Why is Sherlock wearing John’s jumper?
An excellent question. My theory is that the Amy of the title is actually Molly Hooper’s evil twin. She takes over her sister’s life, party dress and morgue and builds herself a dream man from any stray bits she can lay her conniving hands on: Sherlock’s head, John’s knitwear, the left arm of Chiwetel Ejiofor and goodness knows what else. Molly has to fight to regain control of her life, reassemble all the men in it and move that vase of tulips away from the fireplace before they wilt.
Meanwhile, in the bottom right hand corner, Helen Hunt watches Tony Danza’s unsuccessful screen test for the role of Max Headroom, and smiles.
