Doctor triggers gas explosion and capture

The Doctor’s attempt to uncover the truth behind the war’s grotesque facade leads to disaster when his investigation of a locked door triggers a Kaled gas shell explosion. As the poison gas forces the trio to scavenge respirators from corpses, they are ambushed by enemy soldiers. The Doctor and Harry are swiftly overpowered and dragged through the door into the bunker, leaving Sarah stranded and alone in the trench. The sudden explosion and capture force the Doctor to abandon his mission of exploration and instead confront the horrors of Skaro from within—shifting the dynamic from discovery to survival as their plans collapse under enemy fire. key_dialogue: [ DOCTOR: It's a gas shell!
