Brigadier discovers Parker’s alien-induced assault

The Brigadier, responding to an unspecified disturbance, arrives at the Space Centre Fuel Bay to find Parker—UNIT’s security guard—staggering to his feet, visibly battered and disoriented. Parker’s erratic state and the steam pouring from a ruptured pipe suggest a violent confrontation has just occurred. When the Brigadier demands an explanation, Parker reveals that a mechanic (later implied to be alien-possessed) attacked him unprovoked and fled into the fuel bay. The scene underscores the escalating alien infiltration within UNIT’s ranks, forcing the Brigadier to confront the possibility that even trusted personnel may be compromised. This moment serves as a critical turning point, shifting the narrative from bureaucratic tension to immediate, physical threat—one that demands UNIT’s full attention and the Doctor’s intervention.
