K9 admits tracking failure to Adric

Adric and K9 attempt to track Romana’s path through the Void but K9’s mass detection circuits are catastrophically unreliable, returning readings with an error probability over eighty-seven percent. Adric reacts with disbelief and frustration, forcing K9 to admit his tracking unit has degraded to the point of being actively harmful rather than useful. The revelation shatters their last viable method of locating Romana amid the temporal catastrophe and leaves the Doctor’s survival plan in ruin, forcing an immediate redirection of their efforts. key_dialogue: [ ADRIC: Well, what is the probability of error, K9? K9: Probability of error, eighty seven point seven nine four eight percent. ADRIC: Eighty seven? But that's terrible! K9: The accuracy of this unit has deteriorated below zero utility. ADRIC: You mean you're worse than useless. K9: Affirmative. ]

Who Was There

Characters present in this moment

K9
Robotic Canine Companion
 primary

Functionally neutral, internally opaque

K9 remains motionless but emits a confirming beep before recalculating the probability. His voice processor delivers the brutal figures without inflection, adhering strictly to numerical truth. When Adric insists on nomenclature for failure, K9 repeats the mechanical acknowledgment that his circuits are now actively detrimental, reaffirming his directive compliance even as his function collapses.

Goals in this moment
  • • Provide accurate probability data per primary directive
  • • Admit system failure when utility drops below threshold
Active beliefs
  • • Truth must be stated regardless of emotional impact
  • • Failure thresholds absolve further obligation to function
Character traits
unemotional direct rule-bound precisely factual

Disbelieving frustration masking underlying dread

Adric stands in the featureless Void, gesturing toward a perceived path Romana may have taken. His hopeful expression curdles into disbelief as K9 recites the error margin, pivoting from initial trust in technology to raw frustration over its collapse. He pushes physically toward the machine as if brute insistence could correct its readings, embodying the transition from planning to panic.

Goals in this moment
  • • Determine Romana's location quickly to ensure her survival
  • • Preserve confidence in K9’s reliability as their sole tracker
Active beliefs
  • • If K9 declares a path, following it will lead to Romana
  • • Technology can—and must—be trusted in moments like these
Character traits

Ancient Traken Mass Detection Circuits

K9’s mass detection circuits activate under Adric’s prompting and are immediately strained by the Void’s turbulent chronal energies. Instead of returning meaningful spatial data, the unit generates wildly inaccurate vectors with an eighty-seven percent margin of error. K9 acknowledges that the circuits have degraded below zero utility, rendering the device actively misleading and forcing Adric to accept that their last navigation tool is now harmful.

Places and their significance in this event

1
The Void (Empty Dimension)

The Void serves as an inescapable and disorienting backdrop—a blinding white expanse where temporal currents ripple visibly like disturbed parchment and raw chronal energy raises prickling static on exposed skin. Orientation dissolves instantly, and the lack of solid ground or fixed direction amplifies panic as survival depends on unreliable tools. Here, even technology loses integrity, rendering spatial reasoning nearly impossible.

Atmosphere Disorientingly static and oppressive with an undercurrent of barely contained danger
Function Inescapable navigational nightmare
Symbolism Embodiment of temporal chaos where trust in systems and certainty crumbles
Access No access controls exist; entry implies automatic disorientation and risk of being pulled irrecoverably into …
Blinding white light with visibly rippling temporal currents Persistent static charges prickling exposed skin

Character Continuity medium

"Adric's earlier lesson from K9 about mass detection triangulation (which acknowledges its limitations) dovetails with the later revelation that K9's circuits are 'worse than useless,' reinforcing the theme of failed or unreliable technology."
