A blind human telepath who served as aide to the Medusan ambassador Kollos, and who used her skill to restore Spock's mind.
Dr. Miranda Jones is a human telepath trained on Vulcan, travelling aboard the Enterprise as aide to the Medusan ambassador Kollos. She hides her blindness with a sensor web woven into her clothing, and she resents Spock, who she believes is better suited than she is to communicate with Kollos.
When Larry Marvick, who loves her, sends the ship beyond the galaxy and then dies, Spock melds with Kollos to navigate home. Afterwards Spock is driven mad by the sight of the Medusan, and Miranda overcomes her jealousy to link with his mind and bring him back. She was played by Diana Muldaur.
