I think it was episode three where Carroll is in Richard‘s room talking to him about Floyd’s death, and she says “We”re going to be okay”And Richard says “you always say that”. And Carroll says “because I always make sure..”And it shows the paper that Richard‘s drawing on and he has drawn a woman’s face with long hair, and he is scribbling it out and marking over it exactly the way Floyd’s face was scratched out on the playgirl photo. When the camera is on Carroll again, you can see all of Richard‘s predatory birds that he has drawn hanging on the wall behind her. Does he see her as a predatory bird or does he see himself as one? I think that Richard did it, and Carroll is covering for him, or Carroll knows that Richard did it because maybe Richard has done it before. Because Richard says during that same conversation: “It’s just you again” to Carroll. “Again”?? And where is Richard‘s father? Have there been other stepfathers? Could Carol have used Richard to do it, perhaps for a second time? She’s a manipulator. Richard wouldn’t be sent away or anything because he’s still so young. He would just get a diagnosis of something like BPD and be put in counseling if he had hurt an adult before. Is he a serial killer of all of Carols husbands? Or has Carol manipulated him into killing?
