Athena came from a clutch Pat had who suffered we believe from incubation stress.
The few hatchlings that survived to birth were deformed. Athena happened to be born without eyes. Other than that she appears healthy. And no, she has no clue she's "disabled", and she sure doesn't let it slow her down. We are toying with the theory she can sense/see shadows, because she reacts if your hand passes in front of her tub between the light and her tub when she is out and about.
