Waldo Butters is the undertaker and doctor for relinquish. He had a very keen interest in helping people when he was a child. He learned how to be a doctor when the doctor they had at the bunker was getting old, he decided to apprentice Butters. When the undertaker died, Waldo immediately asked to be taught how to do that instead. Butters prefers dead people saying "They don't bleed and hurt if you have to do something painful to help them."
