Chen’s Dalek Alliance Declared

The Doctor, hidden in the shadows of the reception hall, witnesses Mavic Chen—Guardian of the Solar System—publicly align with the Daleks in a chilling display of betrayal. As the Daleks welcome Chen as an ally, he openly declares his eagerness to participate in their plan to conquer Earth and the solar system. The revelation forces the Doctor into immediate action: he flees the city, retracing his steps through the jungle with urgency, abandoning any further observation to prioritize rallying allies and returning to the TARDIS. This moment marks a critical escalation in the Daleks’ threat, as their alliance with Chen—once a symbol of galactic peace—transforms the invasion from a distant menace into an imminent, coordinated strike. The Doctor’s abrupt departure underscores the gravity of the situation, shifting the narrative from investigation to urgent counteraction.
