If Murdy really doesn't want to, he'll be harassed into doing it. I'm sure Aiello will leverage the low-blow we always use against Murdy when he doesn't want to do a highly-requested property: "You'll do TitE, but you won't do Killer Klowns or Hill House?" Also, imagine the blowback Murdy would get if Orlando announced Hill House but Murdy was like, "Nah, didn't want to do it because it's not popular enough/not scary enough," (etc.)
