Oil Rig Electronic Disruption Signal

A pulsing electromagnetic phenomenon that manifests as two distinct but psychologically interconnected disturbances in Sickbay and the Radio Room. Oil Rig Interference Signal (hallucinatory distortion): - Irregular, ominous rhythm flooding Sickbay with artificial feedback - Tactile hallucinations: shrieking metal, churning North Sea, Munro's drowning fight - Targets Harry's mind specifically (visual/auditory/tactile hallucinations) Zygon Sonic Jamming Interference (active suppression): - Electronic white noise barrage pulsing from speakers - Active suppression field strangling oral transmissions - Cuts off Munro's distress call to Hibernian Control mid-transmission - Seals fate before physical demolition begins Unified Entity: The pair is recognized as the same underlying phenomenon (electromagnetic interference during Zygon attack), though expressed through different narrative lenses (hallucinatory signal vs active communication scrambler). Both were present in overlapping scenes during the same attack sequence, suggesting they were manifestations of the Zygons' sabotage technology in different locations and functional roles. The surviving entity will consolidate these descriptions with clear functional partitioning.

3 moments
S13E1 · Terror of the Zygons Part 1
Munro’s desperate final transmission as rig collapses

The radio’s signal is amputated mid-transmission by a rising tide of electronically synthesized white noise that drains speech of sense and steers Munro’s Mayday calls into oblivion. This active jamming immediately precedes the instantaneous collapse of the channel, leaving only scrambling static where human voices once struggled.

Before: Operational but marginally so, its circuits already whispering under load
After: Silenced permanently by explosion and submersion

S13E1 · Terror of the Zygons Part 1
Harry recounts rig explosion horrors

The Oil Rig Interference Signal manifests brutally in the sickbay’s sterile environment, flooding Harry’s mind with tactile hallucinations. Though physically invisible, its ominous rhythm and electromagnetic assault force him to confront the vivid destruction of the Charlie Rig as if reliving it firsthand, acting as both a weapon and a medium for the transmission of violence.

Before: Dormant or latent, its presence triggered by external forces connected to the rig’s sabotage.
After: Active and destructive, having successfully elicited Harry’s traumatic recollections and disrupted the sickbay’s clinical tranquility.

S13E1 · Terror of the Zygons Part 1
Harry relives rig explosion in sickbay

The interference signal manifests as a palpable psychic force, its ominous pulsing rhythm overloading Harry’s perception and triggering a violent psychic flashback. Its tactile presence presses in on him like a living entity, flooding the sterile Sickbay environment with artificial feedback that destabilizes his mind and swamps his defenses.

Before: Active and unseen, its effects dormant until Harry’s mental state becomes vulnerable
After: Unchanged but now associated with Harry’s breakdown, drawing attention as the catalyst for the crisis
