Opened oneshot requests the other day and so many people requested a dark x anti oneshot. I've never been a fan of reading them but I've been thinking lately about writing one myself. Welp, here I am, sorry if it sucks :P

TW: threatening of a knife
-

The couple were on their way to Matthias' house, planning on filming some videos that the fans have all waited for since Jack said he was gonna visit LA. They were planning on recording multiple videos, jack not knowing what videos they are other than them being challenges.

They soon arrived infront of the house and put their car in park. They exited and went ahead to go knock on the door while holding hands, getting an immediate response. Matt warmed them with warm hugs and so did wade, Joey, and bryan. Mark walked towards Amanda and gave her a side hug while kissing her forehead and rubbing her pregnant belly. Amanda has grown on him like a sister eventually and he couldn't be happier for her.

Everybody stared in awe while Jack quickly moved towards the recording setup and asked what they're gonna film.

"Well, first off we're gonna play the seven second challenge, then never have I ever with jelly beans, and finally we're gonna be doing the finish my sentence challenge, or we'll do them in random order I don't know" Matt walked towards the setup making sure everything is in place and ready to record.

A few minutes after, everything was ready and almost everyone were in their seats. Matt sat down infront of the camera and hit the record button. Suddenly, Jack clapped out of nowhere and made everyone jump.

"Syncing your shit, you're welcome man" Jack winks at Matt and laughs.

"What's going on guys, I am Matthias and today I'm gathered with these lovely people" Matt raises his hands attempting to point at everyone. "Mark, Wade, and by popular demand..." Wade made a drum roll noise "JACKSEPTICEYEEEEEEEE"

Jack heard his name and popped up from under the chair while humming loudly to the John Cena theme song. Everybody in the room laughed except wade who walked out of the frame with his hands in the air but Matt made sure to drag him back.

"Amazing start! Today we're gonna be playing 'never have I ever' but with jelly beans! We have seven jelly beans and we shall start with Wade!" Matt pointed at the tall lad next to him.

"Um, never have I ever went to Ireland" Wade laughs as Jack throws a mixture of swear words in wade's way. Both Mark and Jack ate a bean and glared at Wade.

"Never have I ever kissed the same gender" Matt said. Mark and Jack came here to have a good time but honestly they feel so attacked right now. They both ate a bean, having a remainder of five left.

"Never have I ever graduated college" Mark laughed as he watched all the guys eat a bean. "Go to college kids, it's important"

"Never have I ever drunkely kissed the opposite gender" Jack laughed, watching Wade and Matt eat a bean, knowing Mark and him were in the free zone. But to Jack's surprise, Mark hesitantly put a bean in his mouth. Jack looked at him with eyes wide open. Mark noticed that and glanced at Wade, trying to signal him to continue the game.

"Never have I ever made love to the same gender" Wade wiggled his eyebrows and Matt laughed. Jack and Mark groaned again and ate another jelly bean each "is this supposed to be a love addition?" Jack asked angrily.

"Sure, we can go with that. Never have I ever sucked a dick" Jack looked questionably at Mark as both of them at a bean. "I thought you had gag reflex?" Jack questioned. "How would I know I have gag reflex if I haven't tried it, you idiot!"

"Never have I ever been married" The guys watched Matt as he ate one and frowned in defeat.

"Never have I ever dyed my hair green" Mark laughed as he watched Jack eat a bean leaving him with only one left. "Fookin douchebag, that's the only color you HAVEN'T dyed your hair!"

"Never have I ever almost died from drinking" Mark frowned as he ate another bean. "That's mean" he frowned.

"Never have I ever had a threesome" Matt and Wade widened their eyes as Mark and Jack both ate a bean, meaning they're out of the game. "Don't judge us" Mark and Jack said as they left the frame.

