The rescue party brings Rollason back to the monastery where Rollason asserts to the Lama that the expedition found proof that nothing exists regarding the "myth" of the Yeti. Perhaps Rollanson is keeping the secret of Yeti existence because he feels it is the only way to protect the Yeti race. Or, perhaps Rollanson is still under telepathic control by the Yetis. Or perhaps Rollanson fears that the Lama might kill him and his wife to ensure the ongoing secret of the Yeti people. The uncertainty of Rollanson's motivation makes a terrific ending to the film.
