When Mark returned to the lighthouse from the dead, Charles kept emphasizing that the current Mark was not a human being, and at his urging Victor almost took Mark away to dispose of him. The only way for Mark to live when he took power was for him to travel far away, and told Wren Bing that only one of Mark's dignity and life could be taken away.
