And he just has to keep trying to get 5he food it will stop soon but it doesn't stop until he is sent back to the underworld. Now maybe that's true or maybe an intelligent psychotic individual decided to fuck w him. And what intelligent psycho was around him all the time? Mr.D!!!! That man is a God who used to be a demigod. He refuses to let others have an over inflated ego around him that's why he refuses to use the campers correct names. The only time we see him doing it is when percy showed that he was not going to let his power corrupt him. You think Mr.D was going to let that egomaniac free from any punishment. Using the wrong name wouldn't do anything to him he came from the tortures of Tartarus and still believed he was in the right but continuing his original punishment when he had hope it was removed that is something he would have done.
