The Justice League bust into the alternate dimension’s Arkham Asylum, where a critically injured Hawkgirl is being kept prisoner. John is NOT HAPPY to see the extent of her injuries. It must be particularly difficult for him because it was his Justice Lord alternate self who did this to her.
The Justice Lords discover the alternate dimension. If you look closely at the footage playing on Batman’s computer you’ll see Hawkgirl feinting at Lex Luthor so that Wonder Woman can brick him with an i-beam. Teamwork, ladies.
How did Hawkgirl and GL get from the back of the group to the front?
