Why This Matters Across Episodes
The longer arc this connection carries
The Doctor’s sewer diagram and analysis in Episode 15 directly motivate UNIT’s sewer incursion in Episode 16. This causal link ties Isobel’s photographic mission to the broader UNIT offensive, creating a parallel trajectory where her actions and the military’s converge in the same hostile space.
