The Avengers’ briefing room has never been a place for dignity, but today it seems to be actively hostile to it. Tony is half-reclined in his chair like a man awaiting grapes, one ankle propped over the opposite knee, hands laced behind his head as if this is less a tactical meeting and more an unfortunate interruption to his day. Clint is rocking back on two legs of his chair, testing the limits of both physics and Steve’s patience with the kind of idle curiosity that suggests he is perfectly willing to eat carpet if it means proving a point. Steve, for his part, is pretending not to notice, posture straight and expression carefully neutral, as if he looks official enough that the room might follow suit. Bruce is standing off to the side, tablet in hand, reading something with intense focus. This usually means he is trying very hard not to be involved.
Thor stands near the window. He hasn’t claimed a chair. He rarely does. Arms crossed, weight evenly balanced, he looks less like part of the team and more like a guest who wandered in from an entirely different genre, something older, grander, and significantly less fluorescent-lit. The city reflects faintly in the glass behind him, all sharp angles and motion, and he regards it with the distant patience of someone used to watching worlds move without him.
Natasha gestures to the screen. “This is a donor gala,” she says. “Very high profile. International press. Political money everywhere.” On the screen: chandeliers, marble floors, people in black tie smiling like they’ve never been told no in their lives.
Tony squints. “Oh, good. Rich people.”
“There’s chatter,” Natasha continues, unfazed. “We don’t know what yet, but someone we care about will be there, and it’s a closed guest list.”
Steve nods once, already slotting the information into place. “So we need someone inside.”
“Inside and unremarkable,” Natasha says. “No weapons. No armor. Formalwear.”
Clint grimaces, rocking a little harder on his chair. “This keeps getting worse.”
“We need a woman,” Natasha says. There’s the briefest pause. Not a dramatic one. Just the kind where the answer has already been decided by committee and no one has officially said it out loud yet. The air settles around the assumption, easy and familiar.
Thor turns from the window. “I can.” Two words calmly delivered.
The reaction is immediate and loud. Clint chokes, chair legs slamming back down as he catches himself on the table. Tony lights up like he’s been handed a gift he didn’t know to ask for. “Yes. Absolutely yes. I demand this.”
Steve rubs his face with one hand. “Thor—”
Thor blinks at the room, already laughing. Something in his expression shifts, not away from the idea, but toward the response. Toward the shape the moment has taken without him. He adjusts seamlessly, like a dancer changing steps mid-song, and smiles. “Relax,” he says, spreading his hands in a gesture that reads as both placating and grand. “I am jesting.”
Tony’s shoulders slump in exaggerated disappointment. “Oh. Boo.”
“I merely wished to ensure all options were considered,” Thor continues, tone light now, exaggeratedly noble. He inclines his head toward Natasha, solemn as a knight swearing fealty. “Truly, I would never presume to outshine Agent Romanoff at her own specialty.”
Natasha arches a brow. “Never?”
“Perish the thought,” Thor replies gravely. “You would destroy me.”
Clint grins. “Yeah,” he says. “That checks out.”
Bruce laughs, the tension easing out of his shoulders like he’s been waiting for permission. Steve exhales and lets the moment go. The room settles again, the disruption neatly folded away into something manageable. “I’ll go,” Natasha says. “It’s fine.”
“Of course,” Thor agrees immediately, bowing his head in mock deference. “You will be magnificent.”
Tony claps his hands together. “Okay, but I’m still putting this in the suggestion box.”
The conversation moves on, sliding effortlessly into logistics and exit strategies, and how much damage Clint is legally allowed to do to a tie. Thor steps back toward the window. The smile lingers just long enough to sell the performance. When it fades, it does so quietly, like it was never meant to be examined. He folds his hands behind his back, posture immaculate, gaze returning to the city beyond the glass. Natasha watches him from the corner of her eye. He doesn’t look disappointed. Which, somehow, is what makes her sure that he is.
The briefing winds down the way it always does: not with a clear end, but with a gradual thinning. Chairs scrape back. Bruce mutters something about files he’ll send later. Clint is immediately intercepted by Steve over the tie comment, already protesting his innocence. Tony drifts toward the door mid-sentence, still talking as if the room will simply follow him out of habit.
Thor remains by the window. He doesn’t move until most of them have filtered past him, the space around him widening as the room empties. The city beyond the glass has shifted, light changing, clouds sliding slowly between the buildings. He watches it with the same careful distance he brought to the meeting, like he’s content to be the last thing in the room that hasn’t decided where it’s going next.
Natasha gathers her things with practiced efficiency. Tablet tucked under her arm, jacket slung over one shoulder. She pauses when she reaches the door, glances back. Thor hasn’t turned. “You busy later?” she asks.
He does then, brow lifting slightly, attention snapping back with polite focus. “I had not planned to be.”
