A/N: This is a fluffy drabble that was prompted FOREVER ago by a lovely reader. They wanted the song "Lighthouse' by Collabro and the story to include a Lieutenant Duckling Reunion fic. It has been so long since I've gotten to write something like that, and I have really missed it, so here is my attempt at some cuteness for you all. Thanks for reading, and thanks so much to the awesome reader who suggested this!

Please let him be safe. Please let him come home. Please let him return to me.

The silent prayers were ones that Princess Emma had begged for more times than she could count. Over the past year, while Killian was out at sea, serving in the royal navy, Emma had been beside herself with worry. It was bad enough to be separated from the man she loved, but to know that he could be in danger all this time pained her heart in shades of sadness she'd never be able to vocalize.

If she had her way in this scenario, Emma would be down at the docks, watching the horizon for any sign of his ship in port. No, forget that idea, she'd be on the ship with him, facing whatever harrowing adventures the high seas might call for without a drop of fear. When she was with Killian, nothing could touch her. The magic they shared was a barrier against anything bad, a fortifying force that protected them both, and Emma felt steadier and at peace. But alas, her destiny was written already, and it held no space for seafaring voyages or long treks on the open ocean.

As the one-day heir of the realm, Emma was expected to put on a brave face and attend to her duties. The people looked to her and her family for leadership and guidance. They all played a part in the health of this kingdom, and her birthright was to inherit all of this someday. At some point in the not too distant future, when her mother and father were ready to step aside, it would be Emma who took the throne, but all the grandeur and the power meant nothing to her, not without Killian to share it with.

Every spare moment she thought of him, and imagined what it would be like someday, when this was all behind them. This was his last deployment under the careful watch of his elder brother Liam, and prior to his going, he'd already received her parent's blessing to marry her, though not before asking Emma for her hand herself. She'd accepted in a heartbeat, failing to let him even finish the romantic question when she understood his intent. She was desperate to be his in every way, and remembering the smile he'd bestowed on her and the kisses that they shared when she'd agreed, it was obvious that Killian felt the same.

Almost a whole year had passed since that miraculous night, and not long after he was sent away, sailing for the edge of the known world to see what lay beyond. It terrified her to think of what danger may lurk in what was unknown, but Killian reassured her that it would all be fine. He and Liam knew what must be done. They understood the sea and their mission, and Killian swore to find his way back to her just as he had so many times before…

"I just wish that you didn't have to go," she'd said, unable to hide her tears in the early morning hours before his ship set sail. They'd run off together to the guest house in the garden, a special spot of theirs since they met when they were younger. For years it had been their hideaway. Killian called it their sanctuary, and Emma always thought that was an apt description.

"Believe me, love, if there were any way around this, I would see the course. You know I'd give anything to be here making you mine as soon as may be. But my brother needs me, and your father has been clear. We need these alliances for the good of the kingdom, and the safety of the people, you most importantly."

"I know," Emma agreed, understanding more than most how precious their alliances were with the kingdoms of all realms. This voyage, though long and arduous, would protect them for years to come, and was the last request of Killian's brother Liam before Killian exited the navy. "You just…"

"I just what, love?" he asked, cupping the side of her cheek and watching her with those beautiful blue eyes of his that always made her dizzy. They were so focused in on her, as if the universe began and ended with what she was about to say. In a world where she was important but never felt truly seen, she'd grown addicted to such attentions. Killian truly knew her and still loved her, and she was more herself with him than with anyone she'd ever met. She leaned into his touch and closed her eyes, breathing in the scent of him and savoring the warmth and electricity that came when he was close.

"You just made me love you so much, that letting you go feels like losing part of myself."

The murmured curse he let loose before devouring her lips made Emma shiver with delight, but she was hardly cold. His touch was like a fire, sizzling through her and marking her as his, just as much as she was marking him as hers. She didn't know how long they stayed like that, wrapped up in each other, but it felt mere seconds later when they pulled apart. The brightness of the room and the daylight that was breaking signaled much more time had passed than seconds, but it wasn't enough. No amount of time together ever would be.

"There's nothing in this world or any other capable of keeping me from you, Emma. My love for you is constant. Not just for this life, but every one from here to always. Have faith in me, my love, because I promise I will be home to you as soon as I am able."

