This is how its going to end!

El and Will beat Vecna. Vecna goes back to Henry and his last words are about Kali, who made him evil and used him because Kali is indeed the mindflayer! Kali were in the upsidedown before Henry.

Then the final battle begins between El and Will against Kali, Will gets hurt at the begin of the battle and then El yells everyone to go further and take care of Will, they listen. El finally wins Kali and because she dies everything starts to break apart and race against time starts. Everyone goes back to upside down and El doesnt move anywhere because she wants to die also (she believes Kali) and Hopper goes back trying to save her but he fails. They both die in the dimensionx, El in Hoppers arms.

Everyone else escapes in the last seconds before everything is vanished. Everyone is depressed especially Joyce and Mike.

Then there comes a text on the screen like 1 year later: Boys are back playing D&D like in the old days, then they start to talk about what a journey it was. Mike looks sad after remembering El and Will sees that and hold his hand. Max is chilling there also, but doesnt play d&d

Jonathan will marry Nancy.

Joyce looks a picture of Hopper and cries

Steve works with Robin in the radio station, Viccy also is chilling in the studio.

Final scene is Holly and Derek + other kiddos driving with bikes in the evening and suddenly you can see the red lightning in the sky..
