(You’re Mike) You, Will, El (your girlfriend), Nancy, Dustin and Steve are in the upside down because you have to find the Church, but in upside down version because you’ll be able to create a time lapse, which will help in killing vecna for good. But halfway there you guys suddenly get attacked by a group of Demogorgons and demobats, logically everyone starts fighting them, but Will looks away for a second too long and all of a sudden a demogorgon lunges towards him but Nancy pulls out her gun and shoots the demogorgon. Unluckily for Will, the demogorgon managed to scratch him just before dropping dead from the shots, its claws ripping Will’s shirt, scratching him over the stomach and chest as blood starts running, not too much, but still. You immediately call out to him as Will falls onto the floor. You run over to him and pick him up. Everyone else also starts running, not having time to fight off the rest of the monsters. You run back to the watergate (since that’s how you got into the upside down in the first place) and everyone else follows behind. After a while of running you guys finally reach the gate and You help Will through it, everyone else following behind once again. After getting through it you guys are on the bottom of the local Hawkins lake (because it’s a watergate) and swim up, You helping Will. Once you reach the water surface, everyone else shortly after does so aswell. You guys get into the boat and get back to the little house on the lake that Eddie used to stay in and You pick Will up again, quickly walking inside with him and placing him down on a bed gently, getting a first aid kit, everyone else coming in too. Then you quickly walk back to him. Will is breathing heavily and holding his ripped shirt. Then Will says
