Why This Matters Across Episodes
The longer arc this connection carries
The Doctor's immediate investigation in Episode 31 (based on Polly's testimony) establishes Spencer as a threat. This threat materializes in Episode 34 as the Doctor prioritizes rescuing Polly and Ben, whose abduction is a direct result of their knowledge of the aliens' operation.
