Doctor rebuffed by amnesiac Brigadier

The Doctor crash-lands in 1977 and seeks out his old friend Brigadier Lethbridge-Stewart, hoping their reunion will spark long-buried memories of their shared adventures. Instead, the Brigadier greets him with polite confusion, his advanced age and memory loss erasing decades of history between them. The Doctor’s forced smile masks the weight of recognition lost, while the Brigadier’s dismissal underscores the fragility of time itself. This fleeting, failed reunion cements the Doctor’s isolation, revealing the emotional toll of a life spent traversing time without anchoring relationships to claim as home. key_dialogue: [ BRIGADIER: Well, I'm sorry. If we have met before, it's entirely slipped my memory, and I've got to get these boys back to school. Come on, you two. ]
