"Love and Other Acts of Courage"
Hal Mason and Maggie they stumble upon a mass grave of naked de-harnesed children while on a routine patrol. They find a sole survivor among the corpses - Karen Nadler. Hal rushes Karen back to the 2nd Mass at their hospital camp so that Dr. Glass can treat her.
During Karen's recovery she shows increased strength, hearing and inhuman agility and speed. She carefully manipulates Hal and Ben Mason, playing on their emotions. She targets Hal's affection for her and uses Ben's skepticism against him.
Maggie confronts Karen about her intentions, asserting that Karen is manipulating the boys and ordering her to leave immediately. Karen attacks Maggie's emotions, claiming that she doesn't deserve Hal and that she's nothing compared to her. She targets Maggie's past, saying that she enjoyed being used by Pope's gang for sex rather than hating it like she claims. Maggie says that Karen doesn't know her and attempts to shoot Karen. Karen effortlessly disarms Maggie and seriously wounds her by throwing her against a wall. The impact tears open the stitches from the gunshot wound. Maggie is left for dead and bleeding out on the floor. Karen makes a break for it with Ben.
They escape to the rooftop and are confronted by Hal. Karen pits the brothers against one another by claiming that Maggie tried to kill her. She says that she is scared of prejudice from the 2nd Mass because she has been de-harnessed. Hal insists that both of them come back to the 2nd Mass, holding them at gunpoint. Ben reacts by apologizing and getting close to Hal. He puts Hal in a choke hold and knocks him out. Ben and Karen jump down from the roof without injury and run into the woods.
Tom is warned about Karen by Pope. Pope has rejoined the group after being discovered by the Berserkers, having barely survived a skitter attack. Pope describes an encounter with a de-harnessed girl and warns Tom that she is capable of reaching into your mind and forcing you to give her answers.
Tom realizes that Pope is describing Karen and rushes to the recovery room, finding the injured Maggie. He storms to the roof and discovers Hal unconscious. Tom gazes into the woods after Ben.
