Gearing Up For Stranger Things Season 2? Don't Forget How Season 1 Ends

Mike's older sister, Nancy (Natalia Dyer), and Will's older brother, Jonathan (Charlie Heaton), slowly become friends as they spend time together searching for a missing Barb. This infuriates Nancy's boyfriend, Steve (Joe Keery), as he suspects that they have feelings for each other. However, in the season finale, the trio put their differences aside and set a trap for the Demogorgon, successfully injuring the creature. A month after Will's return and the discovery of Barb's demise, Nancy has resumed her relationship with Steve, both of them becoming good friends with Jonathan.
