Author's Note: I've seen a few stories where Emma had twins and I have one of my own, Double Trouble. That story starts in S3E12 and the OC twin sister, Mia, was never adopted and grew up in the system like Emma. I had some reviewers ask why Mia wasn't adopted by Regina, and it got me thinking about how some of the story lines from season one would have played out if Mia were living with Regina, too. So this is that story. You don't need to read Double Trouble for this to make sense. It's a completely different take on it. Emma had twins and Regina adopted both of them. The OC twin sister, Mia, and Henry are really close, but she doesn't believe in the curse and she didn't want to find Emma.

For anyone who is reading Double Trouble and this, Mia is still Mia with the same personality, but there are a lot of differences because she didn't grow up in the system.

Thanks for reading! If you like this, please let me know and I'll continue. I have ideas for the story lines through all of season one.

Chapter 1

"Come with me. Please," Henry begged. "I know you don't believe me about the curse, but she's still our mom."

Mia looked at her brother sadly, knowing he was just going to get hurt. "She's not…our mom. She didn't want us when we were born. Why would she want us now? She's just going to hurt you."

"You want to meet her…I can tell. You're just scared."

Mia bristled a little. "I'm not scared. I'm just…not interested."

Henry looked like he was resigning himself to going alone. "It's okay…she's going to come back here with me. You can meet her then. You're going to cover for me with Ms. Blanchard, aren't you?"

"Well, yeah…you might not be her favorite anymore if she knew you stole her credit card and skipped school to go on an unauthorized field trip to Boston."

Henry ignored her sarcasm. "Just tell her I'm home sick."

"I know. We have done this before…just – usually the roles are reversed. You're supposed to be the good twin. I finally corrupted you." Mia smiled proudly.

"We're both good," Henry said earnestly.

Mia scoffed. "I think Mom and Ms. Blanchard and, oh, Principal Daly might disagree."

"I know you're good. And so is our mom."

Mia blinked. "I thought she was the Evil Queen?"

"Not her!" Henry said irritably. "Our real mom."

"You don't know her," Mia said flatly. "She might not be good. She could be a total psycho or a serial killer for all we know."

"She's a bail bondsperson." Mia gave him a questioning look and he shrugged. "I Googled her."

That was actually kind of cool, but Mia tried to act unimpressed. "So she's a bail bondsperson…that doesn't mean she's good."

"She literally catches bad guys. She's going to save everyone."

"From what? Dying of boredom? Henry, she didn't want us. She's not going to save us from anything."

"She is. You'll see," Henry said insistently.

"I just don't want her to hurt you," Mia said softly.

"She's not gonna," Henry said confidently. "She's our mom."

This was bad…this was really bad. The adoptive mother of the twins she had given up for adoption was the mayor of all people, and it was clear from the sheriff's car parked in the driveway that the adoptive parents had called the cops.

Crap. Emma Swan knew that the birth mother bringing the missing kid back did not look good. And with her record…well, she didn't have a lot of trust in the justice system – or any system really. She just wanted to drop the kid off and go home, but she didn't know if it would be that easy. She took a deep breath and forced herself to get out of the car.

The kid's shrink had told her the mayor's house was the largest house on the block, and it was. It was a big, almost imposing white two-story that made every foster home Emma had ever lived in look like a hovel by comparison. This was where her…kids lived. It was a hell of a lot better than crashing in a car or a crappy one-bedroom apartment like they would have if she had kept them.

The lawn was perfectly manicured and the porch light was on. Before they reached the porch, the door swung open.

"Henry!" A woman cried in relief, rushing out and wrapping her arms around the kid. "Oh, are you okay?" The woman pulled back, grasping the kid's shoulders. "Where have you been?" The woman noticed Emma standing there awkwardly and looked to her for the answer. "What happened?"

"I found my real mom!" The kid yelled, running past the woman who was clearly his adoptive mother and into the house without a backward glance.

The sheriff was standing behind the adoptive mother, watching quietly, and looked torn between staying with the mother and talking to the kid.

Her kids' adoptive mother turned to Emma with a stricken expression. She blinked and shook her head slightly as she processed it. "You're their birth mother?"

Well, this was awkward…

"Hi," Emma said with a tight smile, feeling extremely uncomfortable.

"Where's Mia?" The woman demanded, looking past Emma to the street.

Emma blinked. "Mia? Oh, right, his sister. Um, she didn't come with him. He said she was scared-"

The woman scoffed and cut her off. "My daughter isn't afraid of anything. If she wasn't with Henry, it's because she didn't want to meet you."

