Doctor and Turlough salvage Tardis plan

The Doctor confirms the Tardis is aboard the alien ship after realizing the entity in the capsule had used it to flee. With the transmat transmitter destroyed, their original recovery plan is impossible. The Brigadier suggests the younger brigadier may have the homing device, prompting a shift in strategy. The Doctor seizes on this using the device to locate the Tardis directly, demonstrating his adaptability amid the unstable regeneration and deepening the uncertain alliance with Turlough as they pivot from failure to improvisation. key_dialogue: [ DOCTOR: It must be on the ship.
