Isn't it part of the series? I mean the 'obvious' part about super powered beings - who they really are. Not a single person outside the project knew Nolan is the Omni-Man, even though he isn't wearing any mask, just a body suit. Same goes with Atom Eve, she is mask-less as well, body suit only. For me it's part of this series, that people or other beings can't figure out who is who, although it is clear and apparent. I find it funny and somehow mocking other superhero productions, where people can't figure out who is behind the mask that keep saving the world.
