"Let's me and you go have a ?" Danny stared down his kid brother sizing him up.

"Okay." Jamie pushed past Danny's partner, Jackie, and followed Danny into the nearby room.

sergeant Renzulli remained looking mildly miffed at the altercation, but knew the root of the reason was truly between brothers. Someone called his name, an old trainee he'd ridden with few years back. With a glance over his shoulder to the two Reagan brothers, he made his way to Conrad Peterings' desk.

Meanwhile behind closed doors, Jamie paced a few yards away from his big brother who watched him with a curious gaze. "So what's going on? What, you wake up and eat your Wheaties this morning or something?"

Jamie rolled his eyes, "Nothing's going on, Danny."

"Well, you could've fooled me." He huffed under his breath.

"This is all clearly stipulated in the guide book." Jamie, the ever formal one, began but was cut off by Danny's scoff.

"This is all clearly stipulated in the- what are you talking about? Do you even hear yourself? You sound like a Harvard law professor, not even a cop."

"Here we go." Same rhetoric. Same BS.

Danny raised his hands in exasperation. "Hey, the truth hurts."

Jamie turned towards Danny finally ready to fight this out. "I've been on the job over two years now, Danny. I have over 50 arrests and I have a successful stint working undercover." With each personal accomplishment, his courage and confidence swelled. "So you can stop lecturing me on what it means to be a cop."

"Well, look at you." Danny mocked. "Six months doing part-time undercover and now you're what? The freaking French Connection? What are you gonna do next? Replace the old man as commissioner?"

"What is your problem? What the hell did we ever do to you?"

"Who's we?" Danny's face fell in confusion. "Who the hell are you talking about, "we," Jamie?"

When Jamie didn't respond, Danny's gut dropped and his heart ached. "You talking about Joe?"

"Let's just drop it." Jamie conceded quickly. He knew he crossed a line and he tried to make his way out of the locker room.

But Danny wasn't allowing his baby brother to skirt out of this one. "No, no, no, no." He stepped in front of Jamie. "You brought it up for a reason. You brought it up, so we're gonna talk about it right now."

"No." Jamie attempted to sound authoritative but in truth his stomach swirled in anticipation of Danny's reaction.

And he got a reaction. "Yes!" Danny barked loudly drawing the attention of the nearby detectives.

Here went nothing. "Okay, he used to call me up at school, okay? Tell me about the job, how things were going."

Danny had no patience for the run around. "Will you get to the point?"

"You know the point, Danny." Jamie shouted back at his brother's face. "You were a hard-ass to him, just like you are to me. No matter how hard he tried, no matter how well he did, he could never get your respect." His voice wavering just slightly as he pushed around his brother's shoulder to make his exit.

Except Danny wasn't done. He reached for his kid brother's shoulders."You're not walking out on me."

The breath in Jamie's lungs disappeared as his body slammed against a bank of lockers, but Jamie had been getting his time in the gym. Plus he was a scrappy fighter. He muscled his brother the opposite way into the nearby desk. The shoving matched continued with words being spat at each other like flaming arrows. Each knowing the other's chinks in their armor.

Jackie Curatola sat at her desk cooling off from her childish interaction with the Sergeant. She'd been spending too much time around Danny to get into it about a collar. She watched as the two brothers exchanged words. She'd never seen this side of Jamie come out before and was surprised by his brazen demeanor on display.

But she wasn't surprised when she saw her partner go for his kid brother as he attempted to leave the room. Pushing back her chair hastily, she booked into the room. "Whoa, whoa, whoa, whoa, whoa, hey, wait, Danny! What the hell is going on? Danny?"

Thankfully Renzulli followed her in on her heels because she wasn't going to be able to pull these two apart. "Hey, hey, hey!"

"Get off me!" Jamie shouted at his training officer.

Jackie tried calming her wild bull of a partner "Off, off, off, Danny!"

sergeant Anthony couldn't believe his eyes as he stood toe to toe with the fired up youngest Reagan still seething. "Hey! You, let's go."

"I'm not going anywhere without my prisoner." Jamie glared daggers at his brother.

Tony was over this and he shoved Jamie's shoulder forward. "Hey, you, we're done. Do you hear me? X.O. just called. We got reassigned to Chambers Street Station."

Shaking his head, he followed his young partner out of the squad room. All eyes were on the two as they headed towards the stairs.

"What the hell?" A stunned Jackie asked as Danny righted his tie and shook out his hand.

Danny released a heavy sigh. "I'm fine."

But he was anything but fine. He'd just gotten into it with his baby brother in the squad room. His head reeled with angry thoughts. Trying to shake them from his head, he made his way towards the box where their suspect awaited them.
