Arbitan’s Assassination and the Crew’s Forced Departure

After the TARDIS crew reluctantly agrees to Arbitan’s blackmail—retrieving the five keys of Marinus to prevent the Voord from seizing control—Barbara impulsively activates a teleportation device, vanishing instantly. Arbitan, sensing urgency, orders the Doctor, Ian, and Susan to follow her through the devices, warning them that if the Voord breach the building, they must destroy the keys rather than let them fall into enemy hands. As the crew vanishes, a Voord operative silently approaches Arbitan from behind and stabs him in the back. His dying words—‘For the sake of all my people, I hope you succeed’—underscore the irreversible stakes: the Voord’s campaign has escalated to murder, and the TARDIS crew are now the sole hope of fulfilling Arbitan’s mission. The scene pivots from crisis to desperate action, forcing the companions into a high-stakes chase across time and space while leaving Arbitan’s death as a grim reminder of the Voord’s ruthlessness and the planet’s precarious fate.