"Hey Mark, what's your favorite bean?" Mark wrapped his arm around Jack's shoulder and hugged him. "This guy is my favorite bean"

"Hello everybody my name is markiplier, and welcome to the seven second challenge app by Dan and Phil! Today I'm gathered with Matthias, Wade, and-"

"HIS NAME IS JACKSEPTICEYEEEEEEEEEEEE" Jack jumped into frame, specifically on Mark's lap as he also hummed the background music. "Are you just gonna do that every single time?" Everyone laughed.

"So yeah, we're gonna get right into it!" Mark pressed the play button and handed it over to Wade.

"Come up with a poem about bacon" wade said. Jack panicked and trying to think of something. "Umm, bacon, it's not made out of a bunny, I would eat it with everything, I like it in my tummy!" He raised his arms in victory. "BACON"

The guys rotated and Jack now faced Mark. "Attempt to do jumping jacks but with your hands in your pockets" Mark jumped around randomly and ended up being a stupid laughing mess.

They rotated again and Mark was now facing Matt with his phone in his hand. "Be a chair for the person with the phone" Mark got up and sat in matt's lap. Matt smirked for the camera and Mark gave Matt a side hug. Jack glared at them for a moment but decided to pass it by so that nobody would catch his infamous looks.

A rap song, backflips, wall touching, and several food poisonings later, they were officially done with the second second challenge video.

"So thank you guys-" Mark was cut from his outro to a kiss to the cheek by Wade, and Mark smiles cutely and held Wade's face to his for the camera. It's like they were doing this to annoy Jack, they knew it would flip him off and send him into oblivion with his jealousy problems. For them, apparently it's 'fun'.

Mark and Jack left shortly after, claiming Jack was 'not feeling well'. Jack said absolutely nothing the whole way back. In fact, he had his headphones in, listening to some rock band. Mark kept glancing at him every once in a while, worried, thinking he was sick.

They arrived in their driveway and Jack walked towards the door silently, not even looking at Mark. He grabs his keys from his pocket and opens the door and goes in. He feels this slight pounding pain in his head, not precisely a headache. He walks towards the window to look around so he can maybe drown his pain with the view.

Mark sneaks up behind him and wraps his arms around his face and buried his face in Jack's neck. Jack felt the pain in his head again and he grabbed his upper side of his head in his arms and clenched it tightly. Mark gave a questioning look and turned him around, asking if he was okay. He slowly raises his head from his hands, revealing his face.

Mark steps back quickly, cautious of the creature infront of him. He wasn't the normal Jack he was used to, no blue eyes, no green hair, no bright lovely smile. Instead, there was this abnormal copy of him, pitch black eyes, coal colored hair, pale skin, and devilish smile. "What are you?" Mark questions, scared.

"Oh, should've introduced myself. My name is anti, the dark side of that oh-so-precious boyfriend of yours. I come out when you keep fucking him over, and over, and over..." Jack giggles in a high-pitched voice.

Mark attempts to run back, but is pulled by something, you could say it was 'the force'. Jack had his arm raised up, and he slowly bended his fingers, bring Mark closer to him.

He kept him ahold by his shirt and brought him so close to the point that their faces were almost touching. "What a silly human, don't you know, if Jack ever gets pushed over the edge, hatred, I return? There's no escape this time. Jealousy, ah yes. Weren't you the one on matt's lap? Weren't YOU the one that kissed Amanda? Weren't you the one that kissed Wade? What a shame, dark would never do that to me, he was always such a good boy, you should've learnt some things from him" Jack giggles again.

"Return? Jack knows about you?" Mark yells.

"Ha, he never told you, did he? He was afraid he would freak you out, but what he didn't know, is that you have one too" Jack let's him go and crosses his hands together while he plays with his fingers.

"And how the hell do you know about that?" Mark asked in a rather angry tone. "Oh don't worry, I've had my little talk with that dark of yours" Jack laughs.

