Sherlock?

Yes, John?

You told Moriarty that you didn't have a heart

That you'd been reliably informed you didn't have one.

So who told you?

You should know, John.

I only trust one person enough to be told that.

I told myself.

But I've seen how you care for me, and Mrs. Hudson. You must have one.

I used to. It was stolen, though.

Who took it?

Someone who hasn't returned it since.

Who is it, Sherlock? They hurt you, didn't they?

Well, I assumed they knew they had it.

They were the most special person to me.

I had to leave for a while, though,

And when I came back, I thought they hated me.

They moved on, found someone else.

. . . . Oh.

It's okay, John. You didn't know.

I should have.
