You let me in. You wanted me, partner. So you think you can use your little tricks to banish me again, like that? No. I do believe I’ve got you, bunk buddy. Got my finger wiggling around in your brainpan. 

I am the soul that never dies when flesh is weak.

All those times you ran away…you weren’t running from them. You were running towards me.

Oh, he’s absolutely on his radar. Moriarty has an obsession with Sherlock, but that means the detective’s best friend is always going to cause some sort of stirring of strong emotions. There’s a scene in the final episode where I wanted to be able to show that in a small way what Moriarty’s attitude to John is. I think it’s one of restrained respect, but also one of envy. Because Moriarty is a sociopath, I think there is something he doesn’t fully understand about friendship. He doesn’t have any friends himself, and that’s what separates him from Sherlock.

This is how I show my love.

Look at them. They all care so much. Do you ever wonder if there’s something wrong with us?

James Moriarty isn’t a man at all. He’s a spider.

Staying alive…it’s so boring, isn’t it? It’s just…staying. All my life I’ve been searching for distractions. You were the best distraction, and now I don’t even have you. Because I’ve beat you. And you know what? It was easy. It was easy. 

Andrew Scott became a star - which he absolutely deserves to be - on the basis of being in the last three or four minutes of Sherlock. His screen-time was tiny but it’s a measure of that man’s extraordinary talent that he’s become such a big deal so quickly. He’s a genius. -Steven Moffat (x)
