DR (loudly): Just step this way, Mr Cameron. (quietly, to nurse) That bit of paper's got him distracted, but we need to be quick. When we get around the corner, I'll grab him, and you get the needle in. He's usually placid, and a bit slow working out what is going on, but he's a big lad. Got a history of violence and destruction going back years as well. Smashed up few a restaurants.
