Howard gives Michelle a tour of his bunker, introducing her to Emmett, his construction assistant. Through a viewport at the airlock, Howard shows her two decayed pigs outside, supposedly killed in the attack. Michelle also sees Howard’s truck and recalls it striking her car. She privately talks to Emmett, who assures her the attack is real: he begged to be let in after witnessing the attack. During dinner, Howard shows flashes of jealousy when Michelle grows closer to Emmett. Michelle steals Howard’s keychain and flees. At the airlock, she prepares to open the outside door when she witnesses a woman covered with lesions screaming to be let in before dying. Michelle retreats to the bunker, and Howard explains that he accidentally struck her car while rushing to the bunker. Michelle is seemingly convinced.

Over the next few days, the trio begins to adapt to life underground, and Howard opens up about his daughter, showing Michelle a photo. After something loud passes overhead, the air ventilation system fails. Howard sends Michelle through a small duct to reactivate it. In the control room, she finds a padlocked skylight with the word “HELP” scratched on the inside, and an earring she saw in the photo. Michelle shares this with Emmett, who recognizes the girl as a local who disappeared two years earlier; Howard’s actual daughter left with his wife.
