Sooo can we just assume it's Adria Arjona after all? If indeed it's her, I'd say she has had bad timing with getting that role.
Anyway, after years reading about how bad the DCEU did for not having solo movies before Justice League, how were people on board this project? They were just doing a JL/Guardians of the Galaxy hybrid all along! Not counting they weren't giving each hero their time to properly shine, or the big confusing canon they were trying to shoehorned...
As bad as allegedly bad the DCEU was, it was still better than this mess that we were presented with as THE big fix of DC movies
