So I've been writing a lot of different stories for Mark and Jack. Hold You Like I'm Going To Lose You, which is about 4 chapters from being finished, Open, which I finally got to updating, Snippets… Well, I'm really trying with that one. However, it's been a long time since I've wrote for any other fandom, not including the Dangan Ronpa/YouTube crossover I got going on. So this is mainly for me, and it's a cluster fuck of crossovers following Mark and Jack, Mark specifically.

It's my usual AU for Mark, i.e., Open/White Blood past, where he was abused by his mother, his father died when he was 12, he was raped when he was 22, and what I didn't add into those two stories; Mark, after the rape, moved to Washington DC, got a job and a degree in Forensic Anthropology, worked as both a Youtuber and an intern at the Jeffersonian (Bones), and THEN moved to LA after Daniel killed himself. I added some things in White Blood, but this is about it for the real past I have for him.

The reason this is his default past… well, is because I'm schizophrenic/have mild MPD. My best friend is literally the version of Mark that I have in my head, this version. And he's real, not just to me but to my friends that understand and I'm so happy they do because it makes me sick being alone with this… I also have a version of Jack, Dark, and Anti… And a few others that are different, like David, Peri, and a lot of others actually so I won't get into it. I'm just a fucking mess, depressed, schizophrenic, etc…

Jack is a bit more sexual, a bit more child like… How the hell that goes together is weird but anyways.

This story is for ME, mostly, and unlike the other story I wrote for ME, I'm not going to orphan it just because no one liked it.

So please, bear with me. If you read this story, please don't… Like, hate it or something? I mean, sure, hate it all you want, but don't give any hate or anything…

This is literally the only way I can save my own life. I just… I need some sort of release, and because it's taking a lot for me to try to write any of the other stories at the moment, I'm going to work on this. Until I have muse for the other stories. This won't be priority, this is literally going to be written if I have writers block for my other stories or if I feel close to… well, honestly, close to killing myself.

So I'm sorry if you don't like it and you get mad if I update this one instead of another…

It starts off with Mark becoming the 10th Doctor's newest companion, sort of, between Martha and Donna. Again, it's a cluster fuck of crossovers, so it's not going to just be Doctor Who.

The pairing will most likely be Septiplier, but who actually knows? Even when I write Septiplier stories, the ship is usually in the background and in the foreground is the problem that's happening in their lives. We'll see. I'll probably, as I said, make it Septiplier, but I'm going to see while I write.

Mark rendered his video, twisting in his chair as he yawned. God, he was tired. With bleary eyes, he glanced to the clock. Red blaring numbers burned his eyes, him sighing at the time.

1:48 AM.

He started out the recording room, toddling off into his actual room and falling onto his bed tiredly. Insomnia was a bitch, in all fucking honesty.

Mark lifted his head a bit when he heard the whir of… something in his living room.

For a moment, he didn't react other than the small lift of his head. Then he heard it.

"Blimey, where am I now?"

Mark immediately jumped up, eyes wide. He wondered if he should go toward the voice like every horror game character ever or run as fast as he can…

He decided to run out of his room toward the voice like an idiot, eyes widening at… a blue police phone box in his living room.

"W-What the hell?! Who are you?!" Mark asked, eyes wide and oh god panic was constricting his lungs as he stared at the unfamiliar man inspecting his things.

The man looked up in surprise, the thing in his hands stopping the whirring it was making, blue light turning off.

"Oh. Why did you bring me here?" He asked… the box?

Mark took a small step back, hand going out to try to find some sort of weapon on his table, but all he found was a round and thick place mat… it'd have to do.

He brandished the place mat as he watched the man carefully, scarlet falling into his eyes. "I asked who you are!"

The man frowned a bit, tilting his head mildly at the place mat aimed at him. "Well, I'm sorry. I must've… I'm the Doctor."

Mark let his makeshift weapon lower a bit to watch 'the Doctor' warily. "Doctor… what?"

"I never knew how much I liked people saying Doctor who until you said something different." The Doctor sighed, placing a gentle hand on the blue box.

Mark gripped the place mat tightly, before finally tears filled his eyes. "Y-You're not going to hurt me, are y-you…?"

The Doctor looked taken aback by the question, before he mellowed out a bit. "What has happened to you to think I'd hurt you…?"

