Filer replica exposed and destroyed

The Doctor is ambushed in the Light Acceleration Laboratory by a Filer replica, which attempts to force him to Axos. The Doctor resists using Venusian karate, recognizing the replica as an imposter. The real Filer arrives, shooting at the replica before a brutal hand-to-hand fight ensues. The replica is ultimately destroyed when it rushes into the light accelerator, exploding into a foaming mass. The Doctor’s suspicion of Filer’s true identity deepens, as he questions whether the surviving Filer is genuine or another replica. The confrontation escalates the Doctor’s distrust of Axonite’s influence and the broader conspiracy, while also highlighting the violent stakes of the Axons’ deception.
