Nyssa and Tegan seek a cure for the Doctor

Nyssa and Tegan scour the TARDIS databanks in a desperate attempt to stabilize the Doctor's unstable regeneration. Tegan’s rapid analysis reveals that ambient complexity destabilizes regeneration, pushing them to find an environment with minimal interference. Nyssa’s practical approach aligns with the Doctor’s known preference for simplicity, leading them to Castrovalva as the only viable refuge. The urgency is palpable as they must act before the Doctor’s condition worsens beyond recovery.

Key Dialogue

"TEGAN: All Time Lords regenerate according to this databank. You'd think there'd be something in here about what to do when it goes wrong."
"TEGAN: Ambient complexity is the cause of many of these failures of regeneration. Some real locations are known to have properties similar to Zero environments and, in some cases, are eminently more effective."
"NYSSA: That's it. We need to take him somewhere uncomplicated. Somewhere away from technology."