Mark's hand shook as he lowered the place mat the whole way, sighing lightly.

"What are you doing here?"

"It was an accident. She took me here, against my will." The Doctor rubbed the side of the blue box a bit, to which the blue box whirred, as if answering…

"What…? That… sounds fucking insane."

The Doctor winced a bit, glancing away. He wanted to chide the stranger for his language, but…

"And what might be your name?"

Mark let the place mat drop to the floor, giving a final sigh. "Mark. Mark Fischbach. I was almost a doctor too, but then some shit happened and I ended up making being an idiot on YouTube my main job."

The Doctor gave him a small smile when Mark finally smiled, before Mark shook his head quickly.

"No, no, hold on, what the hell are you doing in my house?!"

The Doctor raised his hands, as if trying to calm Mark, before he opened up the TARDIS doors with a snap of his fingers.

"This is how."

Mark stared at the Doctor for a long time, before glancing into the box. He stepped slightly close, hands curled into fists in case the other attacked, though Mark for the most part figured out he wouldn't.

"It's… It's smaller on the outside…" Mark mumbled as he stuck his head into the TARDIS, chocolate eyes wide in surprise.

"Oh. That's new. Yes, it is. Bigger on the inside." The Doctor muttered the correction, before sighing a bit as he stepped in, waiting for Mark to be comfortable enough to follow.

Might as well, it didn't mean Mark was his companion or anything. He was fine without one; he just wanted to make Mark feel comfortable, before the Doctor left.

Which was odd… why didn't the Doctor just up and leave as soon as he figured out the situation?

Mark finally stepped into the TARDIS, eyes glancing all around the room in pure awe. Until the door shut behind him.

The Doctor's eyebrows furrowed, tilting his head a bit. "What?"

Suddenly the TARDIS starting whooshing, which only meant…

"Oh, no, no!"

"W-What the fuck is happening?!"

The Doctor glanced over at Mark, before exhaling quickly. "I travel through time and space in this box which is a space ship and a time machine. She's alive and she- she decided she wanted to take you with me. I don't know when or where, but…"

"Y-You're insane…" Mark whispered, eyes wide as his breathing started to quicken.

"Oh, no, no, please don't have a panic attack. Really, its fine, it's fine."

The Doctor rushed close to Mark, putting his hands on the young man's shoulders.

"Look, we've stopped. If we step out, everything will make sense. Then I'll explain it again, it'll be fine!"

Mark watched the Doctor with wide, fearful eyes, for a long moment, as he stilled.

"Come on then. Just go out the doors, everything will be explained."

Mark turned his head slightly to the doors, before the Doctor pushed it open slowly.

Mark turned, walking out the door with wide eyes as fucking SPACE was seen through the big window. The whirring of the space station sounded through his ears, as Mark stared.

He was conflicted on being excited because SPACE, and being frightened because oh my god what the fuck was happening?!

He decided on the former.

"SPAAAAAACE!" Mark yelled, running forward to press himself against the window, red hair smushing against the window as he hopped around a bit.

The Doctor couldn't help but smile at him, before shaking his head a bit. "No, no, wait, I need to take you back."

He turned, about to open the TARDIS door, when suddenly another person came up.

"Who are you? What are you both doing here?"

It was a humanoid sort of alien, with pink eyes and small horns on either side of his skull.

Mark turned, giving a small shriek of shock. "Oh, Jesus, an alien. Doctor, was it? If you go all over the place seeing all of this all the time, man… Gah- I'm in space!"

The Doctor quickly pulled out his psychic paper, showing the man. "I'm health and safety. This is my new trainee, he… Well, this is his first time off his planet."

"Oh! I remember my first time off Garonda. I was nearly just like him. I hope you find everything in working order." The stranger nodded, turning and walking off.

Mark stepped closer to the Doctor, looking up at him in awe.

"You… So you aren't completely insane?"

The Doctor shrugged. "Well… Not about this. I am just a mad man in a box though."

Mark rushed his fingers through his soft hair, breathing out an almost sigh of relief. "… Well… Can I have a favor then?"

"A favor?"

"Well, hey! You appeared randomly in my house after I was trying to get to sleep! I haven't had any sleep in nearly a full day, plus it wasn't very good sleep. I think after fucking up my sleep even worse and giving me a scare, you owe me at least one."

