Glory Girl looked over her shoulder to see the dogs, looked back to the injured man and the woman, and then flew straight up, disappearing into the gloom of the night sky. She’d left him behind.
It seems odd for Glory Girl to have this reaction to just a civilian checking on the victim. Even under the impression that the civilian would get the victim medical help – which is stupid, since Rachel might just attack the civilian too – Glory Girl would have reason to want Panacea to help him, with her power being far superior to mundane medicine.
The only mitigating factor to this oddness would be that Glory Girl might no longer believe she can help him without the dogs taking her down.
In short, this reaction reinforces the impression that this isn’t just anyone. She might not be a Slaughterhouse Nine member, but she’s almost certainly a parahuman.
And if she were recognizably on Glory Girl’s side, she might’ve tried to make contact and team up against Bitch, not… flee.
