Seaweed Links Toxic Gas to Maggie’s Attack

The Doctor confirms Maggie’s coma was induced by the same toxic gas found in the oxygen room, directly linking the refinery’s malfunctions to her attack. Harris reveals Maggie was stung by seaweed before the gas incident, while Victoria discovers wet seaweed in Harris’s study—an unnatural, deliberate intrusion. The Doctor warns against touching it, suspecting it was planted to harm Harris, exposing a coordinated, malevolent force targeting the Harrises. Jamie’s mention of seaweed near the pipeline reinforces its connection to the refinery’s disturbances, while Victoria’s observation that the seaweed ‘didn’t move’ hints at its unnatural, possibly sentient nature. The scene shifts from medical crisis to a broader conspiracy, implicating the seaweed as both a weapon and a clue to the refinery’s supernatural threat.
