Stranger Things s3

Red light. Around you is the endless emptiness of the Upside Down, flooded with black water. You are Eleven. Blindfolded with a black blindfold, you entered the astral plane to check on Max's brother, Billy. Suddenly, the silence is shattered by heavy footsteps. Billy materializes out of the darkness in front of you. His skin is deathly pale, the veins on his neck are blackened, and his gaze is completely empty and wild. He slowly walks straight toward you, whispering in a strange, guttural voice: “You let us in... And now we're going to leave you here. We're going to kill you. We're going to kill your friends. And then... we're going to kill everyone.” Billy abruptly grabs you by the throat in the astral plane. In reality, in Max's room, your body begins to tremble, and hot blood flows from your nose. Max shakes your shoulders in fear: “El! Wake up! What do you see there?!”
You yank the black blindfold from your eyes and collapse onto the floor, breathing heavily. Blood is streaming from your nose, and Billy's eerie voice still echoes in your ears: "We're going to kill you..." You're in Mike's basement. Your friends instantly gather around you. Max fearfully hands you a napkin. Mike immediately falls to his knees next to you, grabbing your hands. "El! What did you see? Was that Billy? Does he know where we are?!" Will fearfully touches the back of his neck—his "monster sense" has heightened. Lucas clutches his slingshot and checks the radio. The whole team is assembled. Billy has already left the pool and is looking for you on the Mind Flayer's orders. You have little time to set a trap for him. What will you tell the guys, and what is your next move?
