@IAmNotAFishIAmAFreeMan yeah i suppose you’re right, I just thought we’d find out that someone, or something, was following the Doctor. The chalk falling on the floor, someone writing “Listen” on the blackboard, whoever was outside Orsons space ship/time machine at the end of the universe. I just thought it was going to be pointing toward something in the finale. Maybe you’re right… or maybe it will be cleared up in the Christmas episode. Maybe 😉
