Narrator: It is said that over 150 years ago, in the town of Darkness Falls, Matilda Dixon was adored by all the children. Whenever they would lose a tooth they would bring it to her in exchange for a gold coin, earning her the name, the Toothfairy. But fate was not kind to Matilda. One night fire tore through her home leaving her face horribly scarred. Matilda's burned flesh was so sensitive to light she could only go out at night, always wearing a porcelain mask so no one could ever look upon her face. One day two children didn't come home. The town's people blamed Matilda - they hanged her, tearing of her mask, exposing her hideous face to the light. And with her dying breath Matilda laid a curse upon Darkness Falls. The next morning the little children were found safe and sound. The town buried their secret along with Matilda's body. Since then there are some who believe that Matilda visits the children of Darkness Falls on the night they lose their last tooth, seeking her vengeance on any who lay their eyes upon her face, fulfilling her curse: What I took before in kindness, I will take forever in revenge.

Officer Andy Batten: Lead by example and see what it was.
Caitlin: Black cat. Why not?
Michael: She won't come in the light.
Kyle: Who?
Michael: YOU KNOW WHO.
Officer Andy Batten: Is she gonna get me?
Kyle: Yes.
Caitlin: I can't believe you came.
Kyle: That makes two of us.
Kyle: We stay in the light, we stay alive.
Michael: Toothfairy?
Caitlin: It's just mommy honey. Go back to sleep...
Dr. Travis: Are you crazy?
Kyle: Yeah, a little bit.
Kyle: When this hospital goes dark. We're all dead.