Emma didn't know why the thought that her…daughter didn't want to meet her hurt, but it did. When she gave them up, she never thought she'd see her son or her daughter again so it shouldn't have mattered to her. But now that she'd met her son, she couldn't help but want to know what her daughter was like.

The sheriff cleared his throat softly. "So Mia's still missing, Madam Mayor?"

The woman frowned. "It would appear so. Sheriff, if you would be so kind as to go talk to Henry? If anyone knows where Mia is, it's him."

To Emma's surprise, the woman invited her in for a drink. She let out a relieved breath. It didn't seem like anyone thought she'd done anything wrong here, though the woman did question her on 'the father' and whether she needed to be worried about her or Neal. She didn't.

It was late and the only light came from the streetlights. Mia stood in a dark alleyway where she could peek around the corner to see anyone that got off the idling bus, but they wouldn't be able see her. The only problem was that no one was actually getting off the bus.

Storybrooke was a small town with one bed-and-breakfast and no tourist attractions. They didn't have a movie theater or a mall…or, well, much of anything. Mia knew it wouldn't exactly be a popular stop, but there should have been one person getting off there…her brother. It was the last bus back from Boston for the night.

Henry was so sure their birth mother would come back to Storybrooke with him. Mia wasn't.

Mia watched helplessly as the engine turned over loudly and the bus pulled away from the stop at a slow creep. Where was Henry? Was he alone in Boston? She should have gone with him…he asked her to go with him – several times in fact.

Mia could imagine her overly optimistic brother who always saw the best in everyone getting in the car with a complete stranger. She should have been there to stop him from doing something stupid. She just should have been there…the way Henry was always there for her.

Mia started the short walk home, hoping her brother would be there. She hadn't gone home after school because she didn't want to face Regina's wrath alone. Even though she wasn't the one that hopped a bus to Boston, she knew that wouldn't stop Regina from taking her anger out on her. Regina took her anger out on her a lot lately…or maybe she was really just that angry at her…still – for something that had happened months ago…something that she hadn't meant to do…something that would never have even happened if Regina hadn't been lying to them for ten years.

"Watch for Mom and let me know if she's coming back. I'm going to find my Gameboy."

Henry looked hesitant. "Maybe you shouldn't. She's already mad."

"At me, not you. Just, like, whistle or something if you see her, okay?"

Henry nodded reluctantly and turned to the door to the mayor's office. Regina was in a council meeting. They weren't allowed to stay home by themselves for that long and their mom had fired yet another babysitter. It sucked being grounded at home, but it was even worse being grounded in Regina's office where there was absolutely nothing to do without her favorite electronics.

Mia started going through Regina's desk drawers, looking for the Gameboy her mom had taken away earlier. When she came up empty-handed, she moved over to the filing cabinet. It was locked, but Regina left her purse under her desk. Mia rummaged through the designer leather handbag until she found her mom's keys in a side pocket. There was only one key on the key ring that was small enough to be a possibility.

Mia inserted the key into the lock on the filing cabinet and turned it, grinning triumphantly when she heard it click open. She returned her mom's keys to exactly where she found them and then went back to the now-unlocked cabinet, feeling good about the chances she'd find her Gameboy hidden in the bottom.

As she searched the filing cabinet, her eyes automatically went to a file folder with her name on it. She wondered what was in it and reached for it almost on autopilot. Her birth certificate was the first thing in the folder. She picked it up and looked at it curiously. Huh…the space where their father's name should be was blank.

Regina never talked about their dad - even though Henry had asked about him at least a hundred times. Mia had never been interested in the man that clearly didn't want anything to do with them, but maybe she could give her brother the answer he needed. She turned back to the folder to see what else was in it…maybe there would be something on their dad in it.

The next thing in the folder was a…Certificate of Adoption. For just a moment, Mia didn't understand. She wasn't adopted. But the certificate had her name and her birthday. It had her mom's name and signature at the very bottom. She almost couldn't believe her eyes.

Mia just sat there on the floor of Regina's office, reeling with shock as she tried to process this. It was right there in front of her in black-and-white…she was adopted. Everything she thought she knew was a lie. Why hadn't her mom told her? Was it just her – or was it both of them? Was Henry even her twin?

Henry…she heard him whistling in the hallway. It sounded so far away, but she knew it wasn't. She heard her mom – no, not her mom…Regina? – ask Henry what he was doing in the hallway and where she was. It didn't seem important to put the file folder away before they saw her anymore. She couldn't un-see the Certificate of Adoption or pretend like she didn't know so she just sat there numbly.

