Hey everyone! So this is my first Once Upon A Time fic so please be nice with me on this one, although constructive criticism is always welcome! Quick disclaimer, unfortunately I don't own much of this story, just any original material that is not in the show. This will be the same for every chapter so I'm just gonna do this disclaimer here and now instead of repeating myself all the time! I hope you all enjoy!

Summary:

Killian separates from Cora to find the Crocodile on his own, only to be taken to Storybrooke by the Dark Curse. He is, however, unaware of the one who has desperately searched for him for the last 300 years. How will this affect the rest of the story if Killian and Emma met before the curse was broken? And what will happen when Killian's past finally catches up to him. I plan on this being quite a long fic with a very different OC. It will primarily be Captain Swan but there will be lots of other ships as well as differnts arcs and adventures, although it will be relatively canon throughout season 1, 2 and 3a but it will change at 3b because of my OC. Don't worry though, I plan on bringing her in much earlier than 3b!

Prologue:

Jacquelyn heard her brothers trudging up the stairs, finally home from working all night at the docks. She pulled her blanket up to her chin and squeezed her eyes shut, pretending that she had been asleep all night, before her brothers peered behind the curtain to check on her. A knowing look was shared between the two eldest members of the Jones family.

"I don't know, Liam," the younger brother began, his sea blue eyes holding a mischievous glint. "Our dear sister seems so tired, it would be a pity to wake her."

"My thoughts exactly, Killian, we should leave her to sleep," the older boy responded, barely containing the smirk that was spreading across his face.

"But you promised you would wake me up so I could see the birds in the town square," the young 7-year-old cried, her ruse of restful sleep forgotten as she sat up in bed.

"Ah, but how can we make good on our promise if there's no need to wake you up," Killian said, raising his eyebrow at his younger sibling. This obviously didn't sit well with Jacquelyn, as she petulantly stuck her tongue out at her brother, causing Killian to let out a small chuckle.

"Now, now, you two. That's enough teasing for this morning," Liam chastised, even though he himself was resisting the urge to smile at his younger siblings' antics.

"You will still let me stay up to watch the birds with you though, won't you?" Jacquelyn said sheepishly. She had meant for it to sound sweet and innocent – she knew that she had her brothers wrapped around her little finger – but her tone was laced with worry that they would make her go back to bed.

"Well…" Killian began, with a sly look to his brother.

"I don't suppose it would hurt just this once," Liam concluded, returning Killian's glance.

Jacquelyn beamed at her older brothers and jumped out bed, her too-big nightdress trailing on the floor behind her as she rushed to her window. Liam and Killian joined her at her window and pushed the wooden shutters open for her, the light of dawn streaming into the room. Killian lifted his sister up so that she could get a better view of the giant oak tree that stood in the middle of the cobbled town square.

Liam ran a hand over his face. He was exhausted; both brothers were. They really needed as much rest as possible before they started another long shift on the docks, and it was foolish to think that they could forego whatever little sleep they could get. But the smile on Jacquelyn's face when she saw blue tits and the finches flapping around the leaves of the oak tree, the way it lit up her features, both brothers knew that it was worth sacrificing some of their energy to see their little sister so happy.

Suddenly, Jacquelyn let out a huge yawn. "I do love watching the sparrows and the other birds in the morning, but must they wake up so early?" she complained.

"It's just in their nature sweetheart, especially the sparrows," Liam replied.

"But why is it in their nature, Liam?" she asked him sleepily, rubbing her eyes.

Liam and Killian shared a look over their sister's head that said exactly what they thought. Stubborn lass.

"It's because," Killian began, grabbing his sister's attention. "The sparrows are remarkable creatures. No matter what kind of day they have had previously, whether they caught they best worms to eat" he continued, tickling his younger sister and making her giggle hysterically, "or were almost eaten by a hawk, sparrows always have hope for a new day. It's this extraordinary hope that motivates them to wake up bright and early, to see as much of the new day as they possibly can." Killian stared down into his little sister's face and saw an awed expression etched into her features at her big brother's explanation.

That is, until it was replaced by a confused frown. "But why are they so hopeful, Killian?"

The brothers shared an exasperated sigh, which turned into a rueful smile. "I think it's high time you went back to sleep, young lady, that's enough questions for one day," Killian said, switching Jacquelyn's position from on his hip to in front of him by placing his other arm under the backs of her knees. He carried her back to her bed while Liam unfolded her blanket so that she could be tucked in again.

"But I'm not sleepy," Jacquelyn said through a yawn.

"Of course you're not," Liam said sarcastically, already seeing her eyelids drooping. He leaned forward and pressed a kiss to her forehead. "Goodnight, Jacquelyn."

Killian repeated his brother's actions, and got up to follow him to their room, but was stopped before he disappeared behind Jacquelyn's curtain.

"Killian?" Jacquelyn asked quietly.

"Yes, Jay-Jay?" he answered her.

"Will you sing to me so that I can go to sleep?" she asked him with her big pleading eyes.

Killian fixed her with a hard stare, but it was no use; he eventually caved in and went to sit down on the side of her bed.

"Alright, but only until you fall asleep," he said. Jacquelyn grinned, knowing full well she was getting her own way, and closed her eyes as Killian began to sing the familiar lullaby.

"Upon one summer's morning,

I carelessly did stray,

Down by the Walls of Wapping,

Where I met a sailor gay.

"Conversing with a young lass,

Who seemed to be in pain,

Saying, 'William, when you go I fear you'll never return again.

"My heart is pierced by Cupid,

I disdain all glittering gold,

There is nothing can console me.

But my jolly sailor bold…"

Killian barely finished the first chorus before Jacquelyn was asleep, her breathing becoming deeper and more even. Killian smiled fondly down at his younger sister, and brushed a lock of her raven hair away from her face. "Goodnight, Jack," and he kissed her forehead once more before walked out of her room to collapse into his own bed.

Deputy Killian Jones woke up from his strange dream to the sound of his roommate, Graham, knocking on his bedroom door and telling him to wake up or they would be late for work. Pushing the unusual dream to the back of his mind, he sat up in bed and ran a hand through his messy, black hair. Welcome to another day Storybrooke.
