6 Months Ago:

"Come on, Sammy!" he yelled loudly at his brother.

"Hold your horses Dean" Sam replied as he stepped out of the car. He unconsciously started smoothing wrinkles out of his 'FBI outfit'. "We need the badges by the way" he reminded.

They walked to the back of the gleaming impala and dean popped the trunk. With the shotgun in place he started searching the trunk for the box of constantly changing federal badges. He threw one to his brother and got one for himself.

"Who are you this time?" he asked Sam.

"James Taylor, you?"

"FBI agent McGinty, boy-yo" he replied in a weak faux-Irish accent.

They closed the trunk, turned around and walked into the police station. Following the hallway they walked into the small main room of the station. It only had two cells, one occupied by a grumpy looking drunk midget, two large wooden desk, a computer and a couple of filing cabinets. One officer, who looked to be in his late twenties, was currently writing a report when he turned around and noticed them.

"Can I help you?" asked nervously while eyeing them suspiciously.

"Where looking for the sheriff, we're FBI agents Taylor and McGinty." Sam replied wondering why the officer was nervous.

"Deputy Nolan." Deputy Nolan stated. He motioned for them to follow, turned around walked two meters and knocked on Emma's office door before opening it. "The FBI is here." He said to his blonde daughter. He saw terror run across her face for a second until she composed herself and donned an impassive mask. She nodded once at him.

"She'll see you now." He said letting them into her office and dismissing himself.

"Afternoon, I'm Sheriff Swan. Welcome to Storybrooke."

"Thank You. I'm Agent Taylor and this is my partner Agent McGinty." Sam replied. He and Dean both held up their own badges.

"Like the rock stars?" Emma questioned suspiciously.

The brothers both feigned looks of confusion, they knew people sometimes recognised their fake names and had planned for this. First they would look confused and then asked what the person meant. It didn't occur very often but it did happen.

"What do you mean?" Dean replied in a cocky flirt, hoping to disarm her suspicions. He did find the blonde really attractive, especially in the red leather jacket she was sitting in. But he was in a committed relationship.

"Never mind, what can we do for you boys?" the sheriff asked.

"We're following a serial killer that we think might be in town. Have there been any missing townspeople or attacks at night? Maybe any weird deaths?"

"No, none of that but can I ask you two a question?"

"I don't know, can you?" Dean replied cockily, bulging a cheek and grinning. At the looks he received his faced returned to a serious expression. "Yes, sorry."

"Why are you two lying?" she asked still not giving anything away.

"What?" Sam forced a laugh that came out nervous. They had never been caught that quickly.

"Deputy Nolan!" Emma yelled as she jumped up from her seat, her gun trained to Dean's chest.

"Fuck!" Dean cursed under his breath.

David ran in and looked at the scene. Pulling out his own gun he trained it on the larger one and yelled at them both to lie down on the floor. They complied out of fear of being shot, not that it would be the first time. They wore both cuffed, searched and relieved of their weapons, and escorted out of the tiny office and separated into the tiny cells.

"Put the short one with Leroy" Emma yelled at her father.

"Hello brother." Leroy grinned darkly. Dean felt a tinge of fear at that moment.

"Let's start again. I'm Sheriff Swan and you are?" she said to Dean. Obviously he was the one in charge.

"My name is Damian McGinty. I am an agent with the FBI and that is my partner James Taylor. Listen, you don't have to trust us, call our boss. His name is Robert Singer, here's his number." Dean held out a business card with the number and name on it. It looked completely identical to the real ones and would lead her to an automated voice message from before Bobby died. It should be enough to at least convince her. She thankfully took the card.

"If I call this will I reach the real Robert Singer?" she asked not believing them.

"Yes." Dean replied.

"If I call this will I reach a real FBI agent?" She asked, adjusting the question slightly.

"Yes."

"Since you stepped in here, you have both lied about everything, except for this Robert Singer. What are your real names and I'll consider not calling the marshals immediately to escort you to federal prison. Impersonating FBI agents is a pretty big offence and judging by the badges you flashed you have been doing this for a while." She said giving them a stern look. She needed them to buy this bluff, she couldn't risk more people coming to Storybrooke, least of all the real feds.

They remained silent, knowing they were caught but also knowing they couldn't risk exposing the truth of this world to civilians. The truth about the things that go bump in the night. Other hunters would take their place and keep the monsters at bay. Emma sensing they wouldn't budge sighed and moved back into her office. After an hour the sheriff emerged from her office and walked to Dean's and Leroy cell. She opened it and let Leroy out.

"Thanks Sister."

"See you tomorrow Leroy" she smiled at him. Leroy actually had stopped drinking altogether two years ago when he decided to pursue Nova after he almost died from alcohol poisoning. He just liked the familiarity of the cell as it was his almost second home for thirty odd years. He would spend his lunch hour in there every day. While there he usually talked with Emma about how his relationship with Nova was still strong and that they were expecting twins. "Say hi to Nova for me!" she called after him.

"Will do, enjoy the rest of your day Emma!" he yelled back from the exit.

"Well, that's it for me Dad. Ruby should be here by five for the night shift with Dorothy. Are we still seeing you and Neal tonight?" she asked in a softer voice not wanting to let the two outsiders know anything.

"Yes, but I wish you would let me bring your mother along." He sighed at the greatly exasperated topic.

"You know I have forgiven both of you for all that has happened, but until she admits her faults and apologises to Regina for attacking her, she is not welcome." She sighed for the same reason.

"I know, but she was just shocked when you two told us that you were dating."

"You were also shocked, but you didn't attack her. And you at least approve of us."

David was about to retort that Snow approved but he knew that would be a lie. So he simply shrugged and greeted his daughter. She made quick work of her office, longer than usual as she couldn't risk having the two strangers see magic. She walked out of her office, greeted David again and walked out of the station. Once outside she basked in the warm sun after her morning shift. She raised her hand and poofed home. She saw the foyer of the mansion come into focus and the tension left her shoulders. She took off her boots and hung her coat. She heard singing coming from the kitchen and followed it to find her fiancé in the kitchen. Regina was currently in sweatpants, thick wool socks and an incredibly oversized sweater that hung like a dress. She was dancing and singing along to some pop song while baking. Emma snuck up to her fiancé and hugged her tightly from behind. Regina screamed and blushed when she realised her fiancé had caught her like this. Again.

"You're home early." Emma started.

"I wanted to surprise you with food. Just three months until we marry, dear."

"I know, but I can't help but think you want to be a little fatter for our wedding." The blonde said while resting her head on the brunettes shoulder.

"You know I love those muscles you seem intent on hiding." She said stoking Emma's lower arm with her index finger.

Emma turned her head and left soft kisses down Regina's neck. The mayor leaned her neck in the other direction to expose more skin. Emma let her hands wander to her fiancés rear, groping the mass gently. Regina turned in the blonde's arms and kissed her sensually on the lips, causing the blonde to moan.

"How was your shift?" she questioned staring into green eyes.

"Two new people rolled into town, fake FBI. Good fake to, would have believed them if I didn't have my superpower."

"That's not good, what are we going to do with them?"

"No idea, was hoping you would have an idea."

Taking a moment to think about their options Regina started formulating a plan. She would need a few ingredients and some time but a couple of forgetting potions would work.

"Forgetting potions should do the job."
