Final hour Ghostlights request! Soulmate AU where when your soul mate dies your soul mark expands. Duke was really heartbroken at first but now his soul mark makes it really difficult to keep his secret identity hidden because he is covered in a map of the cosmos. He has to use his shadow powers almost constantly to keep all the stars hidden! And and maybe they light up like actual stars when he uses his light powers.

He meets Danny at orientation or something at GU and they brush against each other and he just lights up like a supernova, all his stars literally blazing and he's just like "YOU!" Both excited and also OH MY GOD YOU ASSHOLE.

....I rambled a bit here I'm so sorry.

The thing about soulmates is that you don’t really know who they are until they die. And even then, most people never know who their soulmate was, only that they outlived them.

Duke became one of those people when he was thirteen.

He didn’t even notice until he went to change and saw the watercolor swirl of nebula spill out from over his heart.

One moment, he was tired and angry, ready to sneak out of his latest foster home to search for his parents and do all the things adults have failed to do. The next, he’s collapsed on his knees, shaking, unable to breathe as he tries to rip his soulmark off of his skin. He couldn’t think past the shock and horror of realizing that his soulmate is dead and Duke didn’t even know until that moment.

They’ll never get to meet.

Duke had never felt so alone before.

He spent the next few days in shock, his mind a mess of static, unable to focus. He hid away in his room, buried under the covers, and his foster parents were understanding when he whispered my soulmate’s dead. They called him out of school and brought him food and water throughout the day, gentle encouraging him to eat something every few hours.

But disaster waits for no one, and Batman was gone, so Duke pulled himself out of his misery and hit the streets again.

So his soulmate’s dead. So his parents are gone. So Gotham’s falling apart.

No one’s doing anything about it, so it’s up to Duke to start fixing things. It’s not like he had much to lose.

Soulmates become a bit of a taboo topic to him, after that. He speaks of them to no one, avoids all conversation about them, refuses to stay when people talk about soulmarks. He tries not to look at his soulmark at all.

And then he takes a hit to the chest and patches himself up with shaking hands. For the first time in months he looks at his soulmark again and…

Did it… grow?

Duke prods it gently, letting out a hiss when his bruised ribs protest at the movement. He remembers the mark being right over his heart.

But looking at it now, it branches out, swirls of galaxy and constellations reaching out along his ribcage.

Panicked, Duke grabs for his computer and looks up soulmark growth and webmd soulmark abnormalities.

Neither give him any answers, though WebMD helpfully suggests skin cancer.

“I’m gonna ignore this,” Duke decides, and pulls on a shirt and goes to sleep. The less he thinks about his dead soulmate, the better.

Time passes and Duke goes from being a Robin to being the Signal, a legitimate vigilante working with Batman. It’s nice to see Gotham start to settle, things falling into place. For once, nothing is awful; Duke’s found his parents and doctors are looking for a cure for long-term exposure to Joker Gas, Batman’s taking care of Gotham with a number of other Bats, Duke is getting used to his powers and slowly making a good name for himself out on the streets.

He keeps his focus on protecting people and getting stronger, helping solve cases with the other Bats. No one mentions soulmates, so he keeps his ever expanding soulmark a secret.

The only problem is that it keeps growing and Duke is concerned that it’ll move to a place he can’t easily hide under his clothes.

And he does need to hide them. The more his soulmark has grown, the more obvious it is, especially when he uses his powers and the stars on his skin light up like the Fourth of July. He knows it’s abnormal, but it’s also his soulmark and he doesn’t want anyone, least of all Bruce, poking around trying to study it.

The grief still lingers when he looks at it, but Duke has long since grown used to it. If anything, these days he’s quietly annoyed by how far the galaxies on his skin spread out, forcing him to take tank tops and shorts out of his wardrobe.

There’s also the tentative hope that maybe his soulmate is immortal and keeps coming back to life after they die. And they must also have terrible luck, because they just keep on dying.

