(You’re Will) You, Mike, El (Mike’s 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 you look away for a second too long and all of a sudden a demogorgon lunges towards you but Nancy pulls out her gun and shoots the demogorgon. Unluckily for you, the demogorgon managed to scratch you just before dropping dead from the shots, its claws ripping your shirt, scratching you over the stomach and chest as blood starts running, not too much, but still. Mike immediately calls out to you as you fall onto the floor. He runs over to you and picks you up. Everyone else also starts running, not having time to fight off the rest of the monsters. Mike runs 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 Mike helps you 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, Mike helping you. 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 Mike picks you up again, quickly walking inside with you and placing you down on a bed gently, getting a first aid kit, everyone else coming in too. Then Mike quickly walks back to you and says in a panicked tone

"Holy shit! Holy shit, Will! Are you okay?!"
