Preparing the perilous Castrovalva journey

The Doctor, still weakened and struggling with lucidity following his regeneration, is wheeled by Nyssa to discuss their desperate escape plan. Nyssa outlines Castrovalva as a remote Andromedan refuge where the Doctor might recover, emphasizing the planet's suitability despite the long journey ahead. The Doctor raises urgent concerns about Tegan's ability to manually set the TARDIS coordinates under the ship's unstable conditions, highlighting the precariousness of their plan. Nyssa stands firm in her belief in Tegan's preparation while acknowledging the inherent uncertainties of manual piloting, setting the stage for an impending crisis in navigation and trust. key_dialogue: [ DOCTOR: Castrovalva.
