I hadn't planned on expanding this anymore, but I received an idea that was too good to pass up. This, however, WILL BE the last installment of My Happy Ending. So, here it is. I hope y'all enjoy! :)

Killian had just pulled the Jolly Roger into the docks. He thought he'd take her out and make sure she was ship-shape before he took Emma and Alena out sailing tomorrow.

Just as he had secured the rigging and was stepping foot on the dock, he saw something out of the corner of his eye. He turned his attention back toward the water and smiled at the sight. The Nautilus was coming to the surface.

A couple of minutes later, Nemo and William were stepping foot on the dock. They then made their way toward Killian.

The dark-haired man asked, "What brings you two back to Storybrooke?"

"Well, after all our travels, we wanted to stop by for a visit. We've been thinking about you," Nemo explained.

"Well, it's wonderful to see both of you," Killian spoke as he smiled at Nemo and his brother.

"And you, brother," William responded as he returned Killian's smile.

"Is it true that Storybrooke has been peaceful since the defeat of Gideon?" Nemo then asked.

Killian nodded before he elaborated, "Though it still feels strange at times, we have been villain-free for over six years now."

"That's great news," Nemo told him, and Killian nodded in response.

William then questioned, "And how is Emma?" with a smile.

Killian smiled back before he answered, "She is wonderful. We were married shortly after the defeat of Gideon, and we have…" He paused for a moment as an idea struck him. He then continued, "And we have a surprise for you."

Both Nemo and William looked at the pirate curiously before William asked, "And what kind of surprise would that be, brother?"

"One that I'm sure you two will be thrilled by," Killian told them. He then continued, "Allow me to call my lovely wife, so that you two can come by the house for a proper visit."

Both Nemo and William nodded before Killian took out his cell phone.

As soon as Emma picked up, she greeted, "Hey, Killian. Is your ship all ready for our trip tomorrow?"

"Aye, love," Killian began. He then continued, "I called you because Nemo and William came by for a visit."

"That's great, Killian," Emma cheerfully responded.

Killian then spoke, "I wanted to surprise them with the reason for our happy ending, love."

She instantly understood and replied, "Sounds like a plan. I'll tell her right away."

"Thanks, Swan. See you in a bit," Killian told her. "Bye, Killian," Emma told him before she hung up the phone.

Killian then turned his attention to William and Nemo and announced, "Alright, mates, let's get going." Both men nodded in response.

When Emma had hung up the phone, Alena immediately asked, "Was that Daddy?"

The blonde nodded and smiled as she answered her daughter, "Yes, it was. And he has a surprise for you."

Alena's blue eyes lit up with excitement as she exclaimed, "A surprise!"

"That's right, kid," Emma began as she ruffled her daughter's black curls. She then continued, "I need you to go to your room to wait on Daddy, okay?"

"Okay, Mommy," Alena excitedly spoke.

Emma smiled at her before she told her little girl, "Why don't you go ahead and walk upstai…" The blonde trailed off as Alena poofed herself to her room.

"Or just use magic," Emma spoke before she shook her head.

A couple of minutes later, she heard the front door opening. She smiled when she saw her husband, followed by Nemo and William.

Killian greeted his wife with a kiss on the cheek. He then asked, "Where's the surprise?" "Upstairs," Emma replied with a grin.

Killian nodded before he headed upstairs, leaving the blonde to greet their visitors.

"Emma, it's so lovely to see you," the captain spoke.

"And you," she responded with a smile before she hugged him. She hugged William as well.

As she pulled away from the younger Jones, he stated, "I'm curious about this surprise that my brother told us about."

"Well, you won't be waiting much longer," Emma assured him and Nemo.

Upstairs, Killian had just walked into his daughter's room. Alena exclaimed, "Daddy! I'm so excited about the surprise!"

Killian chuckled before he told her, "I can see that, love," as she stroked her hair.

Alena then asked, "Can we go now, Daddy?"

"Aye, love," he replied before he took her small hand in his. They then made their way out of Alena's room and down the stairs.

Emma, Nemo, and William were still talking when Killian and Alena arrived in the living room.

The dark-haired man then announced, "William, Nemo, I would like you to meet our daughter," with a bright smile.

Both Nemo and William smiled at the little girl before she ran toward them. She shouted, "I'm Alena!" She then wrapped both of them in a crushing hug.

"Well, it's lovely to meet you, Alena. I'm Nemo," the captain spoke.

"And that makes me your Uncle William," the younger Jones added.

