Why This Matters Across Episodes
The longer arc this connection carries
The Cybermen's surveillance of the team via the android's ultrasonic transmitter (E20) is enabled by the earlier intrusion detection by military scouts (E19). This links the two episodes' peril: the quarry alarms become the Cybermen's alert system.
