Isolation Room Bulkhead

The reinforced bulkhead demarcates the Isolation Room from the ship’s corridors, its metal panels cold to the touch and marked with emergency-restraint rivets. When Professor Lasky exits masked, the interaction heightens the bulkhead’s role as both barrier and witness: the Doctor’s demand for explanation implies forbidden access, while Mel notes its plain surface offers no concealment but enforces the room’s quarantine. The bulkhead’s solid thud on latching underscores the risks of surveillance and containment aboard the derelict ship.
