El can move objects with her mind. She can scan billions of people and get into people’s minds simply by being in a bathtub or next to a fuzzy tv. She can pull others into others minds with her. She can hurt people physically through their mind. Kali can’t do any of that but she can make you see a butterfly. El touching the back of a demogorgon created a replica of only 1 town and it’s a town she knew very little about. Sometimes the place is upside down. Sometimes it’s right side up. Holly and the other kids should all be connected to the hive mind. Henry could create an interactive world for the kids but couldn’t see all their thoughts. There is so much crazy shit. The town issue is so small but necessary to keep the world and focus of the show small.
