Rhizome Revealed — The Vine as Predator

Data and Geordi materialize on Surata IV and methodically sweep Riker's last known location, finding no animal life but extensive fossilized remains. Their investigation yields a rhizomatous vine that appears dead until Geordi provokes it — revealing a vicious, thorned appendage and a planet-wide reactive network. The discovery reframes the incident: what looked like an accident is now an active, symbiotic predator that likely fused with Riker's nervous tissue. Geordi's risk-taking and Data's clinical caution create a telling character contrast while the vine's reflexive response raises the biological stakes and propels urgent sample retrieval and medical analysis.

Plot Beats

The narrative micro-steps within this event

3

Data and Geordi beam to Riker’s last known spot, move with deliberate caution, and begin a methodical survey—Geordi sweeping with his VISOR while Data opens a tricorder scan.

ominous caution to focused investigation ["site of Riker's injury"]

Data reports no animal life within fifty kilometers but detects extensive, mostly fossilized remains, prompting Geordi’s "graveyard" read and sharpening the threat profile.

curiosity to foreboding ["site of Riker's injury"]

They isolate an unusual vine—Data tags its structure as rhizomatous and lifts it, yet Geordi’s VISOR spots thermal variations, elevating the vine from harmless-looking to prime suspect.

Who Was There

Characters present in this moment

3

Alert and ready — prepared to execute transport protocols rapidly on command, there is implied professional concern for team safety.

O'Brien is invoked off‑screen by Geordi's communicator call to 'Stand by'; he is implied to prepare transporter systems and await a signal to energize and beam the away team or specimen out immediately.

Goals in this moment
  • Prepare transporter for immediate energizing/beam operation on command
  • Ensure safety and proper protocol are maintained in a potentially hazardous beam‑up
Active beliefs
  • Transporter technology is the fastest means of extraction in an emergency
  • Following procedure and being on standby mitigates risk to personnel
Character traits
procedural reliable alert
Follow Miles O'Brien's journey

Calmly cautious — externally composed and analytical, with an undercurrent of concern about Geordi's safety and the medical implications for Riker.

Data conducts a meticulous tricorder sweep, reports absence of living fauna and presence of fossilized remains, physically lifts and restrains the vine when it strikes and helps expose the thorn for sampling while warning Geordi of the danger.

Goals in this moment
  • Collect an uncontaminated sample for medical analysis
  • Protect Geordi and minimize risk during the physical examination
  • Accurately document the organism's structure and behavior for Sickbay
Active beliefs
  • Scientific observation and controlled manipulation will yield actionable data
  • The organism may be biologically linked to Riker's condition and therefore dangerous
  • Preservation of evidence is paramount to diagnosis
Character traits
clinical precise stoic under pressure methodical
Follow Data's journey

Focused and slightly playful risk‑taking on the surface, masking urgency and a single‑minded determination to secure evidence that could explain Riker's injury.

Geordi sweeps the area with his VISOR, locates the unusual rhizome, deliberately provokes it to create a reaction, adjusts his phaser to sever a thorn, and calls O'Brien on his communicator to stand by for immediate extraction.

Goals in this moment
  • Confirm whether the vine caused Riker's injury by provoking a response
  • Secure a physical specimen (thorn) for medical analysis
  • Enable rapid extraction if the situation escalates
Active beliefs
  • Physical evidence is required to prove causation for Riker's condition
  • Technology (VISOR, phaser, communicator) will keep him and the team safe
  • A controlled provocation will reveal the organism's behavior
Character traits
curious daring practical decisive

Objects Involved

Significant items in this scene

7
Medical Tricorder

Pulaski's Medical Tricorder (here used by Data) performs a meticulous scan of the immediate area, detecting a lack of living fauna and extensive fossilized remains; it provides diagnostic readouts that frame the scene as a graveyard and supports Data's analysis of the vine's rhizomatous structure.

Before: In Data's possession or active at the start …
After: Remains in use, recording the vine's biological response …
Before: In Data's possession or active at the start of the sweep; operating and recording environmental data.
After: Remains in use, recording the vine's biological response for later analysis and transport to Sickbay.
Telepathic Vine

The Surata IV rhizomatous vine initially appears desiccated and harmless; when Geordi provokes it and Data handles it, it reveals an underside thorn and, when the thorn is cut, triggers a planet‑wide reactive oscillation—revealing it as an active, interconnected predator likely capable of fusing with nervous tissue.

Before: Partially buried in the soil, appearing dead and …
After: Physiologically active and oscillating with the surrounding rhizome …
Before: Partially buried in the soil, appearing dead and inert to casual observation.
After: Physiologically active and oscillating with the surrounding rhizome network; physically handled by Data and partially severed (thorn cut free).
Geordi La Forge's VISOR with Visual Acuity Transmitter

Geordi's VISOR is actively used to survey thermal and structural anomalies in the soil and vegetation; it guides Geordi to the rhizome, reveals subtle thermal variations that suggest reactive behavior, and informs the decision to provoke the vine for testing.

Before: Worn by Geordi and actively scanning the area, …
After: Still worn and active after the vine's reaction; …
Before: Worn by Geordi and actively scanning the area, linked to ship sensors.
After: Still worn and active after the vine's reaction; continues to provide sensor feedback to Geordi.
Fossilized Animal Remains (Surata IV)

The fossilized animal remains are surveyed and recorded by Data's tricorder as environmental evidence; they contextualize the planet as a graveyard ecosystem, raising the possibility of long‑term predatory behavior and ecological dominance by the rhizome.

Before: Embedded in the ground around the survey site, …
After: Still present and noted by Data as part …
Before: Embedded in the ground around the survey site, undisturbed and inert.
After: Still present and noted by Data as part of the environmental record; remain as corroborating evidence for the rhizome's historical activity.
Geordi's Pinpoint Phaser

Geordi adjusts and fires a pinpoint phaser to sever the thorn from the vine; the phaser functions as a precise sampling tool rather than a weapon, its cut directly provoking a reflexive, large‑scale reaction from the surrounding rhizome network.

Before: In Geordi's possession, configured for precision work.
After: Has been fired to cut the thorn and …
Before: In Geordi's possession, configured for precision work.
After: Has been fired to cut the thorn and remains in Geordi's control; no damage noted beyond expected use.
Geordi's Portable Communicator (Handset)

Geordi's portable communicator is used to contact O'Brien in the transporter room, creating a direct lifeline between the field team and ship operations and triggering standby protocols for immediate extraction once the specimen is secured.

Before: In Geordi's possession, functioning and ready.
After: Used to call O'Brien and confirm energize; remains …
Before: In Geordi's possession, functioning and ready.
After: Used to call O'Brien and confirm energize; remains with Geordi as the team prepares for possible transport.
Predatory Vine Thorn Specimen

The mean‑looking thorn is the key biological sample: attached to the vine until Geordi severs it with a pinpoint phaser. Its exposure confirms the vine's predatory anatomy and provides the specimen likely responsible for Riker's neural fusion.

Before: Affixed to the underside of the vine and …
After: Severed from the vine by Geordi's phaser and …
Before: Affixed to the underside of the vine and concealed while the vine appeared dead.
After: Severed from the vine by Geordi's phaser and now available as a sample for transport to Sickbay.
