The smell of grilling meat filled the air as Callen stood near the edge of Sam's backyard, beer in hand. The sun was dipping lower, casting a warm glow over the gathering. The Super Bowl was still a couple of hours away, but the backyard was already buzzing with easy conversation and the occasional playful jab over team loyalties.

Dressed in his Patriots jersey over a T-shirt, Callen wore the relaxed confidence of a man who fully expected his team to win. He was mid-conversation with Aiden, who was stretched out in a lawn chair, sipping a soda and talking about life at military school.

"It's not as bad as I thought," Aiden admitted. "Strict, yeah, but I get it. Structure, discipline, all that."

Callen smirked. "Sounds like it's turning you into a real soldier."

Aiden rolled his eyes but grinned. "That's what my dad keeps saying."

At the grill, Sam glanced over, catching just enough of the conversation to look pleased before shifting his attention to the food. Then his eyes flicked toward the gate, and his grin widened.

"Looks like someone finally made it," Sam announced.

Callen turned just in time to see Nell stepping through the gate, a tray of cookies in her hands. She wasn't wearing a football jersey—just a casual top and jeans, effortlessly put together. He told himself he wasn't looking too closely, but the way she moved, the way she carried herself, made it hard not to.

Sam met her halfway, taking the tray from her hands. "Didn't expect you to bake."

"I figured I should contribute something," Nell said, tucking a loose strand of hair behind her ear.

Callen smirked as she turned, her eyes scanning the yard until they landed on him. She gave a small wave, her smile soft but knowing.

"Hey, Callen."

He lifted his beer in a lazy toast, eyes lingering on her just a second longer than necessary. "No Jets jersey today?"

Nell crossed her arms, her expression teasing. "Nope. Figured I'd give you one day to enjoy your Patriots delusion without interference."

Callen let out a quiet chuckle. "Generous of you."

Nell stepped closer, eyeing his jersey with a mock-critical tilt of her head. "I have to admit, you do commit to the bit. Very patriotic of you, Callen."

"You say that like you're surprised."

She arched a brow. "Not surprised. Just… entertained."

Something about the way she said it—light, playful, but with an edge of something else—made Callen pause for just a beat too long. He noticed the way the late afternoon sun hit her hair, the way she stood so comfortably in his space. It wasn't new, this easy rhythm they had, but tonight, it felt… different.

Before he could say something back, Sam clapped a hand on his shoulder, breaking the moment. "Come on, Callen, grab some food before Deeks eats everything."

Nell let out a soft laugh, shaking her head as she walked past him toward the picnic table. Callen took another sip of his beer, watching as she slid into an easy conversation with Kensi and Deeks. He told himself it was just a barbecue, just another Sunday, just another round of teasing with Nell.

And yet, as he pushed away from the table and made his way over to where she stood, he couldn't quite shake the feeling that maybe—just maybe—this time was different.
