He was George Barclay's American history professor when George was at college. Years later, when George came to Washington D.C. with his daughter Donna, Caroll and George were reunited and recognized each other immediately.
At the time, Donna — who was under the impression that her parents were getting a divorce — mistakenly thought Caroll was a woman, and called Caroll a “homewrecker.” However, much to her surprise, Caroll was actually a man. When George asked Donna if she thought Caroll was a woman, she admitted she did, and explained that a woman had called earlier; Caroll replied that the woman who had called must’ve been his wife. Donna was confused, and asked George if it was true he wasn’t seeing another woman, and George told Donna that he wasn’t. Donna then apologized for what she did.
He has a wife (whose name is never mentioned).
