Its a goofy little reference this one, but when Angel first arrives in Sandford, hes told his cottage isnt ready so he has to take up residence in The Swan Hotel, ran by Joyce Cooper, and he attempts to check in. Mrs. Cooper replies with check in? But youve always been here creeping the sergeant out before she realises that hes not her husband. Its not an innocent mistake, and Wright really was channelling Kubrick the line is a spin on Delbert Gradys announcement to Jack Torrance in The Shining that hes always been the caretaker. According to the DVD commentary, the idea of the sequence was to get the creepy village jokes out of the way to set up the grounding for the twist.
