Doctor stops Turlough from stealing TARDIS

With the ship’s transmat destabilized and time fraying around them, the Doctor abandons the relative safety of the sickbay to prevent Turlough from triggering a catastrophic return to the TARDIS before repairs are complete. His unstable new form heightens every risk—one misstep with the controls could strand them forever in a time loop or strand the Doctor’s own incipient regeneration. The urgency mounts as he discovers the Guardian’s malevolent influence lingering in the capsule’s components, forcing him to act before Turlough’s latent manipulation becomes irreversible. key_dialogue: [ DOCTOR: Now. Come on. We've got to get back to the capsule before Turlough works out how to operate it, or I may never get the Tardis back. ]

"The Doctor's interrogation of the Brigadier in 1983 about the 1977 incident (beat_0aaef1f2c4eac6f2) directly leads to the Brigadier handing over the homing device in a later scene (beat_8c3d79ea9297c39a). This device becomes the key to locating the Tardis, showing how the initial questioning sets up a crucial plot development."

"The Brigadier's distress and memory lapses (beat_8ed0bdd5c880f047) are directly tied to the explanation of the Blinovitch limitation effect (beat_a45eeecb354ecdde). His past experiences with the Doctor and the Brigadier's awareness of his own instability create a psychological link that drives his caution."
