you have to admit he is pretty much spinning the wheels with this storyline and has been inserting random characters in no particular order one after another in Bruce's "knightmares" or do you see a order in this sequence of Knight mares? by logic Nightmares are a mix of memories and other random information played out in a super disturbing way so these knightmares must also fall in those category. kings work involves mostly dwelling on trauma and so naturally the stories must have a random element to them so as to enable to impart a sense of anything can happen which could indicate anything and be open to any interpretation so it does come off as events occurring randomly in Bruce's mind as he concocts various nightmares from his subconscious unless you feel that Tom thinks Bruce's knightmares are ordered logical explorations of his subconscious.
