All Emma Swan had wanted to do was give her parents a simple anniversary gift.

Okay, so maybe her home movie idea hadn't exactly been simple – more like next to impossible, as it turned out. But still, in all her imaginings of worst case scenarios, some minor bouts of irritation between her and Regina were the extent of it. The two of them had a rather tenuous working relationship. Frustrations easily built between them but they just as easily let said frustrations go enough to push forward with the project.

Never in a million years had Emma thought that a potion could go so horribly wrong. Never in her wildest dreams had she imagined the potion blowing up in her face, accidentally transforming her husband and herself into small children. One wrong ingredient and a simple memory extraction had become their own personal magical DeLorean!

Emma was mortified.

Neither she nor Killian remembered the potion going poof. As far as they were concerned, one minute they were adults and the next they were rugrats. Which was all well and good but that also meant Emma had no idea what they'd done wrong. Hopefully Regina knew because spending two days as a ten-year-old was not a mistake Emma intended on repeating any time soon, thank you very much.

"And Regina never said what the wrong ingredient was?" Killian was asking her parents.

"No, she didn't," Snow replied.

"And we didn't ask because we kind of had bigger things going on," David added, a teasing lilt in his voice. "Well, littler things. You know what I mean."

Emma gave him a sheepish smile. Yeah, she did know what he meant. She couldn't even imagine how they must have felt to be presented with a couple of ten-year-olds in place of two grown adults.

Before anyone could say anything further, what sounded like a herd of elephants bounded down the stairs. Said herd revealed itself a moment later to be Henry, holding a freshly changed baby Neal, and Wilby, who trotted along at the kid's side. The second Henry's gaze landed on Emma and Killian, a grin broke out on his face and he ran at them full force.

In less than a second, savior and pirate found themselves crushed in a hug with a teenager, a baby, and a dog. "Oh, I'm so glad you're back!" Henry exclaimed, his voice choked with emotion. "I mean, don't get me wrong. You guys were really fun when you were little but I missed you so much."

"We missed you, too, lad," Killian murmured into his hair. "Thank you for being such a wonderful playmate."

Neal babbled at a frantic pace, waving his fingers through Emma's hair and giving little squeals of delight. The memory of playing with him and making him laugh the day before hit Emma square in the chest. Her tiny baby brother had loved her in her kid form and he loved her now. "And we missed you, too, squirt," Emma said around the lump in her throat as she lifted her brother from her kid's arms.

Her parents got a loving chuckle out of that one.

But it was Wilby – sweet, loyal Wilby who'd clung to her side the entire time she was little – happily pawing at her legs that made Emma lose it.

The tears seemed to arise from every emotion. Joy that she'd finally found people who would stick by her. Anger at those in her life who hadn't. Pure, unadulterated love for her family. Sorrow for the lonely little girl she'd once been. Happiness that the lonely little girl had finally gotten a taste of what she should have had. Sympathy for the frightened little boy Killian was. Delight that he now had some happy childhood memories, too. Pride for the way her entire family had come together to include him.

And Killian … the memories came back to her now, the way the two of them were drawn to each other even as children. The way she protected him and the way he took care of her. The way they comforted each other and encouraged each other.

Even as children, they shared True Love.

The emotions were far too much for someone who'd been ten years old a minute ago.

"Oh, sweetheart," Snow murmured as she and David joined the group hug. Another memory pushed its way to the surface: Emma telling her parents that she liked their pet names for her. Kiddo from David and sweetheart from Mary Margaret were the first pet names ten-year-old Emma could remember being called. She'd adored the idea that these two people cared about her enough to have special names for her.

The six of them plus Wilby stayed in the hug, sharing love and comfort, until Emma's tears stopped falling. "I'm sorry," she said sheepishly when everyone separated, sniffling back the last of their tears. "I've got kid emotion and adult emotion running through me at the same time and I guess I'm still a little overwhelmed."

"You don't have to apologize, kiddo," David said around the tremor in his own voice. He smiled gently, drying Emma's cheeks with the sides of his thumbs. "It's perfectly all right."

Once emotions had settled, Henry asked, "So you do remember everything, right? How do the memories feel to you?"

Sensing that Emma wasn't quite up to answering just yet, Killian took up the gauntlet. "Sometimes they feel like they were only yesterday – because, well, they were – but other times they feel like they were ages ago."

Emma nodded in agreement. "It's weird. They're vivid because they just happened but they also have a faded edge to them as if they'd happened when I was really ten."

"Aye. So yes, lad, we do remember and we can't thank you all enough for taking such good care of us."

"It was our pleasure," Snow assured them. "Thank you for giving us such a wonderful opportunity."

