One night, Batwoman stops a group of Tenebrae from harming a teenage party. She is unexpectedly assisted by a German Jew, named Helena, who claims to be the leader of the German Youth Resistance.

Later on, Brother Night takes Batwoman and tries to make use of her. But Batwoman attacks his Tenebrae, with the help of the German refugees. Selina and Helena arrive to assist her as well.
