Gia Kelly was the super-efficient senior supervisor of the T-Mat system. She discovered that the Moon controls were no longer operational. When it was clear that this was more than just a mechanical breakdown she acted quickly and sensibly and kept her cool. She was more than helpful to the Second Doctor in his effort to stop the Ice Warriors using T-Mat to spread their deadly "Seeds of Death" on Earth.