"Mia! What are you doing?"

"I'm adopted?" Mia struggled to form the words that were so strange to her.

"What?!" Henry shrieked.

Her mom hadn't been…well, her mom since that day – and not just biologically. Regina hadn't been herself. She was colder somehow. She'd always been strict, but she'd also been fiercely protective and loving. Now sometimes Mia thought Regina hated her.

Mia let out a long-suffering sigh as she turned onto Mifflin Street. There was an old, beat up yellow Volkswagen Bug parked in front of her house. She stopped walking and stared at it. Unease washed over her when she saw the Massachusetts license plate…their birth mother lived in Boston.

"Mia, your mom will be glad to see you."

Mia recognized the voice and turned to Sheriff Graham with a sinking feeling in her stomach. Regina called the freaking sheriff. She scoffed slightly. Of course she had - or maybe he was already there. It didn't really matter. He was standing there on the front porch, looking her over carefully for any sign that she was hurt.

Mia wanted to turn and run, but she just kind of froze. And then it was too late…he had a hand on her shoulder and was guiding her toward the house. She shrugged his hand off, but reluctantly went in with Graham right behind her.

"Madam Mayor?" Graham called out quietly from just inside the doorway. That was a little formal for the guy she'd seen sneaking out of Regina's bedroom earlier that week. Mia just shook her head and made a small disgusted sound. "Mia's home."

Mia heard the distinctive click of heels on the hardwood floor and then Regina was in front of her. "Mia! Are you okay? Where have you been?"

"Didn't you get my note? I left you a note," Mia said, already feeling defensive.

"Ah, yes…a note telling me you were going to a friend's house." Regina was calm, but Mia knew it was the calm before the storm. "You do not tell me what you are doing."

Graham was still standing behind her and Mia could feel the startling intensity of another gaze on her. That was when she saw the blonde woman standing a few feet behind Regina. The woman was just standing there, watching intently as Regina lectured her. This wasn't awkward at all…

Mia met the blonde woman's gaze for a second and then quickly looked away. She could feel her cheeks flushing. She hated that Regina was scolding in front of other people…especially these people – her adoptive mom's…boyfriend or whatever the hell he was and the woman that she knew somehow was her birth mother. It was embarrassing.

"You're ten. You do nothing without my permission," Regina continued, not seeming to care how uncomfortable Mia was.

"Nothing? Really? I need to ask you if I can go to the bathroom now?"

Regina's expression hardened. "This isn't going to the bathroom, and I think you know that. Unless you have my permission to do otherwise, you come straight home from school."

"Do not pass go, do not collect two hundred dollars," Mia muttered under her breath, but Regina heard anyway and narrowed her eyes.

"Is that clear?" Regina said sharply.

"Crystal." Mia turned to leave.

"Not so fast, young lady." Regina stopped her. "Did you know what your brother was doing?"

Mia shifted uncomfortably…she knew Regina would blame her. "No…"

"You really expect me to believe you had no idea that Henry ran away to Boston to find this woman?" Regina gestured toward the blonde woman, actually acknowledging her for the first time.

"I don't even know who she is," Mia said flatly.

The blonde woman looked uncomfortable. "I'm…I'm…"

"The woman who gave you up for adoption," Regina cut her off.

Her adoptive mom and her birth mother both seemed to be waiting for a reaction, but Mia wasn't going to give them one. She kept her face expressionless. "I'm really tired. Can you finish yelling at me tomorrow?"

"I'm sure you are," Regina said without a bit of sympathy. "It's way past your bedtime. All right, go to your room, not Henry's, and straight to bed. We'll discuss your insolence tomorrow."

Mia went to the stairs, forcing herself not to look back. Henry was waiting for her in her room. Well, technically Regina had only said she couldn't go to Henry's room, not the other way around. Mia dropped her backpack on the floor and flopped down next to her brother on her bed.

Henry turned to her. "Where were you?"

Mia stared. "Seriously? I'm not the one that went to Boston. You first."

Regina narrowed her eyes at her daughter's back as the little girl stomped up the stairs. Ever since they found out they were adopted, both of her children had been acting like ungrateful little brats. They had everything they could ever want, but they didn't appreciate any of it or anything she did for them.

They both had atrocious attitudes, but her daughter's was far worse than her son's. It seemed like the more Regina tried to rein in their behavior, the more her children pulled away from her.

