AN: So this is my first ever fan fiction for Hawaii 5-0 and I'm really exited to see what you guys think of this first chapter.

Points to acknowledge:

1. In this both Steve and Danny are 34 as I am using their actors real ages, so in 1st season they were around this age.

2. Wo Fat is the same age as the actor, 51, and I made up his older brother Lee Fat who is 5 years older.

3. This is kinda a AU story so all that Wo Fat has done in this story is in revenge and doesn't follow what happens in the TV show exactly.

DISCLAIMER: I DO NOT OWN H5O IN ANY WAY.. WISH I DID BUT UNFORTUNATELY I DON'T :(

Full summary: What if when Wo Fat told Steve in the restaurant not to dig too deeply into his family's history there was a reason behind it... That reason being he didn't want Steve to know the truth...to know that he had a twin...and that his brother is closer than he thinks. For this information would be the end of him, for together, finally as the brothers separated long ago, their reunion would be destructive. But as Steve digs deeper truths are revealed, now all he has left to do is find his brother before Wo Fat does...

Chapter 1:

STEVE POV:

My brain churns with thoughts, Wo Fat's words whizzing around my head over and over like an annoying song which wouldn't get out of my head. I didn't understand what he had meant, what would I find in my family's history I wouldn't like? Most of my family was dead and gone, my mother killed in a car crash and my father murdered by Victor Hesse. My grandfather died in the Pearl harbor bombing and my grandmother a few years after that. The only family I had left now was Mary. I thought, my family had no dark secrets, but now I was starting to doubt it, how many secrets could a family hide? It just made no sense, I thought I knew my family, how can there be more secrets I did not know about? Had my Father hidden more information away from me? And how does Wo Fat know and I did not?

It was confusing and fustrating. What could my family have hidden away that was so important that Wo Fat was afraid that I would discover it, felt he had to threaten me to prevent this of happening? There was only one way to find out and that was to delve deeper into my family tree. With a nod to myself I swung my truck door open, speeding off with one thing on my mind. I would find this secret out sooner or later and nothing, not even Wo fat could stop me.

It is now two weeks later, and I am no closer to finding out the secrets, as I was after I left the restaurant. I had ransacked my house, top to bottom in search of clues, anything my father might have left behind, even dug up the old family photos from the attic, but I had found nothing other than memories of a once happy family. I had now turned to using good old Google and the HPD databases to find anything on my family's name.

I was sat in my office after a quiet day, scrolling though google searches whilst waiting for HPD to ring me back informing me whether they had found anything to do with my family.

I click on the first link that popped up when I googled my name, finding an article from last month about a raid Danny and I lead to take out a drug trafficking ring. I read over the article, smiling at the picture a bystander had managed to snap. It showed Danny, gun raised as he rushed into the house after me. I had to admit the small man looked pretty badass in the tactical kevlar he wore, the dangerous look on his face making him look fearless and combined with the fact that he held a gun pointed forwards ready to shoot, would have made any man tremble.

Flashback:

I remembered the day clearly, we had been hunting down a group of men for selling drugs and smuggling new, undeveloped and untested drugs into Hawaii. The drug killed 9 people before we raided the house the men were situated at. It was meant to be a quick and easy mission, go in arrest the men and job done, but it seems nothing goes well for the 5-0 team. Maybe Danny was right, danger did follow me.

It was seconds into the raid when shots were fired at us, bullets ricocheting from the walls narrowly missing my head. It was easy to kill the first two men and I rushed forwards to take down the next. Unfortunately for me I had not been watching my sides and it was only when I felt the force of a mans body collide into my back sending me sprawling to the floor, was when I realised the louds bangs of shots coming from my right. I swiftly stretch out my right hand, gun still in my grip and let of 3 consecutive bullets all hitting the centre of the shooters chest.

The sound of multiple shots echo through the house as the SWAT team come through the back of the house taking care of the remaining men. Chin and Kono rush to the shooter I had just downed, the oldest of the cousins kicking away the gun as the youngest bends over and checks the shooter's pulse. I sigh loudly before placing my hands on the floor and pushing up, but as in did so I finally realised the weight of the body which tackled me to the floor still lay on me. I stretch my neck, struggling to look over my shoulder and spot the familiar blonde locks which belonged to my partner.

"Danno?" I say panic building inside me as my brain thought the worst. "Danny!" I exclaim struggling to turn my body to face the man. "Danno!?" I try again sitting carefully upwards my hands already scanning over the blonde, my larger hands trailing over his head to find a reason why he was not replying, if he had hit his head and rendered unconscious.

