Accepting to lend their trust to Mace and acknowledging him as one of them, the aliens propose that Mace return to their home planet with them. Torn between his desire to be free and his loyalty towards his superiors, Mace first reacts aggressively, killing one of the two aliens, but he eventually realizes the cruelty of his act and feels remorse for showing these harmless visitors what dark instincts inhabit the human nature. It is also implied that the alien that Mace killed was the one whose DNA had been used to modify Mace's anatomy; effectively making him a duplicate of the creature.
