Nyssa and Tegan pace a ruined TARDIS corridor

Nyssa and Tegan leave Adric behind in the corridor as they continue exploring the deteriorating sections of the TARDIS. Finding a waistcoat discarded on a packing case labeled Handle with Care, they comment on the ship’s seemingly endless depths and the sense of descending into forgotten, unused regions. Their observations hint at the severity of the TARDIS’s decay while underscoring the urgency of their situation: time is slipping away as the Doctor regains control from his forced regeneration and the Master’s trap tightens around them. key_dialogue: [ TEGAN: No, that looks like the end of the trail. NYSSA: This part of the Tardis can't have been used for centuries. TEGAN: It does go on and on. NYSSA: Deeper and deeper. TEGAN: Yes, I get that feeling too, that we're going downwards. ]
