Benedict Cumberbatch and Mark Gatiss on Andrew Scott

• Mark: [T]there are moments in it which are so scary and [Andrew's] face becomes a sort of lizard like set-mask, and this real evil just comes through. I think it's really remarkable.
• Benedict: Oh marry him.
• Mark: Oh, I am.
• Benedict: You're going to marry him?
• Mark: Yeah, that's a given. Yep.
• ....
• Benedict: The extrodinary thing is that because he's such an archvillain there's a real attraction to him, but at the same time it doesn't diminish Holmes' being his perfect foe. It's a very good match between the two of them.
• Mark: Well, you have to marry him now.
• Benedict: I do, don't I?
