Sorry no Captain Swan in this One shot but, there is a lot of Killian Back story...
Using the fan theory that Davy Jones is Killian's father
Disclaimer : Sadly ONCE and Pirates of the pirates of the Caribbean do not belong to me...
Killian a young boy around ten or eleven was playing with a wooden sword with his older brother Liam who was turning fourteen soon. The bothers have played with the swords so often that they could hold a conversation in mid battle.
" So, I heard you plan on joining the Navy"! Killian said in between thrusts as he dodged his brother's wooden blade by sweeping under his brother and throwing his sword up in the air catching it before it could land on the ground.
"Yeah when I'm old enough! Why? Don't think I can do it little brother"!
"Younger brother and yes, I believe you can as I have told you before I would follow you to the ends of the world if you join then so will I"! Killian declared as he doges his brother's wooden blade.
Suddenly a tall brown haired man came out of the wood cabin forcing both of the Jones brothers to look up with admiration and awe. He came strutting towards the boys. He bent down to their level and the boys came rushing towards him with a hug forcing all three of them to fall on the ground in the dirt.
" I finally got it boys the vessel that will guide us through out the realms
a heroes journey doesn't that sound fun"? the man said with excitement in his bright green eyes.
"Yeah papa that sounds amazing"! Killian said Killian had inherited his father's love for the sea and the shape of his face. But most of his looks come from his departed mother. Helga Jones who's beauty could rival the glittering ocean floors.
Liam loved the sea as well but not as much as Killian did, Liam wanted to join the Navy because he wanted to bring honor to his family. The Jones family lived in a small hut and lived a very modest life style. He wanted to bring glory to their names.
Everything was perfect, their father got the ship and finally they could leave and live the life of a sailor at last. But, Killian noticed their father looked sheepish and nervous. Killian hoped that his father did not do something stupid.
A few hours later they were all packed and ready to go. His father looked down at his sons with sadness and shame at himself and at the thought of what he did. He could not wish the life he lead for his boys.
To be able to get the boat Davy Jones had to give his soul to the ship itself, he had no choice he was in poverty and had little opinions. He had to leave his boys. He did not want them to grow up to be pirates it is a dangerous and cruel fate.
He could not afford to take both of them he had to take one of them and leave the other on the ship. He glanced at Killian he looked to much like Helga it was to hard to look at him without thinking about his departed wife. So, he took Liam.
Meanwhile, Killian sat in the cabin of the ship sitting on the bed looking up through the hole underneath the ship trying to hear what his father was saying to the captain.
"Here give Killian this, he would want it, it was his mother's just be careful with it...its all I have left of her"..
"And what will become of the boy you can't very well leave him with Jack he is a nervous wreck around children.."
" Just give him the memory potion as well, I do not want him to track me down for this to work he can't remember Liam or me its better that way". Davy Jones said bitterly not liking leaving Killian but what else could he do?
"Don't think so Savy you see as the captain I think that Magic is not welcome here, you got my ship back from the man who robbed me and now I offer you save passage where they will not find you."
The Captain said. The man was walking strangely as if he had drank to much and the nervous twitches the man did as odd. But Killian found the man amusing. Killian was not sure if he was a bad pirate or a good one. But, he certainly knew what he was doing.
Killian did not know what to do. His papa was leaving him here, on a pirate ship. He had sold him to pirates. Liam looked troubled he looked angry at the situation he could tell.
Killian cried for two days and for a while it seemed like the rest of the crew forgot about him. But, suddenly a man stepped in it was the captain he looked nervous he rubbed the back of his neck and then sighed as he sat next to Killian.
"Alright there lad"..
Killian nodded in between sobs and said, "I'm okay, who are you"?
The man smiled and said, "Captain Jack Sparrow at your service and you must be Killian".
Killian nodded and said,"I'm scared. I heard tales of how dangerous Pirates are but, you haven't done anything to me "?
Jack sighed and said, "Listen not all Pirates are bad, some become pirates because they have no choice. Not all governments are noble and heroic some are unjust and we are the only people who are willing to stand up for those people and the corporation".
"Plus, the rum it helps numb the pain of remembering".
