Around and following the events of "The Reichenbach Fall" (BBC, 15th January 2012), Molly writes the following letter to Sherlock.
You don't see me.
It's not that you don't care, it's that I don't count. I'm nobody. The only time you come to me is when you need me, when no one else will do.
It's usually a disaster, so I shouldn't feel glad when that happens. I do, though. Of course I do. That's when you notice me, and that's when I can be helpful to the man who knows everything and sees everything and can do ... everything.
You never try to be rude. I do tell myself that - you're the same to everyone, you just don't see the point in politeness and diplomacy. But at the same time it hurts because you're always thinking about yourself. Me me me! I'm greater, I'm clever, and you're ordinary!
And then you told me that you weren't who I thought you were, nor were you who you had always thought you were.
I don't believe that yet.
If you were ordinary, you wouldn't have come to me, because you wouldn't have known you needed to. Even if you had, you would not have known what to do. But you had that brain, the one that saw not only the problems but the solutions too, and you came to me.
You will never be ordinary, Sherlock. You are extraordinary, and no matter what they say, you always will be.
