Doctor sabotages the gas formula

The bucket of water is used by the Doctor to erase the chalked formula from the wall, under the Pilot’s orders. However, the act of erasure is a ruse—the Doctor has already altered the formula into a lethal variant. The bucket serves as a tool for compliance, masking the Doctor’s true act of sabotage. Its use underscores the tension between obedience and defiance in the scene.
