Who Was There

Characters present in this moment

4

Confidently convinced, with a protective urgency to help Ian transition from denial to acceptance.

Barbara stands beside Ian, her initial confusion replaced by growing conviction as she witnesses the TARDIS’s impossible interior and the scanner screen’s alien landscape. She actively supports the Doctor and Susan, contrasting sharply with Ian’s skepticism. When the Doctor opens the doors, Barbara is the first to step outside, urging Ian to follow and accept the reality unfolding before them. Her actions—gentle but firm—highlight her role as the emotional bridge between Ian’s resistance and the Doctor’s certainty.

Goals in this moment
  • To reassure Ian and guide him toward accepting the reality of time travel.
  • To demonstrate her own trust in the Doctor and Susan by stepping outside the TARDIS first.
Active beliefs
  • The TARDIS and its occupants are trustworthy, despite the impossibility of their claims.
  • Ian’s skepticism is rooted in fear, not logic, and can be overcome with evidence.
Character traits
Empathetic Quick to trust Supportive Curious Assertive (when convinced)
Follow Barbara Wright's journey

Shocked and disoriented, oscillating between defiance and despair as his rational foundations crumble.

Ian Chesterton clings to his rational worldview, demanding concrete proof even as the TARDIS’s impossible interior and the scanner screen’s alien landscape undermine his skepticism. His stubbornness peaks when he insists the Doctor open the doors, only to be met with the undeniable sight of a prehistoric world. The moment shatters his composure; he stumbles outside, clutching his head, his voice trembling as he repeats, ‘It’s not true. It can’t be.’ His physical and emotional collapse—leaning on Susan, then rejecting her help—reveals the depth of his crisis: a man whose entire understanding of reality has been invalidated in an instant.

Goals in this moment
  • To cling to his skepticism as a shield against the overwhelming evidence of time travel.
  • To find any logical loophole to disprove the Doctor’s claims, even as the proof becomes undeniable.
Active beliefs
  • Time travel is an absurd fantasy, and the Doctor is either a liar or deluded.
  • His role as a teacher and rational thinker requires him to reject the impossible, regardless of evidence.
Character traits
Stubborn Rationally rigid Defensive Vulnerable (when confronted with the unexplainable) Protective of his worldview
Follow Ian Chesterton's journey

Patient and empathetic, with a quiet determination to help Ian adjust to the new reality.

Susan stands as a quiet but steadfast ally to the Doctor, confirming the yearometer’s malfunction and defending his claims against Ian’s skepticism. She exits the TARDIS with Ian, offering him physical support as he stumbles into the prehistoric landscape. Her actions—calm, patient, and protective—reflect her dual role as both the Doctor’s granddaughter and a companion to Ian and Barbara. She doesn’t gloat over Ian’s crisis but instead extends a helping hand, embodying the compassionate bridge between the Doctor’s eccentricity and the companions’ humanity.

Goals in this moment
  • To support the Doctor by validating his claims and assisting with the transition to the prehistoric world.
  • To ease Ian’s shock and help him accept the reality of time travel without judgment.
Active beliefs
  • The Doctor’s knowledge and the TARDIS’s capabilities are absolute, and skepticism like Ian’s is a temporary hurdle.
  • Compassion and patience are essential in helping others adapt to the impossible.
Character traits
Loyal Patient Compassionate Supportive (without condescension) Confident in her grandfather’s assertions
Follow Susan Foreman's journey

Amused and determined, with a hint of exasperation at Ian’s stubbornness, but ultimately focused on the mission ahead.

The Doctor engages in a playful but firm debate with Ian, amused by his skepticism but ultimately impatient with his refusal to accept the evidence before him. He diagnoses the yearometer’s malfunction, checks the radiation levels for safety, and—after Ian’s repeated demands—dramatically opens the TARDIS doors to reveal the prehistoric landscape. His actions are a mix of scientific curiosity, theatrical flair, and paternalistic patience. He exits to collect rock and plant samples, muttering about the ‘disgusting’ alien environment, while his companions grapple with the implications of their new reality. The Doctor’s role here is that of a guide, challenging Ian’s worldview while also protecting his companions.

Goals in this moment
  • To prove the reality of time travel to Ian through undeniable evidence (the prehistoric landscape).
  • To gather scientific samples to determine their exact temporal location and ensure the safety of his companions.
Active beliefs
  • Skepticism is a natural but temporary response to the impossible, and evidence will eventually prevail.
  • His role as a time traveler includes both educating his companions and protecting them from the unknown.

TARDIS (Time and Relative Dimension in Space)

The scanner screen is the first piece of evidence that challenges Ian’s skepticism, displaying the alien prehistoric landscape outside the TARDIS. Susan and the Doctor direct Ian’s attention to it, but he initially dismisses it as a trick. The screen’s role is to plant the seed of doubt in Ian’s mind, preparing him for the moment when the Doctor opens the doors and forces him to confront the reality firsthand. Its grainy, otherworldly image foreshadows the shock to come.

Doctor's Prehistoric Landscape Samples (Rocks and Plants)

The unfamiliar prehistoric plants are glimpsed through the TARDIS doors as the Doctor opens them, serving as another piece of visual evidence that undermines Ian’s skepticism. Their alien appearance—thick, twisted, and unlike anything from 1963—reinforces the group’s dislocation in time. The plants symbolize the hostility and strangeness of the new world, contrasting with the safety of the TARDIS interior. Their presence foreshadows the challenges the companions will face as they adapt to their prehistoric surroundings.

TARDIS Yearometer

The yearometer is a critical diagnostic tool that fails to provide a reliable reading, heightening the uncertainty of their temporal location. The Doctor briefly mentions its malfunction, using it as partial evidence to support his claim that they have traveled back in time. While it doesn’t directly resolve Ian’s skepticism, it underscores the TARDIS’s limitations and the need for external proof—ultimately leading to the Doctor’s decision to open the doors.

Prehistoric Landscape (Episode 2, An Unearthly Child)

The prehistoric landscape is revealed as the Doctor opens the TARDIS doors, serving as the undeniable proof that shatters Ian’s skepticism. Its jagged rocks, yellow sand, and unfamiliar sky create a hostile and alien environment that forces the companions to confront the reality of time travel. The location’s role is to act as a catalyst for Ian’s crisis of belief, as well as a testing ground for the group’s ability to adapt to the impossible. The atmosphere is one of awe and dread, with the unfamiliar cries of alien birds and the vast, empty expanse reinforcing the group’s isolation in time.

TARDIS Central Console Room

The TARDIS interior serves as the group’s temporary sanctuary, a place of relative safety and familiarity before they are forced to confront the alien world outside. Its humming energy and steady floor provide a false sense of security, contrasting with the harsh prehistoric landscape revealed when the Doctor opens the doors. The TARDIS’s role in this event is to act as a liminal space—a threshold between the known and the unknown—where Ian’s skepticism is tested and ultimately broken. The location’s atmosphere is tense, with the Doctor’s amusement, Ian’s defiance, and Barbara’s growing conviction all colliding in this confined space.
