Jane Watson (Jane and Sherlock)

Jane Hannah Watson, mostly referred to as Jane H. Watson, is the narrator and one of the two protagonists of the Jane and Sherlock series. She is an ex-army doctor who is the flatmate and female companion (later wife) of Sherlock Holmes and portrayed by actress Lucy Fry.

Like John, Jane is an ex-army doctor who returned to England with a wound to the shoulder and a lame leg. She has a sister she doesn't get along with and her mother resented but supported Jane's decision to become a doctor. One day walking through the park, she comes across lifelong friends, Michael Stamford, who introduced her to famed detective, Sherlock Holmes. Though not a fan of women, Sherlock was reluctant to allow Jane to say at his flat, but invites her anyways.

However, the two of them fall in love, and eventually marry each other at the end of season three.
