King is still hanging on the sonar array when another sub drifts by while his air runs out. He hangs his dog tags on the frame, clearly figuring this will be his grave.
Shepard is on the Colorado's PA, giving her own stirring captain's speech about how she's betting on them in their upcoming engagement with the enemy, "because you sailors are a sure thing. Carry on." The subs are moving in, and Shepard gives the order to hit the gas and start rising. Other subs are approaching them and acquiring them as a target.
After the negotiation, Kendal realizes that Chaplin provoked Curry on purpose to get the best deal for his senior officers, knowing Curry was going to split them up. "I had to be sure your emotion would be read as real." Kendal says it was, which Chaplin knows. So he just sacrificed himself for his people. Curry returns with an official-looking executive order, reminding Kendal that the deal is off if he says a word to anyone. Curry tells Chaplin he'll be court-martialed, and agrees to let him address his crew first. Suddenly Straw tears up the order, saying it's expired. To Chaplin and Kendal's confusion, she leads Curry and Admiral Shepard out of the church saying they have the Colorado in sights. "Kill her. Kill her now," Curry orders. Straw starts to give the order, but suddenly the admiral grabs an MPs gun and shoots both her and Curry before getting tackled, and Straw's phone is left squawking in the dirt. On the Colorado, Cameron is reporting that the other boats are closing in, well within firing range, although they haven't yet. "Maybe they don't want to hit a girl," Prosser cracks. "How did you ever stay married?" the girl in question asks. "Stayed deployed," he answers. Shepard realizes someone bought them time, and orders that the torpedoes made good and ready.
On the beach, Curry's being dragged back to a boat, hollering vainly for a radio. By the time he gets one and the Illinois obeys his order to fire, the Colorado has already done so. Her torpedoes explode somewhere between the two subs, and Shepard sends them up through the resulting debris. Looks like they lost the Illinois and the torpedoes it launched at them, but at some point the Colorado is going to have to stop using up all its weapons in the service of not killing anyone. For now, Shepard gets on the phone to the other ships in the area and says there are four nukes spun up and aimed at D.C, and they should "kindly remove your forces from the 200-mile perimeter. Thank you for your cooperation." Prosser looks at her with actual admiration. The bad news? The clock on King's air just ran out.
