Casey has dead eyes, like I remember reading about in JAWS years ago, the eyes of a shark. No feeling, no soul behind it, no one with a heart at home. The only difference is that the shark kills to eat and Casey killed to get her precious daughter out of the way. If she doesn’t get the death penalty, I pray that this animal never, ever gives birth to a child again.
Eyes - of - a - shark.
Very, very apt description.
As bad as her eyes are, her mouth is even worse! It holds all the tension and hate within her. As someone wrote, that mouth makes her look like an angry guppy.
