The narrative assertion
"The Doctor's insistence that the detected contact is heading toward the castle and is the submarine (beat_4450849189908beb) compels Hart to hear the Doctor's plan to identify the castle as the key to the situation (beat_246bca3c5971f39b), advancing the narrative toward the confrontation at the castle."