Killian burst into tears and said, " I wish I could forget, my father just left me. He sold me to pirates what kind of father does that... no offense".
Jack laughed and said, " I have heard people say worse so I do not mind you speaking your mind..I was raised a pirate my father was one and so was my mother".
Killian looked at him with deep thought. He did not want stay in the sleeping quarters all the time. He needed fresh air, he had gotten to go out to sea like he wanted but not in the way he wanted. His brother and father were gone. All he had was his whits and his courage.
"umm Mr. Sparrow are you in need of a deck hand I want to be useful, I hate being stuck in here all day.. I want something to do".
Jack took a moment to think. He had a lot of crew on his ship it took him a while to get the Black Pearl back, but he had her for good now, he and Davy Jones settled their differences and Will was off looking for his father Bill leaving him quiet lonely he was looking for a fresh face on his ship to ease his trouble and Killian was a clever boy surly he could be useful for something.
" Alright how about this, If you want to help that means you are part of the crew now. And you become part of our family, and we protect each other and you need to know how to fend for yourself so prepare for your sword lessons first thing in the morning."
Killian's face lit up and as he wiped away his tears with a smile that could rival the sun. Suddenly he got up from the bed and hugged Jack around the waist. Jack looked down with panic and hesitation but slowly began to return the hug.
Suddenly the ship shook and the sound of cannons firing forced Jack to put Killian down and rush towards the deck of the ship. Killian followed with excitement. He finally got to see a real ship battle!
Killian followed Jack towards the Helm of the ship and looked towards the horizon at the massive black ship. Shooting at the Black Pearl. Killian was a bit terrorized but he did not want to appear scared or Jack will make him go beneath the ship again.
"Who is that"..Killian said with amazement and a hint of fear as a man jumped down on to the ship. He had long black hair with black facial hair and bright blue eyes.
Jack frowned and said, "A very bad man Killian he is the reason Pirates are being hunted down in the first place. He is the reason stories like the one you heard exist. His name is Black Beard."
Killian looked at him with confusion and said, "Black Beard does not sound scary why would they be afraid of him for"?
"Because, he does not just interrogate his prisoners and make them walk the plank he kills them in cold blood and then drinks the blood of his victims like wine.. he is a monster". Jack said bitterly
Killian looked at Jack with shock as he looked at Black Beard as he sliced through one of the crew members throat and snapped their necks. He glanced over at Killian and laughed.
"Hello Jack I see you have taken the job of a baby sitter for Davy, Where is he nobody steals from me and gets a way with it"!
Jack raised his pistol up towards Blackbeard and said, " I was saving this shot for someone but, I will use it if you go near the boy do not harm a hair on his head or I will blow your head off"!
"Oh Please". Black Beard said arrogantly he used his sword to cut off the ropes cutting towards the beams of the mast and then swung towards Jack and kicked him to the ground.
Jack pulled out his sword and began to duel Blackbeard. Killian watched in awe at their movements he was not watching who was winning but, was watching the way they moved it was almost like a dance. The graceful footwork and the sound of their blades clashing together.
People did not know this about Killian but, he had a photographic memory, he could memorize small movements or learn new things rather easily. So, while Black Beard was fighting Jack. Killian went down below the ship and grabbed a sword.
Jack was holding his own for a quite a while, but, Black Beard was fast, and seemed to know where Jack was hitting. He could feel his movements get slower as the duel progressed.
"I will say this one more time Jack, Tell me where Davy Jones is or I will kill you"! Blackbeard roared as he ran towards Jack and raised his blade near Jack's head but Jack blocked it with his sword and grunted a bit struggling to keep his sword above his head.
Black Beard suddenly glanced over his shoulder and noticed Killian coming out from below the ship and then grinned as he kicked Jack away and said, "On second thought maybe I should go after the boy instead"!
Killian gasped as Blackbeard came charging towards him, he took one of the rum barrels and tossed it at Blackbeard's head. Blackbeard fell to the ground as the rum started exploding from the barbell.
Blackbeard glanced over at his crew and said, "Hurry and take the boy"!
Three of Black Beard's men grabbed on to Killian while Killian was laughing at how fast Black Beard fell. and then suddenly screamed and thrashed around trying to free himself from the men's grip.
