Pairing: Damian Wayne x Reader
divider by: @cafekitsune & @thecutestgrotto word count: 1.6k synopsis: To Damian Wayne, this is just marriage. To his brothers this is a one way ticket to Arkham. a/n: Damian's version to 'Til Death Do Us Apart is here! I think he's so far my favourite out of the series. I was watching The Addam's Family while writing this and he's so Gomez coded!
Damian Wayne had been stabbed twice, poisoned six times, almost lost a finger, and very nearly attacked by a Caspian cobra that had mysteriously appeared in his closetâthough, in the end, he simply adopted the serpent and named it Caspian.
He wasnât upset about any of it.
In fact, he was starting to consider it foreplay.
Most people wouldnât interpret a tripwire on the staircase or a gas-emitting bookshelf as romantic gestures. But Damian was not most people.
You were, after all, an assassinâone of the most lethal in the world, a Black Widow. And also, his wife. Which meant that affection came with a few⊠complications.
Like needing to sniff his tea before every sip.
That morning, he sat in the garden beneath the soft canopy of climbing vines, a leather-bound Persian manuscript resting in one hand, a delicate china teacup in the other. You floated into view like a vision, carrying a fresh tray of biscuits, teapot and a suspiciously serene smile that usually meant something was about to happen.
You refilled his cup with practiced grace, the scent of jasmine rising between you. He brought it to his lips, took one measured sip, then paused. His nostrils flared slightly. He sniffed again.
âBelladonna?â he asked, not looking up from the page.
You set the tray down, gently brushing crumbs off your fingers. âOnly a trace.â
He hummed thoughtfully. âToo floral. It throws off the jasmine.â Another sip. âNext time, try aconite. It blends better.â
You leaned down, pressing a kiss to his hair. âNoted.â
Your attempts came and went like the seasonsâsome subtle, some so absurdly theatrical it was almost comical. Once, youâd rigged the libraryâs fireplace to release a sleeping gas if the wrong book was pulled from the shelf. You knew Damian would figure it out. And he didâof course he didâthough he was a little smug about it.
He crouched by the hearth with a small, curved blade in hand, dismantling the delicate mechanism with an ease that irritated and impressed you in equal measure.
âI almost admire the mechanism,â he said dryly, flicking a piece loose and catching it mid-air. âYouâre improving. The trigger delay was clever.â He glanced over his shoulder, eyes glinting. âYouâll have to try harder next time.â
And you had.
The following week, youâd set a spring-loaded dart trap just outside the hallway near the greenhouseâtimed perfectly to his morning routine, right as he turned the corner, casually eating an apple.
The dart whistled through the air.
Damian shifted to the left without so much as blinking. The dart missed him entirelyâonly to pierce straight through the apple and embed it into the wall with a soft thunk.
He stared at it for a moment. Then calmly walked over, plucked the dart free, and retrieved the apple.
âYouâre getting lazy,â he remarked, holding the dart up to the light, examining its make. âThis oneâs off-balance. It veered left.â
âMaybe I just wanted to nick you,â you said breezily as you strolled past, lips twitching into a grin. âYou did mention needing to work on your reflexes.â
He chuckled under his breath, biting into what remained of his apple.
âHow considerate, beloved,â he muttered.
But then came that Sunday afternoon.
Damianâs brothers had come overâagainst his better judgmentâfor what they claimed would be a âsimple brotherly brunch.âÂ
Within minutes, he regretted opening the door.
His home was louder than usual, filled with overlapping voices, the clatter of silverware, and the relentless stream of bickering that passed for affection in the Wayne family. The pancakes were drowned in ungodly amounts of syrup. Someone had opened a bottle of orange juice with their teeth.Â
And worst of all? Someoneâhe still didnât know whoâhad touched his katana display. There were smudges. Smudges. Left on the usually pristine, sparkling glass. He said nothing. But he made a mental note to run a full scan later and find out exactly which one of those imbeciles had committed the crime.
He had just excused himself to fetch something from the west wing and only made it half way across the dining room when it happened.
A soft click.
He froze mid-step. Looked down.
A pressure plate.
From his seat, Jason glanced up, a fork halfway to his mouth. âWhat was that?â
The ceiling above them shifted with an ominous creak.
And thenâwhoosh.
A pendulum blade, polished to a mirror shine, dropped from the rafters and arced through the air like something straight out of the Addamâs family. It missed Damian by less than an inch as he pivoted smoothly to the side, ducking in one seamless motion. The blade swung past with a rush of air, that ruffled his hair.
The others froze mid-bite, forks suspended in the air, expressions shifting from confusion to outright horror.
