A\N I know that Blue Bloods is still a fairly young show; therefore we still don't know a whole lot about the characters but I thought that I would take a chance and try writting a fic about Danny, Erin, Joe and Danny when they were all childern. I hope I captured thier personalities correctly. As for Joe I hope I protrayed him in the manner everybody hoped he would be in. As for thier ages I made them in the order I thought it would be after wacthing the show I wasn't sure until last weeks episode but I think I have it correctly. Anyways I hope everybody likes this first chapter.

Disclaimber: I do not own Blue Bloods or CBS

Spoilers: None

Four Shades of Blue

Six pairs of shoes belonging to three brothers echoed off the walls, and wooden floors of their house, as they chased each other in chronological order up a flight of stairs.

"Danny!" The youngest of the three wailed as his eldest brother, who stood at the top of the stairs and held his favourite book high above his short reach. "Danny this isn't civil." The six year old spoke words wise beyond his years as his brother rolled his eyes.

"Shut up Goldie Locks!" He scoffed rudely as he turned on his heel and marched straight to his room.

"Joey;" Jamie's blue eyes pleaded with his second eldest brother, "Why didn't you do anything?" He asked the hurt evident in his voice.

"I-" Eight year old Joe stumbled for words as he looked at his younger brother for an explanation. He felt Jamie's pain; he used to be subjected to his older brothers tormenting before he started to see things Danny's way. Jamie was smart, smarter than his brothers, in school at least, and had earned the name "Golden Boy" from his parents and teachers. Danny was street smart but he did poorly in academics and Jamie was helping him with his homework some nights. Joe was in the middle and had book and street smarts and he was constantly being pulled from one brother to the other one. They both had their faults Jamie was annoying and seemed know how to get what he wanted whereas Danny was bossy and aggressive and was always getting into trouble; Danny was however the oldest and was in Joe's opinion the best one to be an ally for, as that relationship had the best advantages for him. So as he stared at his baby brother Jamie in the eyes he tried to be brave and not cry as he said "Don't call me Joey!" He felt guilty however when he saw the look of betrayal and abandonment in his baby brother's eyes. " Sorry," He too turned and walked towards Danny's bedroom.

Jamie watched his best friend walk away and tried not to let tears well up in his eyes, he wanted to go after Danny and Joey and defend himself but he didn't have the courage to do so. Plumping down on the wooden floor he took off his new shoes and sat with his arms crossed.

"What did Danny do?" The sudden voice of nine year old Erin startled Jamie as his eyes met those of his older and only sister.

"He stole my book." Jamie mumbled miserably.

"Jamie I can't read your mind." Erin responded sitting down beside the youngest Reagan sibling in an effort to comfort him. "What happened?"

"Joey betrayed me;" Jamie, sniffled a response tears now slowly coming down his cheeks.

"Jamie, Joe's your brother he would never betray you we're Reagan's remember." Erin reminded him trying to smile for her brother.

"No I'm not;" Jamie cried. "I'm different; Joey, Danny, Daddy, and Grandpa they're all the same! I think I was adopted."

Erin sighed and tried to reason with her brother "Jamie I'm not like that,"

"Erin you're a girl it's different you want to be a lawyer not a cop, I have to be a cop but I'm not like that."

"Then become a lawyer, we can fight crime together, two Regan's on the streets and two on the court.' She smiled as Jamie finally smiled.

"Thanks," Jamie slowly smiled as the sound of a car pulled into the drive way "Daddy!" Jamie jumped up and flew down the stairs at the chance to be the first one of his siblings to see their father.

Erin watched her brother run out of sight before she stood and crossed her arms at the foot of the stairs glaring at Danny and Joe as they ran towards her.

"Erin;" Danny was hesitant to push his kid sister out of the way at the possibility of her falling down the flight of stairs. "Erin we haven't seen Dad in two days." He tried to reason with her.

Erin shook her head, "I move when I have Jamie's book in my hands."

"That little freak tattled?" Danny asked in distaste.

"You call him one more name and I tell Dad about your F in Spanish." Erin responded.

"Come on Dan let's use the other stairs." Joe put his hand on his older brother's shoulder.

"Cool and smart." Danny smiled proudly as he and Joe walked to the other set of stairs leading into the kitchen.

"Danny!" Erin raced after him. "Danny stop showing off! Jamie loves you and-"

"You know what Erin you've corrupted him; he's smart just like you!" The thirteen year old spat; at his younger sister as he started walking down the stairs "Joe you coming?"

"Yeah;" Joe responded as he took one look at his older sister before following Danny down the stairs.
