Doctor scuttles TARDIS to generate thrust

The Doctor, weakened by his regeneration but forcing clarity, directs Nyssa and Tegan in a perilous plan to manually reconfigure the TARDIS. With the time ship stranded and systems failing, he orders the deletion of entire rooms to generate thrust, gambling everything on an untested fix. Nyssa manipulates a critical lever while Tegan records his instructions, their trust tested as the Doctor’s hands suffer burns from the overloaded console. This moment demands precision under pressure as the companions execute a scheme that could either free them or doom them permanently.

Key Dialogue

"DOCTOR: The whole system is on manual now. This is where it starts to get really dangerous."
"TEGAN: Don't worry, Doctor. We'll get you straight back to the Zero Room."
"DOCTOR: The architectural configuration system can do more than that. We can actually delete rooms."
"TEGAN: Delete them? You mean zap?"
"DOCTOR: Yes, exactly. Zap! Enough zap and you have your thrust. Now, follow this very carefully."
