Why These Connect
The narrative assertion
"The Doctor’s revelation that he left the activated TCE in the Master’s TARDIS directly causes the Master’s downfall in the final act. This ingenious trap transforms the TCE—once a tool of elimination—into a means of containment, closing the causal loop opened in Act 1."
