Doctor and Sarah uncover Kraal invasion plot

The Android Infiltrators are revealed as the Trojan figures to be deployed via space shells before Marshall Chedaki's main fleet arrival, their construction facilitated by Crayford’s memory prints.

The Leader Rocket Loading Bay is referenced via Styggron’s off-screen command as the destination where Crayford must rush to oversee the android deployment sequence.

Space Shells are described as meteorite-shaped concealment devices that will release android infiltrators undetected into Earth’s atmosphere minutes after Crayford’s staged return.

The Strategic Defence Complex emerges as the android infiltrators’ primary target, whose capture by reconstructed operatives will disable Earth’s defenses for the Kraal virus deployment.

The Ultimatum is invoked by Crayford as a coercive document outlining Earth’s false choice between submission to the Kraals or annihilation, leveraged to justify his reconstructed body’s return.

Memory Prints from Crayford’s reconstruction are described by the Doctor as the templates Kraals use to program their android infiltrators, turning his reconstructed mind into a weapon.

The Kraal Brig functions as the confined, sterile chamber where Crayford’s revelations unfold under the pressure of artificial lighting and the ship’s ominous hum, amplifying the prisoners’ helplessness.

The Kraals orchestrate the entire invasion scheme through their simulated village anchor in Earth’s cultural psyche, relying on Crayford’s reconstructed body to sell the staged return while android infiltrators prepare key defenses for conquest.

Security Forces disguised as human personnel enforce the Kraal infiltration while Crayford publicly maintains his reconstructed identity, showcasing the eroded chain of command beneath the Kraal ultimatum.
