In a post-apocalyptic situation, one might see Douglas as the epitome of doing the right thing, regardless of what it may entail. Unfortunately for them, they have already taken Douglas out of the picture when they knocked him out and locked him in a separate room for threatening Gary to leave. He is at the mercy of the entities and forces everyone to open all of their eyes towards the unseen danger. Douglas mercilessly berates her for being a simpleton but is proven correct when they discover that Gary is not a normal human being.

However, things unravel when Olympia, perhaps out of sympathy, allows a stranger, Gary ( Tom Hollander), into the house.

When Greg dies as a result of the idea, he nonchalantly repeats that he told them so. He does not approve of Greg's ( BD Wong) idea of viewing the entities through his house's CCTV system. He downright refuses to let anyone enter the premises, regardless of their condition, as he emphasizes when they let another pregnant woman in Olympia ( Danielle Macdonald) take shelter in the house.

He antagonizes Malorie for being "wasteful" with food, even though she needed to eat more because of her being pregnant. He shows utter disgust at Charlie ( Milton "Lil Rel" Howery Jr.) for opening up that he's working on a novel. As the film progresses, Douglas begins to get more and more agitated.
