Temple also recorded a case where a Sentinelese apparently drifted off to the Onge and fraternized with them over the course of two years. When Temple and Portman accompanied him to the tribe and attempted to establish friendly contact, they did not recognize the individual and responded aggressively by shooting arrows at the group. The man refused to remain on the island. Portman cast doubt on the exact time span the Sentinelese spent with the Onge, and believed that he had probably been raised by the Onge since childhood.
