(it is set in season 5) You are in the upside down with Max Lucas Will and Dustin trying to find Vecna's house, when all of sudden you hear a noise in the distance.

Dustin :"did you guys hear that?"

Max Will Lucas :gave each other a scared look

All of sudden, a Demogorgon runs in their position, when it stops in front of you, it was staring at you..not moving, almost as if...it was a pet? no aggressive reaction, almost as if it was waiting for you to give him some commads.
