A/N: Hey all! This is just a short drabble on Once day inspired by a reader request for the handshake from 'Community.' Henry and Killian have their own form of greeting/celebration and Charming is slightly jealous. Takes place as all of these do in a time of peace in Storybrooke. No angst or big bads in sight.

Watching through the doorway into the backyard of their house, Emma couldn't help but smile widely. Outside on the lawn were three of her favorite people, Henry, Killian, and her father, and they were all currently working on something under the careful captaining of her son. It was some sort of complex building project that Emma didn't really understand but they all seemed fascinated with. At least she assumed they were since they'd been outside working on it for an hour at this point.

"They look like they're having fun." Emma pulled her eyes from the scene before her to her mother who gave her an easy smile that Emma returned.

"They deserve it. Between things being so busy at school for Henry, and Dad and Killian working on that case this week, they could use the down time."

"We all could."

Emma agreed with that whole-heartedly and looked back outside, happy that things were going so well. This was a truly peaceful moment and one that all of them had been fighting to get to for a long time now, and when she saw Killian and Henry exchange a happy look and a laugh at one point, it made her whole being light up.

Very few things compared to the feeling that came when she saw Henry letting Killian in because to Emma it was a second chance for her kid to have someone like a Dad in his life. It was painful for both Emma and Henry to lose Neal because he was Henry's father. Henry might not have known him long, and the relationship might never have had a chance to really flower but Henry deserved someone to look up to, who could answer questions Emma and Regina might be less equipped to handle. Someone who might have insights that Emma never could, or who at the very least could be another shoulder to support her son.

David had stepped up in a lot of ways over the years, but at the same time he'd of course made missteps as everyone is prone to do now and again. To this day Emma shuddered thinking about how her father had let Henry drive when he was so young. It was reckless and dangerous, and they were all lucky that no one had been hurt. Still as bonded as Henry and her Dad might be, there was something different when it came to Henry and Killian, a humor and a lightness that her Dad just couldn't seem to find.

It started when Killian was so willing to let Henry introduce him to all things 'real world' and it bloomed from there. The relationship wasn't always perfect – Henry was a teenage boy after all and they were all of them still learning how to make this unconventional family work – but it was largely good and there were new habits and customs forming that tended to make Emma smile.

Like the handshake; and Emma called it 'the handshake' because it was starting to get a reputation. People outside of the family were noticing it, not because it was elaborate, but because it was something that seemed to be happening more and more frequently. Including right now, when it seemed that they'd made some sort of progress on their project. Emma watched as Killian and Henry each slapped each other's hands twice as Killian brought his hook and Henry brought his other hand to his chest.

"So what, you're just going to leave me hanging?"

Emma saw Killian's smirk at her father's words after Killian and Henry had clapped hands, but he indulged her father and the end result was an identical embrace. Her Dad looked thrilled to be a part of it, but Killian and Henry both looked doubtful and David replied to that.

"What, did I do it wrong?" Henry and Killian shared a look before Emma heard her son respond.

"It's not wrong per se, Grandpa, it's just… not exactly right." Emma smothered a laugh as her father stood up straighter, a look of determination settling across his features.

"Okay so show me." Killian caught Emma's eye from where she was in the doorway, and she knew then that Henry and him were teasing for sure. The sparkle in his blue eyes gave him away.

"You need to loosen up a bit, mate. Too stiff and you throw the whole thing off."

"Fine, how do I do that?" Killian looked to Henry.

"I leave this to your expertise, lad. What's a man to do in this situation?" Henry looked somber and Emma had to admit he had a great acting face. For a family that was so terrible at keeping secrets that was impressive.

"You'll have to shake it out grandpa."

"What?!" Emma heard her Dad's sound of alarm, but he didn't back down and eventually followed Henry's instructions. As he was doing so, her mother approached and looked out into the yard too, laughing lightly when she did.

"Oh, David. Don't tell your father I told you this, Emma, but he's a little jealous." Emma's eyes flicked back to Snow quizzically.

"Jealous of what?" Her mother replied in a stage whisper.

"The handshake. Your father feels he's being left out a little bit. He's used to Henry finding him a little stuffy, but with Killian it's proving a little harder."

This pulled a chuckle from Belle who appeared at the doorway at that moment. Emma and Killian had been inviting her to more and more get togethers like this, knowing that what Belle needed more than anything was real friendship. They were happy to include her in afternoons like this one so her own heart aches might pass a bit easier. Still Emma and her mother turned to see what part of the clearly funny situation had made her laugh.

"Sorry, I shouldn't make fun it's just… oh never mind."

"No go on." Emma wanted to hear what Belle had to say since she was pretty sure it would line up with her thoughts too.

"It's funny given where they started that's all. Prince Charming is jealous of his grandson because he doesn't have a secret handshake with a pirate captain." Emma and Snow both laughed at the characterization.

"It's certainly something. It did help when I told David that someday he could teach Neal his own handshake, but that will be a while from now won't it, honey?"

Emma watched her little brother giggle as her mother's voice went higher and she smiled. It would be a while yes, but her Dad could be patient. He'd wait forever for his family if that was what it took.

After a few more moments of letting her father carry on in a slightly ridiculous way, Emma decided to be the one who took pity on him. She moved outside and saddled up to them with purpose.

"I think you're ready, Dad. Don't you guys?"

Emma glanced over to Henry and Killian who both looked like kids caught with their hand in the cookie jar and they nodded. David was given the chance to do the exact same gesture again and with Emma's presence he was praised highly for it. They all then watched her father walk away back to Snow with a cocky smile and clear joy written out all over his face. Emma eventually turned to face Henry and Killian and speak her mind.

"I know teasing Grandpa is a favorite pastime for both of you, just try and be nice, okay? Give him a break every once in a while."

"Okay Mom."

Henry hugged her quick before calling after his grandfather to ask if he needed help getting anything from the truck where he was headed, leaving Emma and Killian alone. Killian's hand found its way into hers immediately, their fingers interlacing and Emma felt even better than she had before. Somehow Killian always made things better, even when they were fantastic on their own.

"I was just about to put him out of his misery, Swan." Emma gave him a look and he immediately recanted. "Okay maybe a few minutes more. But in the end I would have let Dave have his moment."

"I know you would have, because as much as everyone likes to pretend it's a one sided friendship, you like my Dad just as much as he likes you."

Killian shushed her as if her father's hearing those words would be the end of the world. She silenced his dramatics with a kiss, and laughed when she pulled back after taking it a little further than their company allowed only to see him in a bit of a daze. He talked a big game but at the end of the day he loved being a part of this family, and he really really loved Emma.

"Remember, be nice." He mumbled the words 'as you wish' under his breath and Emma's heart hammered in her chest as she made her way back to the steps where her mom was waiting.

Without any sort of planning Emma and Snow did the exact same handshake a silent gesture of their own celebration. Emma saw Belle grin in reply and she heard Killian's barked out laughter but continued on inside knowing as she did that he would come and find her soon enough.

And when he did they didn't share a simple handshake, but another kiss that held every bit of hope and happiness that their moments did these days.

Post-Note: Thank you very much to the lovely reader who suggested this show and this element. Sorry it took so long, but it was a pleasure to write.
