Attempting to return to Berlin, the 666th and their resistance allies are met by Werewolf Squadron at the Havel River. Gretel is shot down, but is found by Axmann, who invites her to join his Berlin faction in the internal Stasi rivalry against the Moscow faction. As bait, he shows her the Stasi files. She refuses and calls in rebel troops to torch the secret facility, but is wounded by gunfire in the chaos. Another group of rebels sneaks Katia into Berlin. Elsewhere in the city, Beatrix reveals Schmidt to be a KGB agent from the Soviet Union, and he reveals his plan to nuke East Germany to make it a bulwark to protect the USSR from the BETA. He orders his guards to execute Beatrix, but they kill him instead.