"Jack help me"! Killian screamed at the top of his lungs as they jumped off the Black Pearl and back on Black Beard's ship.
"Killian"! Jack said as he tried to get to the boy but Black Beard's crew proved to be formidable foes and Jack was too weak from his fight with Blackbeard to fight back.
After a trying to fight against their grip Killian eventually gave up and cried as they dragged him to the dugon Killian had to hold his hands to his mouth to keep from throwing up his breakfast at the sight of all the dismembered bodies and the smell of rotting flesh.
"Tie him up and try to get him to talk"! Black Beard barked out as he glanced down at his men. Some of the crew watched in horror as Killian was strapped to the chair. Their are some lines even Pirates do not want to cross. But, for Black Beard their were no lines.
" Now tell me boy where is your father"? Black Beard said as he used the blade of his sword to caress his cheek. Killian glared at the man, other people might be afraid of him but Killian wasn't he took a deep breath and then spat in Black Beard's face.
"Why you little brat"! Black Beard said he raised his sword and wiped Killian's left cheek. Suddenly a small cut started bleed on his cheek. Killian winched the wound stung. Killian shifted in his chair. Black Beard still did not know that Killian had a small sword in his back pocket.
Killian glared at him and said, "I'm not afraid of you, there is nothing you can do to me that has not been done. I lost my father, and my brother...I'm alone I have no one.".
The last part had a tone of despair as the reality of what happened hit him. he might die here, this could be his very last breath. He had provoked Black Beard. But, it felt good somehow he could not imagine why.
"Why do want my father anyways he is a coward he left me on a pirate ship and sold me so he wouldn't have to deal with two children"...Killian said bitterly trying to reach for the knife but, the ropes were tight and he did not want move too much or he could be discovered.
Black Beard was no idiot the kids sob story was a nice touch but, this was not his first kidnapping, he had seen the innocent card be used millions of times. Unfortunately for them, he was immune to their tricks.
That included the boy's trick. Black Beard raised his fist and punched Killian across the face. A bruise forming on his lip. But, The boy still refused to speak.
The hit was enough to tilt the chair to the side and on to the floor and Killian was able to use his knife to break free. But, he was still trapped in the prison cell with Black Beard.
Killian looked around the cell for anything he could use as a weapon he noticed that one of the boards on the ship was loose he reached over to grab it by crawling towards the floor. But, Black Beard picked him up by the throat choking him.
" You are reckless boy, you should know better then to cross Black Beard now you are going to die here"!
"No he isn't "! A voice said as Black Beard turned around and growled at Jack who was clutching to his gut, he was bleeding on the side of his stomach.
Jack took out his pistol and shot at the lock freeing Killian from the prison before Black Beard could attack Jack picked up the plank of wood and smashed it on his head and he collapsed on the floor.
Killian looked at Jack with surprise but then the surprise melted into a relieved smile as he rushed into Jack's arms and said, "You came back".
Jack smiled and said, "Of course I did Lad, a man unwilling to fight for what he wants deserves what he gets".
Jack bent down to look at Kilian and frowned the boy was barely recognizable he had a lot of cuts and bruises on his face the one on his left cheek looked particularly troublesome.
Jack took something out of his pocket, it was a bottle of something Killian did not recognize he opened the bottle with his mouth and the sprayed it all round Killian's wound making Killian jump and winch with disgust.
"What is that"? Killian said as Jack ripped apart of Killian's clothing to wipe away the blood.
"Rum .Bloody wasted it". Jack said as he smirked at the boy with a small smile. "I got to admit you surprised me today Killian you would make one hell of a pirate".
Killian lit up and said, "You mean-"
Jack gave a small nod "Looks like its the pirates life for you lad, welcome to the Black Pearl".
Killian smiled and said, "Let's go home Jack".
Jack looked offended that Killian used his name. Killian looked at him with confusion and said, "What's wrong did I do something wrong"?
Jack frowned and said, "There should be a captain in there somewhere".
Killian laughed at how silly the man was and helped Jack with his wounds. He was a little disappointed they could not duel because he was too injured. But, he was immediately perked up when he got to steer the Black Pearl the rest of the day.
