The boys bring Eleven to Mike's house, where they disagree on how to deal with her. Mike agrees to let her sleep in his basement that night. Will's brother Jonathan visits his estranged father Lonnie in Indianapolis to search for Will, but Lonnie rebuffs him. Eleven reveals to Mike that "bad people" are looking for her and, after recognizing Will in a photo and demonstrating her telekinesis, convinces the boys to trust her, as they believe that she could help them find Will. Using the Dungeons & Dragons board, Eleven indicates that Will is on the 'Upside Down' side of the board and is being hunted by the 'Demogorgon' (the creature). Hopper's search party discovers a scrap of Eleven's hospital gown near the lab. Mike's sister Nancy and her friend Barbara 'Barb' Holland go to a party with Nancy's boyfriend Steve Harrington. Searching for Will near Steve's house, Jonathan secretly takes photographs of the party. Nancy gets drunk and has sex with Steve. Joyce receives another call from Will, hears music playing from his stereo, and sees the creature coming through the wall. Barb, left alone by the swimming pool, is attacked by the Demogorgon and vanishes.
