Chen’s Dalek Gambit Revealed

Mavic Chen’s office becomes the nerve center of his genocidal ambition as he openly admits his alliance with the Daleks to Karlton, revealing his plan to replace Trantis as the Daleks’ second-in-command. The theft of the taranium—critical to his power—has forced him into a desperate gambit: he orders Karlton to activate Emergency Plan B, a preemptive strike against the Doctor’s group after their crash-landing at the experimental station. Chen’s ruthless pragmatism is on full display as he dismisses Trantis as a liability and praises Sara Kingdom’s efficiency, signaling the full deployment of his Special Forces to hunt down Bret Vyon and recover the taranium. The scene marks the point of no return: Chen’s betrayal is now public within his inner circle, and the Daleks’ conquest of the Solar System is accelerating. The Doctor’s companions are now fugitives in a system where Chen’s authority is absolute, and the Daleks’ patience is nonexistent.