Case in point: his soulmark flares and spills out onto his shoulder and wraps around his bicep. It’s not the first time he’s seen it move, but it still startles him.

“Are you serious,” Duke mutters to himself, pulling at his sleeve to adjust it and hopefully hide his soulmark. The starts are bright against his skin, and while sometimes he likes to trace them with his finger, now is not one of those times.

As pretty as it is, his soulmark is also very obvious and will cause people to realize his identity if they ever catch a glimpse of it while he’s out as Signal.

He sighs. There’s no choice but to live out the rest of his life in hoodies and sweatshirts.

As if to spite him, his soulmark grows once more.

Did his soulmate just die twice in the span of five minutes? That’s concerning.

He wishes he could meet them just so he can shake some sense into them. Maybe tell them to stop dying since it’s stressing him out so much. Maybe stick by their side to make sure they never have to die again. He’s honestly not sure what he’d do if he ever meets his soulmate, but he has to do something. This has gotten out of hand.

At least seeing his soulmark grow doesn’t hurt as much as it did a few years ago.

Lazily, he pulls at the light around him to hide the new portions of the soulmark on his arm from sight. It takes some focus, but he can hold it up long enough for him to grab a snack from the kitchen and retreat up to his room without being questioned by anyone. He could probably even keep this shirt on for the college orientation he needs to attend later in the day if the light works well enough to keep his secrets hidden.

He’s expecting Alfred in the kitchen when he arrives, but is greeted by Dick clapping a hand on his shoulder, right where his soulmark has claimed space. Duke falters and works to keep the light from fracturing as he returns Dick’s grin.

“Hey man,” he says, “What are you doing here? I thought you were out until Friday.”

“And miss a chance to hang out with you? No way. Besides, I wanted to give you a ride to your orientation.”

“You don’t have to,” Duke starts, only for Dick to cut him off.

“I’m going to,” he says, as if it’s a threat. “It’s been too long since we get to spend time together without a mask on. Are you really going to deprive me of this?”

Duke shakes off Dick’s hand from his shoulder, walking towards the pantry to find a small snack. “I guess not. It’s going to be pretty boring for you, though. I’m just going to listen to people talk about what college is like for a few hours.”

“We could always just walk around campus afterwards. I haven’t seen it since it was rebuilt after the last time Freeze attacked it.”

“Sure, that sounds fun. Thanks for offering to drive me.” Duke pulls out a box of Poptarts hidden behind stacks of pasta boxes and pulls out a pack for himself. He opens it and isn’t at all surprised when Dick steals one right out of his hands.

“Meet me out front in an hour then.”

And with that, Dick leaves, his stolen Poptart in hand, and Duke is left to shake his head and shove the Poptart box back into its hiding place. He heads off to eat his own snack, making sure no one is in the hallway as he lets go of his hold on the light. Already he can feel a migraine building with the immense focus he had to use to make sure nothing looked out of place.

At least Dick didn’t notice anything was off. If he can fool Dick, he can fool anyone.

Still, just to be safe, Duke changes into something with longer sleeves before he leaves and hops into the car with Dick.

The drive goes quickly to the tunes of ABBA, both of them singing along as they head for the GCU campus. Parking is a bit tricky, but they manage to find a spot a street away and walk towards the student union, where tables are laid out for incoming freshmen to sign in and grab a folder filled with papers meant to help them.

He waves to Dick and heads in once he gets his folder, and grabs a seat in the auditorium that’s close to a fire exit.

It takes another twenty minutes for the presentations to start. The lights dim and Duke panics for a brief moment before drawing the shadows over himself lightly to hide the soft glow of the star etched onto his skin.

They start with introductions, bringing in advisors, professors, and student ambassadors. Most of it is basic information that Duke already knows, so he zones out and plays with some shadows at his feet, where no one can see the way he twists shadows together like some dark magic form of finger knitting.

