UNEXPECTED GUESTS I

divider by: @cafekitsune & @thecutestgrotto & @omi-resources word count: 835 synopsis: Jason’s secret relationship is discovered by Damian—who keeps showing up uninvited. Jason’s patience is tested, popcorn is made, but at least Damian brought cinnamon rolls. a/n: this one went off the rails slightly and the rest of the upcoming parts are equally as unhinged (at least compared to what I usually write).
Compared to your apartment, Jason’s place was practically Fort Knox. You and he had been dating long enough that you’d practically moved in—and you knew his secret identity. Still, you’d never met his family, something Jason was adamant about keeping that way. You knew of them, of course, but hadn’t expected to meet them anytime soon.
Which was why you definitely weren’t expecting a ten-year-old ninja to break in.
You had just stepped out of the shower when you heard it—the quiet thud. At first, you thought it might’ve been Jason returning from patrol early. But then came the faint creak of the window opening.
Jason never used the window.
Cautiously, you stepped into the living room, still in a robe, hair dripping. And froze.
There, near the kitchen counter, stood a boy. Arms crossed. Hood down. Eyes sharp as blades.
“You’re not his roommate,” he said flatly.
You blinked. Your shoulders slowly relaxed. While you’d never met Damian Wayne personally, you’d seen enough pictures—and heard Jason complain just enough about the “demon child”—to recognize him instantly.
“…And you’re not the pizza guy,” you replied, equally dry, one brow raised. “So I guess we’re both surprised.”
He didn’t smile. Didn’t even blink. Just stared, like he was trying to unearth your darkest secrets with sheer willpower.
“Who are you?” he demanded, stepping forward.
“His girlfriend,” you said, calmly. And waited for the explosion.
There was no point in hiding it. You figured that now that you’d met Damian, it was only a matter of time before the rest of the Bat-family found out. Honestly, you were surprised they hadn’t already—weren’t they supposed to be the world’s greatest detectives?
It didn’t take long.
“I knew it,” the boy hissed. “He’s been acting suspicious for weeks. Staying out longer. Not snapping at everyone. There was even a smile—a smile—on his face during training.”
He circled you slowly, hands behind his back like a miniature detective—or a very judgmental cat. “I assumed he was hiding something. Drugs. Maybe a dog. But you… you’re worse.”
Your lips twitched. “A dog would’ve been worse, to be honest. He’s not exactly home on time for walkies.”
He ignored your joke. “How do I know you’re not a threat? An assassin. A spy. Someone sent to manipulate him.”
You raised your hands in mock surrender. “You think I’m seducing Jason Todd for intel?” You snorted. “Believe me, no one’s paying me for this kind of emotional labor.”
His lips twitched—just barely. Not a smile. Not quite. But something close.
Still, he didn’t back down. “What do you know about him?”
“Enough to stay,” you answered simply, dropping onto the couch and toweling off your hair. “Enough to know he sleeps better when I’m here. Eats better. Talks more. Still leaves his laundry everywhere, but that’s apparently not fixable.”
Damian stood frozen, like he was running your answer through a thousand internal filters.
Eventually, he moved to sit—perching like a hawk on the armrest across from you, expression still wary but less… militant.
“So you know what he does,” Damian said stiffly.
“It’s how we met,” you replied, reaching for the remote. “He was horrible at keeping the whole alter ego a secret.”
“Are you trained?” he asked next.
“To deal with him? Yes.” You shot him a grin. “To fight? Not really. But I have excellent aim with a frying pan.”
For the first time, a snort escaped him—quick and unintentional. And then: “I suppose you’re tolerable.”
“That’s the nicest thing anyone under five feet has said to me.”
Damian frowned. “I’m ten.”
“Still under five feet.”
He huffed but stayed where he was, and after a moment, reached for the coffee table and grabbed the half-finished puzzle you’d been working on. Without asking, he began fitting pieces into place with alarming precision.
An hour later, Jason came home through the fire escape, expecting silence—or maybe the sound of you watching reruns, bundled up in one of his old shirts.
What he didn’t expect was the sight of you and his youngest brother sitting side by side on the floor, surrounded by puzzle pieces and popcorn, mid-argument about whether Red Hood could beat a grizzly bear in a fight on pure strength alone.
He stopped in the doorway and stared.
Damian glanced up. “You’re late.”
Jason blinked. “You broke in.”
“He made popcorn,” you said helpfully, tossing a piece into your mouth.
Jason pointed between the two of you. “What the hell is happening?”
“She’s tolerable,” Damian said, as if that answered everything.
Jason groaned. “I leave for two hours…”
“And you almost lost your popcorn privileges for keeping me hidden,” you added, smirking at him. “Apparently, I’m a national security threat.”
Jason pinched the bridge of his nose, muttering something about Wayne surveillance equipment and upgrading the locks to keep out demons.
But secretly?
He didn’t mind the sight of the two people he cared about most, sitting there together and getting along.
He’d just never admit it out loud.
