In the movie, when Jen starts screaming and everyone goes upstairs to find her, when she scares Sarah and they both start sceaming, it cuts to the shot of the kids in the computer room and a guy in red tells him to turn the volume down. A few minutes later, after the mannequin falls on Sarah in the closet, the same guy enters the computer room and sits down next to Miles and asks what they were watching, like he was never in there before.