For the next hour, Duke halfheartedly listens to people talk about preparing for classes and keeping on top of schoolwork and learning how to ask for help. He’s saved enough college students that he knows the gist of things, and the orientation really doesn’t give him anything helpful.

He probably could have skipped, but he wanted a normal college experience.

He should have known that normal means boring as hell.

As soon as the presentation ends, an advisor encourages everyone to follow the schedule tucked into their folder to give them a half day modeled after a typical student’s schedule. Of course, all the classes are nonsense just to fill up their time, made to help freshmen coming into the college by covering topics such as how to write an email and an introduction to majors and minors.

Duke already declared himself as a Human Services major, his first step into becoming a social worker like his mom was.

Also he totally knows how to write an email, what are these advisors on about? Do they really think people his age can’t write emails?

Yeah, he’s ditching. The main presentation is really the only part that matters in the orientation. He’s not walking out on anything he needs.

Duke files out after the rest of the crowd, carefully letting the shadows slip off of him once he’s outside again. Instead of finding the first ‘class’ he’s supposed to go to in the Modern Languages building, he wanders off to find a quiet place he can sit down and wait until Dick finds him.

Tucked away towards the back half of the campus is a small nook full of trees, bushes, and benches. Judging by the amount of cigarette butts left in the single trash can there, it’s a popular smoking spot.

No one’s there, so the air is clean and free of smoke, so Duke heads in, hoping to sit down.

Someone else apparently has the same idea. He hops down from one of the concrete planters that’s keeping a bush contained and nearly falls on Duke.

They both shout in surprise, then Duke is moving without thinking, reaching out to steady the startled looking guy who accidentally jumped down in front of him.

Duke only has time to take note of how blue his eyes are before his hands wrap around the guy’s wrist and Duke feels his soulmark flare with warmth.

In the shade of the trees, the glow of each star on his skin is obvious. It’s visible even through the fabric of his shirt. His soulmark, at this point in his life, stretches across his chest, his ribs, his back, and now his shoulders and upper arms. All the stars in that watercolor galaxy are shining brightly as if the night sky has been draped across his body.

Soulmarks only react like that for one reason.

“You!” Duke shouts at his soulmate, both elated to see that he’s alive and annoyed that he made Duke’s soulmark so large. “Stop dying! Do you have any idea how much stress you’ve caused me?!”

“Oh my god,” the guy says faintly, eyes fixed on Duke’s chest where his soulmark originally rested, shining brighter and bigger than any other star, as if he’s tucked a sun into his heart. “Oh my god,” he says again, with more feeling.

“I’m so happy you’re alive, but please stop dying. It’s bad for my health.”

“I think I need to sit down?”

He does look very pale and faint. Duke tightens his grip on his soulmate’s arms and guides him to a bench, gently sitting him down.

“You’re not about to die, right?” Duke asks. “I don’t think my heart could take it if meeting me killed you somehow.”

“No, no,” his soulmate manages to say, “I’m not going to die. Um. Wow. I didn’t know my soulmark would do that? Sorry.”

“Well, it’s not like you had any way of knowing. It’s all good, man. Just please stop dying.”

His soulmate winces. “Yeah, that’s not gonna be possible. Sorry. Again.”

What does that mean, though? What does it all mean?

“Can I maybe get an explanation as to why you have to die again.”

“Mmmmm no. We just met and it’s kinda personal so. No.”

“Dude.”

Duke’s soulmate shrugs helplessly. “It really is personal! I know your my soulmate and all, so I’ll probably tell you one day, but right now I don’t even know your name.”

Oh shit. He’s right. Introductions completely slipped his mind, too busy reeling over the fact that his soulmate is here and alive. Which, honestly, would be enough to throw anyone off balance.

“Shoot,” Duke says. “Sorry. You just really caught me off guard. Hi, I’m Duke, I promise I’m more put together than that.”

“Hi Duke, I’m Danny, and I’ve apparently been traumatizing you for the past few years by making you think I keep dying.”

“Well. At least we’re thrown head first into the crazy. Best way to know if we’re be a good match.”

