Kamelion, being telepathic, has tapped into Tegan's memories. She wanted to show Turlough the Doctor she first knew, but Kamelion has shown them the first three Doctors, and is overwhelmed by Tegan's childhood memories of her parents and Aunt Vanessa, as well as the Fifth Doctor's memories of Gallifrey. Kamelion sinks his hands into the TARDIS controls, and the TARDIS goes out of control. While he appears as the Third Doctor, the Doctor comes in and assesses the situation. He, Tegan and Turlough run through the corridors, while the Doctor explains on the way that Kamelion has been translating thought transmissions but can't perceive subjective memories. The Doctor finds what he is looking for — a casket in which to put Kamelion, to shield him from their memories.
Later, the Doctor asks Tegan if she is happy.
- Kamelion shows Tegan and Turlough the First, Second and Third Doctors, but is stopped before he can show them the Fourth Doctor.
- Tegan feels like the Doctor and Turlough share a bond that she is not part of, and she misses Nyssa.
- Tegan's mother name is Joy.
