Growth Pains

After Aaron successfully removes a steel rod driven into a man's head in a workplace explosion, the patient miraculously suffers no motor or cognitive problems, but begins to exhibit severe personality changes that greatly upset his family and employees; when a patient in danger of dying from an intestinal obstruction caused by his habit of eating the hair he compulsively pulls from his head refuses the surgery that will save his life, Ray's unorthodox approach to treating the patient's underlying psychological disorder -- by getting Camille to assume the persona of Dorothy Gale from ""The Wizard of Oz"" and role play with the patient -- gets him fired, even though the treatment is ultimately successful; Alan's worst fears come to light when Alicia suffers heart failure, and he lashes out at Jeffrey in his anguish.