Emotion threatened to overtake Emma again so she did what she did best: deflected it with a joke. "So what you're saying is we need to make magical screw-ups more often."

Just as she'd hoped, everyone laughed. "If more magical oopses mean we get more Mario Kart, then yeah, you do," a cheeky Henry replied.

Though the mood in the room had lightened, Emma still felt the need to go splash some cool water on her face. She excused herself to do just that and headed upstairs to the bathroom. On her way down the hall, she passed the room she and Killian had stayed in, the one that still looked like the loft in the tiny apartment she'd shared with her family.

She stood at the door a moment, taking in the detritus of life with children. A pair of socks lay on the floor next to Emma's bed and books covered Killian's nightstand. The mini planetarium Henry had given them still sat on the bed where Killian had slept. The dresser drawers were filled with tiny clothes.

It amazed her how quickly her ten-year-old self had felt comfortable in this room. She couldn't possibly have recognized the furniture but on some level, had she known that she'd belonged here?

"Emma? Are you all right?"

Emma jumped at the sound of her mother's voice. "Yeah, I'm fine," she said, turning around to face Snow.

Snow gave her such a knowing, motherly look that Emma's heart caught in her chest. "No, you're not. What's going on?"

"No, I really am. I was just thinking … this room, well, the apartment with you, it's the first home I ever had." The touched sparkle in her mother's eye gave her the courage to continue. "And now it's the first home little me remembers, too."

Yep, that totally did it. Tears welled in Snow's eyes as she wrapped her little girl in a hug. "I'm so glad we got the chance to know you."

"I'm glad I got the chance to know you," Emma murmured. "And I'm sorry you had to let me go."

Snow pulled out of the hug and held Emma at arm's length. Her love was etched on her face and her voice was strong and sure. "I'm not. You, Emma Swan, are my baby. You always will be, no matter how old you are."

At that, Emma felt another rush of emotion: pride and comfort and joy at being somebody's baby.

Once their emotions were back under control, Snow and Emma headed back downstairs. Emma met Killian's gaze across the living room and he instantly gravitated towards her. "You all right, love?" he murmured, wrapping his arm around her shoulders.

"Yeah," she replied as she leaned into him, resting her head against his shoulder. "Are you?"

"Aye. Your family gave me the chance to know what being in a family felt like. Those are memories I will treasure for the rest of my days."

That they were.

"And I would just like to point out," Killian continued, shifting his voice to reflect a gentle teasing, "that even though we didn't know each other at all, we still made quite the team."

"Yeah, we did, didn't we?" Emma mused. "We must have felt it even then, our True Love. We were just too young to recognize it for what it was."

Killian beamed at her before pressing a kiss to the side of her head.

The kitchen was finally clean and David emerged into the living room. "I don't know about anyone else but we've got all day and I don't feel like going anywhere. Who's up for another day of hanging out?"

"Does that mean more Mario Kart?" Henry asked, making everyone chuckle.

"I'm up for it if you are, kid," Emma shrugged.

Everyone was cool with that. After all the togetherness of the past couple of days, none of them wanted to give it up.

Emma did think, though, that she probably should thank Regina and Zelena for their hard work in fixing her little screw-up. Regina had dropped off the stuff Emma and Killian had left in the vault when she'd dropped off the books to Henry the day before so while Henry set up the video game, Emma went off in search of her phone.

Her unread messages were plentiful but one in particular from Zelena stood out: it was a picture of her and Killian, ten years old and curled up practically on top of each other, sound asleep in a pile of blankets. "All right, what the hell is this?" she asked, holding her phone out for everyone to see.

Snow, David, and Henry all giggled. "Zelena did say she sent it to you," David said. "Guess she wasn't kidding."

"Aww, we look adorable," Killian murmured. While he was mostly teasing his wife, the tenderness of his tone indicated the truth of his words.

"We do but really?" Emma huffed. "Did we really need pictorial evidence of my magical oops?"

"Then I suppose I shouldn't tell you about the pictures I managed to take on my phone, either," Snow laughed.

"Ooh, you have more?" Henry asked, oblivious to the furious blush coloring his mother's cheeks. "I want to see!"

Of course, Snow couldn't help but grab her phone and show off her photos.

Though she was thoroughly mortified, Emma crowded in with everyone to flick through her mother's pictures. And as candid photo after candid photo of video games and art projects and children playing together went by, she was struck by how relaxed and happy she and Killian seemed. The overwhelming love the family shared was evident in every frame.

So, okay, maybe she did have to make magical screw-ups more often. In trying to give her parents a gift, it turned out that Emma and Killian had given everyone a gift. Her parents had gotten to know the little girl they should have known while the lost little boy and the lost little girl had finally found what every child should have: the love of a family.
