Williams prepares his personal scout ship, with the Doctor and the Prince accompanying and heads at maximum speed to the coordinates the Doctor took from the Master's ship. Jo manages to dig her way into the next, unlocked cell and sneak further into the bunker as Williams's ship enters orbit. She pockets the hypnosound, then finds a pad with the coordinates of the planet and bunker on it and transmits a distress signal with the information. The Master shows up, revealing that the signal was muted, and the only person who could have picked it up was the Doctor, whose ship he detected in orbit around the planet. When the Doctor comes, the trap will be sprung.
