 Back in the spaceship, Chouns, who is known for his 'hunches', eventually realizes what's happened; that they've been telepathically 'conditioned' to transfer pollen from the plants (who are the real masters) on one planet to the other.The telepathic control of the plants coerced them into doing this by making them believe that two small rocks were actually valuable and that there would be more on the other planet.Chouns believes that he must immediately warn Earth of this threat, as he also realizes that one of the two animal species must have at one time been capable of interplanetary travel.
