It was early on a Saturday morning, and the office was quiet, bathed in soft light from the rising sun slanting through the tall windows. Callen stepped through the wooden doors, the faint echo of his footsteps the only sound in the stillness. He wasn't here for a case—not today. He had left a pair of Lakers tickets in his desk drawer, and he and Sam had plans to catch the game that night. It was supposed to be a quick in-and-out.
He made his way through the bullpen, the usual hum of activity noticeably absent. Just as he opened his drawer and spotted the edge of the bright yellow tickets, a strange sound floated down from upstairs—an odd mix of static, clicking, and shuffling.
Callen paused, brow furrowing. Nobody was supposed to be here.
Quietly, he slid the drawer shut and started up the stairs toward Ops, instinct and curiosity kicking in. The mechanical doors hissed open and revealed a scene so unexpected he had to blink twice.
Nell Jones sat cross-legged in the middle of the Ops floor, surrounded by twisted cables and several open laptops. A tangle of wires snaked across the floor around her like ivy, blinking lights flickering from makeshift connections. She was wearing oversized headphones, completely lost in whatever she was doing—nodding her head in rhythm to the music as her fingers flew across a keyboard. One of the screens was filled with streaming lines of code; another showed some kind of encrypted network diagnostics.
Callen stepped in slowly, unsure whether to laugh or be concerned.
"Nell?" he said.
Nothing.
He tried again, louder this time. "Nell!"
Still no response. She just kept nodding to the beat, lips moving slightly like she might be mouthing lyrics or counting packet transfers. Callen shook his head, half amused. He stepped closer, crouched beside her, and gently tapped her shoulder.
Nell let out a startled shriek and jumped, almost knocking over a laptop as she yanked off her headphones.
"Callen!" she gasped, pressing a hand to her chest. "You scared the life out of me!"
He chuckled, raising his hands in mock surrender. "Sorry. I called your name—twice. You were in the zone."
She let out a breath, laughing softly, the flush of surprise lingering on her cheeks. "Yeah, I guess I was. I'm tracking a weird data anomaly from one of our satellite relays. Figured I'd poke around a little before it became a Monday morning problem."
Callen glanced around at the chaos on the floor, then raised an eyebrow. "This is what your 'poking around' looks like?"
Nell grinned, brushing a strand of hair back with her knuckle. "Welcome to my version of a Saturday morning."
He tilted his head, taking her in with a half-smile, a flicker of something warm in his eyes.
"You need a hand with any of this?" he asked, almost teasing—but not entirely.
Nell paused and looked at him, a slow smile spreading across her face. There was something behind it—affection, amusement, a little fondness that lingered in her gaze just a second too long. Then that quiet, knowing look she had down to a science. One that said, you're sweet for offering, but this is so far outside your wheelhouse you might short-circuit something just by breathing near it.
Callen caught it and laughed, his grin tugging wider. "Yeah, okay. Not really my thing, huh?"
She tilted her head slightly and arched an eyebrow, lips quirking like she was trying not to laugh again.
"I am good at knots," he offered, gesturing to the wires. "And I fetch a mean cup of coffee."
That did it—Nell laughed, soft and real, her shoulders relaxing a little.
"Well," she said, voice a touch lighter now, "I could definitely use some coffee. If you don't mind."
He lingered just a beat longer, eyes holding hers.
"I've got you covered," he said, voice low and warm. "One tactical-grade caffeine deployment coming right up."
As he turned and headed toward the stairs, he looked back at her - tucking a loose lock of hair behind her ear as she slipped her headphones back on, a small smile playing on her lips.
Callen moved downstairs toward the coffee machine, his thoughts drifting back to Nell. He couldn't shake the image of her upstairs, completely absorbed in her work, tangled in cables with headphones on. There was just something about the way she got lost in it all, so focused and calm.
As the coffee brewed, Callen smiled to himself. He wasn't sure why it felt important, but offering to get her coffee had felt... different. There was a quiet connection there, a moment between them.
The coffee machine clicked off, snapping him from his thoughts. He grabbed the cup and headed upstairs, finding Nell exactly where he left her—surrounded by cables, headphones on, working with a focus that was all hers.
He set the coffee down beside her, and she glanced up, smiling brightly. "You're a lifesaver."
Callen gave a small grin, leaning against the table. "Anything for you, Nell."
Nell's smile lingered as she took a sip. There was something unspoken in the moment, a quiet understanding between them. Callen watched her for a beat, then turned to leave, feeling like maybe he wasn't done thinking about her just yet.
