KAS The Bloody Handed

The Upside Down

Your POV

You set up in a large room of the warehouse. There happened to be a few chairs there that you used to tie Eddie down with. You asked El if you can be the one to tie him but everyone agreed that probably wasn't best.. because of your love for him you might not do it tight enough. Your argument was that with his newfound superhuman strength, no matter who ties him might not be enough anyway.
"You'd love that wouldn't you Y/N" smirked Eddie.
You shoot him a half smile.. not being able to hide the pain. It was only a precaution bounding him anyway - El was also going to restrain him with her powers.
Steve took the reigns and wrapped Nylon cord around Eddie and the chair, leaving his left hand free. Well this was stupid; he could rip apart the cord with Vecnas hand if he wanted to. No.. El was strong enough. You had to believe it.
"Everyone ready?" Eddie asked, "I'm sorry if I do or say anything awful.. know that I don't mean it".
El turned towards Eddie, her head hanging low and held her hand out in front of her. No one knows how her powers work, but you all believe in her.
Eddie drew upon his new found powers and you watched in complete fascination. His left arm and hand started twisting and bubbling, turning red, and giving you horrific flashbacks. It's ok. This is Eddie. Not Vecna. It was kinda hard to distinguish between the two when his hand was literally turning into Vecnas though. His fingers elongated and sharp black claws grew from his fingertips.
As soon as the hand transformation was completed, El called upon her powers and restrained him. This made his supernatural instincts kick in and you watched as his eyes turned a dark shade of purple and his demeanour completely changed. He didn't look like your Eddie. And he certainly didn't sound like your Eddie.
"Let me go you fucking bitch!" He snarled at El, frothing at the mouth like a rabid dog. He carried on spitting profanities out as Els powers forced his 'Vecna' hand up towards his face. You could feel the power emanating from him and you were worried he was going to snap out of the hold El had on him. She left his hand lingering over his face for what felt like a lifetime... nothing happened. There was just an angry Eddie, with a messed up hand covering his face- in different circumstances this would have been quite funny.
El decided to stop before she drained herself. She walked around Eddie, stood behind him and placed both hands on either side of his face. You watched as his eyes turned from a deep dark plum colour to the colour of lavender.
"Thanks El.." he sighed.
"So what now?" Asked Steve.
"I think it has to be a voluntary thing.. not forced" explained El, "maybe talking about you know who whilst Eddie is bound might work?".
El once again used her powers to subdue Eddie whilst Steve and Dustin started yelling random things about Vecna at him.
"Vecna killed you Eddie, took you away from us all!"
"Vecna killed your friends!"
"Vecna is going to kill Y/N"
That last one seemed to make Eddie snap. He let out a low, rumbling growl that vibrated through his body.
"I'm going to kill you all" he said so calmly, it was nerve wracking.
Eddie looked at you, those disturbing pitch black eyes burying into your soul, and just when you thought you couldn't take anymore.. He disappeared. The nylon rope that tied him down fell around the chair in a silent cluster.
"Well.. think that pissed him off?" Half joked Dustin.
"We never discussed what was going to happen when he comes back... what if.. he comes back worse? Or reset?" Asked Robin.
Shit. How did none of you think of that? You had another question to add onto Robins that you didn't say aloud. What if he doesn't come back at all? Well, considering the big mess you all made of things, you had no other option but to wait things out. Steve decided it was best for you all to stay together, at least until Eddie came back. It was also decided to head back to Mikes as you couldn't be sure that Eddie would reappear at the Warehouse. Just as you were all leaving the Warehouse, you turned around and took one last look at the spot where Eddie was sitting... and silently prayed.

Eddie's POV

Eddie blinked. He's sure that's all he did, yet in that split second he was transported to the Upside Down. How the hell did that happen? He felt angry.. no, not angry.. outraged. He wanted to kill something. Someone. He didn't have El to calm him this time. The instant he landed in the Upside Down he remembered everything. He had been here for a year, training.. learning how to hunt, to kill, to feed. Vecna had made him a warrior, teaching him how to use his new powers. He remembered the sadness at first, and how Vecna slowly took away all of his emotions until he felt nothing but fear and anger. Fear of Vecna... he was to always be feared. And anger at everyone else.. his friends; for leaving him, for allowing him to die. They never cared about him. Y/N never loved him. It was all lies. He was used as bait and nothing more.  He was nothing.
Looking around he could see that he was still in the Warehouse, but this place was covered in black sticky vines. Everything looked dead.
"Well, it's time to go and find that bald bastard" he mused out loud. It shouldn't be too hard, he's probably chilling at his house. The thought of Vecna 'chilling' brought a smile to Eddie's mouth. Huh... maybe he could calm himself down, with silly thoughts? He certainly felt a little bit better. He hopped up and made his way out of the Warehouse. Taking a deep, steadying breath, he sped to the house of Victor Creel. It took him less than 30 seconds.
He didn't bother knocking, he just waltzed straight in and up the stairs towards the attic. The sight that befell him when he entered terrified and amazed him. Vecna was suspended high in the air, his weird slimy tentacles sprouted at every angle. This was the stance he usually took when hunting his own victims.. but even after a year he wasn't strong enough yet; that's why he took Eddie under his wing... to do his bidding until he was strong enough to come back.
Eddie just stood and stared at Vecna, remembering why he was there. This supernatural being was the reason that Eddie was 'alive'. He could never betray him. He would do anything for him. His emotions were running wild; a mix of loyalty and love with fear, anger and resentment. He didn't want to feel this way towards Vecna, but his mind and heart would not let him feel otherwise. He owed this being his life. Eddie fell to his knees in surrender and waited for Vecna to acknowledge him.
Vecna slowly opened his eyes and stared down at the inferior being below him. Why was he here? He hasn't fulfilled his mission. Pathetic.
"What do you want" growled Vecna.
"I need some guidance Master" Eddie heard himself say, "I need some true understanding of myself, my task, and my travels".
"The fact that you are back means you have failed. I will share my knowledge with you, and you will not fail me again" Vecnas sinister words trilled through Eddie's ears, the unspoken threat very clear.
"Yes Master" he replied eagerly, "I promise you I will bring back not only HER dead corpse, but those of her friends too".
