Why This Matters Across Episodes
The longer arc this connection carries
The ultimatum forces the Doctor into a high-stakes negotiation, which Chen later exploits to secure leverage over the Daleks. This leverage backfires when the Daleks capture Chen themselves, demonstrating Chen's ultimate betrayal by the Daleks.
