Why This Matters Across Episodes
The longer arc this connection carries
Sarah’s initiative in Ep19 to warn Harry (and indirectly the Doctor) about the Cybermen’s attack on Voga creates a causal chain leading to the control room’s crisis in Ep20, where her trapped status becomes the central obstacle to the Doctor’s plan.
