Andrew Scott recently reprised the role of Moriarty in the final moments of Series 3’s finale, ‘His Last Vow’.

Moffat told Vulture: “I can’t really say what we’re doing with that, but there is no last-minute whim in this. We’ve had what we’re going to do with Moriarty in place from before the second season. Exactly what we’re going to do. I remember talking it through with Andrew Scott, who plays Moriarty. Wait and see what’s going to happen.”

Discussing the final moments of Series 1 and the the first scene of Series 2’s opener, ‘A Scandal in Belgravia’, he commented: “In just a few minutes, you have the most ridiculous set of events you’ve ever seen in your life. If you just show those two things together to someone and say, ‘This is what Sherlock is like,’ they’d be like, ‘What? What the fuck is this series? What are you all on?'”

Andrew Scott commented recently: “I think it’s very important with Moriarty that you don’t overuse him. I think the reason he’s been a success is because he has a mystery.”
