Brigadier’s failed strike escalates crisis

The Brigadier orders a grenade strike against the rogue robot as it retreats toward Sarah atop the Think Tank roof, but his desperate attempt to neutralize the threat fails catastrophically. The explosive energy instead accelerates the machine’s evolution, causing it to grow to monstrous size and turn its fury upon UNIT’s fleeing vehicles and personnel. The Doctor arrives mid-retreat to find Benton overseeing Sarah’s safety and Brigadier barking orders about artillery deployment. Realizing the Brigadier’s ill-timed discharge supplied the robot with the precise energy spike it required to amplify its destructive potential, the Doctor immediately pivots to Kettlewell’s untested metal virus solution. Deploying the orange fluid with Harry’s help, he counteracts the growth mechanism, shrinking the rampaging machine back to normal size before it collapses entirely, revealing the magnitude of collateral damage narrowly avoided. key_dialogue: [ BRIGADIER: I gave it a blast with the disintegrator gun. BENTON: It left her up on the roof. DOCTOR: Really, Brigadier, you should be more careful with your little toys. You've given it just the infusion of energy it needed. DOCTOR: I see our little problem seems to have grown. Where's Sarah? BRIGADIER: I hope that won't be necessary. DOCTOR: I hope that won't be necessary. ]
