A/N

I don't own Blue Bloods, if I did we would getting a lot more of Jamie. This chapter will include two flashbacks to make up for me not writing one last chapter. Also I have not forgotten the other Avengers, but after the first chapter I wanted to center this more around the Nat-Clint-Jamie sibling dynamic instead of focusing on the team relationship, not to worry though! The other Avengers characters will still appear throughout the story. Also, if anyone knows how to create a break lines on the mobile app please either leave that info in the comments or PM me about it, that would be a lot of help for this fic!

Because as always, Natasha Romanoff was right.

Just a few days later Jamie found himself parking his car outside of his childhood home. "You'll do great kid," Clint said, it was obvious he was eating something. "Just go in there and knock them dead!" His brother hung up the phone leaving Jamie to sit in his car in silence. Taking a deep breath he opened the driver's side door and began the long walk to his father's front door.

Danny opened the door with open arms, it was painful for Jamie to finally be back home without being back home... "Welcome!" The Commissioner shouted from the kitchen, "dinner should be out in a few minutes!" Jamie followed Danny to the dining room as if it was his first time in the house, waves of nostalgia hit him as he did so. They passed the sitting room which still had the table with the dented corner from when Joe, Danny, and Jamie were playing catch. A few more steps and Jamie saw where they used to mark how tall they got with sharpies whenever it was their birthday, then came the kitchen and memories of baking cookies and brownies with Erin flooded back to him, the smell filled his nose even though he new it wasn't actually there. Danny and his family sat on one side of the table, there was a blonde on his right and two kids at his left. On the other side sat Jamie, his older sister, and her daughter. The Commissioner and their grandfather Pops were both at the two heads of the table.

"Who's that dad?" The youngest kid asked pointing to him, Danny pulled down his arm then said,

"that's one of my work friends, Jimmy Riordan. He's here because your grandfather wants to apologise." Pops held up his hand then said,

"Before we talk shop can we say Grace?" Danny's wife nodded then they all folded there hands and prayed together, Jamie ended up joining them.

"You know prayers?" Erin asked him surprised, Jamie nodded then said,

"Yeah, once upon a time my dad would have us say them." They passed around the food, which was delicious, then his father cleared his throat,

"Jimmy, I truly am sorry for what my officer did to you in that interrogation room." Jamie just nodded then said,

"It's alright Commissioner, I get that some cops do things differently then others." Frank nodded then continued to eat his pot roast. "I'm going to use the bathroom." Danny stood up but Jamie said, "I'll find it eventually Danny." The detective sat back down while Jamie left the room.

Instead of going to the bathroom he went upstairs to see his old bedroom, surprisingly the door was unlocked. He opened it and his nose was hit with an old dusty smell, the room was kept organized, his old books were on the shelf and his bed and desk were both neat, the only evidence that someone used to live in it was the layers of dust covering the surface. Jamie walked over to the desk then sat in the chair, it was still set to his height. None of the pictures were changed either, he lifted up one in a blue frame then blew the dust off so he could look at it.

The picture itself was of the entire Reagan family, the last picture they took with everyone in it. Joe and his mother were even posing in the back. "You get lost?" Jamie almost dropped the picture in surprise.

"Oh, uh..." He said unable to think of an excuse. Frank chuckled then sat on his old bed, a dust cloud poofed up when he did so.

"It's alright Jimmy, this used to be my youngest's room." Jamie decided to play dumb for the moment, just to see if he knew anything about SHIELD.

"What was his name?" He asked, his father sighed then took out his wallet to show him a picture Jamie sent him from Harvard.

"Jamie, he went missing after the first couple weeks of his freshman year at Harvard." Suddenly a loud commotion could be heard from downstairs, the two Reagan's looked at each other then sprinted down the stairs to see what the problem was.

Four years ago...

All his hard work paid off, Jamie finally graduated and made as a level one SHIELD agent. He left the celebration part using the excuse he needed to get up early the next day, but instead of driving home he drove by his father's house. It was Sunday, and that meant everyone should be there eating family dinner. When he pulled up the car he could see the dining room through the front window, everyone was there. There was a blonde sitting near Danny Jamie didn't recognize, but his older brother seemed to be happy. Erin said something funny and the rest of the family laughed, including her daughter. His phone began to ring so he checked the caller ID before answering it, it was Clint. "Hey Blue Bird, catching those sweet dreams huh?" Jamie looked around then smirked when he saw Clint posing as a pedestrian on a walk.

"You know me, always getting a full night's sleep." Clint laughed then the conversation took a serious turn,

"Reagan, you know you can't see them anymore." Jamie sighed then ran his hand through his hair trying to figure out what he wanted to do. Finally he spoke,

"I know that Clint. It's just, I had to make sure that they're safe before I even think about getting my hands too deep into the shit pile that is currently SHIELD."

