Thunderbolts HQ was not built for quiet people.

The second you walked in, the noise almost knocked you backwards.

Red Guardian arguing with Val. US Agent slamming weights around like people were watching. Ghost flickering in and out of visibility because she was bored. Bucky rubbing his temples like he regretted every career decision that led him here.

And you?

You stood in the doorway, silent as a shadow.

Nobody had heard you speak. Not when you were recruited. Not during evaluations. Not even when the medics asked questions.

You simply wrote things down or answered with hand gestures.

Everyone assumed you were mute.

Most didn’t care enough to ask why.

But one person noticed everything.

Yelena Belova.

She leaned her elbows on the table and stared at you with those sharp, mischievous eyes, like she was trying to solve a puzzle.

“Why do you never talk?” she asked, not rudely — just curious. You only blinked.

Bucky looked up from the mission file. “She doesn’t talk,” he said quietly, like it was a fact everyone already accepted. “Doesn’t mean I stop asking,” Yelena shot back.

You stayed still, hands folded in front of you, breathing slow so no one saw how overwhelmed you were.

Bucky glanced at you again, noticing the way your shoulders tensed, and said softly: “Let her be, Yelena. If she doesn’t talk, she doesn’t talk.”

Yelena rolled her eyes but shrugged. “Fine. But I will make you laugh someday,” she said to you, pointing playfully. “You cannot hide forever.”

Training Day

Val wanted to test you with the whole team.

“Non-verbal or not,” Val barked, “she’s on this team. And she has to prove she can keep up.”

You didn’t flinch. You stepped forward and waited.

Taskmaster went easy on you — at first. But you moved fast. Silent. Precise. You surprised them.

Until—

A sharp, sudden sound echoed across the training room: A metal plate crashing to the floor behind you.

It wasn’t loud to anyone else. But to you, it was like a gunshot.

Your whole body froze. Your throat locked. Your chest tightened painfully.

Ghost tilted her head. “Did we… break her?”

Yelena moved first.

“Hey,” she said softly, stepping toward you. But she noticed the tremor in your hands, the distant look in your eyes.

She slowed down.

Bucky caught on immediately. He walked around you, careful not to get too close.

“Grounding,” he murmured to Yelena, as if explaining. “She’s triggered.”

Yelena frowned, confused. “Triggered by what? She didn’t even get hit.”

Bucky nodded at you gently. “She’s not mute,” he said quietly. “She’s scared. That’s different.”

Your breath hitched.

Yelena looked at you again — really looked — and something softened in her expression.

“Oh,” she whispered. Not pity. Understanding.

She stepped closer, slow and calm, offering her hand — but not touching without permission.

“You don’t have to say anything,” she murmured. “I just need you to breathe with me.”

Her voice was warm. Soft. Safe.

You matched her breaths, shaky but trying.

The rest of the team watched silently as Yelena knelt in front of you, lowering herself to your level like you were the only person in the room.

When your shaking finally eased, she whispered:

“See? I knew you weren’t just being mysterious. You were hiding something real.”

You didn’t nod. You didn’t shake your head.

But you looked at her.

For the first time.

Really looked.

And she understood more from that single glance than from a thousand words.
