After the curse, after season 3. I'm assuming in this story that after all the fighting is done and everyone settles into normal lives (after the show ends), and Hook is great friends with Charming and is his naval captain. I really hope that Snow and Charming's next pregnancy is twins, so I made it so in this story.

This is my first Once Upon A Time fic, so please review with feedback, it'd be nice. Did I do the characters fine? If so, there may or may not be another one-shot, probably of Hook and Emma. Enjoy!

Killian Jones knocked on the door with his hook, annoyance and anxiety rushing through him. Through the door, two very loud, shrieking whales could be heard. Everyone in this wing- hell, everyone in the whole bloody castle- could hear the sounds. Hook was one of the few brave enough to decide to make a complaint about it.

He was already in a grumpy mood- Emma and her mother had gone off for the weekend. Snow needed a break from the babies, and she thought spending a few days alone with her already grown daughter would help relax her. Hook was worried because they hadn't brought along anyone else; it was just the two of them. He didn't want her to get hurt.

The former pirate captain and now just captain of the navy was about to knock again when the door swung open.

Prince Charming, holding a small, kicking baby in his free hand, sighed in relief when he saw his captain. "Thank God." He gestured him in hurriedly, and Hook entered his quarters slowly.

Once the door was shut behind him, Hook turned and was about to begin his speech about how a prince- a king- should be able to take care of two children, when suddenly one of those said children was shoved into his arms.

Instinctively, Hook wrapped his arms around the child, his handless arm closer to his body with the other farther away. When he was sure the baby wouldn't fall from his arms, he turned to the prince who had hurried back over to the other child and was picking her up, his eyes wide with fear and anger. "Are you bloody mad?! I have a rather sharp hook for one hand!"

Charming rolled his eyes as he rocked the baby in his arms. "I trust that you'll use it properly. And we both know you're better off with that than the fake hand."

Hook mimicked the other man's movements, rocking the baby in his arms.

"You'd think having a baby would be easy, but twins?" He scoffed. "They're hungry. I'll be right back with their bottles."

Hook stepped towards the already vacating Prince. "Wait, what am-" But Charming was already gone. It was just Hook and the squirming, crying baby in his arms.

He continued to rock the baby, but it would not stop yelling. His face was red with exertion, his eyes running with tears. His arms reached for the air, trying to grab on something that was not there.

Hook didn't know what else to do. He lifted his hand, shifting the baby's weight to hold him better, and stuck his finger out towards him. He put his finger under the swinging arm, which the boy then gripped after discovering its' presence. The baby squeezed his finger, and his yelling lessened slightly. Hook smiled, seeing that he was calming the baby.

Then he started talking to him. "You're alright now, lad. Your father is going to go get you your bottle, and soon you'll be warm and full and sleepy."

The baby stopped flailing and gripped Hooks finger tighter, as if to encourage him to continue. He did. "You're going to grow up in the Enchanted Forest, not that blasted place with loud sirens and machines that hit people and bruise their ribs." He chuckled at the memory. "Here, you'll learn to wield a sword, like men are supposed to. You'll protect your twin sister, and your older sister will protect you."

Saying that, he realized that the child he was holding was Emma's brothers, not just Charming's son. His smiled deepened into a grin. "How would it sound if I told you that I may be your brother-in-law one day?"

The baby boy blinked up at him, blue eyes shining with his tears. Hook took the silence as a good sign. "How would you like to be a pirate?"

A cough sounded behind Hook, and he spun around to see a small grin on Charming' face. He shook his head. "Now that's not happening." In his free hand he held two bottles.

Hook didn't understand how he hadn't heard the screaming child earlier, and gently pulled his hand from the boys grip and grabbed a bottle. Both men put the tip of the bottle into the baby's mouths and watched them drink.

Hook grinned up at Charming. "Sorry, mate, but one of your children have to live a dangerous life."

Charming grinned back. "Don't you think Emma's already done that?"

Hook chuckled and looked back down at the baby in his arms. "Aye, she has."

Charming stared at him another moment, seeing the way he rocked the child. "You're really good with him, Killian. Still not sure if you're father material?"

He and Snow had somehow decided that they would call him Killian, without any consulting between the two of them or even Killian himself. He chuckled again, a rather sly remark on his tongue, but decided to take the compliment, if that was indeed what it was. Charming somehow knew his doubts, and Hook wasn't sure if he liked that. "I don't-"

"Hook?"

He looked up and over to the sound of the shocked voice to see Emma, with Snow following her into the room. She was staring wide-eyed at him, frozen. He grinned at her, all worries of her safety forgotten, joy at seeing her alive and well spreading happiness throughout him. "Good evening, Swan." Though her parents had begun to call him by the name given to him by his parents, she would always call him Hook, just as he will always call her Swan.

Snow smiled at the sight of both men, and approached Hook. She smiled up at him. "Thank you for helping." He nodded back to her, then the baby boy was shifted from his arms to hers. She smiled down at her son, then stepped over to her husband. They smiled at each other, shared a kiss, then held their children together.

Hook stepped farther away from them, next to Emma, to give them privacy with their twins. He looked at her to see that she was still staring at him, only slightly shocked.

"You're good with kids…."

He gave her a grin. "Does that surprise you, love?"

She rolled her eyes, the trademark one that resulted with a small smile at his charm. "No, not with your age."

He frowned in mock hurt that she brought up his age.

Emma gestured for him to follow, and the two left her parents alone with their newborn children. Once the door was sealed shut behind them, Hook asked how her trip went. As he listened to her vaguely describe their trip down the river and how they encountered a group of talking gnome-hounds, he grinned. He was glad that his Swan had returned home safely. His days had been boring and stressful without her. Now they could continue their daily ritual of him flirting with her and her rolling his eyes.

Now that she was at his side again, he was complete.
