Why This Matters Across Episodes
The longer arc this connection carries
The abduction of Polly (Polly’s disappearance) in Episode 31 leads to the alien doppelgänger taking her place, which the Doctor and Jamie first encounter during immigration interrogation in Episode 32. This establishes the central mystery driving the plot across episodes.