“Good.” She nods once, as if confirming something to herself. “You’re coming with me.”
Thor blinks, brows furrowing in confusion. “To the gala?”
“No,” Natasha says, already halfway back into the room. “Before.”
He studies her for a moment, searching her face for the joke she hasn’t made. “And what would my role be?” he asks carefully.
She shrugs, casual as breathing. “You’re a prince. You’ve been to these things. You know what matters.”
A pause; it’s small, nearly invisible. The kind that lives entirely in posture rather than expression. “If you wish,” Thor says at last.
Natasha’s mouth twitches, just barely. “I do.” She turns and heads for the door without waiting to see if he follows.
After a beat, Thor does. He matches her stride easily, hands folded behind his back again, expression settled into something neutral and composed. If there’s anything else there, anticipation, curiosity, something softer, it stays carefully unspoken. From the outside, it looks like strategy. Natasha doesn’t look back.
The dress shop smells faintly of perfume, fabric cleaner, and something floral that’s trying very hard not to be overwhelming. It’s quieter than Thor expected. Soft music plays somewhere overhead, indistinct enough that it fades into the background almost immediately. Racks of dresses line the walls in careful gradients of color, arranged with the kind of deliberate precision that suggests someone has thought very hard about how eyes move through a space like this. Light pools warmly over mannequins posed in permanent, elegant mid-gesture.
Thor stops just inside the doorway. He does not cross his arms, but he comes close. His hands hover at his sides before settling, clasped neatly behind his back instead. His posture firms, spine straightening as if bracing for impact, expression smoothing into something polite and unreadable. Natasha clocks it instantly, but doesn’t comment. “This won’t take long,” she says, already moving farther into the store. “I know what I’m looking for.”
“I am certain you do,” Thor replies, tone carefully neutral.
She pulls a dress from a rack: sleek, black, understated in a way that suggests expense rather than effort. Holds it up against herself, considering the mirror. “What do you think,” she asks lightly. “Black?”
Thor hesitates long enough that it almost reads as refusal. “…Dark green,” he says finally.
Natasha glances at him. “Hmm?”
He shifts his weight, gaze flicking briefly to the mirrors, the lighting, the other dresses nearby. Still not quite comfortable, still standing like he’s waiting to be dismissed. “You want to look like someone trying to stick out,” he continues, voice even. “Black would blend in too much.”
She considers that. Really considers it. Then she reaches for a deep green dress two racks over, rich and dark and unmistakably intentional. “Huh,” she says. “Okay.” Thor inclines his head once, as if the matter is settled, and promptly goes quiet again.
Natasha disappears into a fitting room. Comes back out. Tries another dress. Then another. The sales associate hovers at a respectful distance, clearly recalibrating her understanding of this shopping trip. Natasha catches Thor watching the hems. Not openly, not eagerly, but with the sharp, assessing eye of someone used to rooms full of people pretending not to look at one another. She turns slightly. “Thoughts?”
He pauses, then exhales through his nose, just barely. “That one would photograph poorly,” he says. “The fabric reflects light unevenly.”
She blinks. “It would?” She never cared about how well a dress would look in pictures, as the goal was not to be photographed. The comment reminded her that she wanted to look like someone who would care about such a thing.
“Yes. The cameras will be everywhere.”
She swaps it out for another dress. This one is too severe. Another is too soft. Thor stays mostly silent, offering commentary only when asked: measured, precise, unexpectedly thoughtful. “You move differently than most of the attendees,” he says at one point. “Something with structure will read as confidence instead of armor.”
Natasha hums, amused. “You’ve done this before.”
He almost smiles. “More times than I would like,” he admits.
She doesn’t push; instead just hands him another hanger. “What about this?”
Thor studies it. The cut. The color. The way it would move in a crowd. “That,” he says after a moment, “would make them look twice.”
Natasha nods slowly. “I like that.” By the time she heads back toward the fitting room again, Thor has shifted closer to the racks. Not much. Just enough to suggest he’s stopped waiting to leave. The discomfort hasn’t vanished, but it’s loosened. When Natasha disappears behind the curtain once more, Thor’s gaze follows the fabric instead of the door.
Natasha steps out of the fitting room in the green dress. It fits well. Too well, honestly, clean lines, structured shoulders, the kind of cut that suggests intention without screaming for attention. She turns once, assessing the way the fabric moves, then glances toward the mirror again. “The hem’s too long,” she says, more statement than complaint.
Thor looks up automatically. His gaze drops, not in the way that would make the sales associate hover closer, but with the clinical focus of someone evaluating construction rather than form. He crouches without thinking, fingers hovering near the edge of the fabric before he catches himself and draws them back. “Yes,” he says. “About this much.” He pinches the air, precise.
