Why This Matters Across Episodes
The longer arc this connection carries
The intrusion attempt in Part 3 triggers the facility's systems which lead to the contamination spreading, creating the maggot attack in Part 4. This shows the direct chain of events from the Doctor's investigation to the crisis escalation.
