It seems they're doing the Time Warp twist (another one!) the week they know he'll be up (with Simon) and people won't resist the chance to unleash him on some ex-housemates in a secret room (another one) where he'll no doubt get access to a 24/7 feed (like everyone does apart from the viewers). We all know the popularity of HMs goes up when they become the focus of attention in this way, so congrats to the Producer's Pet.
