Great stuff, our early history is full of explorers becoming enamored with native ways, often marrying into tribes by convincing the chief his daughter would do well with a foreign man. No doubt this required earning respect of the elders in a tribe, and perhaps animosity from the younger men of the community. American Indian lore is full of stories of cannibalism, that one becomes stronger eating the heart and flesh of his enemies. Easily believed, this could have been Brule's fate. On a side note, the word 'vegetarian' sometimes is translated as Indian for 'poor hunter.' This has yet to be established historically, but seems as believable as some of the other fables about native Americans.