Alena nodded before she smiled brightly at the two men. She then ran back over to her father.

She tugged on his hook and spoke, "Daddy, I have to ask you something," in a loud whisper.

Killian bent down on his daughter's level and asked, "Yes, love?" Alena whispered something in his ear, and he grinned at her words.

He then told her, "Why don't you ask him, love? I'm sure he'll say yes."

The little girl nodded before she ran back to Nemo. She looked up at him with big blue eyes and asked, "Will you be my uncle, too?"

The captain smiled at Alena as he answered, "I'd love to be your Uncle Nemo."

"Yay!" Alena cheered before he hugged Nemo once more. She then announced, "Uncle Nemo! Uncle William! I got to show you my magic!"

"Magic?" William and Nemo asked a bit confusedly.

"Yes – as a product of true love, Alena possesses magic," Killian explained.

"But she's only supposed to use it for special reasons," Emma reminded her daughter.

"This is special, Mommy," Alena stubbornly pointed out. Emma rolled her eyes while her husband, brother-in-law, and Nemo grinned.

Killian then spoke, "Come on, love. I think we can let it slide this time."

Emma thought for a moment before she sighed and resigned, "Alright, kid, you can show your uncles your magic."

The little girl cheered before Emma told her, "But we're going outside."

"Okay, Mommy," Alena responded. She then grabbed William and Nemo's hands and practically dragged them to the backyard.

When they all arrived, the little girl ran to the middle of the yard, her black curls bouncing behind her.

She then turned to face her family and waved her hand, making a butterfly appear. It flew over and landed on Nemo's arm.

The captain smiled as he told her, "That's quite impressive, Alena." She smiled brightly in response.

A moment later, she waved her hand once more, and a swarm of butterflies then appeared in the yard. It was as though Alena had conjured up every species of the winged creatures, and to be honest, she probably did.

A rainbow of colors was flying around, and one little girl was clearly proud of her work. She was chasing them all over the yard and was giggling the whole time.

Emma and Killian were both shaking their heads while Nemo and William were fighting grins. William then spoke, "She's fond of using magic, isn't she?"

"Well, Emma believes that she's a little too fond, and I'm inclined to agree with her," Killian admitted.

The blonde then added, "It's not that we aren't proud of her abilities. We think it's wonderful that she has magic. But we don't want her to become reliant on it, and we want to make sure she uses it in the right way."

Nemo then added, "It's completely understandable. Magic can be a very dangerous weapon if one isn't careful."

Emma and Killian nodded in agreement before the blonde went to go address their daughter. She told Alena, "Alright, kid, I think it's time to send these butterflies on their way."

"But Mommy," the little girl began to protest. "Alena," Emma sternly spoke. The dark-haired girl nodded before she waved her hand, and all of the butterflies disappeared.

A moment later, Alena had another idea, and she asked, "Uncle William? Uncle Nemo? Do you want to play pirates with me?" practically bursting with excitement.

"Pirates, huh?" William asked, and he couldn't help but grin at his brother.

Killian scratched behind his ear as he answered, "Uh, yes. The lass is her father's daughter." He then told Alena, "Love, I doubt that playing pirates is your uncles' idea of fun."

"Nonsense, Killian. I think it's a chance for us to get to know your lovely little girl," Nemo spoke with a smile, and William nodded in agreement.

Emma and Killian nodded and mouthed "thank you" before Alena cheered and went to grab Nemo and William's hands.

An hour later, Alena had dragged her parents into her game. The black-haired little girl was playing the role of her father, while everyone else was playing the role of the various villains that he had faced during his time in Storybrooke. As she ran around the backyard, her weapons were a plastic hook and sword (although if she had her way and would have thought of it, she would be donning her father's hook and would have conjured a real sword).

Alena then sat down on the grass, clearly tired from the running. Killian grinned as he went over to her and pushed the curls from her forehead. He then told her, "Alright, love, even heroes need to rest."

The little girl nodded in response before she asked, "Daddy, will you give me a piggy back ride inside?"

"Of course I will, Alena," Killian responded as he smiled at her. He then got down on his knees, and his daughter then climbed on his back, sword and hook in her hand. They then began making their way inside.

Emma smiled at the sight before she turned her attention to Nemo and William, who were smiling as well. She then asked them, "How about I make us all some fresh lemonade?"

"That sounds great, Emma," William responded. The blonde nodded before she went inside, followed by their guests.

