· Mawdryn Undead Part 2

First meeting with amnesiac Brigadier

The Doctor lands the TARDIS in a walled garden in 1983, stepping into a role he never expected for his oldest friend. The Brigadier, now teaching at a remote boys' school under an assumed name, greets him without recognition. Their brief encounter reveals a cruel twist of time: the man who once stood shoulder-to-shoulder with the Doctor through decades of alien crises now faces him as a stranger, unaware of their shared past. The weight of this paradox settles instantly, as the Doctor must weigh the urgency of his own mission against the kindness of reaching out to a man who has no memory of him at all. key_dialogue: [ DOCTOR: An undercover operation, is it, Brigadier? I mean, I hardly expected to find you at a boy's school. ]