"Just in case you were worried about it I got your first assingment for you." Jamie's grin stretched across his face as he asked,

"What is it?" He could hear Clint's smile through the phone as the blonde said,

"You, Nat and I are all going to Budapest." Jamie took one last look at his old family, then pulled his car away ready to start his life with his new one.

Current time...

The second gunshots were heard Jamie drew his concealed weapon as soon as he made it to the bottom of the stairs. "Danny!" Linda, Danny's wife screamed when more gunshots went off.

"Linda, Erin, Pops, take the kids and go into the kitchen. Close the door and block it using anything you can find." Jamie instructed the blonde, she grabbed her son's and Nicky before running for cover. In the dark Jamie could make out at least seven guys, they all were armed with military grade weapons and ready to shoot on command.

"Is this really necessary?" He asked, trying to distracted the HYDRA agents from his family. The closest one to him took a shot, but he was wearing a bullet proof vest so it didn't hurt him. "Now you just made me mad." He analyized the formation pattern of the seven men then said, "HYDRA knows not to mess with me." Jamie said pulling the gun and shooting two out of seven of them in the neck.

"We are ordered to execute Jaminson Reagan, he was last seen entering this household. Prepare to die." Well, there goes my cover. Jamie thought as he picked off another HYDRA agent.

"Nice of you to give me a warning Me. Bad Guy." He said with an eye roll, out of the corner of his eye he saw Danny and his father circling around behind the HYDRA agents. Just as suddenly as before another shot rang out then Jamie felt blood start to trickle down his left shoulder. "Ouch, now I'm going to have to kill you." He said shooting the one who shot him. Danny picked off one more and his father killed the one trying to break down the kitchen door. Once the threat was over Jamie became well aware of the blood loss he was suffering from.

"Danny, call a bus!" His dad ordered Danny, the last thing Jamie saw before closing his eyes was his father's.

A few minutes after Danny and the bus brought Jimmy (Jamie?) to the hospital the red head and the blonde from before showed up in the waiting room. "Your face looks better." Danny said to Clint, the blonde nodded then said,

"Thanks. What's the status on my brother?" He asked no one in particular, Danny's father answered,

"The bullet got lodged in his shoulder, another one went through his left leg."

"Damn it." Clint swore, he held out his hand then officially introduced himself and the red head. "I'm Clint Baton, that's Natasha Romanoff." He paused as if their names should've meant something, when the Reagan's didn't say anything he continued, "we're the closest thing to family Jam - Jimmy has." The Commissioner nodded then Danny asked,

"Natasha, can I talk to you over there?" He pointed across the room far out of earshot of any pryibg family member. Natasha nodded then followed the detective to the other side.

"What do you want to ask me?" Danny must've looked surprised because she laughed then said, "profiling people is an important skill set in my job, sometimes I forget to turn it off." Danny nodded then sat in an empty chair, Natasha sat next to him.

"Who is Jimmy Riordan." She began to respond, but before she could he added, "the guys that shot him called him Jamie Reagan, but that's impossible. Jamie's been legally dead for over four years..." Natasha softened her gaze then said,

"Before I tell you, you need to understand. Jamie is an amazing asset and agent, it was his choice to continue to lose contact with his family after the first year." Danny frowned, but let her continue. "I was that read head the student reported to you all those years ago. My employer needed more people he could trust, so did Clint and I. We staged purse snatchings at multiple locations to see how well students would respond." She paused then said, "Jamie was the only one who tried to stop Clint." Scoffing Danny realized that of course Jamie would be the only one who helped the victim of a staged purse snatching. The red haird woman continued, "Jamie agreed to join us even though he was well aware of the no contact rule." Danny frowned, but still didn't say anything. "He didn't want you to be intergrated into his life, within the past year he already was moving up in our system. Jamie wanted to leave his old life behind, he wanted to forget about his family." Danny flinched then asked,

"He's alive?" Natasha nodded,

"Yeah, he is. Jimmy Riordan was his undercover name when our boss sent him to kill the guy who murdered Joe."

"I hope it's not too late..." Danny said hoping he could still get his kid brother back. Natasha smiled then spoke,

"Jamie really does miss you Danny, he always has. He just had to make a lot of hard choices these past couple of years and he didn't want to burden you with what he was going through." Danny frowned,

"But he knew I would be there for him." Natasha nodded then Danny looked across the room at his family, his father looked like he aged ten years since they got into the hospital.

All they could do now was wait...

A/N

I honestly haven't written this much in months! I'm so glad you guys are enjoying this fic so much. Budapest was Jamie's first mission with Natasha and Clint, find out what happens back then and now to Jamie in the next chapter! I hope you liked that Natasha Danny bonding moment, I figured once Danny officially met the super spys he would realize how much Jamie relied on the two over the past five years. I'm going to admit this flat out, I have no clue where the plot is going with this, but now that HYDRA's in it pretty much anything is possible.

I hope you enjoyed this chapter!
