A/N: It's back! Thank you for being patient for an update. This one is short, I apologize. But we needed this happy little moment. Enjoy!

Jamie whips the dish towel over his shoulder in time with the emphatic version of New York, New York he's whistling just before he sets another pot on the counter to be put away. He feels the look Danny gives him as he takes the stack of clean dishes and moves to put them up in the cupboard.

"What's with the whistling?"

Jamie glances up from the sink and over at his older brother. "What?"

"I've never known you to whistle. You're whistling like you're deranged," Danny accuses. "What gives?"

"Want me to sing instead?" Jamie briskly snaps his fingers a few times, directing a spirited nudge against Danny's arm each time. "If I can- make it there-"

Danny jerks away and Jamie cuts himself off with a throaty chuckle, rocking back a step when his brother shoves him aside.

"Cut it out, kid."

Jamie smiles as he rinses a wine glass. "Lighten up, Danny."

"Lighten up, he tells me," Danny muses. "Last Sunday, you're practically on the verge, and today you're whistling Frank Sinatra like a nutcase."

"I'm washing dishes," Jamie laughs.

"Mm-hm. So you must really like your new partner."

Vague confusion flickers across Jamie's forehead. "Who, Benfield?" Then he shrugs. "He's alright."

"Because last week you seemed pretty bummed out about a certain other partner transferring."

Jamie nods. "Yeah of course. Sucks to lose a solid partner."

"Guess you're over that loss considering this creepy good mood."

With a scoff, Jamie shuts off the water at the sink and drags the towel off his shoulder to dry the glass. "Just tell me what you're so suspicious about, Danny."

"I'm suspicious about your smug face."

With another laugh, Jamie glances down and doesn't even bother taming his smile.

"Huh?" Danny reaches out and taps his hand against Jamie's cheek. "Huh?" He jokes. "Who's the girl?"

"Girl?"

"Someone's got you all unhinged," he reasons. "You're gonna tell me it's not a girl who's got you whistling? Whistling like a guy who just got some?"

"Nice, Danny," Jamie mutters through a smirk.

"That's the only acceptable reason for a man to be whistling a tune."

A soft laugh escapes Jamie's chest and he cuts his brother a look. His tongue quickly swipes his bottom lip before his lips draw together and his whistling picks up where it left off on the jazzy melody. An eyebrow flicks playfully as he reaches up in the cabinet to replace the last dry glass, then shoves Danny on the shoulder.

"I knew it!" Jamie hears as he passes by.

"I didn't say anything."

"Fess up, kid!"

And then feels the weight of Danny pushing down on his shoulders before he jumps against his back. "Get off me," Jamie laughs, twisting away to fend off Danny's attack.

But his brother easily gets him in a playful headlock with an arm hooked around Jamie's neck. They scuffle across the kitchen floor, Jamie too entertained by Danny's persistence to truly fend him off.

"Arm drag, old man!" Jamie shouts, threatening to haul his brother over his shoulder to the floor.

"You wish!

"Hey, whoa!" Erin's voice rings out over them. Her quick footsteps are halted when she nearly runs into her two brothers. "Separate. Adults are trying to walk here," she complains. "What's gotten into you two?"

Danny finally releases his hold on the younger Reagan when Jamie lifts up straight and checks Danny with his shoulder.

Danny exhales heavily. "The kid has a girlfriend and he's trying to keep it from the family."

"I'm not trying to keep anything from you!" Jamie spreads his hands and lets out an incredulous laugh. "You want to know too bad, Danny."

"Well, that's kind of my thing," he shrugs. But then he holds up his hand to reveal Jamie's phone. He must have slipped it from his pocket during their struggle.

"No, no, no, no-" Jamie rattles, letting out a hard breath. He glances up at the phone and suddenly a flare of genuine worry he wasn't expecting pulses in his chest. "Give it back."

Erin shifts her weight alongside Danny, crossing her arms over her chest. An amused smirk crests on her lips and Jamie shoots her a look in disbelief that she would endorse this.

"If you've got nothing to hide, you've got nothin' to hide, am I right?" Danny taunts.

Jamie considers the text message exchange he'd shared with Eddie earlier that afternoon, just before he left for Sunday dinner. Distinctly remembering a few of Eddie's requests for later that night, he swallows hard, then swiftly grasps Danny's arm and wrenches his phone back.

He slides his phone into his pocket, unflustered, and lowers his gaze to the older brother before his lips twitch. "I'm with Eddie," he admits. "We're together. Mystery solved, Detective. You feel better now?"

Danny slaps his hands together. "I knew it."

"You didn't know," Jamie accuses, his eyes narrowing.

"I knew." Erin offers a proud shrug. "I've known all along."

Jamie scoffs, his eyes rolling upward. "Please."

"So are we gonna get the full story?" Danny wonders. "Is this a real thing now?"

"Yes it's a real thing. And no, you will not get the full story."

"You two were doin' it on the job, weren't you?"

Jamie chuckles. "Get outta here."

"Does Dad know?" Danny presses.

Jamie slaps his hands on Danny's shoulders and moves him out of the way so he can pass by. "Have any more questions, talk to my lawyer." Then he plants his palm on the crown of Erin's head, jostling her a few times and makes his way out of the room.

"Did you just ruffle my hair?" His sister calls after him and he glances back to flash her a grin.

And he can only imagine the look his siblings exchange when Jamie's lips draw together once again and he turns to leave, trailing a whistling melody through his father's house.
