Doctor and Harry infiltrate Thal corridors to spy

The hatch in the Thal corridor's floor serves as the Doctor and Harry's concealed entry point into the corridor. Its triangular shape and bent edges allow swift pivoting to either conceal or reveal their presence, enabling them to time their emergence with the patrol's absence. After their use, the hatch is closed and left undisturbed, marking the boundary between concealment and exposure.

Before: Closed and unnoticed in the corridor floor, serving as access to concealed service tunnels.
After: Closed again after the Doctor and Harry exit, concealing their presence and maintaining the hatch's utilitarian role.

Davros reveals his conquest plan

The triangular floor hatch serves as the Doctor and Harry’s point of ingress into the Thal corridor from the maintenance tunnel, enabling them to infiltrate undetected beneath the feet of a patrolling guard. After their egress, the hatch is resealed, restoring its camouflage and obscuring their entry point from any subsequent observers.

Before: Sealed flush with the corridor floor, bearing slight outward bending from prior forced use and faint scuff marks from recent movement.
After: Reclosed and flush with the floor, indistinguishable from its surroundings except for the newly aligned scuff pattern from their hasty operations.
