Master’s betrayal after Doctor’s mercy

Jo and the Doctor believe themselves dead in an empty void before encountering Kronos, the cosmic entity they freed. The Doctor’s plea for the Master’s life spares him—only for the vengeful renegade to snatch the crystal, betray his savior, and flee in his TARDIS, leaving the Doctor and Jo stranded. The moment crystallizes the tragic irony of kindness misplaced and the unbridgeable gulf between the Doctor’s compassion and the Master’s unrelenting malice.
