Daleks execute Controller install new one

The Daleks turn on their human Controller after his failure to recapture the Doctor, executing him in front of his subordinates as an example of absolute brutality. They immediately promote the Guard to replace him, reinforcing their demand for unquestioning obedience. This purge signals the Daleks' ruthless consolidation of power and shifts the control room's regime, severing the Doctor's fragile alliance with the previous regime. The moment accelerates the timeline toward the assassination of Sir Reginald Styles, threatening to erase the peace conference from history and plunge humanity into war to ensure the Daleks' future dominance.
