LIZ 79 Air-Conditioning Grille (with Tampered Screw Heads)

Metal grille integrated into the LIZ 79's ventilation system, secured by tampered screw heads that confirm deliberate sabotage. Milo inspects the screw heads and grille amid the ship's suffocating heat and oxygen drain, spotting recent loosening that blocks airflow and vents oxygen. Dom struggles to breathe nearby, his panic amplifying the immediate threat as the grille's blocked state turns the cabin into a death trap, forcing immediate action. The tampering serves as the key clue exposing Caven's betrayal and heightens the crew's desperation, underscoring the saboteur's ruthlessness and propelling Milo and Dom into a race against suffocation while advancing the Doctor's mission.

Milo discovers oxygen sabotage aboard Liz 79

The tampered screw heads of the Liz 79’s air-conditioning grille are the undeniable proof of sabotage, their recent loosening the direct cause of the ship’s suffocating conditions. Milo’s fingers trace their edges, his deduction—‘The airflow. It’s been cut!’—turning these small metal components into the linchpin of the crew’s survival. The screw heads’ state is a tangible manifestation of Caven’s treachery, their tampering a deliberate act of violence against the crew.

Before: Loosened and misaligned, blocking the grille’s airflow and venting oxygen from the cabin.

After: Confirmed as the source of the sabotage, with their tampering now a known threat. The screw heads remain loose, but their exposure may allow for repairs if the crew acts quickly.

Madeleine revives unconscious crewmates

The air-conditioning grille is the physical conduit through which oxygen now flows back into the cabin, its faint hiss the only audible confirmation that the Doctor’s repairs are taking effect. The grille’s role is purely functional in this moment, but its presence is a tangible reminder of the sabotage’s impact and the crew’s vulnerability. Madeleine’s focus on the grille—both as a source of hope and a symbol of the ship’s fragility—highlights the precariousness of their situation.

Before: Tampered with and blocked, contributing to the oxygen drain and the crew’s suffocation.

After: Functional but still part of a larger unstable system; oxygen flows, but the AI remains unresponsive.