"You son of a bitch" Mark attempts to take a swing at Jack but misses due to him vanishing and appearing again behind him. "You really thought you could defeat him, and you did. Ignorant creature. Now, I'm gonna make your loved ones feel what I felt. You killed my boyfriend. Now Jack is gonna feel what I felt like and it's all going to be your fault" his voice glitches out.

Mark slowly felt his heart break into pieces. It was true, Mark had managed to kill dark and put him at rest, even if he was almost horribly murdered.

"Give me jack back and leave already, I don't want to fucking deal with your shit" Mark pushed Jack over, Jack getting back on his feet a second after.

"Oh, you think it's that easy don't you?" Jack said as he pinned Mark to the wall and licked from his collarbone up to his neck. Mark shivered under his touch and tried his best to get him off.

Jack glanced at the drawer and used his power to open it. A knife flew into his hand and he just stood there flinging it around with his hand.

"Now, where should we start?" Jack turns around and faces him again, but now, his right pupil is shining bright green.

"Jack, I know you're in there and I know you can fucking get out, fight him!" Mark cried, clenching his stomach and attempting to stay away as far as possible.

"Haha" Jack giggles "Jack is no longer in there, your precious little guy will be out when you're DEAD" jack laughs with his squeeking glitchy voice as he takes a fling at marks head but misses due to Mark falling on the floor. The knife levitates back into Jack's hand and he's ready to physically murder him.

"Jack, please snap out of him, if not for me, do it-" Mark fights a sob "-for the baby" he says as he clenches his stomach even harder. Suddenly, Jack's eyes start phasing from white to black in a strobe type of way.

"Y-you're pregnant?" The normal Jack asks as he snaps into reality, just to be taken over by anti shortly after. Jack puts this devilish smile on his face and moves closer to Mark. "Double the win" he laughs.

"Jack... Please..." Mark starts sobbing. Jack's eyes keep flashing between normal and dark and the normal Jack couldn't handle seeing Mark like this, in the face of death, with their baby in his belly.

"Do it for our fans, do it for whatever you love the most. Jack, please, you have to escape this!" Mark cries, trying to snap Jack back. "I fucking love you so much, we've been together through thick and thin and I don't want it to end now. We would watch our baby grow, we would watch them stumble and fall but still manage to get back up, do it for your child's-" Mark was being shut up by all the tears that were consuming him. He tucked his legs into his chest and began crying into a ball.

He could see a tear run down Jack's cheek, even in this state. For some reason, anti made his way faster to Mark but suddenly, his whole body started shaking rapidly. He clenched his head and dropped the knife, attempted to pick it back up to instantly kill Mark. He eventually manages to grab it.

He lowers his body down to Mark's level and grabs his head and lays it back to expose his neck. He slowly runs down his tongue exactly where the knife is gonna cut. "Dark was always so good, he would obey every single one of my orders and he would whimper under my touch"

"You kinky son of a bitch" Mark yells in hatred but all he receives was even a faster way to go. Jack brings the knife to his neck and gently rests it there, ready to cut him. He cuts with full force, but for some reason, it doesn't work, his hand just didn't move. He attempted again and again, but he just couldn't, something was holding him back.

He got up quickly and felt himself lose consciousness. He drops the knife and slowly drops down the floor. He lays there, fast asleep. Mark stares at him while the sobs echo in the room.

A couple of seconds later, Mark noticed his eyes open, but this time, they were normal blue. Jack's eyes widened as he quickly gets up and drops next to Mark as he places him in his lap and hugs him tightly.

"I'm sorry, I'm sorry, I'm sorry" Jack repeats as Mark sobs into his shirt. "I love you so fucking much, I'm so sorry he did this to you, I'm so fucking sorry" Jack says inbetween kisses.

Mark just lays in Jack's arms and he eventually stops crying. "So, we're having a baby?" Jack smiles looking into Mark's eyes. "Yes we are" Jack kisses Mark's forehead and then his belly.

"So, wanna go play video games?"
