John, Carol and Kenny mount an operation to rescue the kidnapped Stephen. They take him to their Lab, based in a disused part of the London Underground train system, and introduce him to TIM, their biotropic sentient computer. Stephen is still under Jedikiah�s control, and, left alone in the Lab, he deactivates TIM's external connections and opens the door to allow Jedikiah, Ginge and Lefty to enter.
