Why These Connect
The narrative assertion
"Adric’s desperate holographic warning ('He's using me... in a block transfer') plants the first clue about the Master’s programmatic trap. This mysterious clue drives Nyssa and Tegan to interpret the TARDIS’s course as a malign plot, not mere malfunction."
