AN: Inspired by watching Mark's Markiplier TV, I've had this sort of story in my head for a long time, originally not as a fanfic but I wanted it to come to life in some shape or form. So before I continue I wanna say that I have done a lot of research in terms of the mental condition, Dissociative Identity Disorder, and have had experiences with people diagnosed with it. But I do apologize if I offend anyone with it or to whom has more knowledge about it, and I am certainly not trying to disregard it as something fictional. For the sake of this story however it will be fantastical and exaggerated for plotline purposes. And the personalities will be a little out of character, as I am using Mark's actual characters (i.e. Dark of course and Wilford, etc) and want it to fit in certain personality patterns and roles I have noticed in people with D.I.D. I also will be giving some of them human names or nicknames cause ya know, it's easier. I also am a supporter of both Jack and Mark's relationships, but I'm such a fan of Septiplier I can't help it. So without further adieu, enjoy!

He hadn't noticed it at first, how the brunette sometimes acted a little off when they played a game or whenever he watched his videos; sometimes even when they met up in real life. He would act unusual, nervous or even very chaotic; which was not something the trademark gamer that 17 Million people knew him was like. He thought it was just stress getting to his friend, but this was something completely different. It had come to his attention that this thing the American was dealing with, force to deal with really, had apparently been a prominent problem in his life whether or not the 27 year old knew it himself. The Irishman wasn't stupid; he was keen on change whenever it came to his friends, so the fact that said friend had no clue what was going on worried him even more.

But here he was, playing games with him as if nothing were wrong and all was right in the world. With loud screaming blasting from his headphones, the green haired man couldn't help but giggle. It was nice, to be in a short lived reality where he didn't have to suspect the obvious thing tugging at his mind lately. Nothing in particular set it off; not really anyway. It was just something Jack had noticed last time he talked to his fellow YouTuber. Ever since then it had become a nagging thought ceasing to leave. He was concerned, in a position where he wasn't entirely sure what he could do or if he should talk to Mark about what he was so perplexed about. But nonetheless he didn't want to focus on it at the moment, hoping it really was just what he suspected it to be.

"Fookin' hell Mark, " he retorted, watching Mark dying once again and howling in laughter as his frustrated friend grumble a string of curses at his attempts.

"Well whatever!" The other finally said, huffing out and pushing himself away from the keyboard.

"Alright, that's all the time we have left. Thank you guys for watching and as well always, I will see you all in the next video, ba bye!"

Jack in turn did his own outro and switch off the recording, still connected to Mark via video messaging.

"So we still on for tomorrow?" He asked, grinning excitedly. He loved playing games with his friends, not to mention Mark who had become a big part of his own life recently.

"Of course! I have shit to do earlier but same time as today and I'm all yours," Mark replied, smiling back as well. Jack couldn't help but let his mood falter slightly, not knowing why exactly. There it was again, pounding against the walls of his mind.

"Hey um, Mark," he started, gulping nervously. He could feel his chest sink, debating whether or not to ask him the question that racked his brain perpetually. He trailed off and left the american confused, opening his mouth to say something but nothing coming out. Mark waited patiently, growing slightly anxious at the ongoing silence from his best friend.

"Everything okay, Jack?" He asked softly, kind as he ever was. This brought comfort to Jack, but it didn't suppress his disconcert for the older man.

"Yeah, um, it's nothing don't worry about it."

He decided not to bring it up now: they were having such a nice evening and he didn't want to ruin it by asking something so silly. It was just in his head that there was something wrong, even if admittedly Jack himself didn't know what exactly was wrong, he just knew something strange was going on.

"Oh, okay, well you can talk to me about anything you know," he replied smoothly, showing his sunny smile on the camera to the Irishman.

"Thanks, sorry," Jack chuckled, rubbing the back of his neck. The way Mark was smiling at him however seemed weird to him, not quite "Mark" if that made sense. Almost forced, not matching his eyes which looked more serious. Taking a deep breath, Jack said his goodbyes and exited out of the video chat, sitting in his chair for a long moment. It was getting late here, so maybe after a good night sleep things would work out.