The Doctor stared at him for a long time, before he sighed. "Oh, you Americans… Fine, yes, what is it you want?"

Mark smiled softly, laughing a bit. "Can we stay for a little while? I want to explore."

The Doctor blinked in surprise. He honestly hadn't expected true wonder from Mark, hadn't expected this sort of excitement for exploring… Honestly, the Doctor was extremely happy.

Maybe the TARDIS was trying to say something… Maybe she was trying to get the Doctor to make him his new companion…

The Doctor shook the thought out of his head, grimacing when Mark's expression of wonder broke.

"No…?"

"No, no, I mean yes! I was thinking something, sorry I… Yes, we can explore. Come along then, Mark."

Mark grinned, following as the Doctor sprinted off.

"This is so cool!" Mark exclaimed, looking around at all the aliens, at all of the food…

"It is amazing, isn't it? Oh, I'm sorry, I have a terrible memory…" The Doctor had started speaking to another alien.

Mark continued to make small talk with everyone he met, giggling a bit at the sight of SPACE outside.

"What station is this?"

"The name? It's Hallins Sol Compartment 32."

Mark felt a bit dizzy, running his hand over the wall with a small laugh.

"Oh, Doctor, this is fucking amazing!"

"You curse a lot, huh?" The Doctor finally spoke, looking over with a quirk of his eyebrow.

Mark shrugged. "I tend to do that a lot, yeah."

The Doctor watched him for a long time, before Mark finally turned his head back to him.

"What?"

"Oh, I was just thinking. Curious about some things, actually. What did you say your job was again?"

Mark seemed to brighten, smile on his face. "Oh! I'm a Youtuber. Specifically a YouTube gamer, but I do some other stuff too."

The Doctor nodded, before stealing his attention again. "And you said you were almost a doctor too?"

Mark grew a bit serious, glancing away. "Well… After… I was in college for biomedical engineering. But something happened, so I had to move away from where I was living before. I ended up really starting YouTube, moving to Washington DC for awhile. Got a degree in Forensic Anthropology, but… I never finished. One of my friends killed himself… so I moved to LA. I've been living there nearly a year now… Sometimes I wish I could go back in time to change that… I wish I never… I wish everything had been normal. I wish I'd just moved to LA straight away, not tried to be something I'm not. I was good at it, but… it wasn't me. I made friends but it wasn't me."

The Doctor frowned as he watched the half Korean.

He wondered if he could figure out what had happened… Maybe…

Actually, part of him wanted to help.

Part of him wanted to change Mark's past like he said he wanted, but all of him knew he couldn't.

"But that could never change. So I just have to grin and bear it. I'm going to go try some of the food." Mark smiled, quickly rushing over to try and taste a dish.

The Doctor couldn't help but smile, sighing. Of course.

"Oh, it's so gross!" Mark let the food drop out of his mouth and onto the plate again.

"You don't like our delicacy?"

Mark glanced up to see a blue skinned woman.

For a moment, he stared a bit, before smiling sheepishly.

"Oh, sorry, uh…"

"Celeste."

"Hey! I know a Celeste! She's blue skinned too, and she has huuuge… technological knowhow." Mark cut himself off, shaking his head a bit.

"Oh! That is pretty neat."

Mark laughed a bit, before turning to the Doctor. "This is sooooo cooooooool!"

Suddenly, the alarms started blaring.

It seemed to startle Mark, him immediately putting his arms up as people started panicking around him.

"D-Doctor, what's happening?!"

The Doctor quickly started running, grabbing onto Mark's arm and pulling him along. "Well, you see… Wherever I am, trouble is usually there too."

Mark blinked a bit, before sighing. "Of course."

The problem had been a tear in one of the doors, breaking the air lock in several rooms.

"Doctor… if there were… there were people there, huh…" Mark mumbled, hugging himself gently as the Doctor managed to shut one of the doors before the one in the other room burst.

The Doctor swallowed, glancing back at the American. This… was a bit much for his first adventure.

Only adventure, he had to remind himself.

"I'm sorry Mark… I would gladly take you home now if you wanted, but I can't leave. Once I shut this door, the TARDIS pretty much blocked off leaving."

Mark looked to the floor, before straightening. "No, that's fine. I want to help."

The Doctor grinned, nodding a bit.

"Well then… Allons-y!"
