Doctor probes Brigadier's amnesiac mind

The Doctor crash-lands in 1977 and reunites with his old ally Brigadier Lethbridge-Stewart, now teaching mathematics and gripped by a deep amnesia suppressing decades of shared history. As the Doctor methodically recites names of past companions—Jo Grant, Sarah Jane Smith, Liz Shaw—the Brigadier’s resistance falters, his buried memories stirred by the echoes of voices softly repeating the same names. The Doctor suspects a lingering trauma, possibly induced, and presses for a path back through the mental block while the Brigadier bristles at the suggestion of treatment. Their reunion reveals not just forgotten past battles but the fragile, fracturing trust between them, tested by time’s cruel amnesia and the Brigadier’s stubborn denial of weakness.
