Who Was There
Characters present in this moment
Fragile clarity masking the threat of collapse
The Doctor shuffles between his companions, his body light as paper but his thoughts razor-sharp. Although his skull still bleeds and his breath comes shallow, he names the deceit—Castrovalva’s self-collapsing streets—transforming shock into sagacity.
- • Identify Castrovalva’s spatial trap before it seals shut
- • Stay conscious long enough to reach sanctuary
- • Understanding the enemy’s design is the first step toward escape
- • His companions’ strength will buy the time his body cannot
Focused resolve masking underlying fear
Nyssa braces the Doctor’s slack body against her shoulder, shouting directions to Tegan while scanning the corridor for omens of collapse. Her analytical mind races in lockstep with the physical danger, and her urgency to reach the Zero Cabinet overrides any hesitation.
- • Diagnose and neutralize the spatial disturbance threatening the Doctor
- • Return the Doctor to the Zero Cabinet for safety
- • The Doctor’s survival depends on reaching the Zero Cabinet before Castrovalva fully collapses
- • Her training in physics grants her insights no ordinary person possesses
Bluntly determined despite escalating anxiety
Tegan hustles alongside Nyssa, hauling the Doctor’s arm over her shoulders while barking the location of his room. The Earth-bound logic of ‘find a safe room now’ aligns perfectly with Nyssa’s urgency, driving them forward despite the corridor’s threatening tilt.
- • Get the Doctor under roof and out of the shifting streets immediately
- • Support Nyssa’s medical instincts without question
- • The Doctor’s medical needs are absolute priority over abstract considerations
- • Following Nyssa’s lead is the fastest path to safety

Places and their significance in this event
The Doctor’s Chamber stands as the final sanctuary in Castrovalva’s death grip, its modest quarters suddenly the only solid bastion amid the town’s collapsing geometry. The flickering oil lamp casts shadows that briefly swallow hope, and the cot’s thin mattress awaits the barely conscious Time Lord.
The Zero Room Exterior Corridor convulses around them as Castrovalva’s self-erasing streets hurl subtle threats—tilting floors, distant creaks, and bursts of hot air from overtaxed vents. This liminal passage has become a gauntlet where every step risks permanent entrapment.