Though the words were whispered so long ago, Emma still felt them wash against her skin as the sun began to sink over the tree line. Out here, in the back woods of the palace, she was totally alone, but if she couldn't be with Killian, that solitude was all she could accept. She closed her eyes and allowed herself to fantasize that he was here. Autumn's chill was back once more. The year was up, and so too should his mission be. In a perfect world she'd hear the gentle crunch of footsteps and catch the subtle scent of ocean waves. The footsteps would approach with precision and determination until the moment just before he reached her where heat flared through her system. She fended off tears at how good her imagination was becoming, and then she felt him, the undeniable press of his body on hers that was so much more vivid than any daydream ever could be. Her eyes popped open and her heart took flight.

"Emma," he said, nuzzling into her neck as he held her tight and the sound that came from her chest was one of desperation and relief. "Gods how I've missed you, love."

"You came back," she said, spinning in his hold and seeing that this was truly real. Killian was here and alive. He was somehow even more gorgeous than when he'd left, and he was looking at her with even more affection and love than he'd had before. Tall dark and handsome did no justice to all he was. He was perfection, and he was all hers.

"With a light like yours to return to, there was no other option, love. Trust and believe in that."

He whispered the words of affirmation as her hand came over his chest. She felt the racing of his heart, and she knew, without his admitting it all that things had been the same for her him as they had for her. She may have been here, and he may have physically been worlds away, but her heart could not reside in a space without him. Now they were together again, and she was whole, happy, and unwilling to ever let him go.

Pulling him in by the collar of his navy coat, Emma almost wept when their lips met after so long a separation. His taste was just the same, his arms, holding her close, the warmest and most soothing home she'd ever known. She was safe here and hopeful, finally believing that the worst was behind them. From here on out things would be different. She and Killian would be together, and there'd never be cause for such sad partings ever again.

"I thought for certain that the love we shared before was as big as it could be…" he murmured, running his hands through her flowing hair and smiling at her, as if he was trying to convince himself that this wasn't all a beautiful dream they'd both soon wake up from. "How wrong I was in such a thought. This love grows deeper every day. It can't be quantified. It just…"

"It just is," Emma echoed, and he agreed, kissing her again and grounding her in a happiness that had been missing for twelve long months. Only when they were breathless, did they break apart, but even then his forehead rested against hers, his arms surrounding her, giving them space to breathe each other in and surrender to their feelings.

"I've brought you something, Emma," he finally said, and she could see the pride in his eyes at the mention of this gift. "It's something I hope you'll find worthy of a woman like you."

Emma knew she'd cherish any parcel from her sailor, but the preemptive affirmations died on her lips as he pulled out a small velvet pouch. Inside the compartment was a ring with a band of white gold, and a green blue gem unlike any she'd ever seen. In the royal vaults there were many treasures belonging to her family, but none that looked like this. It was a sapphire, but colored in such a vibrant aqua hue it didn't look like any stone she'd seen before. Yet it wasn't the first time she'd seen this iridescent shade. In fact, it was one that always seemed to find the two of them some way or another.

"Killian, it's gorgeous," she said in awe, amazed at how much it looked like the lightest flecks of color in his piercing blue gaze. She knew that in her own green eyes there were flecks of this tone too, a shared sample of their souls, indistinguishable and utterly spectacular. "But you didn't need to bring me anything. All I need is you, you know that."

"I do, love. Believe me, a man doesn't forget such miracles when he's as blessed as I am. But you are to be my wife, and after searching for some time, I finally found the ring I know was meant for you."

With gentle ease, he took her hand in his and placed the ring on her finger. It was a perfect fit, and matched the modest white gold of the band he'd given her in promise before he left. Emma knew he'd had the choice of any ring in the castle for his proposal, but he was determined to find something special just for her. She didn't need anything more than the wedding that would come, but when he shared the origin of this particular gem, she felt its significance.

"I found this treasure at a time of great pain. I missed you so dearly, that even the sea could offer no distraction. Twelve weeks into a twelve-month journey and I was homesick, as I've never been before. I walked along the beach in port and found this in a tide pool, underneath a rising moon. Liam gave most of the crew some leave for the first time in ages, but there was nothing that I wanted when I knew you were waiting for me here.

"My brother insisted I get off the boat, despite my attempt at protest, and so I wandered for a while, thinking only of you. Of your beauty and your brilliance and the future you deserve, the one I will do anything to give you. The waves in that water are notoriously unruly and sporadic. They rage along the coast and filter into tide pools unlike our shores here, but the locals claim that the sea bring treasures and tricks alike from far off places. Needless to say I didn't care about these stories. All I cared about was you. I was thinking that maybe I should come home, even though the mission was not over, and then I found this, glistening in the water just below."