Emma found her daughter sound asleep as she sat beside Killian on the couch. He was wearing a smile as he softly stroked her black curls.

She bent down in front of her husband and Alena before she quietly spoke, "Looks like someone needed a nap."

"Aye. Though she stubbornly protests, like someone else I know," Killian began with a teasing grin. Emma rolled her eyes before he continued, "She still needs her daily nap, love."

Emma nodded before she asked, "Are you going to take her to her room?" "Aye, Swan," Killian answered before he got up and carefully took his daughter in his arms.

"When you come down, I'll have some lemonade for us all," Emma told him. The pirate nodded in response before he headed upstairs.

He went into Alena's room and carefully pulled back the covers. He then gently laid her down before he pulled the covers up to her chin. He placed her stuffed swan beside her as he kissed her forehead.

"Sleep soundly, my little love," Killian whispered before he left her room and walked back downstairs.

When he arrived, he saw Emma, Nemo, and William sitting at the round dining room table. He sat down beside his wife before she handed him a glass of lemonade.

"Thank you, Swan," Killian told her before he planted a kiss on the side of her head. Emma nodded and smiled in response.

Nemo then spoke, "I want to congratulate you both on a happy marriage and a beautiful family. I'm really proud of you Killian."

"I am too, brother. You're a great father to Alena," William added with a smile.

Killian, who still wasn't the most comfortable being praised, scratched behind his ear before he spoke, "Thank you, both. I can't tell you how much it means to me to hear you two say that."

"You more than deserve it, Killian," Nemo reminded him.

The dark-haired man offered a small smile before he honestly told the captain, "I owe some of that to you, Nemo."

Nemo looked at him curiously as he asked, "What do you mean?"

"Well, you were the one who told me I needed love and family in my life all those years ago, and you were right, even if I couldn't see it at time," Killian honestly began. He then turned his attention to his brother and continued, "And it's also because of you, Nemo, that I was reunited with my brother, and he was able to forgive me for what I did to our father all those years ago."

"That was a long time ago, Killian," William pointed out.

"I know it is, and I've long forgiven myself, but I still thought you and Nemo deserved some credit," Killian replied.

Both men smiled before Emma added, "Well, I still think you don't give yourself enough credit, Killian. They may have played a part in your redemption, but you are the one who chose to change. And now you have me, our beautiful daughter, and our family to show for it."

Killian smiled as he spoke, "And that makes me the luckiest and the happiest pirate in all of the realms."

Emma smiled back before she kissed him on the cheek. Nemo then spoke, "I say we toast – to family."

Everyone smiled before they nodded. They then clinked their glasses of lemonade before they all took a sip.

A moment later, they heard footsteps coming down the stairs. William observed, "She couldn't have slept for more than ten minutes."

"Well, aside from the fact that she doesn't like taking naps, she's also probably too excited because you and Nemo are here," Emma responded.

The dark-haired little girl then appeared in the kitchen, and she instantly ran over to Nemo. She then made a move to climb in his lap. The captain smiled as he picked her up and sat her down.

Alena then asked, "Daddy said that you and Uncle William ride in a submarine all the time – is it fun?"

Nemo smiled as he answered, "William and I have sailed together for many years, and we do enjoy it."

Alena smiled before she announced, "I want to know about all of the places you been to, Uncle Nemo!"

Nemo couldn't help but chuckle before he told her, "That would take quite a lot of time, Alena."

The little girl looked disappointed, but the captain added, "But let me tell you about a place that I'm sure you'd enjoy."

Alena' blue eyes lit up as she asked, "What place is that, Uncle Nemo?"

"A beautiful place home to mermaids, mermen, and every sea creature imaginable. The underwater kingdom of Atlantica," Nemo answered.

Alena gasped in excitement before she exclaimed, "I love mermaids! Did you see Ariel?"

"Love, you know that Ariel lives on land now with Prince Eric," Killian explained.

"Oh," the little girl simply responded. She then asked, "Is it as pretty as the movie?"

"It's even more beautiful. And it's absolutely magical," William told her with a smile. Alena smiled brightly at him in response.

She then asked another, yet completely unrelated question, "My daddy's ship is the Jolly Roger – does your submarine have a name?"

Nemo smiled as he answered, "It does. It's called the Nautilus."

The curious little girl then turned her attention to William and asked, "Aren't you Uncle Nemo's first mate?"

William smiled as he answered, "I am." He then asked her, "And are you Daddy's first mate?"

Alena's blue eyes lit up as she excitedly nodded. She then told him, "I help him sail the ship! He says I'm the best!"