“You sure you can handle this? You seemed pretty frazzled a second ago.”

Duke flusters and lightly whacks Danny’s shoulder. “That’s normal! Anyone would do the same when meeting their soulmate for the first time!”

“Fair enough,” Danny laughs. “This is a totally weird request and you can absolutely say no, but… can I see?” He presses a hand against one of the glowing stars beneath this collar bone, looking up at Duke with wide, hopeful blue eyes, and Duke finds it so cute that he’s willing to do anything Danny wants.

“Here,” he says as an answer, pulling the collar of his shirt down a bit to reveal the nebula spilling onto his shoulder.

“Oh,” Danny breathes, tracing a light finger against it. “It’s beautiful.”

“I’m guessing you like space?”

“Love it. I wanted to be an astronaut, but uh…. It’s never going to happen. Health problems, you know?”

“Well, I know it’s not the same, but I hope the stars you put on my body will be a good enough replacement.”

Danny cheeks turn red and he turns away, flustered. “Don’t smooth talk me right now, I’m not ready for it,” he mutters, bringing up a hand to try to hide his expression.

“Sorry, sorry,” Duke laughs, “I’ll try to keep the flirting down to a minimum. It’s just really great to finally meet you. And I’ve been wondering, what’s your soulmark look like?”

“Oh, well…” Danny fiddles with the long sleeve of his shirt. “I had a pretty bad accident years ago that kinda affected how my soulmark looks. So if it looks weird, that’s why, okay?” He takes a deep breath, then pushes up his sleeve, holding his wrist out to Duke.

The first thing Duke notices is the soft yellow glow, Signal yellow to be precise, running down his arm as if sunlight fills his veins. Then he sees Danny’s soulmark, a sun with rays that wrap around his wrist. And running through his soulmark are Lichtenberg scars, glowing yellow as if stealing the color from his soulmark.

“Guess we both got super obvious soulmarks, huh? At least we kinda match, that way.”

“That’s one way to look at it,” Danny agrees.

“Man, what a day.”

Danny looks more relaxed with him now. It’s much better than the startled, tense version of him that first sat down on the bench. Duke hopes he chooses to stay with him; he doesn’t admit this often, willingly, or to other people, but he’s a romantic at heart and has always wanted to live a happy life with his soulmate. It’s still far off in the future, but he hopes Danny feels the same way.

“So, are you ditching the orientation classes to?” Danny asks.

“Yeah, there’s no way I’m going. I mean, a class on how to send emails? They can’t be serious.”

“I know, right?! I saw that and thought I was being pranked. I mean, we’re going into college. We better know how to send an email by now.”

“Since we’re both free for now, wanna grab lunch with me? It can be our first date, if you want.”

“I’d love to! And you can show me around Gotham a bit. I’m coming here for college, but I haven’t really seen the city yet. It’d be nice to explore it with someone who knows where things are.”

“Are you free for the rest of the day? ‘Cause I wouldn’t mind showing you around, if you want.”

Danny smiles, radiant. “I am. I’m in your hands for the rest of the day.”

“Cool,” Duke says, trying not to think too much on that wording. It’s very suggestive, very flirtatious, and he’s looking forward to getting to know Danny more so he can start properly flirting. “Lemme just let my brother know to not wait up for me.”

He pulls out his phone and sends Dick a text that just reads: met my soulmate. going on a date now. i’ll see u back at the manor!

Then he puts his phone on silent and tucks it back into his pocket. He’ll tell Dick all about this later; for now, all his attention is on Danny.

Soulmates get priority, even stressful ones that give him the largest soulmark he’s ever seen.

And right now, he’s on a mission to find the best lunch spot to take his soulmate to for their first date. Everything else can come later; for now, he’s going to enjoy the time he gets to spend with Danny.

He hopes they’ve got a future together as bright as the stars in his soulmark.

Despite it all, Duke is sure they’re going to be alright.
