Laura presumes it was an animal, but Isaac starts to see this dark creature in the most unexpected places, including an AC vent in his room in the film’s most terrifying sequence. Everyone finds what looks like a witch’s home in the woods, adding to the fable/folk aspects of Barfoot’s story. Thousands of years of storytelling make it clear that nothing good lives in a place like that, but Isaac refuses to give up on his investigation for one major reason: Whatever this thing is, it has Daddy’s head.
