In one story in the 1970s, it was revealed that Mr. Doiley is actually Dilton's stepfather. None of Dilton's friends know this except for Chuck Clayton. Dilton, not feeling that he could deal with the shock after it being kept a secret all this time, almost ran away from home. However, after confiding in Chuck about his problem, Chuck made Dilton realize that Mr. Doiley cares about Dilton like a real father and that he would be heartbroken if Dilton ran away from home.