"Get off me you animal" Danny's voice huffed sounding breathless and his hands grabbed onto mine pulling them away from the back of his head.

"You good danno?" I ask my voice worried as I hoped to dear god he was not wounded, especially if he was injured saving my reckless ass.

"I got shot when I was tackling you down-" he starts his voice gasping alittle before I cut in.

"Shot! Danno why did you not say anything you goof!" I say, voice panicking with fear as my hands struggled out of his grip, and started frantically scanning the smaller mans body for a bullet hole, a gaping wound weeping with crimson blood ready to steal away the closest thing I had to a brother.

"Well first off, you neandathal, that's my insult for you and second of all they hit my kevlar,I'm only a bit winded. Nothing I can't deal with" he answers hands stiffly waving in the air as he spoke, the old habit reassuring me slightly before my brain processed his words.

"They! What do you mean they! And winded! Danno you could have died!" I shout looking down spotting the two different holes in Danny's dress shirt, my eyes watering. The man I viewed as a brother could have died in my arm for saving my life. I could have lost the most important thing in my life, he, Mary and my Ohana the things that kept me together over the passed year. If he had not arrived in Hawaii nearly a year ago, I do not know where I would be. He kept me stable, my foundations I needed tomstay together, to prevent me from crumbling to the floor.

"Babe, calm down. One bullet hit me in the chest, the other my stomach. I'll bruise at the most! I'm more worried about the rumbling of my stomach for after all you did make me miss my lunch" he joked making me sigh in relief for if Danny was joking around and thinking of his stomach I had little to worry about. I chuckle and shake my head as I helped my wounded but not dying partner to his feet, letting him lean heavily on me as we walk towards the door we had just a few minuites before, reassured my brother in all but blood was not dying today.

End of flashback:

I was startled from my thoughts by a knock on my office door, making me jump out of my skin, nearly toppling off my seat.

"Easy there Super SEAL, its only me" I hear Danny's voice say as I look towards him, he wore a smile on his face as he walked into my office.

"Hey, Danno" I answer as I stood stretching my long limbs, stiff from sitting in a swivel chair for too long.

"I was just leaving for the night, just wondering if you need a lift?" The shorter man asked his voice warm, like when he talked to Grace.

"I'm good brah, you go I have some things to finish off. Pick me up tomorrow?" I enquire.

"Only if you let me drive for the day" he answers smirking his eyes twinkling with mirth.

" Oh come on danno!" I beg making my best puppy eyed face.

"Fine! Jeez" he relents after a few seconds.

"Your a softie you know that Danno?'" I comment smiling at the face he made.

"I am not! Anyway I need to go, see you tomorrow Steve!" he says before giving a little wave and turning away closing the door silently behind him.

I was then once more, sat in the silent abyss of my office.

I click back on the website I was looking at, before deleting my name from the search bar and typing in 'John and Doris Mcgarett' and clicking search. I wait a few seconds for the Internet to load before scrolling through what came up. Many of them were either of my mothers death, my father's death or on the heroics my dad had achieved as a HPD officer, but as I was about to click the next page a tiltle catches my eye.

The Hawaiian hero John Mcgarett to be a father of two...

I furrow my eye brows together as I click on the site in curiosity.

"The article must mean me and Mary" I thought outloud as the page loaded.

I was bought once more back to reality by a loud sound, this time the annoying shrill of my phone rather than the brotherly voice of Danny. I reach quickly into my pocket fishing out my mobile as it rang again, I pressed the green button.

"Mcgarett" I answer.

"Hey Mcgarett, its officer Keawe, you called earlier" The man on the other side says.

"Yeah, you got anything for me?" I ask desperate to known if he had found something out, anything to hint what secret had been hidden from me.

"I found records of both your parents deaths. Your grandfather and grandmothers deaths and a birth certificate for Steve Mcgarett, a unnamed brother and Mary Mcgarett. It looks as if all your dads cases are also here, from when he started to until he retired. There are case files for both of your parents murders and the casefioe into the investigation of your grandfathers death. Other than that I couldn't find much more other than background information on your family, dating back from your great-grandfather to you today. I'll send you over all the files as soon as possible" the man says.

"Thanks brah." I reply.

"My pleasure, Mcgarett. I need to go, new case just got here."

"Oright brah, thanks again" I answer.

"Bye" The voice said before the line went dead.

I was sat there letting the information sink in before my exhausted brain jolted into action, something the officer said suddenly coursing through my brain.

