Retconned.
We can leave it as a ‘don’t question it’ scenario for now, but Winger had suggested to me something akin to a sub-eyelid similar to crocodiles and falcons; a thin, transparent membrane which can protect against water and/or tiny specks of dirt when falling at 30 mph to attack prey.
How would it operate? My theory is don’t question it.
Not yet. It’s hard to tell if this is something heard, or if you can feel it, too.
