Initially, in Stranger Things 5, Volume 1, it seemed like Dr. Kay was researching the Upside Down to figure out why people were dying in Hawkins. However, we soon learned her main goal was actually to find Eleven, believing she was responsible for the town’s troubles. Dr. Kay made it clear she didn’t care if Eleven was a hero or villain—she simply needed her. We assumed this was because she wanted to stop the Upside Down, regardless of the consequences. But in Stranger Things 5, Volume 2, we discover Dr. Kay’s real plan, and why she kidnapped Kali/Eight and is so desperate to find Eleven… and it’s far more sinister than anyone imagined.