Natasha watches him for a beat. Then lifts the hem just enough to match his estimate. “Show me.”
Thor sighs, soft, exasperated, clearly at himself, and lowers to the floor. One moment he’s standing there, distant and politely disinterested; the next he’s seated cross-legged on the carpet, the green fabric pooled around his hands as he measures with careful fingers. “I do not care about this,” he informs the floor solemnly.
Natasha bites back a smile. “Obviously.”
Thor adjusts the fabric another fraction of an inch, expressing intent. “Any higher and it will disrupt the line when you walk. Any lower and it will drag.” He tilts his head, reassessing. “That should be sufficient.” The sales associate stares at him like she’s witnessing a minor miracle.
Natasha looks down at him. “You’re very sure.”
“I am,” Thor replies, without hesitation.
There’s a pause. Then, as if forgetting where he is, his poster loosens. His hands remain on the fabric, but something cautious slips away. “I used to do this,” he says, voice quieter now, almost absentminded. “With my brother.” Natasha doesn’t move. “We would steal pins from the sewing room,” Thor continues, gaze unfocused as he studies the hem as if it belongs to another time entirely. “Mother would pretend not to notice when they went missing.” His mouth curves faintly. Not quite a smile. “We both knew we would never actually wear them,” he says, “But it was enjoyable to pretend.” The memory settles into the space between them, soft and fragile as the fabric in his hands.
Thor releases the hem at last and leans back on his palms, looking up at Natasha as if only now remembering the present. “That will need to be taken up,” he says briskly, professionalism snapping back into place, “But the color is correct.”
Natasha nods. “Good,” she says. “I trust you.” Thor blinks at that.
The sales associate snaps her fingers as if suddenly remembering she has a job to do. “Oh—right!” she says, voice bright, stepping closer with a tape measure in hand. “I should probably, uh, help you with this.” Thor stiffens slightly. He sits a little straighter on the carpet, hands hovering over the hem, fingers flexing as though ready to retreat. His gaze flicks to the associate briefly, polite but firm, and then back to the fabric.
Natasha glances down at him, lips twitching in quiet amusement. “Don’t let her intimidate you,” she murmurs. Thor inclines his head once, eyes narrowed slightly, not unfriendly, just cautious. He’s not leaving, not yet, but he’s no longer leaning in as he was moments ago.
The sales associate kneels beside him, measuring, shifting pins in her hands. Thor’s posture stiffens further, shoulders subtly rigid, though his hands remain near the fabric, hovering, ready to assert his opinion if asked. “You know what you’re doing,” Natasha says softly, still watching him. “I’m fine letting you lead here.”
Thor’s jaw tightens almost imperceptibly. He offers nothing in words, only a small nod. His face is calm, neutral, the careful mask of composure he’s perfected over centuries slips on again like armor, though faint traces of the previous warmth linger in his posture, in the slight attentiveness of his hands. The three of them, Thor, Natasha, and the associate, work in quiet, a delicate rhythm forming. Thor doesn’t speak unless prompted, doesn’t smile, doesn’t comment, yet his presence clearly shapes the decisions being made.
The sales associate leaves, footsteps fading into the hum of the shop. Thor exhales, long and deliberate, finally allowing himself a fraction of space on the carpet, hands resting lightly on the hem. The fabric feels familiar in a strange way, coaxing the memory forward. “…There was a time,” he begins slowly, voice low, almost hesitant, “my brother… he had the idea. That I should… wear a dress.”
Natasha doesn’t comment, letting him speak. Thor shifts, leaning slightly forward, voice quiet. “…We were… very serious about it. This was the only time we could ever truly buy a wedding dress for one of us.” He pauses, a faint twitch at the corner of his mouth, a ghost of a smile. “…And so we went shopping, argued over every possible detail. Color. Length. Lace. Sleeves. Necklines. He mocked me constantly—called me a… skank, I think, once.” His lips curved into a smile at the memory, “I argued back.” He leans further into the story, hands idly adjusting the hem in front of him, the motion unconscious. “…We invited Mother along. Dragged her with us. She looked ready to strangle both of us by the end, and still… we argued. Until the very last decision, when we finally, finally, agreed.” Thor exhales again, a little heavier this time, eyes tracing the folds of the dress. “…It was… childish. Silly. But,” His voice softens, a quiet warmth beneath the amusement, “we were careful. As if it mattered, and in a way, it did. For that moment.”
A pause, then Natasha says softly, almost gently: “You were close.”
