FIX YOU
When Joan Watson first heard of Sherlock Holmes, she was under the impression that she would be helping him. He was a drug addict. She was a sober companion. Well, she was, for however long a length of time. So, it was her job to keep him on track with his recovery and make sure he wouldn't relapse.
However, in the long run, Joan often found herself fighting to stay on track with him.
Sherlock's sobriety was a fact to him. He had simply stopped using. Even while Sherlock showed an extremely low desire to return to his addiction, Joan still remained firm in showing him that while the meetings were boring and 'useless' to Sherlock, that there was more to the world around him. Sherlock's world had ceased to have a population of one, but had now become two, with the exception of a few others.
And while Sherlock had shown significant progress in many areas of his life, even mentioning on the rare occasion that Joan, "made him better," John found that it was no longer as simple as that.
Joan was no longer his sober companion. At least not legally, but she had become more than a companion. She was a partner. Sherlock's partner.
The idea of romance was beyond them both. They were friends, at least in Joan's mind, but they were also fairly respectful and remained professional. At least most of the time, anyway.
And as she continued to hone her own talents and fight her own battles, a fact slowly began to grow startlingly clear.
Joan Watson had not fixed Sherlock Holmes. She would never be done 'fixing' the strange and unique man. But again, it was no longer as simple as her 'making him better.'
They were fixing each other. With every case from the NYPD, Joan was the steady and silent reminder of Sherlock's humanity. This showed in the way he slowly learned to avoid belittling others and even going out of his way on the rare occasion to praise the good work of others he cared about.
Sherlock, in turn, was Joan's guide to discovering herself. He showed her to herself like a mirror, explaining the tiny and once insignificant details into a form that showed Joan there was far more to herself than what she claimed to be. He showed her there was more than the confinement she had built for herself.
Likewise, she did the same for him.
And in the end, it didn't really matter to Joan who fixed who. That wasn't the point.
The point was that they were better for it. They were stronger now. Even though they often faced monstrous challenges and impossible situations, they pulled each other through.
They would find their own way home. And they would continue to grow and shape their lives, smoothing out the rough edges of each other as they'd always done.
And they'd continue to fix each other. As they'd always done.