Both William and Nemo smiled, as well as her parents. The captain then spoke, "Well, I'm confident that you are, Alena."

Alena smiled brightly once more in response. She then spoke, "Tell me more about your adventures!" Nemo and William smiled before the captain launched into more stories.

Over the next hour, Alena listened intently to Nemo and William, including their time with Killian. Though it may not have been the most pleasant, it all worked out in the end.

The captain then spoke, "Well, Emma, Killian, and Alena, as much as William and I have enjoyed our time, we must be getting back to sea."

"Aww, do you have to?" Alena complained as she looked up at Nemo. "I'm afraid so, Alena," he responded.

The little girl's blue eyes filled with disappointment, but William quickly told her, "Hey, I promise we'll come visit again."

"Yay!" Alena cheered, and Emma added, "I think we'd all love that." Both men nodded in response.

Killian then spoke, "Shall we go to the docks and see you off?"

"I think that's a great idea, Killian," Nemo responded. Killian smiled and nodded in response.

Alena then piped up, "Will you give me a piggy back ride, Uncle William?"

"You really don't have to, brother," Killian added.

"Well, she is my favorite niece," William spoke with a grin before he tickled Alena's side, making her giggle.

"Technically, she's your only niece," the pirate pointed out, and Emma hit his arm. Nemo and William couldn't help but chuckle.

The captain then announced, "Alright, let's get going so that my first mate and I can make good time."

Everyone nodded in response before William scooped up Alena and put her on his back and headed for the door, followed by Nemo, Emma, and Killian.

As they began heading toward the docks, Alena asked, "Am I really your only niece, Uncle William?"

Emma shot a stern look at Killian, who simply shrugged. Nemo and William grinned before the younger Jones answered, "Yes, Alena, you are."

"Why?" the dark-haired girl questioned.

"Well, your daddy is my only brother besides Liam," William explained. He then continued, "And your Uncle Liam didn't have any little girls."

"That's 'cause he took care of Daddy," Alena stated. "That's right, love," Killian told her as he stroked her black curls.

Alena then asked, "Are you glad that my daddy found you so you could be brothers?"

"Kid, where are these questions coming from?" Emma asked her curious daughter.

" 'Cause he's daddy's family, and I want to know," Alena announced. Her mother couldn't help but roll her eyes.

William then assured the blonde, "It's perfectly alright." He then addressed the little girl on his back, "I am very glad that Killian found me. Now I have him, your mommy, and you as my family."

Alena smiled brightly before she kissed her uncle's cheek, and he smiled at the gesture.

They then arrived at the docks and walked over to where the Nautilus was waiting. William placed Alena on the wooden walkway, and she immediately wrapped him in a hug.

When she pulled away, she wrapped Nemo in a hug as well. She then told both of them, "I'm glad you got to visit, Uncle William and Uncle Nemo!"

Both men smiled brightly before the captain spoke, "We are glad as well, Alena. We had a lot of fun, today."

Alena nodded excitedly before William added, "We are so glad that we got to meet you, Alena. You are a special little girl."

"I must second that," Nemo added. The dark-haired little girl smiled brightly at them before she wrapped them in another hug.

As they pulled apart, Killian spoke, "It truly has been a wonderful day, mates. I'm glad I got to see both of you."

"That goes for me, too. Next time, don't wait six years to make a stop here," Emma added, with a smile.

Nemo and William grinned at her words before the younger Jones spoke, "I don't think you'll have to worry about that."

The captain then glanced at his watch and told them, "William and I must be off. But today truly has been a memorable one."

Emma and Killian smiled at his words before they exchanged hugs with he and William. The two men then made their way toward the submarine. With one final wave, they stepped into the Nautilus. A few minutes later, Emma, Killian, and Alena watched it sink beneath the waves.

The blonde then heard her daughter sigh from beside her. So, she bent down on Alena's level and asked, "Hey, kid, what's wrong?"

"I miss them, Mommy," Alena answered with a downcast expression. Emma stroked her daughter's curls before she pulled her in for a hug.

Emma then told the little girl, "It's like Daddy has told you – Nemo and William's life is at sea. But it doesn't mean that they won't think about you. That's why they came for a visit today – they were thinking about your daddy."

"So, they'll be thinking about me, too, Mommy?" Alena asked with big blue eyes.

"Absolutely. About you, Daddy, and me – because they're our family," Emma assured her with a smile.

