Amy doesn’t want to go back upstairs, so she decides to stay with the girls. Time passes and they all start to get worried. They go to the bottom of the stairs.
Amy: Nick? Marco?
Lizzie: Fucking answer us!
Suddenly, something rolls down the basement steps, leaving splotches of red behind it. They all scream when they realize it is Nick’s head, and then again when they see the KILLER enter the stairwell above.
