The bullpen had mostly emptied out, the usual end-of-day shuffle echoing through the quiet halls. Phones stopped ringing, lights dimmed, and the clatter of keyboards had given way to the more subdued sounds of people gathering their things, ready to call it a night.

Callen stood at his desk, the long, slim black box in his drawer catching his eye once more. He'd been sitting on it for a few days now, waiting for the right moment. It wasn't flashy. It wasn't wrapped. But it had taken him more time than he cared to admit to find the right one—something that wasn't just a gift, but something that meant something.

He pulled it out, glanced around the mostly empty room, and slipped it into his back pocket.

Nell was still upstairs in Ops, wrapping up. He wasn't the waiting-around type, not even for birthdays. So instead of sticking around, he left the gift behind the way he knew she'd appreciate it—no fuss, no audience.

On his way out, he ducked down the side hall and spotted her bag slung on a bench by the locker alcove. Quietly, he placed the box on top, angled it so she wouldn't miss it. Nothing else. No card, no note. Just the box and a sticky note with her name.

Then he turned and left.

Twenty minutes later, Nell came downstairs, footsteps light but distracted. She'd managed to avoid most of the attention about her birthday, and that was how she liked it. Birthdays hadn't really felt like celebrations in a while. Not with family always far away, and Eric off at some tech conference this week. She'd figured it would be another quiet night, maybe a glass of wine, maybe one of those solo walks along the beach she told no one about.

Then she saw the box.

Her steps slowed.

She looked around instinctively, but the bullpen was quiet. Her brows furrowed slightly, and she picked it up. It was simple—matte black, no embellishment. Just her name, scrawled in small block letters on a yellow sticky note stuck to the top in handwriting she instantly recognized.

Callen.

Curiosity pulled at her as she opened it, slowly lifting the lid.

Her breath caught.

Inside was a knife. Clean lines. Narrow blade. Perfectly balanced. Practical, elegant, and unmistakably deadly. It wasn't flashy, but it was precise. Thoughtful. Exactly her style.

And it wasn't just a weapon—it was a memory.

That day in the boat shed came rushing back—the panic, the struggle, the instinct. That old knife she'd carried ever since had become something of a quiet talisman, worn and dulled but part of her.

This was more than a replacement.

It was a recognition.

A gift that said something.

She stood there for a long moment, running her thumb lightly along the edge of the handle, feeling the weight of it in her palm. Not just the steel, but the intention.

Then her gaze shifted toward the exit, where he'd disappeared not long ago.

She smiled, small and private.

"Thank you, Callen," she whispered to no one.

Then she slid the box into her own bag, the knife now hers in every way that counted.

The next morning, the bullpen buzzed with the usual energy—keyboards clacking, phones ringing, coffee being passed around like currency. Callen stood at his desk, flipping through a file, the picture of casual focus. But his eyes flicked up the moment Nell walked in.

She moved with her usual quiet confidence, a folder tucked under one arm, her auburn hair catching the light as she passed through the room. Their eyes met for only a second—but in that second, everything landed.

Nell gave him the smallest of smiles—subtle, knowing, just for him. A thank-you without words.

Then, with deliberate grace, she flicked her gaze downward—just briefly—toward the top of her boot, where the edge of a dark leather sheath peeked out.

Callen didn't react at first. Not outwardly. But there was a twitch at the corner of his mouth, the kind that hinted at quiet satisfaction. He didn't need acknowledgment, didn't expect it. But this?

This was better.

A nod. A look. The knowledge that the knife—the gesture—meant something.

Then Nell turned back to her work, and Callen went back to his, the silent thread between them stretched just a little tighter.

She carried the knife now, tucked close, not just as a tool—but as something more. A reminder that someone had seen her, understood her, and without ever saying the words, had given her something she didn't even know she needed.
