Why This Matters Across Episodes
The longer arc this connection carries
The Doctor's plan to create a replica taranium core in Ep 15 is the direct cause of Chen's downfall in Ep 17. The core's counterfeit nature is revealed during the Time Destructor trial, exposing Chen's deceit to the Black Dalek. This is a direct causal link between the two episodes, with the Doctor's actions driving Chen's fate.
