Bulic confirms Silurian breach in airlock

The sudden failure of the airlock’s magnetic locks and the activation of its automatic pumps expose the presence of intruders. Bulic deduces the Silurians have infiltrated the Sea Base’s defenses, while Tegan questions how the breakdown reveals their foes’ location. The moment ratchets up the threat as the base’s vulnerabilities become brutally clear, culminating in Bulic’s stark confirmation that the enemy now occupies the otherwise secure airlock. key_dialogue: [ BULIC: Any change? GUARD: No, sir. BULIC: The magnetic locks on the outer door are blown. They're in the airlock. ]

Airlock Three Emergency Override Panel (Sea Base Four)

The crimson indicator lights atop Airlock One’s control panel switch off abruptly, signaling the loss of the primary containment system. Their darkening provides the first visual confirmation of lock failure, while Bulic’s deduction follows from observing this system-level breakdown.
