The invisible security grid locks the secondary control chamber, forming a lethal barrier that prevents escape. Its shimmering edge is tangibly felt by the Doctor, and Harry’s desperate shouts are silenced upon contact with its unyielding surface.
The extending aerial extends from the Doctor’s toolset to position the hat at an optimal testing distance from the security grid. It operates with precise mechanical whir before the hat attached to it is severed by the grid’s lethal efficiency.
The Doctor holds the hat on the extending aerial, using it as a probe to test the station’s defensive grid. The hat remains intact briefly before being vaporized by the invisible security system, confirming the grid’s lethal configuration.
