Transmat plan sabotaged by power failure

The Doctor's gambit to reverse the transmats as a countermeasure against Noah's control system takeover nearly succeeds as Rogin enters the alcove. However, the plan unravels when Sarah removes the electrodes from the Doctor's head mid-transfer due to a failing monitor, plunging the room into darkness as the power fails entirely. This leaves Rogin and Harry trapped in transit while Sarah and the Doctor are stranded in the darkened tranquiller room, now under direct assault from a Wirrn larva that exploits the station's vulnerability. The failure exposes a critical flaw in their strategy just as the crew's last defensive option—electricity-based Wirrn neutralization—requires coordination with the control center that is now compromised. key_dialogue: [ DOCTOR: Why? Why have they gone over to the attack? VIRA: They want to destroy us. DOCTOR: But they've only to wait. In their adult form they'll be a thousand times deadlier. Fission guns will have no effect then. HARRY: A hundred? We won't stand a chance. How can we fight a hundred of those? DOCTOR: Electricity. Only by electricity. That's the one thing I found out. ]

Intensely tense and conflicted, torn between her duty to revive protocol and the raw exigency of the moment.

Vira responds to Sarah’s removal of the electrodes with alarm but quickly shifts into defensive action, raising her weapon to fire at the larva. She engages verbally with the Doctor, questioning his assessment of the Wirrn danger and expressing immediate concern about their trapped state, reflecting her conflicted loyalty between survival and protocol.

Goals in this moment

Ark's Transmat System

The Ark’s transmat system is activated by the Doctor to reverse the flow and allow the crew to escape via the Alcove. However, Sarah’s removal of the electrodes mid-transfer interrupts the process prematurely, aborting Rogin’s transit and stranding the remaining crew in darkness. The failed reversal exposes the system’s fragility and eliminates their primary escape route.

Before: Functional and actively being used for reverse-transmat transfer …
After: Aborted mid-transfer; system now offline in the Tranquiller …
Before: Functional and actively being used for reverse-transmat transfer with Rogin on the platform.
After: Aborted mid-transfer; system now offline in the Tranquiller Room due to power disruption.
Revive Station Console

The Revive Station Console is central to the transmat reversal operation, providing the interface controls used by the Doctor to initiate the risky procedure. Its status refracts the urgency of the moment as wires are exposed and adjustments made frantically, and its failure due to Sarah’s electrode removal becomes a pivot point for abandoning the transmat plan entirely.

After: Operational use aborted; control interface went dark with …
Before: Intact and functional, with the Doctor operating it to reverse the transmats.
After: Operational use aborted; control interface went dark with the power loss.
Station Tranquilliser Device

The Station Tranquilliser Device’s electrodes are affixed to the Doctor’s temples as part of the neural interface experiment during the transmat transfer. Sarah tears these off mid-process, triggering the immediate darkening of the room and halting the transfer. The device symbolizes the fragile bridge between the Doctor’s consciousness and the Wirrn threat.

After: Discarded or torn away, electrodes snapping from the …
Before: Attached to the Doctor’s head, actively transmitting neural data for the transmat experiment.
After: Discarded or torn away, electrodes snapping from the Doctor’s temples as Sarah acts impulsively to stop the harm.
UNIT Fission Guns

UNIT Fission Guns are wielded by Vira and Harry as the only immediate offensive tool available against the larva. Though not ideal, their deployment reflects the crew’s desperate resort to conventional armaments when faced with an overwhelming biological threat. The firing temporarily halts the larva’s advance, demonstrating limited but critical effectiveness.

Before: Retrieved from storage and held ready by Harry …
After: Still deployed and fired at the larva, but …
Before: Retrieved from storage and held ready by Harry and Vira before the larva breached the room.
After: Still deployed and fired at the larva, but their future utility against adult Wirrn is deemed insufficient.

Tranquiller Alcove

The Tranquiller Alcove functions as the control nexus for the transmat reversal attempt. Rogin climbs into this recessed space to initiate the transfer, but the alcove’s isolation amplifies the consequences of Sarah’s intervention—his abrupt vanishing underscores the plan’s failure and catalyzes the shift to electricity-based defense strategies.

Atmosphere Cramped and technical, with the sterile hum of consoles and the distant echo of the …
Function Command post for escape attempt, then center of failed transition
Symbolism Symbolizes false hope in technical solutions and the costs of misjudged gambits
Access Limited to one person at a time due to console ridge access
Rogin’s boots scrape over the console ridge as he climbs into the alcove The console’s erratic blue glow fades abruptly as power fails
Tranquilliter Room

The Tranquiller Room serves as the primary battleground and refuge in this event, its confined space intensifying the danger as a large, light-sensitive larva exploits the emergency darkness. The room’s central console and alcove act as contested functional zones—one for attempted escape, the other for defense—while the Exit Grille becomes a chokepoint for invasion, amplifying the crew’s tactical desperation.

Atmosphere Oppressive panic in semi-darkness, punctuated by sudden illumination from muzzle flashes and emergency systems
Function Isolated crisis chamber under biomechanical siege
Symbolism Represents humanity’s fragile foothold in space and the collapse of their revival sanctuary
Access Vulnerable to alien infiltration via small grilles despite reinforced doors
Emergency lighting casts jagged shadows across flickering monitors The exit grille emits a wet drag sound as the larva presses through