Dr. Hopper said it wasn't just because they found out they were adopted. According to him, it was just the age. Apparently it was perfectly normal for ten year olds to talk back and have an attitude. Regina wondered if the 'doctor' that got his degree from her curse even knew what he was talking about. This certainly wasn't normal in the Enchanted Forest. She knew exactly what her mother would have done to her if she'd shown her an ounce of the disrespect that her children were showing her. She shuddered slightly at the thought.

She flinched when she heard a door slam upstairs and let out a frustrated sigh, stifling the urge to go up there right that second to deal with Mia's attitude.

She turned back to her children's birth mother with a forced smile. "I'm sorry. I really don't know what's gotten into them. And Henry…dragging you out of your life like this."

The blonde woman shrugged it off. "Kid's having a rough time. It happens."

A rough time? How exactly were her children having a rough time? Regina wondered what Henry had told this woman.

"You have to understand. Ever since I became mayor, balancing things has been tricky. You have a job, I assume?" She waited for the blonde woman to fill in the blank.

"Uh, I keep busy, yeah."

Regina pushed aside her annoyance at the answer – or lack thereof. She could easily find out just what it was that the woman did. "Imagine having another one on top of it - that's being a single mom. So I push for order. Am I strict? I suppose. But I do it for their own good. I want them to excel in life. I don't think that makes me evil. Do you?"

"I'm…sure he's just saying that because of the fairy tale thing."

"What fairy tale thing?" Regina tried to keep her expression innocent.

"Oh, you know, his book…how he thinks everyone's a cartoon character from it?" The woman said with a soft chuckle…like she thought it was cute. "Like his shrink is Jiminy Cricket?"

"I'm sorry, I really have no idea what you're talking about," Regina said with false calm.

"You know what? It's none of my business." The woman gave her a small smile. "He's your kid. And I really should be heading back."

At least this woman understood that. Henry and Mia were her children. This woman may have given birth to them, but Regina was the one who had done everything else.

"Graham! Henry and Mia have run away again! We have to-" The mayor stopped speaking abruptly when she noticed Emma in the jail cell. "What is she doing here?" She turned to Emma. "Do you know where they are?"

Okay, that sounded like an accusation.

"Honey, I haven't seen him since I dropped him at your house. And I have a pretty good alibi," Emma said pointedly with a glance at the cell she was currently in.

"Yeah, well, they weren't in their rooms this morning."

"Did you try their friends?" Emma asked.

"They are best friends…they're practically joined at the hip. And since I don't know where either one of them is, that doesn't really help me here. Any other brilliant ideas?"

Emma's next thought was to check their computers for emails, but they probably didn't need to email each other since they lived in the same house. There might be other clues as to where they had gone though. "Did you check their computers?"

"You've known Henry for a day. I've known Henry and Mia their whole lives. What makes you think you're the expert on finding them?"

"Finding people is what I do. Here's an idea – how about you guys let me out and I'll help you find them?" Emma offered.

Roughly ten minutes later Emma was in Henry's bedroom. Blue was his favorite color judging by the blue and white striped wallpaper and the blue, grey and white quilted bedspread. There was stuff everywhere…the bookshelf was filled with books and board games, there were drawings and posters on the walls, and planets were hanging from the ceiling over the bed. It was a nice room filled with all the stuff a kid could ever want.

Emma sat down at the kid's desk in front of his computer and went through his inbox and browser history. He had cleared both, but she knew how to recover the data. As she went through his email, she found a receipt for a website called whosyourmomma. Nice. So that was how he found her…

The website was expensive, and the kid had paid for it with his teacher's credit card. When they went to talk to the teacher, it was pretty clear she knew nothing about it and the kid had swiped the credit card from her at some point.

Emma had been trying not to think of these kids as hers, but she couldn't ignore the similarities between herself and her…son. She was actually really impressed that he found her when she hadn't even been able to find her birth parents yet – and finding people was literally what she did. And the running away and minor theft…well, the kid could have gotten those tendencies from her or Neal. The only difference was that she was running from overcrowded group homes when she was his age, and he was running from…what? The adoptive mother was kind of a hard-ass, but she didn't seem that bad. But if both kids were running away from her, maybe she was.

Author's Note: For Regina fans, she is probably my favorite character after Emma. I'm trying to show some of her point of view and will keep doing that if I continue this, which I will do if people seem to like it. I'm not going to change the way she acted in season one or her relationship with Henry though so she isn't going to suddenly be super nice. I also wrote a rocky relationship with Mia for a reason, although Mia does not think Regina is 'the Evil Queen.'
