7. "I Gave You My Number. I Thought You Might Call. Is That A British Army Browning L9A1 In Your Pocket, Or Are You Just Pleased To See Me?" - Moriarty
Andrew Scott's brilliant portrayal of Moriarty really began in The Great Game. Having taken Watson as a "hostage", Moriarty reveals himself and to Sherlock's shock we find out it's the Jim who Molly introduced Sherlock to. This entire scene is beautifully written and done with it all beginning with this incredibly awesome and quite funny line. He's a terrifying man, and this really rams it home.