The next morning went on normally as expected, making his daily video, editing most of it, and spending mindless time messing around on the internet. Just a calm, relaxing start to the day in good old Ireland. Jack noted to himself that he should probably go to the corner market to pick up some things for dinner, and grabbed his keys, wallet, and jacket. He had lunch plans with an old time friend of his who was passing by Ireland to get back home in England, and decided to at least visit him on his way. It had been far too long since he last saw Felix, and was happy to have the interaction with the Swede. He also had to remember that he and Mark were going to play games later, when the older man got up anyway. So the small 27 year old walked past his car and strided listlessly down the busy sidewalks of Dublin. It was cloudy as usual, but that wasn't anything new in this country. He was happy that it was starting to get warmer, seeing as Spring was on it's way and he couldn't have been more relieved. Not that the gamer minded the winter much, he just preferred it not to get so cold his balls were literally freezing off. True that if he were cold enough he could have taken his car, but it was such a short walk he saw no reason to anyway.

He browsed the store wistful as he gathered what he needed. Maybe he should make a care package for Mark, just as a reminder that he was thinking of his friend and hoped it would help him relax a little. Perplexed by this idea, the small man cheerfully searched from items he figured would bring comfort to the other, wondering what else he could do. He wasn't sure, but lately along with worry he felt this bubbly leap in his chest at the thought of the American YouTuber, figuring it was nothing to focus too much on since he and Mark had been friends for several years now. Once he bought all the items necessary, he went straight home and got ready for his lunch date. Luckily he was getting picked up, which meant more time spending with Felix which he always liked.

"There you are, I was wondering when you'd show," Jack mocked, sliding in the passenger's seat of the rental car. The sandy blonde just rolled his eyes yet gave a friendly smile at the Irishman, chuckling.

"I mean, I just got here man," he replied softly, turning back onto the street.

"How you liking Ireland?"

"It fucking sucks, but not as bad as your horrendous face," Felix jibed back, obvious tease in his voice. The two friends shared a laugh and sat in a comfortable content sheen of quietness.

"Alright, where to cabbie?" The green haired man asked, giggling when the Swedish YouTuber snorted and yipped a "hey" at him.

"Like fuck if I know, I don't go to Dublin bro. You tell me."

Playfully defeated, Jack directed him to his personal favourite restaurant in the city, fortunately finding a parking spot in the bustling streets. The pair went inside and were lead to a booth where they sat and scanned over the menu.

"How was Greece?" The younger asked, deciding what he wanted and attempting to start up a conversation.

"It was so gorgeous, the hotel Marzia and I got was amazing and this this weird sort of indoor/outdoor pool thing. It was really nice actually, but I liked it a lot. I would absolutely go there again. How's it going for you?" Felix asked in return, setting his menu down.

"Well pretty good, although…"

Would it be a good idea to confine in Felix about his concerns for Mark?

"Has Mark been acting weird to you at all?" He finished, pursing his lips in a straight line. The swede took a minute to think over and shook his head, cocking an eyebrow at him.

"Not that I know. Why, did something happen?"

"I dunno man, I don't think so but he seems kinda depressed lately actually. Just curious if you knew what was up," Jack shrugged, trying to be nonchalant about it.

"Last time I talked to him he was telling me about probably going to a therapist. He's always been kinda weird, you know what I mean?"

This was true, he'd known Mark was easily depressed and sensitive to certain things, not to mention rarely talked about his past. But it was never brought up in conversation anyway, so Jack hadn't bothered to ask. He'd seen a strange progression throughout the years in his friend, not becoming anything alarming until just recently, especially when he watched a video of Mark freaking out whilst playing a Mario Maker game. Again, Jack only hoped it was stress that was bothering the American.

"Yeah true, I guess I'm paranoid for nothing then, huh?"

Felix shrugged in turn, relaying to the waitress what they both wanted before turning his attention back to the smaller male.

"That's not a bad thing. Why not ask him about?"

"I tried to last night but I was too chicken shit. I hate causing drama."

"It's not drama, dude," the blonde laughed lightly, leaning back in the cushioned chair and sliding a lopsided smile into his face. "Not if it's serious shit."

"But I don't know if it's actually anything serious. It must be if he's got a fucking therapist," he argued, sipping his water.

"Try talking to him then, I don't know what else to tell you. And if he doesn't wanna talk then there's not a lot we can do."

He deeply appreciated how calmly Felix was about this while the Irishman was over in the corner freaking out. It was reassuring to have him around as the voice of reason, not that Jack often asked for his opinion on things. That would just make the blonde 27 year old even more cocky than he acted.

"Hey, is everything okay with you guys?" Felix suddenly asked, smirking suggestively at him. Of course, Jack didn't understand exactly what was meant by that but decided to shrug it off as a playful poke.

"Yeah? Has he said anything mean about me?"

"That your accent is stupid and you're Irish," he bursted out laughing, digging into the food when it was brought to them.

