Brigadier voices limbo fears

The 1983 Brigadier raises his voice against the plan to separate himself from his displaced past self, fearing invisible damage from years adrift in temporal limbo. His outburst forces the Doctor to confront the personal cost exacted by the crew's paradoxical predicaments. When Turlough's reckless dash through the TARDIS decks jars the ship, the Doctor halts the separation scheme to assess new threats. The Brigadier's anxiety becomes the emotional lens through which time itself feels like a merciless labyrinth.