Alena smiled back before she pulled her mother in for another hug. As they pulled away, the little girl looked up at her father and asked, "Daddy, can we go sailing now?"

Killian couldn't help but chuckle before he answered, "Love, we've all had a long day with the visit from your uncles. I think we should wait until tomorrow."

"But Daddy," Alena protested with crossed arms, and Killian couldn't help but think that she looked like Emma when she did that.

He then bent down on her level and told her, "I mean it, love. I know you want to sail, but you're going to have to wait until tomorrow." He then proceeded to tease her a bit, "I think you can handle that, eh, First Mate?"

Alena's eyes lit up as she answered, "Aye, aye, Daddy!" Emma couldn't help but grin before Killian corrected her, "That's Captain to you," before he tickled her sides.

She giggled before she pushed her father's hands away. She then asked, "Can we eat at Granny's? She makes the best chicken tenders."

Emma and Killian both grinned before the blonde spoke, "And the best grilled cheese and onion rings."

Killian then said, "Well, my loves, I say it's a plan," as he ruffled his daughter's hair. Alena smiled brightly before her parents rose to their feet.

The little girl then began to skip along the docks as Emma and Killian entwined their fingers and walked along behind her.

Emma then told her husband, "I'm really you got to see your brother and Nemo. It makes me happy that you still have family."

"Love, you and our daughter are my family. And so are your family – they're our family, Swan," Killian pointed out.

"I know that. It's just that, well, I know how much losing Liam hurt you. And while no one could replace him, I am glad that you found William and Nemo," Emma told him.

The pirate smiled at her before he kissed her cheek. He then told her, "You are right, Swan. They are my family. I spent so many years being alone that I forgot what it felt like to be part of family. But then I met you, and everything felt right for the first time in years. And then I was able to have a proper goodbye with my brother and my father in the underworld; shortly after, I was reunited with William, and we were able to make things right. And I can't tell you how happy it makes me to have he and Nemo as a part of my life."

"As happy as I was when I realized that Storybrooke was my home. And that the people in it were my family, and that Henry and I belonged here," Emma began. She then squeezed his hand and continued, "And that I did, in fact, have feelings for one dashing pirate."

Killian smiled brightly at her before he told her, "And that kiss, love, is still one of my favorites." Emma returned his smile in response.

She then seriously asked, "Remember when you told me that I was your happy ending?"

"Of course, love," Killian answered, a bit confused.

Emma then clarified, "I was thinking about what Nemo told you all those years ago – about how what you were missing in your life was family, and he was right. I'm only part of your happy ending. Our beautiful little girl, and your brother, as well as Nemo, are the other part. We all make up your happy ending."

The dark-haired man smiled brightly at her. She truly was a bloody marvel. He then stopped walking, and she stopped as well and looked at him curiously.

"What are yo…" Emma began, but she was interrupted by Killian's lips on hers. The kiss was sweet and, and it was full of love and passion.

As they pulled way, Emma couldn't help but notice that their curious little girl was staring at them with a mischievous-looking grin.

The blonde only shook her head before she motioned to Alena and told her husband, "You know, that grin she's wearing looks exactly like yours."

Killian couldn't help but chuckle before he agreed, "Well, love, I think she inherited quite a lot from me." He then added, "Much to the disappointment of your parents, I'm afraid, who wanted a little princess."

Emma laughed at his words before she lightly hit his shoulder as she told him, "You know my parents love you, Killian, and our little pirate princess."

"I know, love," he simply responded. He then seriously continued, "And the love of my family does make up my happy ending, Swan, and I get to live it every single day."

Emma smiled at him before she pulled him in for another sweet kiss, one was that interrupted by their six-year-old.

"Mommy, Daddy, I'm hungry!" she exclaimed.

"Alright, love, we're coming," Killian assured her. Alena nodded before she took her mother's hand and her father's hook in her hands. She then proceeded to lead the three of them to Granny's.

Emma only shook her head while Killian grinned. There really was no mistaking that Alena was his daughter.

As they continued toward the diner, Killian couldn't help but think that, like William and Nemo, his life once belonged to the sea. If someone had told him that he would give it – and his ship – up for a woman, he would have called them mad. But as he looked over at his beautiful wife and at the lovely little girl that they had created, he knew there was no place else he would rather be in all the realms. He was exactly where he was meant to be.

Okay, y'all, I must confess I had no idea how to write Nemo or William, but y'all know that I tried my best, and I do hope you all enjoyed this one-shot! :)
