Did we see the Hydra emblem on May? How do we know this is not her entering the behemoth to tear them down all by herself?

I just had an horrific thought. When Fitz was working on the base entrance scanners and they went off declaring an LMD detected. Everyone assumed it was the guy that came in with Mace's suit on a hanger. What if it wasn't a false alarm and it was Fitz. Who does not know he is an LMD?
