Brigadiers recognize each other through touch

The two versions of the Brigadier stand face to face in the laboratory, decades apart yet bound by the same past. Confusion and hostility give way to recognition as the 1977 version repeats his challenge, his tone shifting from disbelief to dawning understanding. The 1983 Brigadier answers simply that he remembers, creating an instant of temporal recognition that bridges their fractured timelines. Their hands meet in a fleeting touch, unleashing a blinding flash. This physical connection resolves the paradox forced by the Black Guardian’s manipulations, altering the destinies of both men and the companions who depend on them.