Brother? He said brother right? My brain frantically asked itself, trying to process the information which had been given to me. Birth certificate for Steve Mcgarett, a unnamed brother and Mary Mcgarett.. That's what he said...but I have no brothers..right?...its just me and Mary...

My brain was working overdrive. It couldn't be possible. I mean my parents wouldn't have hidden a brother from Mary and I, would they?

I tried to think, remember any mention of a brother, but none came to mind. My father never mentioned another child, just me and Mary, no other son. It must have been a mistake in the HPD records, someone must have recorded the information of the Mcgarett family wrong.

A bleeping sound from my computer alerted me of an email. My eyes fly to the screen. It was then I remembered what I had been doing while waiting for the call from HPD.

On the screen the webpage had loaded and I was staring at the bold title.

The Hawaiian hero, John Mcgarett to be a father of two baby boys.

I gasp outloud, my stomach churning as I read on.

The local hero, who recently saved a child from a burning building, has been reported to have been seen leaving a local hospital on Saturday night with his heavily pregnant wife, Doris Mcgarett. While asked yesterday at a press conference the man revealed that he would soon be the dad of two son's. It seems it is quite the exiting time for the 32 year old detective and we wish him the best of luck with his two sons, and may he stay safe in this dangerous world.

The breathe was knocked from my lungs, my eyes reading over the words again and again not believing what I was seeing.

No,no,no,no. It can't be true. I can't have a brother. It was impossible. I was the only son.

I gasp for breath, my lungs feeling as if someone had punched them as hard as they could, preventing me from drawing a proper breath. I was in a daze. Confused and hurt. How could a parent hide the fact that their children were missing a sibling?

I had always thought I was missing some thing, a part of my heart I thought finding love would fill, but it seemed I was missing my other half. The twin I never met, the brother I never had.

I felt my eyes start to water at the loss. The loss of knowing I had a brother which in all of my 34 years of living I had never met. I let a tear slip down my cheek as I mourn silently, the pain in my heart was like nothing I felt before. It wasn't as if everyday you found out you had a long lost twin brother who had been taken away years ago.

As another tear made it's way down my cheeks, my brain decided it would kick into action once more, forget all the pain, and focused on a new mission

I was going to find my brother. One way or another, I would find my other half. Now determined, my finger clicked on the next article which had my Fathers name on it.

The local hero, John Mcgarett at a all time low as he looses a son...

I wanted to scream at the screen.

Scream at theunfairness, he couldn't have died not without me knowing him, without meeting him.

I wanted to scream that it was wrong. I couldn't have lost my brother. He couldn't be gone, I would feel it wouldn't I?. Feel the pain of the loss of a sibling, the void growing dark as emptiness took it over, replacing the hope I felt of filling the space in my soul.

I let a sob leave my lips, my heart cracking in half at the thought of my brother being dead. I try to contain the massive sobs which wanted to come out but I couldn't. I struggle to regain my composure, the mere thought of my twin making my heart bleed in pain. My eyes slowly make their way to the computer screen once more in a desperate bid to find my brother was alive.

One of Hawaii's best detective's, today has suffered a massive blow, the father of two has become a father of one, as one of his sons has gone missing. On Friday night,merely a few hours after the youngest son was born, the oldest was taken from the hospital crib he and his brother slept on, the newly made parents blissfully unaware as thy rested from a tense and long labour. A nurse came in and raised the alarm when the oldest could not be found. The CCTV camera's caught a man, around 6ft, dark haired, tanned skin and of Chinese origin, dressed in a doctors scrub's, enter the private room which belonged to the Mcgarett family. He is seen leaving the hospital at approximately 8pm with the oldest son in his arms. The police have a suspect named Lee Fat under arrest who will be held with the charges of kidnapping and the murder of a doctor in order to get the scrubs he wore. However the police believe he had an accomplice in kidnapping the babe and are looking into any leads. The babe has not been found and if anyone sees a baby matching the description of blonde, blue eyed and wearing a blue baby grow, please call the police and inform them of what you have seen. This critical Information may mean life or death for an innocent baby who has yet had the time to live a happy life. We shall keep you informed on any developmens in the disappeance of the oldest Mcgarett baby.

I wanted to sob and jump in joy at the same time. To sob for I had losses a brother and to jump with joy as there was still a chance he lived. The thought fuelled me and I wanted to know more. I instantly click on the next article.

