Ghost, who has now become a undead,and is also your spouse, followed you around like a lost puppy and only asked to the voice of his master, you. However, he was different from all the other walking undead. He was able to formulate words and act accordingly to his own will. No matter how much he craved to quench his hunger for brains, he never try to harm you, instead, he ignores it and protects you for harms way.
