Dr. Cecil Pritchfield is a child psychologist in "Send in Stewie, Please" who meets with Stewie after he pushes a boy down the stairs in school.
Stewie makes uncomfortable small talk until Dr. Prichfield notes that he has strong opinions. Stewie brings up his accent, although the doctor fails to take note of it. Stewie analyzes Prichfield's gay relationship until the doctor observes that he is lonely, which brings Stewie to tears. He admits that he is something of an outcast at the school. The conversation changes to Stewie's sexuality, which he claims to be heterosexual and admits plucking his hair, his fling with world domination and his fascination with musicals.
He takes up an offer of tea and the Dr. tells of his own youth in the blitz where he lost his parents and was passed around until he ended up in an orphanage. Stewie stops his long story and they return to Stewie's differences and he slowly drops his accent. He considers allowing his true self out but reconsiders returns back to his old ways. As he starts to take a sip of coffee, the Dr. begins to have heart trouble and Stewie allows him to die since he's seen the truth behind the facade that Stewie puts up.
Dr. Pritchfield is voiced by Ian McKellen.
He is seen in a hallucination of Peter's on a cruise ship full of deceased characters in the Panama Canal in "Coma Guy".