The man convicted of kidnapping John Mcgarett's son has died. The man was killed in a prison fight last week as he served his third year of his 20 to life year prison sentence for the abduction of the oldest Mcgarett son and murder of Doctor Akamai Hookano. Now three years later the babe is soon to turn a child and still remains missing and the accomplice of the kidnapping still at large. Leads led the police to the mainland before the trail of where the baby boy had gone, dried up and the case still stands as a missing persons much to the pain of the Mcgarett family. Someday we hope a reunion is seen as our hearts go out to the couple who raise the remaining twin not knowing the fate of the other.

I narrow my eyes as my tiered brain recognized the name of Lee Fat. He was the eldest brother of Wo Fat and soon it all came clear.

Wo Fat and his brother for some reason, that I would figure out, had kidnapped my brother.

Lee Fat had been caught, arrested, trialed for 20 years to life behind bars before being killed in prison three years later.

Wo Fat had looked for revenge and took it through the murders of both my parents. He now feared me finding out I had a brother, which must have meant that said brother was alive, and I understood why he was scared. For if I found my brother, I would find my other half and with that grow much stronger as I was finally whole, two missing jigsaw piece's finally joined as brothers lost long ago.

But the man had underestimated me for, now I knew, I would not stop until my brother was found, no I would rather die than live another day with this emptiness inside, the void my brother left 34 years ago when he was taken from me.

My knuckles whiten as I held the edge of my desk tightly, anger seeping from me in dangerous waves. If revenge Wo Fat wanted that is what he would get, for I was like a volcano bubbling dangerously waiting to erupt and destroy everything that got in my path as I try to find my brother.

I may not know who my twin was but I still felt the need to protect him, to find him and keep him safe from Wo Fat's once I found him, I feared I'd never let him go, to live 34 years knowing something was missing but not being able to find it was unimaginably painful.

I loosen my grip on the desk, before letting it go completely and taking the mouse again, moving it towards the next article. Just as I was clicking it my phone screeched once again.

I smile when I see Danny's face appear on the screen indicating it was him that was calling.

"Danno! Missed me already?" I ask surprised how easily I slipped into our usual banter, especially after discovering what I had minutes before. I contemplate with my self for a second, wondering if I should tell him now or to wait until I knew more. However I did not get the chance to decide before his voice sounded through my mobile.

"Steve" His voice came out as a whisper and my heart rate increased at the sound "I'm in trouble" he says, his voice hushed so quietly I nearly missed it, but my ears where trained to be sharp and I heared every word. "They got in my house" he says his voice calm but I could hear the fear behind the words.

"Who are? Danny where are you? What's going on!?" I ask much more panicked than he was, my brain was on overdrive and I shot out of my seat, rushing through my office doors catching the crash of my seat hitting the floor distantly.

"I don't know. I was asleep on the couch when I heard someone knocking on the door, so I got up walked to the door and looked through the peep hole and there was four men, I think Chinese, stood outside my door. They have guns Steve, I couldn't take them all out by myself so I grabbed my gun and locked myself in this bathroom. They knocked down my front door and there looking for me." He whispers , the words making me shake in fear. Fear that my partner was going to be found by four armed Chinese men who I guessed Wo Fat had sent.

"Danno, is there a window you can fit through? " I ask hoping to the gods above there was one.

I was rushing towards my truck as I waited for an answer, sprinting to the vehicle before throwing its doors open, shoving the keys in the ignition and smashing my foot down on the gas, the door barely shut in time as I sped off.

"Hang on...urm..yes..I'm trying to open it as quietly as I can..." He said the phone suddenly going quiet for a second and I feared he had been found "Got it" he whispered before a few grunts came through my speaker and I guessed he was climbing through the window.

His sounds of struggling to fit through the window carried on for a few seconds before loud bangs sounded through the device.

"Shit" Was all I heard before the struggling on the other side became more loud.

"Danno?!" I manage to exclaim.

"They are breaking down the door, nearly out...ah!" His voice cries out towards the end of the sentence making my heart to stop.

"Danno?!" I ask, a moan my only answer. "Danno!?" I shout my stomach sinking as I pushed my foot further down on the gas.

"Ouch. I think one of them shot me. But at least I'm out...urg..." He says making me sigh loudly in relief as his voice reassured me that he was infact still alive. "Okay..Making a run for my car in 3...ouch...2...1..." His voice says again, grunting as he ran. "Nearly there..." He trailed off just as the sound of a gunshot went off on the other side.

I hear a body hit the floor with a low glutteral moan, the sound of the mobile falling the floor echoing tauntingly through my ears, taking me away from the only way I could get to Danny.

Then all went airily silent and I heard no more.

Well that was it! Chapter 1 everybody!

Hope you all liked this, please review with your thoughts and if I should carry on or not.

Don't forget to favorite and follow :)

Until next time,
