Why These Connect

Why This Matters Across Episodes
The longer arc this connection carries
Harry’s disappearance — orchestrated by Zygon demand for a ‘body print’ — sets off a chain of pursuit that ultimately uncovers the heart of the Zygon operation. This establishes Sarah as Harry’s protector and the duo as key informants to the Brigade.
