Earth-X

Leota Adebayo decides to go for a walk in the idyllic and seemingly "perfect" streets of Earth-2, only for all the passersby to begin staring at her. Elsewhere, Emilia Harcourt points out that she hasn't seen a single person of color since she arrived on Earth-2. As Keith Smith leads all the white people in the neighborhood to chase down Adebayo while calling her "a black", Peacemaker examines an American flag on someone's desk and— to his horror— finds a swastika instead of fifty stars, confirming that "Earth-2" is actually Earth-X, an alternate dimension where the Nazis won World War II.
