Outside, the backyard was still buzzing with energy. The halftime show was in full swing, and Kensi and Deeks were deep in a passionate debate about the greatest performances of all time.

"I'm just saying," Deeks was gesturing wildly as Callen stood up, "Bruno Mars had the perfect blend of vocals, choreography, and stage presence. The man's got range!"

Kensi scoffed. "Oh please. You still haven't admitted that Beyoncé ran that entire show even when Coldplay was technically the headliner."

Callen smirked at their back and forth but wasn't paying too much attention. His eyes had flickered toward the house a few minutes ago when Nell had quietly excused herself to go inside. He wasn't sure why he noticed—he just did.

Feeling like another beer wouldn't hurt, and maybe using that as an excuse, he got up and made his way into the house.

The noise from the backyard faded as Callen stepped into the kitchen, the warm glow of the pendant lights casting soft shadows against the counters. He pulled open the fridge, reaching for a beer, but movement in the hallway caught his attention.

Nell.

She was rolling her sleeves down as she walked toward the kitchen, her movements easy, unhurried. The casual setting suited her, but something about the way the dim light softened her features made him pause for half a second longer than necessary.

She noticed him at the same time, a knowing smile tugging at her lips. "Taking a break from all the football trash talk?"

Callen smirked, grabbing two beers before nudging the fridge door shut. "Just refueling." He held up the bottles in a mock toast. "Though if I'd known you were sneaking off, I might've assumed you were planning some second-half strategy."

Nell let out a soft laugh, stepping into the kitchen fully. "No strategy, just needed a minute." She leaned against the counter, her fingers lightly tapping against the cool surface. "Don't tell Sam, but I think I've reached my limit on barbecue-scented air."

Callen chuckled, stepping toward her as he handed her one of the beers. "Your secret's safe with me."

She took it, her fingers brushing his for just a fraction of a second longer than necessary. Maybe it was nothing—but Callen noticed. The briefest hesitation before she pulled away, the way her gaze flickered up to meet his.

Nell twisted the cap off her beer, taking a slow sip before giving him a sidelong glance. "Still, it's been a good day. Even if the Patriots are winning."

Callen raised an eyebrow, feigning offense. "Should I just hand over my jersey now?"

"Tempting," she admitted, setting her beer down with a casual shrug. "But I think I'll let you sweat it out a little longer. Watching you pretend you're not worried is more fun."

He scoffed. "I'm not worried."

Nell hummed, tilting her head slightly as she studied him. "Really? Because your posture says otherwise."

Callen smirked, stepping just a little closer. "And what exactly does my posture say?"

She pretended to assess him, tapping a finger against her chin. "That you're way too cool to admit you're nervous." She let the words hang for a beat before her lips curved into something softer. "But deep down, you know there's a chance you'll lose."

Callen exhaled a quiet laugh, shaking his head. "You keep telling yourself that, Nell."

He expected her to fire back instantly, but she didn't. Instead, she just smiled—slow, amused.

And just like that, the space between them felt different.

The teasing was still there, but there was something else underneath it. Neither of them moved, not really, but Callen was suddenly aware of how close they were. Close enough that he could pick up the faintest trace of whatever perfume she was wearing. Close enough that if he shifted even slightly, the air between them would disappear completely.

Nell seemed to notice it too.

Her fingers curled around her beer bottle, but she didn't break eye contact. For a moment, it felt like something was balancing on the edge—something neither of them was quite ready to name.

Then, as if sensing the shift at the exact same time, Nell let out a quiet breath and stepped back. Smooth, easy, like nothing had happened.

"Come on," she said, her voice light as she nodded toward the backyard. "Let's get back before Deeks tries to convince Kensi that Coldplay was an underrated halftime act."

Callen let out a breath of his own, smirking as he raked a hand through his hair. "Too late for that."

As they stepped outside, the backyard noise crashing back into focus, Callen took a sip of his beer and glanced at Nell.

For the first time tonight, the game wasn't the only thing keeping him on his toes.