Emma looked down at the stone and their hands intertwined. She imagined each point of his memory, feeling it so surely, it was like she had been there too. It helped in easing the pain of separation, and she settled in the fact that soon their being parted would be just a distant remembrance, never to be repeated.

"The first time I held you in my arms for a dance, you were dressed in a gown of this shade. I'll never forget that night as long as I live."

"Neither will I," Emma agreed, recalling her public debut. She was a girl of sixteen and Killian was the brother of one of her father's most trusted Captains, a whole year older than her but already in her eyes so much more mature. Now, so much time had passed, but when he smiled at her the same boyish charm was ever present, and she fell under his spell, stepping into his arms as she would to share a dance. Out there, in the setting sun he held her close, guiding her though there was no music, and she tried not to cry the joyful tears that threatened to spill as he twirled her, eliciting a laugh and making her feel lighter than air.

"Finding this felt like a sign, that even we were parted, we would always be together. I carried it every moment since, knowing someday it would end up here, with you."

"And now it's here, and so are you," she whispered, stealing another kiss from him and halting their dance. He was the sweetest man alive, of that she had no doubt, but suddenly that sweetness was not what she needed. What she needed was love, the love that only they shared, made real in a stolen, private moment.

Reading her mind and her wants with precision, Killian pivoted from dancing to sweeping her up into his arms. She laughed aloud at the motion but didn't pull back far. Instead she clung to him as he strolled through the back way. A few minutes later, when they arrived back at the garden house she was in no way surprised. She hadn't been out here since his leaving, but it was just as she remembered, and immediately her sense of inner peace solidified. This was everything she'd wanted and more.

The kiss he pressed on her once they were shut away inside was filled with heat and desire, and soon kisses devolved into so much more, a merging of two people who had missed each other fiercely and we were intent on tying themselves together once again. It was perfect, hard-fought reunion, and Emma would cherish the memory always. But perhaps no part was as special as the glow that came between them when she was wrapped up in his arms hours later, safe and happy as the dawn of a new morning began to break. The world was not bright enough to have created such vibrancy, that was all thanks to them and their true love. As a product of two soul mates, Emma had inherited a bit of magic herself, but that magic was always the strongest in the arms of her Killian.

"Gods above, Emma, you are my light, my truth, my home," he murmured, his words placed between the lightest kisses that sent thrills of pleasure dancing across her skin. "I'll love you forever, I give you my word."

"Good," she replied, silently affirming that she felt the same with a gentle kiss before finally giving in to the tiredness of her body. And luckily for both of them, the sweet dreams that came of their reunion were nothing compared to the joy of their life together. For they had found something better than wishes – a love so real it would live forever, and a bond so sure it would always lead them home.

Where ever I am

Where ever I go

Whatever happens, this year I know

That you'll be with me to the end

When the cold sets in

Like you told me all those years ago

You hold my hand

Where ever I lay

And you guide me through come what may

Bring the silence through the noise

I still hear your voice

I remember what I heard you say

I'll be your lighthouse

Shining bright from dusk till dawn

I'll sing a song aloud

So you'll hear a voice you know

You'll find that somehow

Where ever you are, where ever I am

Is home

Whenever I feel

I'm all by myself

And every word is a cry for help

I just think of you and then

I'm safe again

I feel you close though you're somewhere else

I'll be your lighthouse

Shining bright from dusk till dawn

I'll sing a song aloud

So you'll hear a voice you know

You'll find that somehow

Where ever you are, where ever I am

Is home

Do you remember

What we used to say?

I'll be your lighthouse

Shining bright from dusk till dawn

I'll sing a song aloud

So you'll hear a voice you know

You'll find that somehow

Where ever you are, where ever I am

Is home

I'll be your lighthouse

Shining bright from dusk till dawn

I'll sing a song aloud

So you'll hear a voice you know

You'll find that somehow

Where ever you are, where ever I am

Is home

Where ever you are, where ever I am

Is home

Post-Note: Wow, so first and foremost, if the person who requested this even still reads my fics (because it has literally been something like 4 years since they asked for this), I hope that you enjoyed the chapter. I am so sorry for making you wait so long, but I am also so grateful for your lovely prompt. What happiness this fic created for me as I wrote it. I hope you all get to share in that too as you read the story. I'm also shocked at how close I am getting to 200 chapters of the mixtape. I can't tell if it is something that I should put on hold, or make a volume two perhaps, but in the meantime, thanks so much to all of you for reading, for commenting, and sending me amazing songs to include. It has meant the world to have your support, and I hope you'll continue to join me on this slow but steady journey in cute CS oneshots!
