TARDIS Laboratory Natural Gas Cylinders

Artificially sourced natural gas cylinders used exclusively in the TARDIS laboratory for controlled scientific experiments. Their purpose is to react with the seaweed sample to reveal its toxic properties, with no harmful effects on humans. Distinct from the seaweed-colony-produced toxic gas weaponized by infected humans.

Seaweed’s lethal sentience confirmed

The two cylinders of natural gas are used by the Doctor to expose the seaweed sample to a controlled environment, testing its reactions. While not directly interactive in the dialogue, their presence is critical to the experiment’s setup. The gas fuels Victoria’s Bunsen burner, which in turn reveals the weed’s toxic emissions. The cylinders represent the team’s reliance on scientific tools to uncover truths, even as those truths become increasingly ominous. Their role is functional but foundational, enabling the discoveries that drive the scene’s tension.

Before: Filled with natural gas and placed beside the glass tank, ready for the Doctor’s experiment.

After: Partially depleted after being used to fuel the Bunsen burner, but their purpose is fulfilled. The gas’s role in revealing the weed’s toxicity is now complete.
