Doctor syncs mind to stop missile launch

The Doctor races onto the bridge as Silurians prepare their final strike against humanity. With seconds left before the missile ignites a global war, he pleads with Ichtar to abandon the launch, warning that both their races face annihilation. The Doctor spots Vorshak restrained by a Sea Devil and realizes the only way to stop the sequence is to synchronize his own mind with the missile guidance system. Vorshak guides him through the perilous abort procedure while Silurians collapse from the hexachromite gas. Ignoring the chaos, the Doctor locks focus as Vorshak directs the electrical charge, ultimately canceling the countdown. The cost is high; Vorshak dies from wounds sustained in the struggle, leaving the Doctor to question if there was another way to end the conflict without sacrificing lives. key_dialogue: [ DOCTOR: Who will replace you? With you dies the last of the Triad, the custodians of your race. What will become of your people then? ICHTAR: You talk in vain, Doctor. Kill them! Kill them! DOCTOR: Did I succeed? ]
