Lorna digs through some crates for weapons. Strax, apparently having skipped a human anatomy class or two at nursing school, calls her a boy. "She's definitely a girl," the Silurian says appreciatively. "Oh, stop it!" Jenny says. Dorium decides to go over to have a chat with his old friends, the Monks, and promptly gets himself beheaded. His headless body waddles back toward the group along with the Monks. Rory and friends ready their weapons.
"The child is not a weapon!" shouts the Doctor. "She will be," Kovarian promises. Come to think of it, thanks to flesh-Amy's trip to 1969, she already knows how, when and where to start. The Doctor says he won't let Kovarian near the child. "Oh, Doctor, fooling you once was a joy," she says. "But fooling you twice the same way? It's a privilege." The Doctor, realizing what this means, goes running for Amy.
Amy is cradling what she thinks is her baby as the others fight a short distance away. River's voice recites a poem for us: "Demons run when a good man goes to war. Night will fall and drown the sun, when a good man goes to war. Friendship dies and true love lies. Night will fall and the dark will rise, when a good man goes to war. Demons run, but count the cost: The battle's won, but the child is lost." This is interspersed with shots of the fight, with monks wielding their lightning swords and Rory alternately shooting a gun and waving a sword. The Doctor runs and runs through the base. A Monk sneaks up behind Strax. Another blasts Lorna in the chest with a bolt of energy. A panel opens in midair that only Melody can see. "Wakey wakey," Madame Kovarian says. With a soft splat, the baby collapses into white goo down the front of Amy's shirt. She gasps and looks down at the empty blanket. She screams for Rory.
The battle is over when the Doctor finally reaches them. Headless corpses litter the floor. He tells Rory that the baby is a flesh avatar but Rory already knows. Rory goes to console a dying Strax, who discovers that dying in combat isn't what he'd hoped it would be. Rory tries to tell him that he'll be all right, that he's a warrior, but Strax is a nurse. He knows what dying looks like. Jenny is comforting Amy when the Doctor approaches, head bowed and wringing his hands. It was all for nothing, she says. He moves toward her, as if to hug her, but she steps away. "It's not his fault," Jenny says. "I know, I know," Amy says, but she still doesn't let him near her. Vastra calls to the Doctor and says Lorna wants to talk to him.