Before anyone could react, another panel hissed openâthis time along the wall. A rapid clickâshhhk echoed through the room as sleek, retractable knives launched from hidden compartments, hurling straight toward Damian.
He moved like waterâgraceful and effortlessâspinning out of the way, one hand casually snatching a blade mid-air. While another knife sliced cleanly through the fabric of his sleeve, but didnât touch skin.
He exhaled, long and put-upon.Â
âAgain with the ceiling blades,â he muttered.
The others, however, were not so composed.
âWHAT THE FUCK WAS THAT?!â Jason barked, nearly flipping his plate as he bolted upright.
Dick stood, wide-eyed, gaze darting to the now-settling blades embedded in the wall. âAre you okay?! What the hell just happened?!â
Tim was already pulling out a compact scanner from his pocket, frantically scanning the room. âIs the house booby-trapped?! Did someone breach the security grid?! Is there an intruder?â
Damian remained exactly where he was, unbothered, as he studied the captured blade that was held delicately between his fingers.
âNo intruder,â he said annoyed at the clear overreactions. âThis was my wifeâs work.â
All three stared at him in horror.
Tim blinked. âYour wife just tried to impale you,â he said slowly, carefully, as if explaining a basic law of physics to someone who shouldâve known better.
Damian hummed to himself, turning the blade between his fingers, letting the light catch the polished steel. âSheâs improving,â he remarked. âThese ones actually had decent balance.â
Jason just stared. âWhy the fuck are you so calm?â he snapped. âSHE JUST TRIED TO KILL YOU.â
Damian let out a slow sigh, clearly irritated by the dramatics. âShe didnât try to kill me,â he said, as if the distinction was obvious. âIf she wanted me dead, I would be.â
âDamian,â Dick said, cautiously, as if speaking to a feral animal.
âSheâs just being affectionate.â
Tim blinked. âThatâs not affection, thatâsââ
âItâs her love language,â Damian interrupted, stepping around the still-swinging blade without a flinch. âSheâs very dedicated to making sure I'm aware of her love.â
Dick looked like he was about to pass out. âYouâre telling me this happens regularly?â
Damian shrugged. âYouâre just upset no oneâs ever loved you that much.â
Moments later, you strolled in, utterly unbothered. Silk robe tied neatly at the waist, not a single hair out of place. In one hand, a steaming cup of coffee. On your lips, a soft, pleasant smile that nearly made it hard to believe you were the architect of the carnage around the room.
âGood morning,â you greeted cheerfully, leaning in to press a kiss to Damianâs cheek before casually glancing at the embedded blades. âDid the new blade wall trigger too soon?â
Damian nodded as he tucked you to his side. âOff by two seconds. Adjust the fuse delay.â
You let out a quiet sigh. âNoted.âÂ
Your gaze shifted to the blade still turning slowly from the ceiling. You tilted your head. âIs that one still rotating? I meant to fix the alignmentâitâs drifting too far left.â
âI told you to aim for a clean ninety-degree arc,â Damian added, glancing down at you. âYouâre losing power on the backswing.â
You made a soft, thoughtful noise. âI was worried about overcompensating.â
âNext time,â he said, without missing a beat, âuse a counterweight.â
Jason looked at Dick. Dick looked at Tim. Tim looked like he was ready to drag you both to Arkham and check you two in under a shared room. The three of them turned back in unison, staring at the two of you standing thereâutterly calm and composed, as if you were discussing home dĂ©cor and not lethal traps embedded into the manorâs infrastructure.
Jason blinked. âYouâre two are joking, right?â
âOf course not,â Damian replied coolly, taking the coffee cup from your hand with ease and pressing a kiss to your cheek. âWeâre a team. I only wish the best for my beloved.â
âI donât think the feeling is mutual,â Tim muttered under his breath.
Damian rolled his eyes and took a slow sip of the coffee. He paused, considered the taste, then added matter-of-factly, âThis is poisoned, isnât it?â
You tilted your head, smiling sweetly. âJust a touch of cyanide.â
He took another sip, unfazed. âThe coffee was already bitter. This just makes it more obvious. Try strychnine next timeâitâs cleaner.â
You giggled and kissed his cheek again. âYouâre so picky, darling.â
Dick stared at the two of you, eyes wide, colour slowly draining from his face. âIâI think heâs going to die.â
âNo,â Damian said simply, sliding an arm around your waist as the two of you turned and began walking awayâutterly unfazed by the blades, the scorched wall, or the stunned expressions behind you. âWe made vows, Grayson. I promised to love her, cherish herâand survive her.â He glanced over his shoulder. âThis is just the life of marriage.â
And for Damian Wayne, it was everything he could have ever asked for.
