More Flashpoint Folderol

The most important thing about Flashpoint, of course, is the question, re: the following panel from Emperor Aquaman numba 3, "What the heck is up with that helmet?"

Is that helmet drawn way out of proportion? Is it floating? Did water-dwelling Mera, Queen of Altantis own a floating helmet in defiance of all logic? 

Why is my life so full of questions?
