The Stranger Things season 1 finale ended with the apparent death of Eleven, and season 2 revealed she was alive and living with Hopper – but how did he know she survived? Throughout its four-season run, Stranger Things has left a number of mysteries that are still waiting to be solved, but there are some others that have been forgotten by audience as there have been more interesting and exciting things happening in Hawkins, especially following the Stranger Things season 4 ending. Among these forgotten mysteries is how the Hopper and Eleven reunion happened after Eleven survived the Demogorgon’s attack in season 1.
At the end of season 1, the Demogorgon went after Eleven and the rest of the group at Hawkins Middle School. Mirroring the Stranger Things season 4, volume 2 finale, the original crew built their own sensory-deprivation tank. Dr. Martin Brenner and company arrived to take Eleven back to Hawkins Lab, and the agents were killed by the Demogorgon and Brenner was attacked, but he’s said to have survived. The monster then went after Eleven, Mike, Dustin, and Lucas, and so Eleven stepped up and “sacrificed” herself in order to defeat the Demogorgon, which disintegrated. However, in hindsight, the Demogorgon likely survived and was only transported to the Upside Down, as its «disintegration» looked highly similar to how Eleven disposed of One — also known as Stranger Things season 4 villain Vecna — following the massacre as Hawkins Lab. After the Demogorgon's defeat, Eleven also disappeared and was believed to be dead, but at the end of the Stranger Things season 1, Hopper was shown leaving waffles in a box in the woods, implying that he either knew or hoped Eleven was still alive.
