James was a doctor for a small mountain community. He lived alone, due to his super mutant nature, but always did his best to care for the people in his small village. He studied pre-War medical journals and tried to perform as much modern medical care as possible, as compared to a tribal shaman.
While on a house-call to one of the village elders, a storm snowed him and the patient in. When the rest of the village was able to reach them months later, they discovered one fairly fit super mutant and the bones of the village elder.
The villagers turned James over to the NCR for practicing medicine without a license, but they were never able to prove the charge of cannibalism. James refuses discuss the events of those months.
