(y/n) - your name

(b/n) - brothers name

"Should we wake them up?"

"No!"

"From my experience with (y/n) being absolutely terrifying when we wake her up early in the morning... definitely not!"

"But we need everyone-"

"-we can just talk about it between us-"

"-but it involves her brother-"

"-you guys are a bunch of pussies. How bad can it be to wake them up?"

"Mike don't! She's gonna eat you alive!"

(y/n) groans out hearing incoherent whispers, picking up on the door opening and the creak of the floorboards. She turns her head, her vision clearing to see a bunch of kids in her room. They stared at her with wide eyes, like frozen deer in front of headlights.

"You woke her up!"

"How did she wake up so easily!? Does she have sharp hearing!?"

"What the fuck are you doing in my room!?" (y/n) hisses out, leaning up from Billy's chest she was sleeping on

"Oh. My. God." the kids exclaim, looking down and (y/n) does the same, gasping as she notices that her and Billy were both naked.

"Get out!" (y/n) screams as she pulls the blanket over her, thanking God that the kids mostly saw her exposed back as they ran away. She sighs in frustration, dropping her head back down on Billy's chest. "For fucks sake... how did they get in? I took away the spare key-Max and Eleven, goddamnit..."

"Morning darling..." Billy yawns out as he rubs her back, opening his eyes to see her lying on top of him. "What's wrong?" he felt her nuzzle his chest, sighing out.

"The kids..." her voice muffles against him as she kisses his chest and he looks over at the open doorway, growing furious.

"Those fucking shitheads are gonna get it now!"

~~~~~~~~

"You little shits need to learn something called privacy and boundaries!" (y/n) hisses out as she sets some snacks and food down for the group of kids that were sitting in a circle in her living room. They said thank you, avoiding looking (y/n) in the eye as she sat down next to Max on the couch, Billy looming near with a death glare.

"Sorry (y/n), sorry Billy."

"Good, now why did you all just camp out here in my house? What did you need to wake me up for?"

"The Mind Flayer is back." Will says, wringing his fingers together and (y/n) and Billy look at each other.

"We had a feeling." The kids look at Billy in shock as he sits down next to (y/n).

"But you guys explain first." (y/n) sips her tear and Will nods.

"I didn't think it was anything at first. I mean, I think I just didn't want to believe it. The first time I felt it was at Day of the Dead."

"Power went out that night, too." Mike points out.

"I actually got a bad feeling too. We were on our date where the lights were flickering in the restaurant bathroom." (y/n) speaks up.

"You did, why didn't you tell me?" Billy says and (y/n) shrugs.

"My instincts aren't that great. I thought I was just sick or something, or nervous..."

"And then I felt it again at the field near the Nelson farm the next day. Then again yesterday outside Castle Byers." Will continues.

"What does it feel like?" Max asks.

"It's almost like... You know when you drop on a roller coaster?" some of the kids said yes and no, (y/n) shaking her head no while Billy said yes.

"You've never been on a rollercoaster!?" He whispers to her.

"I'm fucking terrified of them so no!"

"So you never go to amusement parks?"

"I do, but I'm the designated holder. Hold people's stuff while they go on rides cause there's nothing for me to do there."

"That's just sad."

"Shut up you ass." (y/n) elbows Billy lightly and the two go back to listening to Will explain the feeling and how it was connected to how close the Mind Flayer is.

"I closed the gate..." Eleven says.

"I know, but... what if he never left? What if we locked him out here with us?"

"There's a piece of him that we locked here in Hawkins with us..." (y/n) mumbles out and the kids look at her. "We were coming home one night when something caused Billy's car to crash. I had that same bad feeling in the restaurant then."

"We heard screeching and growling-"

"-and when Billy managed to get the car working again and we backed out-"

"-something came out to grab us. Like a vine or a claw, or something bloody."

"It was too dark to see but there's something in that abandoned factory on the way to Mike's place." Will looks at (y/n), quickly taking out some paper and charcoal.

"This is him." He was drawing furiously on the paper with the charcoal. "But, that day on the field, a part of him attached itself to me." Will swipes his hand across the drawing to get charcoal on his skin. "My mom got it out of me... and Eleven closed the gate."

"But that piece that was in you is stuck in our world..." (y/n) sighs out, her leg bouncing up at down anxiously.

"I don't understand. The demo-dogs died when El closed the gate. If the brain dies, the body dies."

"But this piece is part of the original brain so it will act like the brain. It needs hosts... to build an army..." Billy whispers, looking at (y/n) as he rubbed his hand on her leg that was bouncing.

"I think it got Heather and my brother..." the boys look at (y/n) in confusion about the brother part. "Oh my god, it got my brother..." Billy quickly takes (y/n) away as she starts crying, the kids looking at each other.

"(y/n) has a brother!?" The boys exclaim.

"She didn't say much but yeah. El and I saw him in Heather's place." Max says.

"How did you know it was her brother?"

"(y/n) showed us a picture." Eleven points out to the photo that sat on the table and the boys lean over to take a look.

