Donna: I could remember like little bits of naked skin peeking through the holes of the hammock.
Eric: Wow. It's weird but knowing what you went through just makes me feel so much better 'cause you're like totally over it, aren't you?
Donna: And later they came inside and they had like this checkerboard pattern all over their arms and legs! And my dad laughed and said they fell asleep on the hammock. But I knew it was a lie. I knew what he did to my mom!
