=== Trelane's parents ===
Towards the end of James T. Kirk's encounter with Trelane in 2267, Trelane's parents revealed themselves, appearing in front of a treetop as little more than indistinct, oddly pulsating, hovering translucent green blobs. They chastised Trelane as he stood in a pool of light pleading with them, and eventually removed him from the surface of Gothos. They spoke in rich, faintly echoing voices.
Most of their conversation was directed at Trelane, but Kirk was right there to hear every word of it. Kirk learned that Trelane was a spoiled child, who had created the planet of Gothos and everything on it for his own enjoyment, and everyone he sent down to Gothos were playmates to him. Trelane's father told him he was "disobedient and cruel." and Trelane's mother told him that if he could not take proper care of his pets, he could not have them at all. His father also told him: "They're beings, Trelane. They have spirit, they're superior." His mother then told Trelane that he'll grow up, and he'll understand. Trelane's arguments descended into childish whining, which drew a sharp rebuke from his father: "Stop that nonsense at once, or you will not be permitted to make any more planets!"
After Trelane left, his parents apologized to Kirk, but his questions - "Who are you?" and "Who is Trelane?" - were unanswered. Instead, Trelane's parents told Kirk he must forgive their child, and the fault was theirs for indulging him too much, and he will be punished. They also said they would not have allowed Trelane to intercept them, had they known how vulnerable Humans really were, and they promised to maintain the planet's life support systems until Kirk returned to his ship.