~~~~~~~~

"Holy shit it really is him..." The kids watch as they see this tall ass guy they have never seen around Hawkins before walk out of Heather's house with her and get in a car, driving off.

"That's (y/n)'s brother!" Mike exclaims. "Wait, where's Max-Max!" she was sneaking across the road to the Holloway house, pushing the door that creaks open.

"Let's go!" Max calls out, signally the group to run over and they do, heading inside the house quickly before anyone could see them.

"Why are we in here!?" Lucas squeaks.

"We need proof, proof that the Mind Flayer got Heather and (y/n)'s brother." Mike snaps. Will quickly looks around for the bathroom, knowing exactly what the Mind Flayer likes.

"Guys!" he calls for them and they all rush in to see the bathtub filled with ice and cold water. "The Mind Flayer likes it cold..."

"Well, shit..."

"Let's follow them." Mike suggests.

"Where would they be though?" Mike asks.

"Pools!" Max and Eleven point out.

"Heather works at the pools with my brother!"

"Ok then let's go!" the kids run out of the house, getting on their cycles and trekking it down to the public pools. They throw their bikes behind some cars, spying on Heather and The Brother with Lucas' binoculars.

"They're just lounging at the pool, which is, like, the least Mind Flayer thing ever." Max says as she sees Heather doing her job as the guard but wearing more clothes than she usually does. The Brother was also there, chilling out under one of the umbrella chairs.

"Not necessarily." The kids look at Will. "The Mind Flayer likes to hide. He only used me when he needed me." explaining how he was dormant when he wasn't being used but activated when the Mind Flayer needed his body.

"Okay, so we just... wait until she gets activated." Max says.

"No." Mike quickly responds, saying how they could hurt or kill someone. "We can't take that chance. I have an idea. Boys only." the guys walk off, heading to the men's shower room.

"Shouldn't we tell (y/n)? This is her brother. She would want to be a part of this or at least help." Will asks.

"We don't have enough time!"

~~~~~~~~

"Oi, you little shits!" Billy hisses out as he and (y/n) run into the sauna room that Max led them to, Eleven and the boys enacting their plan to capture one of the hosts. Unfortunately, they lost Heather but they managed to fool the other Mind Flayer host.

"(b/n)..." (y/n) gasps out, seeing her brother for the first time after a couple of months. "What are you guys doing to him!?" she screams out but the boys keep her away from the door her brother pounded against.

"(y/n)..." her brother whispers and everyone looks at her, Billy holding her back.

"Do it." Mike says and Will turns up the heat. 

"(y/n)! Let me out of here! Let me out please!" (b/n) screams out. "Please (y/n)! I missed you! You just left without a word and I missed you so much! I hadn't seen you for months and I needed to find you! I needed my big sister, I needed you!"

"(b/n) I'm sorry!" (y/n) falls to her knees as she hears her younger brother screaming for her.

"I left mum and dad to find you! Left them like you left us because I needed you! I needed you! I missed you! (y/n), open the door, please! I want to go home, take me home! Come home with me! Come back!"

"I'm sorry, I'm sorry!" (y/n) cries out, hearing her little brother sob.

"I've done things, (y/n). Really... bad things. I didn't mean to. He made me do it."

"Who made you do it?" Max asks out, stepping towards the window of the door.

"I don't know, it's like a shadow. Like a giant shadow. Please, (y/n)." She stands up and walks towards the door, gently moving Max away.

"What did he make you do?" she asks her little brother, hating how much pain he was in.

"Please, believe me, (y/n), it's not my fault. I tried to stop him, okay? I did!" (y/n) breaks down, leaning her hand against the window.

"It's gonna be okay. We're gonna get that thing out of you. I'm so sorry for leaving you, I'm so sorry (b/n). Please forgive me!"

"(y/n), get away from the door!" Mike yells out and Billy runs over to pull (y/n) back as she screams, the window on the door shattering as her brother breaks it.
