband that John's soulmate is called Mary. John grows up looking for his Mary and he think he finds her at uni, in the Lovely Mary Morstan who is training to be a nurse at Barts.