"But just noticing things between you two, that's all," Felix interjected with a mouth full of sausage and veggies.

"Are you a damn Septiplier fan too?" The other joked, lightly kicking him under the table.

"Damn right I am, biggest one of them all."

Jack thought long and hard about his unnecessary prattling over their friend and decided to get back on that later and switch to another subject. Not long after they finished up their meal and cleaned up, saying their thank yous and getting into the car.

"Thanks for lunch, get home safe okay?" Jack waved goodbye, watching the Swede leave and wave back, zipping away. He got inside and collapsed on the couch, switching on the telly as background noise. Since when did he do nothing but think of Mark lately? It was like he couldn't help it. Obviously he wanted his friend to be alright but to an extent that he himself was causing so much stress over nothing; well hopefully nothing. He wasn't some smitten teenage girl or some stupid shit like that, he roused to himself.

Speaking of the gamer, Jack checked the time and got on his desktop, loading everything and sending a quick text to Mark to see if he was up. Much to his dismay he didn't seem to be yet, but the younger wasn't in an any hurry. After an hour had passed he finally got a message back from a half awake Markiplier, taking a while to finally get himself situated.

"Hey, sorry about that, I uh, kind of overslept.." he yawned, making loud obnoxious noises into the mic that made Jack snicker.

"Oh, no problem Mark, what should we play?"

Hearing a melodic hum from the other side, the brunette clicked his tongue in thought.

"How abooout, Bloody Death Trap?" He suggested.

"Yeah! Sounds like fun!"

As they got ready they contemplated whether or not just to do it for fun or make a video about it, and went against it. Tonight would be just their personal fun day, it wasn't often the two boys got to play games together anymore.

He was just glad everything finally seemed to be back to normal.

-What was that sound?

Jack opened his eyes slightly, his mind jogging itself awake and making him aware that his phone was crying out at him. Clumsily he grabbed at it, making several attempts to swipe the screen as the bright light blinded his vision momentarily.

"Hello?" He croaked, leaning up on his elbows.

"Jacky, thank god you answered."

Now less groggy, the green haired 27 year old fully sat up on his bed, rubbing his eyes.

"Mark? What's wrong?"

"I'm so sorry but there isn't a lot of time, Mark needs help. He's not doing well right now and you're the only one that can actually do anything about it. Please help."

What the fuck was going on?

"Wait I'm really confused, why are you fockin' talking in third person?" Jack asked, standing up and looking at the clock.

"I apologize that I don't have time right now to explain it, but sadly the psychiatrist isn't helping him and he's getting worse," Mark, or someone who sounded like him, kindly answered. The way he spoke alarmed Jack, sounding urgent in a way that he had never heard him talk before.

"Um, okay, so what do I do?"

He waited anxiously for an answer, completely lost and weary.

"What do you think? God, and we thought you were supposed to be smart too. It's what's supposed to be in the writing isn't it?" Mark snapped, growling. Baffled at the uncharacteristic change, he half mindedly confided that Mark was possibly drunk or something like that in order for him to be that erratic.

"Look man, you should go lay down. I don't know what's going on but I think you're drunk. I hope you are cause go to sleep dude," he finally replied, sucking in a deep breath. It was 6 in the morning here and god only knows what time it was over there but it was sure to be late.

"He's not drunk, it clearly says he's losing control. Haven't you read a book before or are you illiterate too? Jacksepticeye will now get offended by what Arthur says but will-"

Jack pressed the end call button, shaking his head. He wasn't in the mood to deal with Mark being a jackass to him. Although that wasn't like him at all, he was a happy giggly drunk, not an angry one. Aside from that it was rare for him even drink. His phone buzzed once more, contemplating for a split second if he was ready to get insulted again.

"You son of a bitch, you weren't supposed to hang up."

"Dude stop with yelling, what the hell is going on?"

He heard the older man let out an exasperated sigh, probably shaking his head.

"I can't do this, Markus you need to talk to this idiot."

After a minute of deep breathing, the tone of his voice changed toward Jack, being calm and patient.

"Sean, I know this is all very frightening for you but when is the next flight you can get to America?"

Mark never called him that, not even when he was talking about him.

"Probably this afternoon but I don't know. Are you okay?"

"We.. Mark is in fact hurt, but he's going to get some help. Please come as soon as you can, we're counting on you."

The phone hung up on the other end and the green haired lad set his phone down, shaking and rubbing his head. There was no way that was real, he needed to just wake up now. So he closed his eyes and breathed in.-
