Who Was There
Characters present in this moment
Emotionally detached, prioritizing survival logic over sentiment, yet masking deeper hatred for the Cybermen that fuels her ruthlessness.
Rost meets Peri’s urgency with dismissive coldness, refusing aid based on Cryon physiological constraints and bluntly stating rescue is impossible. She reveals the Cybermen’s plan to destroy Earth as a stepping stone to altering history, emphasizing their shared goal of neutralizing Mondas’ demise through Earth’s annihilation.
- • Protect Cryon lives by avoiding direct confrontation with the Cybermen in the warm Cyber Control.
- • Expose the Cybermen’s temporal conspiracy to Peri to secure her understanding—and compliance.
- • The immediate survival of the Cryons must dictate all decisions, even moral ones.
- • The Cybermen’s defeat is an absolute necessity, regardless of collateral damage.
Fiercely pragmatic with a seething animosity toward outsiders and the Cybermen, masking underlying desperation for survival through relentless tactical focus.
Varne matches Rost’s detachment with outright hostility, dismissing Peri’s intelligence and even suggesting her death would be preferable. She reveals Lytton as a secret ally, then explains the Cybermen’s motives in grotesque detail, escalating hostility toward the Doctor as she frames his assistance as a liability.
- • Protect Cryon interests by manipulating allies like Lytton without moral constraint.
- • Undermine Peri’s faith in the Doctor’s invincibility to neutralize potential betrayal.
- • Trust in others is a luxury the Cryons cannot afford; survival justifies any alliance.
- • The Doctor’s chaotic nature makes him a risk rather than a resource in their fight.
Determined but unsettled, her confidence shattered by the Cryons’ chilling pragmatism and the revelation of humanity’s existential threat.
Peri enters the Cryon Cave with urgent pleas, demanding the Cryons act to rescue the Doctor from Cyber Control despite their warnings. She presses for answers about Lytton, only to face outright dismissal and revelations that force her to reassess the entire conflict. Her determination wavers as the true scale of the Cybermen’s plan unfolds.
- • Convince the Cryons to rescue the Doctor despite their refusal.
- • Gather information about Lytton’s involvement and the Cybermen’s true motives.
