Frustrated and defiant—his impatience with the Doctor's measured approach fuels his impulsive sabotage, but beneath the bravado, there's a flicker of doubt about the consequences of his actions.

Steven paces restlessly, his frustration boiling over as he questions the Doctor's plan and the group's inaction. His impatience erupts when he spots the auxiliary control unit, which he smashes with a burst of raw energy, his voice triumphant as he declares the problem solved. He defends his actions to Sara, his tone a mix of defiance and pride, though his body language betrays a hint of uncertainty about the fallout. His sabotage, while effective, exposes the crew's mounting tension and forces a shift from planning to immediate survival.

Goals in this moment
  • Remove the Dalek's control over the ship immediately, regardless of the method.
  • Prove his worth to the group and assert his agency in the face of perceived inaction.
Active beliefs
  • Direct action is often more effective than prolonged planning, especially under urgent threats.
  • His technical skills, though outdated, are still valuable in critical moments.

Follow Steven Taylor's journey

Steadfastly focused but increasingly uneasy—her faith in the Doctor is unwavering, but the ship's erratic behavior and Steven's recklessness create a undercurrent of tension she works to suppress.

Sara stands beside the Doctor, her posture alert and her expression a mix of trust and concern. She interrupts Steven's skepticism with a firm vote of confidence in the Doctor's plan, her voice steady and authoritative. When Steven smashes the control unit, she questions the method but not the motive, her pragmatism tempered by a growing urgency as the ship's course veers toward Kembel. She assists the Doctor in preparing the replica, her actions efficient and her demeanor a stabilizing force amid the chaos.

Goals in this moment
  • Ensure the taranium core replica is completed swiftly and accurately to outmaneuver the Daleks.
  • Mediate between Steven's impulsiveness and the Doctor's strategic approach to maintain team unity.
Active beliefs
  • The Doctor's intellect is their best weapon against the Daleks, and his plans should be followed without hesitation.
  • Steven's actions, though drastic, are driven by a desire to protect the group and should be understood rather than condemned.

Coldly determined—its actions are driven by strategic necessity, not emotion, but the crew's defiance fuels its resolve to reclaim control and eliminate them.

The Black Dalek is not physically present but looms as an unseen force, its influence manifesting through the ship's sudden course change toward Kembel. Its control over the auxiliary unit is implied, a silent but relentless pursuit that disrupts the crew's plans. The Doctor's deduction of Dalek influence and Steven's sabotage of the control unit temporarily sever this connection, but the threat of the Black Dalek's return—and the crew's eventual confrontation with it—hangs heavily over the scene.

Goals in this moment
  • Regain control over the stolen pursuit ship and its occupants through technological manipulation.
  • Ensure the taranium core is recovered or destroyed, eliminating any threat to Dalek operations.
Active beliefs
  • The crew's deception will fail, as the Daleks' superior technology and logic will ultimately prevail.
  • Any resistance to Dalek authority must be crushed swiftly and without mercy.

Dalek Pursuit Ship Navigation Override Panel

The auxiliary control unit is a critical Dalek-installed device linked to the ship's main systems, allowing remote manipulation of the vessel's course. Steven identifies it as the source of the ship's erratic behavior and, in a burst of frustration, smashes it with his bare hands, severing the Daleks' influence. The unit's destruction is both a tactical victory—buying the crew precious moments of autonomy—and a symbolic act of defiance against Dalek control. Its sparking wreckage underscores the urgency of the moment and the crew's desperate struggle for survival.

Taranium Core Fabrication Notes (Doctor's)

The Doctor's taranium core replication notes are a hastily scribbled but meticulously detailed record of the core's properties, measurements, and the steps required to create a convincing replica. These notes serve as the blueprint for the crew's deception, their existence a testament to the Doctor's scientific acumen and improvisational genius. As the ship lurches toward Kembel, the notes become a race against time—every second spent poring over them is a second closer to Dalek recapture, making their completion a matter of life and death.

Dalek Pursuit Vessel (Kembel Escape Sequence)

The Dalek pursuit ship's cramped, flickering interior serves as a claustrophobic battleground where the crew's survival hinges on their wits and the ship's fragile systems. The hum of machinery and the glow of consoles create a tense, urgent atmosphere, while the sudden lurches of the vessel underscore the crew's vulnerability. The space is both a refuge and a prison—its confined quarters force the crew into close quarters, amplifying their tensions, while its advanced (but compromised) technology offers both hope and peril. The ship's erratic course toward Kembel transforms it from a temporary sanctuary into a deathtrap, its walls closing in as the Daleks' influence reasserts itself.

"STEVEN: Will it work, Doctor?"
"DOCTOR: No, course it won’t, my dear boy. That’s the whole point."
"DOCTOR: Yes, thank you, thank you my dear, thank you. I’ll have a good try. And I think that will give us sufficient breathing space. What’s that?"
"SARA: We’re changing course. We’re moving away on a selected route."
"DOCTOR: Good gracious, we’re on the course for the planet Kembel. You know, I’m very much afraid that we’re under the Dalek influence."
"STEVEN: Ah, that settles that."
"SARA: Isn’t that a rather drastic way of dealing with things?"
"STEVEN: Sara, the technology of my age may be hundreds of years behind yours and the Doctor’s, but there are still some things I can handle."
