Master reveals weapon’s blackmail potential

The Master’s gas mask is a critical piece of equipment that enables his escape. He secures it over his face just moments before deploying the gas grenade, ensuring his immunity to the fumes. The mask’s straps dig into his skin as he moves, a physical reminder of his preparedness and the lengths he is willing to go to survive. It also underscores the asymmetry of power between him and the Doctor, who is left vulnerable to the gas and forced to hold his breath. The mask’s presence is a silent but potent symbol of the Master’s cunning and his advantage in their ongoing rivalry.
