Jekyll/Hyde X Reader

Billy will leave

Hyde's POV

After Henry tells me he'll make a potion for me, we both fall asleep.

Something begins to form, a light, then I see my feet, then I look around, it's pitch black, but I'm standing. While I look around for some source of light I suddenly feel water on my feet, looking down, there is water. Though, the water is a blood red color, my feet are a few centimeters submerged in this blood-colored water. Suddenly the water slightly vibrates, I watch the small ripples, but then the lake flips upside-down and I begin drowning! I grab my neck in fear of losing the air inside me, while I'm upside-down trying to breathe someone grabs my foot and I look at them.

Billy is the one who grabbed me! But, when he's touching me I can breathe. "Wh-What do you want?!" I yell to him.

"I want out Edward. I want outside of our head. I want to run around London like the Spirit of London Night that I am!!!"

"You know I can't let that happen!"

"Then I'll just have to continue adding to this lake of blood. Let's see, I think Daddy is next."

"No... No don't YOU DARE TOUCH HENRY!!!"

"Maybe it's too late for that"

"I SWEAR BILLY IF YOU DA-" Billy lets me go and kicks me further. I begin drowning again, trying to swim to him so I can breathe, but he shoots up and out, and watches me drown from above.

I grab my neck once more trying to breathe, but soon I get very weak.. my vision begins to go fuzzy and dark. I can't think straight. All I can think about is Henry.

"Edward" My eyes open a little as I hear Henry's voice. I look to my right as I sink, Billy is back inside the blood lake and he has Jekyll. Billy takes a large knife and slits Jekyll's throat!

I sit up suddenly breathing hard in a cold sweat.

"Edward!" Henry says next to me, and I look to him. "Are you alright? You started grabbing your neck tightly and made choking noises, then you started sweating horribly! You weren't breathing! I almost called Poole to get Y/N." Henry looks incredibly pale and worried. "What in the name of science did you dream about?!"

"I-I.... it was Billy. He was drowning me in a lake of blood, then he killed you.. I was so scared.. I couldn't breathe unless he touched me.. H-Henry.. will I not be able to breathe if we kill him?" I look at Henry worriedly.

"No.. No of course you'll be able to breathe."

"B-But what if that nightmare meant that I would die when he does?"

"It didn't. Billy is just scaring you. I promise he's only trying to scare you."

I stay quiet for a moment and look in front of me. I look around the dark room, making sure that this is all reality and not still a dream. Looking at a wall, I notice some blood leaking from it. Suddenly I can't breathe again and I grab my neck, beginning to choke, it hurts the way I'm being choked, like someone is crushing my neck in the process.

"You'll die without me!!!" I hear Billy's voice say.

Then suddenly I can breathe again, I hyperventilate for a few moments, then look to Henry again.

"I'll continue the potion now." Henry stands, then I stand and follow him down to the lab. Henry mixes multiple chemicals and a few edible plants into the flask and let it boil. After a few minutes it turns to a purple. "Alright, it's ready."

"H-Henry... I.."

"What's wrong?"

"I don't want to take it..."

"What?! Edward are you mad?!"

"I don't know! But I don't want it! I could die!"

"Have you really come to that conclusion?"

"But the dreams, and Billy, and not long ago even after I was awake he started choking me again, and he said that I'll die without him! I'm scared!"

"I understand you're scared but killing Billy is the right thing to do." Henry gets on his knees sitting in front of me (I'm sitting on the floor). "Edward you won't die. I promise you you won't. Billy is only trying to scare you, and the longer you keep him inside, the more he'll torture you, the more he'll fight to be free. You can't keep him locked up forever. He will force control if he gets the chance.."

"I-I... I don't know... I-AGH" I fall back in pain.

"Edward!!"

I groan in pain for a moment, then sit back up, slouched, after it's over. 

"Edward. It's for the best if he dies. Then it'll all finally be over. He can stop torturing you."

I stare at the ground, then at the potion, then finally I look at Henry. When I look at Henry I feel like it's more than the right thing to do. So I stare at him while I say, "Okay.. I'll take it. I'll get rid of him." Henry smiles and hands me the potion, I look at it for a moment, then lift the rim to my lips and drink it. It's a warm liquid, fairly smooth, but not like a slimy substance. It tastes fairly good, kind of like cherry. "Why does it taste like this?"

"I thought I'd let you at least taste something nice."

I smile at his comment, but that smile turns into a look of shock within seconds and a pain hits me. "H-Henry it hurts. I-I feel a bit of a pain.."

"I know Edward I know. It will hurt a little because it's getting rid of the evil inside you. It's getting rid of Billy. And I do deeply apologize about the pain."

"I-AGHH!!!" I lie back.

Jekyll's POV

Edward lies on his back as he screams in a pain that is difficult to imagine, but looks similar to when I first had the potion and brought Edward into this world. I get to the side of him and try to calm him down.

"H-HENRY IT H-HURTS-AGH" Edward continues to scream in pain, and I watch as his eyes flicker between two colors. His eyes are showing that Billy is being destroyed.

"It'll be okay Edward! Billy is leaving! You'll never see or hear him again!"

Edward screams in pain on the floor as he squirms trying to escape it. I try my best to help but it's hard when he's hurting so much.. 
Soon enough, the pain begins to leave him, and he begins to breathe heavily. I slowly turn him to see his exhausted expression. "I'm so sorry you had to go through so much pain" I say, then I lift Edward into my arms on the floor and hold him while he breathes. After a few minutes, Edward places one arm weakly around my shoulder as if he's trying to hug me. I help him a little by lifting him, and he gets a better grip, placing his face into my chest and keeping that arm around my shoulder.
