S9E20 · The Mutants Part 6

Ky's mutation begins in crisis

The Doctor seizes a chance to accelerate Ky’s mutation using the crystal, overriding his own warnings about a high-radiation chamber. Sondergaard rushes the crystal to the stricken Ky while the Marshal returns, seizes control again, and condemns the Doctor’s allies to die in toxic air. As guards hustle Jo and Sondergaard toward the chamber, Ky convulses on the floor, his body already responding to the unleashed energy. The scene collapses into chaos as Ky’s physical transformation visibly accelerates, setting the stage for his catastrophic emergence as a telepathic force. key_dialogue: [ INVESTIGATOR: Other ships will come from Earth. MARSHAL: Oh, they'll be room for them. You should be grateful to help me. We'll begin a new Earth, the centre of a new empire. DOCTOR: It's all right, Investigator. He's quite mad. ]

Driven by a mix of determination and anxiety, the Doctor’s urgency masks deep concern for Ky’s survival and Jo’s safety.

The Doctor rapidly attaches the bio-catalytic crystal to the particle reverser, accelerating the mutation process despite the obvious dangers posed by the thaesium radiation chamber. His hands move with urgent precision, showing disregard for his own warnings.

Goals in this moment
  • Save Ky Solon by accelerating his mutation through the crystal’s catalytic properties

Anxious and focused, Sondergaard moves with clinical speed to leverage the crystal’s power before it’s too late, knowing the chamber’s radiation is escalating toward fatal levels.

Sondergaard retrieves the crystal and rushes to Ky’s side, placing the glowing artifact in Ky’s hands as the Solonian’s body convulses from accumulated radiation exposure and the crystal’s catalytic energy.

Goals in this moment
  • Stabilize Ky’s condition through the crystal’s bio-catalytic effect
  • Counter the Marshal’s atmospheric terraforming agenda by weaponizing Solos’ natural mutation cycle
Active beliefs
  • The Marshal’s regime is terminally corrupt and must be dismantled

Supporting 2

Urgency and dread fill Jo as she comprehends the radiation chamber’s lethal threat and Ky’s accelerating physical transformation.

Jo takes the key from the Doctor and moves to lock the door, but her primary focus shifts to assisting Sondergaard and watching over Ky with urgent concern as he convulses and begins to mutate.
