At first, it was subtle.
Kensi, Sam, and Deeks weren't always the most observant people when it came to personal matters—well, except maybe Kensi when she wanted to be—but when it came to Callen and Nell, something was different.
It wasn't in anything obvious, but it was in the small things.
The way they interacted felt… more natural, more fluid. There was a new kind of ease between them, something quiet and unspoken.
Sam noticed how Callen didn't linger at the office as much at the end of the day, instead slipping out almost as soon as Nell did. Deeks caught the way Callen's expression softened whenever Nell walked into the bullpen. And Kensi, ever the observant one, had picked up on the subtle glances they exchanged, the quiet way they seemed in sync without needing words.
Something was going on.
But neither of them were talking about it.
Not to anyone else, anyway.
That was what made them curious.
It wasn't until Friday night, after a long day, that the three of them sat together at the bar, beers in hand, and finally addressed it.
"You guys notice something's up with Callen and Nell?" Deeks asked casually, taking a sip of his drink.
Sam gave him a look. "You just now figured that out?"
Kensi smirked. "I clocked it a while ago."
Deeks huffed. "Well, excuse me for letting them have their privacy before assuming something."
Sam shook his head, but his tone was thoughtful. "They're different now. Not in a bad way, just… something's changed."
"They're probably figuring it out themselves," Kensi said, taking a sip of her beer. "Which is why they're keeping it quiet."
Deeks leaned on the table, watching the door as if Callen and Nell would walk in together and confirm it for them. "So, what, they're just sneaking around? Taking turns at each other's places like some kind of secret rendezvous?"
Kensi shrugged. "I don't think it's sneaking. I think they just like being around each other."
Sam smirked. "Callen's terrible at sneaking."
Deeks snorted. "Yeah, he's all 'silent lone wolf,' but the guy has no poker face when it comes to people he cares about."
They sat with that for a moment.
Then Kensi sighed. "We're not saying anything, right?"
Deeks raised a hand. "Nope. I like my life, thanks."
Sam nodded. "They'll tell us when they're ready."
Kensi smirked. "And until then?"
Deeks grinned. "We watch and take bets."
Sam just shook his head.
And across the city, in a quiet apartment, Callen and Nell sat curled up on the couch, reading by soft lamplight, unaware—or perhaps very aware—that their friends were onto them.
And neither of them minded one bit.