Thor blinks, caught off guard. “Sometimes,” he admits, quickly correcting, “that was a time we were. Other times, we drove each other mad. A result of spending centuries together, knowing exactly what would provoke the other… and doing so anyway. Trying to cause trouble, while avoiding consequences.” He freezes, hands still on the hem. He realizes he has said too much. He’s admitting not just to wearing a wedding dress, but to arguing with his brother over it, dragging their mother along, taking it seriously, all of it silly, childish, utterly intimate. His posture stiffens, hands folding neatly in his lap. “It was trivial,” he says, a little too fast, “A silly story.” Natasha just watches, quiet and unjudging. Thor tucks the hem aside, sitting up straighter, retreating into the careful composure he’s worn all day, but the memory lingers, soft and sweet, tucked into the folds of the dress and the warmth of the shop, a little treasure he has shared, briefly, accidentally, and yet completely.
Thor helps hold the dress in place while the sales associate notes the alterations. A small stack of tags, receipts, and measuring tape accumulates around them. He moves with precision, efficient, offering a few final adjustments, but his voice is clipped, polite, and neutral. Natasha completes the purchase, confirming pickup and alterations with the associate. Everything is scheduled and accounted for. Thor folds his hands behind his back, standing just outside the dressing area, eyes fixed on the floor, posture rigid. He doesn’t speak beyond the occasional “Yes” or “That will suffice,” and he doesn’t volunteer any further commentary, even when Natasha gives him a small smile of thanks for his input.
On the walk back to the car, the silence stretches comfortably between them. Thor keeps his gaze ahead, hands behind his back. He walks slowly, deliberately, as if making sure the world can’t pull him in any unexpected direction. Natasha chats quietly about logistics, but he responds only when necessary, his voice flat and measured. His earlier warmth, his humor, even his curiosity, all neatly tucked away behind a wall of calm neutrality.
By the time they reach the team, the contrast is stark. Tony is fiddling with some gadget. Clint is leaning against a console, pretending not to notice. Steve is mid-discussion with Bruce. The bustle of the team feels distant to Thor. He steps into the space but remains detached, shoulders slightly tight. He doesn’t volunteer information, he doesn’t laugh at Tony’s joke, and he doesn’t comment on the room. His hands are folded behind him, posture perfect, expression unreadable. Natasha glances at him once, just enough to note the subtle retreat, the quiet shutdown. She lets him be, and Thor moves through the room like a shadow in motion, present, but only just.
A couple of days later, the tower is bustling with final preparations. Natasha steps out of her quarters. The green dress fits her perfectly: sleek, structured, just enough movement to carry her through the room without effort. The alterations Thor had suggested sit flawlessly; the hem precise, the shoulders crisp. The team freezes, or at least slows. Tony whistles, exaggerated. “Wow. Yep. That’s—yep. That’s very fancy.”
Clint straightens up, grinning. “Natasha Romanoff, you clean up nice.”
Steve nods once, approving. “Professional and sharp. Exactly what’s needed.” Natasha smirks, but it’s quiet, self-contained. She walks past, letting them admire the look without a word.
Thor watches her. It’s a subtle shift. A flicker in his eyes, just enough for Natasha to catch it. Not pride exactly, not boastful, but a spark. A recognition that he made the right choices: the fabric, the cut, the hem, and that the result is perfect. He doesn’t speak. He doesn’t move differently. There’s no nod, no gesture, no acknowledgment. The pride is tucked away neatly, behind measured composure. Natasha notices. Only for a heartbeat. She doesn’t acknowledge it, but she remembers it. She steps fully into the light, letting the dress move with her, letting the team see it in motion, letting the moment exist just as it is. Thor’s eyes follow her, careful, restrained, and honest without needing words. It passes. She moves on to the final mission prep. He folds his hands behind his back. The spark remains, hidden, quietly warm. No one else notices.
Natasha returns to the tower after the mission. Her hair is pulled back, and the green dress is ruined. Torn in several spots, smudged with dust and faint streaks of something that might have been coffee or blood. She collapses onto the couch without changing and presses the remote. The screen flickers to life. “Say Yes to the Dress.” It’s mind-numbing. Easy. She doesn’t have to think, doesn’t have to be careful. Just background noise. The soft chatter of consultants, the hiss of fabric being fussed over, brides sighing, exhaling relief or frustration, it’s mechanical, repetitive. Comforting in its predictability.
Thor enters quietly, taking in the scene. His eyes flick to the ruined dress, then the screen, then Natasha. He hesitates. Not because he disapproves, he’s seen worse, but because he recognizes it. “Mine,” he says softly, voice low, almost lost in the hum of the television, “was in a similar state.” Natasha glances at him, lips twitch, she doesn’t respond. Thor’s gaze drifts back to the screen, to the brides and their gowns, and the corners of his mouth lift, just slightly. Not a full smile, never that, but a small acknowledgment. Natasha leans back, letting the episode play. The couch dips under her weight. The dress is torn and imperfect. The television chatters on. Thor watches, softly, without comment nearby.
