June argues "Ultivac is a scientific marvel". The robot swims out. Ashore, Red shoots while Rocky attaches a magnetic bomb that destroys Ultivac. Not. Ultivac sent out a decoy. June convinces him "Wars never solve anything!" and Ultivac agrees to a televised public hearing, and pledges to help humanity. Hesse blasts Ultivac and Rocky - who dies on the operating table, as foretold. June offers to take Rocky's place, and the Challs agree, until Rocky miraculously revives. Ultivac ends up a stationary calculating machine, his spark gone, yet "still contributing to man's knowledge".
