Doctor Dismantles Jo’s Occult Beliefs

In the UNIT garage, the Doctor publicly debunks Jo’s mystical theories about the age of Aquarius by demonstrating Bessie’s erratic behavior through a hidden radio-controlled mechanism. His dismissive tone—calling her ideas 'absurd'—exposes a condescending streak, while Jo’s insistence on unexplained phenomena reveals her openness to the supernatural. The exchange escalates when Yates mentions Devil’s End, triggering the Doctor’s sudden, uncharacteristic alarm, which pivots the scene from playful banter to urgent foreshadowing. The moment underscores their clashing worldviews (rationalism vs. mysticism) and plants the seed for their later conflict over the Daemon threat, where Jo’s intuition may prove critical despite the Doctor’s skepticism. The scene also serves as a narrative bridge, linking the Doctor’s past to the present crisis through his visceral reaction to the location’s name, hinting at unresolved history tied to Devil’s End.

Jo brings up the dawning of the age of Aquarius and its connection to the occult, but the Doctor dismisses it, asserting his belief in scientific explanations for everything, setting up their differing viewpoints.

Dismissive to Argumentative

Bessie unexpectedly starts up and drives erratically around the garage, baffling both the Doctor and Jo; the Doctor then reveals that he was controlling Bessie with a remote device, to prove there is a scientific explanation and to ridicule Jo's idea of magic, although Yates is shocked by the turn of events.

Who Was There

Characters present in this moment

3

Initially defiant and slightly exasperated by the Doctor’s condescension, but her frustration gives way to curiosity when the conversation shifts to Devil’s End. She remains undeterred in her belief that some phenomena lack scientific explanations, and her request to watch the program reflects her proactive approach to investigating the unexplained.

Jo stands near Bessie in the garage, defending her belief in the supernatural and the 'age of Aquarius' with defiance. She watches in frustration as the Doctor reveals the radio control trick, calling it 'infuriating' and rejecting his dismissal of her ideas. Her curiosity is piqued when Yates mentions the TV program about Devil’s End, and she requests a lift to watch it, signaling her eagerness to explore the unexplained further.

Goals in this moment
  • To defend her belief in the supernatural and challenge the Doctor’s dismissive attitude.
  • To seek out additional information about the archaeological dig at Devil’s End, driven by her intuition that there may be more to the story.
Active beliefs
  • Some phenomena cannot be explained by science alone, and the supernatural may play a role in the world.
  • The Doctor’s skepticism is overly rigid, and his 'knavish tricks' undermine genuine inquiry into the unexplained.

Follow Jo Grant's journey

Initially smug and amused by his own trickery, masking a dismissive attitude toward Jo’s beliefs. His emotional state shifts to visceral alarm and tension upon hearing 'Devil’s End,' revealing suppressed anxiety or trauma linked to the location.

The Doctor stands in the UNIT garage, tinkering with Bessie’s engine before revealing a hidden radio control unit from his overalls. He demonstrates Bessie’s erratic behavior to debunk Jo’s mystical theories, adopting a condescending tone ('absurd ideas') while engaging in playful banter with Yates. His demeanor shifts abruptly to alarm when Yates mentions 'Devil’s End,' his voice tightening and posture stiffening as he repeats the name with uncharacteristic urgency, betraying a deep, unresolved connection to the location.

Goals in this moment
  • To debunk Jo’s supernatural theories using scientific reasoning and a practical demonstration (Bessie’s radio control).
  • To assert his authority as a rationalist and mentor, reinforcing his worldview over Jo’s openness to mysticism.
Active beliefs
  • All phenomena have scientific explanations if one knows where to look.
  • Supernatural beliefs are irrational and hinder logical thinking, particularly in a companion like Jo.

Bessie

Bessie, the Doctor’s yellow Edwardian roadster, serves as the central prop in this event, demonstrating the Doctor’s hidden radio-controlled mechanism. Under his command, Bessie lurches forward, spins independently around the yard, and reverses back into the garage, debunking Jo’s supernatural theories with a practical, scientific explanation. The car’s erratic behavior—controlled by solenoids and a solar mechanism—highlight the Doctor’s technical ingenuity and his dismissive attitude toward mysticism. Bessie’s role extends beyond a mere demonstration; it symbolizes the clash between rationalism and the unexplained, setting the stage for the Daemon threat’s later revelation.

Before: Parked in the UNIT garage with its engine exposed, revealing the Doctor’s modifications, including the hidden radio control unit. The car is stationary but primed for the Doctor’s demonstration.
After: Returns to its parking place in the garage after the Doctor’s commands, its engine quiet but its role in the debate now cemented. The radio control unit remains concealed in the Doctor’s overalls, ready for future use.
Bessie’s Remote Control

The Doctor’s radio control unit is a hand-sized device retrieved from his overalls pocket, used to remotely operate Bessie. He twists its dials to make the car lurch, spin, and reverse, revealing the 'magic' behind Bessie’s behavior as a scientific trick. The device underscores the Doctor’s preference for empirical evidence over supernatural explanations, serving as a tool to assert his authority and debunk Jo’s theories. Its concealment in his overalls adds a layer of deception, highlighting his playful yet condescending approach to teaching.

Before: Concealed in the Doctor’s overalls pocket, undetected by Jo or Yates until the moment of revelation. The unit is fully functional and ready for use.
After: Returned to the Doctor’s overalls pocket after the demonstration, its purpose fulfilled for this moment but available for future use. The unit remains a symbol of the Doctor’s scientific pragmatism.
Doctor's Overalls

The Doctor’s overalls serve as a practical garment for tinkering with Bessie, but their deep pockets also conceal the radio control unit, enabling his 'knavish trick.' The overalls symbolize his hands-on, mechanical approach to problem-solving and his ability to blend deception with scientific demonstration. Their role in this event is subtle but crucial, as they facilitate the concealment and reveal of the radio control unit, adding a layer of theatricality to the Doctor’s debunking.

Key Dialogue

"JO: But it really is the dawning of the age of Aquarius. DOCTOR: So? JO: Well, that means the occult. Well, you know, the supernatural and all that magic bit. DOCTOR: You know, really, Jo, I'm obviously wasting my time trying to turn you into a scientist."
"JO: Yes, but suppose something was to happen and nobody knew the explanation. Well, nobody in the world, in the universe. Well, that would be magic, wouldn't it? DOCTOR: (Bessie starts up and drives off.) You know, Jo, for a reasonably intelligent young lady, you do have the most absurd ideas."
"DOCTOR: Would you believe magic? YATES: Magic? DOCTOR: Hmm. YATES: No! DOCTOR: Well, Jo would. JO: That's not fair. DOCTOR: Well, you explain it then. JO: I don't know. I suppose you did it. DOCTOR: (Holding up a radio control unit.) Naturally. Or should I say scientifically. Solenoids and a solar mechanism in Bessie and a radio control unit here. You see how easy it is to be a magician?"
"YATES: Devil's End. The village near the dig. DOCTOR: Devil's End? Devil's End? YATES: Doctor, are you all right?"
