"What is it?" you asked, moving to his side by the console.
The radar display showed a single, insistent red blip against the sweeping green arc.
"It's a goddamn ghost story," Gunther muttered around his cigar.
Or:
A crossover between In Space With Markiplier’s warp-core chaos and Mouthwashing’s horrors. The Invincible II finds a long-lost ship adrift—but some missing things should stay forgotten. -

Summary
"Mark."
He lifted the hand full of peanuts.
"Mark."
"Give me a reason."
"Mark! No, no, Mark!"The Captain tried pushing away, only succeeding in tangling themself in the blanket they hadn't realized curled around their body. "Mark! They're gonna get everywhere- Mark!"
"Doesn't seem like my problem."
"Mark!"
Mark's hand went into motion.

Time And Time Again I Went Away, But Then Would Come The Time When I Would Need You by Far_Writer6952

Summary
Nightmares woke you again for the fourth night in a row. Usually, you were able to calm yourself down, curl up in bed and repeat the same mantra to yourself as you tap your fingertips together and count.
But tonight was different. You saw Mark die, you saw him be torn apart by a black hole, shot by some Lady, sent out of the bay window and hurtled in the vacuum of space.
You saw multiples of him, all different and chaotic and mind boggling, claiming to know you and you’d think you’d know them. For a moment, you’d swear you remembered this life, but no.
No, they weren’t him. They weren’t your Mark. They looked like him, but they weren’t.

Summary
You blink, your breath leaving you in a shudder as you lift your head to look up at the familiar and concerned face.
Another nightmare, another uninterrupted sleep and the mindless panic that would have sent you right off the bed if it weren’t for him.
Him, who’s now gently wiping at the stray tears and asking if you’re okay.

Summary
“I don’t think I can live without you, Captain."
Of course he knew that the Captain loved him to some degree. And maybe she didn't outright say it, but she doesn't need to for him to know that she does. And he hoped she knew he loved her, too.
Because even when he was angry at her, even when he still believed it was her fault for him getting stuck in his own hell, his first instinct was to grab the Captains hand and beg her to hold on. He knew she would, even after everything he's done. His hand moves down to her wrist, pulling her hand up and kissing the dark scar on her palm.
He did that. And even if she told him again and again how much she forgave him, he didn't forgive himself. He doesn't know if he ever could.
"I can't live without you, either, Mark."

Summary
“Hey, what month is it?”
“Excuse me?”
“The month. You know, a unit of measurement to tell us how far Earth has made it around the Sun that we're somehow still using even though we're so far away-”
“I know what a month is, asshat.” Celci cuts herself off with a huff. Mark clearly wasn't paying attention so she was just wasting oxygen explaining a problem in cryo. “It's February. The 13th.”
“Oh, thanks-” His eyes widened as he paled, realizing what that meant.
Tomorrow was the 14th. Of February.
Valentines Day. And he had nothing planned.
~♡~
Happy Valentines Day from me to you

Summary
With him, they could just be themselves. Just be another person, a partner, a friend, a lover. An old fashioned phrase, but fitting. Sentiment and soft and embodying everything they're looking for in life.
And they found that in Mark. They found that during hours upon days of loops and wormholes and death and destruction and pain and anguish and oddities and guilt and-
And a deep, aching pain in their chest as they realized that they couldn't live without him.

Summary
They wished he'd realize he was a good person still. He was forgiven, he wasn't bad or evil in their eyes.
He was theirs and they were his. That wouldn't change. The experience with the warp core and the crystal only solidified their relationship and made them realize their feelings for him.

Summary
It hasn't been long since your first kiss, yet there's something to the relationship between you now that leaves you almost nervous, hesitant; there is something more and you know it, you want it, you're right at the edge and ready to leap for it, but something forces you to falter, to pause.
This is the next step towards something more and you know it.

Summary
This wasn’t the first time he was waking up from cryo sleep. He’d awoken here before, in various stages of panic (more times than he actually remembered).
After last awakening, Mark hadn’t anticipated ever waking up here again, confined to this cold tomb. Back to this ugly part of him he had been so sure he left behind in the chilly fingers of space. He thought he'd left for good, but it seems that Mark couldn’t escape his past after all. For as much as he wanted to take all he’d done and completely forget about it, he’d never be able to escape it. One more time. One more time to not completely mess things up for his… for the Captain.
Mark was going to start over. He was going to make all of this up to his Captain. Even if it was the last thing he did.
The Captain wasn't oblivious. And they weren't turning a blind eye to their Head Engineer.
