Turlough secretly overrides TARDIS controls

After the Doctor returns Brigadier Lethbridge-Stewart to his proper time, the companions drift away leaving Turlough alone in the console room.

The moment underscores Turlough’s unresolved compulsion under the Black Guardian’s control and foreshadows a deeper betrayal that looms over the crew’s fragile unity. key_dialogue: []

The Doctor’s TARDIS

The TARDIS reacts subtly to Turlough’s meddling, its console flickering with erratic energy as the navigational commands are rerouted.
