The scene where abby walks past dan at the prom and gives him a look is kinda scary. She moves like a ghost/ninja and Luke was able to identify her just by her eyes.
She’s the absolute double of Elizabeth Fritzl, the girl who was locked in a cellar by her father (at least her photos from when she was younger) and it’s always frightened me. I found Abby’s character after the shooting so disturbing.
