S13E15 · The Android Invasion Part 3

Deadly trap lures fumble-fingered android guard

The Doctor and Sarah exploit the brig’s controls to rig a lethal counter. Working under the Kraals’ noses, Sarah baits the electrified plate while their android captor Adams is casually lured into stepping onto it. Meanwhile Harry’s arrival forces an abrupt plan shift: the Doctor is yanked away just as the trap is armed, leaving Sarah to ignite the shock before any alarm can sound. Their fractured timing forces the Kraals into a brutal bind—respond to the jolt and risk betraying their own android forces or press on and lose their prize captives. key_dialogue: [ DOCTOR: Yes, I think this has possibilities. HARRY: Food and drink. DOCTOR: Careful! You androids don't know your own strength. DOCTOR: Don't worry, Sarah. And don't waste the water. Remember, it's an excellent conductor. ]
