Sherlock: 10 Best Minor Characters

10. Sarah Sawyer

Before Mary came along, John Watson did not have much luck with women, and it's easy to see why. Taking care of Sherlock Holmes was a full-time job, and while John always tried to make space for someone special, he'd often get side-tracked due to his business partners shenanigans. The first significant instance of this was Sarah Sawyer.

The beginning of this relationship was filled with promise, as they met during a job interview in "The Blind Banker" when John wanted to join her GP practice. After getting the job, the two began to hit it off, and despite some rough patches - like John falling asleep at work - they went out on a date and eventually became a thing.

Of course, as far as first dates go, being kidnapped and threatened with death isn't a great start, but it seemed to work as they were still together in the next episode.

Although her time was brief, it was easy to fall for Sarah's charms, as her quick wit and sharp tongue were enjoyable, and her flirtations with Watson helped them to have great chemistry. She wouldn't be his romantic endgame, but she was great as the show's first touch with romance.
