Doctor senses trap prior to activation

The Doctor stumbles outside the Zero Room as steam spreads through the corridor, his regeneration barely stabilized and his movements unsteady. Though his companions cannot yet see the full design of the Master’s trap, he detects its approach through a haze of disorientation. Aware that time is collapsing around them, he pushes against Nyssa and Tegan’s attempts to guide him and insists on taking immediate action. His urgency clashes with their protective instincts, but the thickening vapor and the TARDIS’s erratic lurch confirm his instinct that the trap is tightening—and that delay could seal their fate in an instant. key_dialogue: [ DOCTOR: I've got to do something. ]
