Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Turlough’s observation of the TARDIS power drain (Episode 17) foreshadows his later desperation to seek external power to resolve his situation, leading him to summon the Black Guardian (Episode 18). The energy drain symbolizes his own draining agency and autonomy."

Why This Matters Across Episodes
The longer arc this connection carries
The unexplained power drain in the TARDIS introduces the theme of theft and manipulation, which parallels Turlough’s own 'tapped' agency. His subsequent attempt to summon the Black Guardian is directly motivated by his perceived inability to navigate the crisis alone, showing how the earlier event escalates his psychological dependency.
