Why This Matters Across Episodes
The longer arc this connection carries
Tyram's initial interrogation establishes a thread of distrust between the Vogans and outsiders. This distrust manifests in Harry's delayed revelation, which exacerbates the crisis by informing the Doctor (and thus the audience) of Sarah's dire plight on the Beacon.
