The reactor is back, and a group of men are eagerly anticipating using it all over again to open the portal to the Upside Down. 

Two of them have a key each, and manage to open it. A monster starts slithering out, but the machine starts to malfunction. 

Everyone looks on in horror as the portal to the other side closes, but not before the machine sends electricity flying out, turning everyone within the distance of it to ashes.

One year later. 

Mike is singing, and Eleven wants him to stop. They kiss. Hopper watches on outside, and realizes what is going on.
