Hi guys, I am so sorry for taking so long to post this, I've been extremely busy with personal things and haven't been able to upload a lot of my stories for a while so for that I apologise! Anyway, here's chapter 4 and I still don't own OUAT or Mamma Mia, please enjoy!

"So, let me get this straight, this Emma Swan invited us here for her wedding so that we could surprise Mary Margaret?" David asked in confusion.

Regina rolled her eyes behind her sunglasses and nodded, this guy knew that something was up but Regina couldn't exactly tell him the truth, not when the other two were with them.

"Why? I just don't get it," he sighed in frustration as he flumped back in his seat.

Regina was beginning to get pissed off with this one; he was far too inquisitive for his own good. Robin, however, could sense that David was frustrating Regina and decided to step in before she ditched him out of the truck.

"Look, mate, we've all had a long day with travelling and what not so why don't we just leave all the questions for the person who invited us." The British said as he softly stroked his sleeping son's curly hair on his lap.

Regina smiled gratefully at the man beside her, she found him way more tolerable than David and he seemed like a good father. Father. There was that word again, one of these men was Emma Swan's father and there was no way of telling which one. From what she has already gathered, Emma could easily be any of theirs and, although she had only just met him, she prayed that it wasn't Robin. It may have sounded selfish of her but she had only met the man not even an hour ago and she could sense that there was a mutual attraction between the two so, hypothetically, if something were to happen between the two of them and it turned out he was her goddaughter's father, she was almost certain that Emma would hate her guts. What if the blonde wanted to try to reunite her parents?

The rest of the drive was spent in silence but as they neared the villa, Regina felt her stomach drop; she didn't think this whole thing through. Where were the three men supposed to go? She couldn't just trail them around the hotel as that would risk everything. Fortunately for her, as she switched the engine off, she spotted Emma carrying boxes of fruit into the back entrance. The men got out of the truck and grabbed their suitcases before they followed Regina towards where Emma was, looking at each other in confusion when they stopped again.

As Emma picked up the last of the boxes, her eyes widened and she dropped the box with a loud thud as she took in the sight in front of her. They must be her possible fathers but why was Regina with them?

"Regina?"

Regina smiled tightly as she went to stand beside the blonde. "Emma, these are the men you invited to your wedding... You know, as a surprise for your mother." She tried to get Emma to play along.

"Oh, right, yeah! Hi, I'm Emma Swan." She noticed that one of the men was holding a small boy in his arms, is it possible that she has a brother?

"Robin Locksley," the Brit said with a toothy grin, she immediately liked this one.

"I'm David Nolan."

"Humbert. Graham Humbert." The Irishman said as though he was in a movie, Graham sat silently throughout the whole drive, he wasn't one for talking but he had a feeling that that was all about to change and he was going to have to make friends pretty quickly.

Regina quickly realised that someone would need to go distract Mary Margaret if Emma was to get the men through the villa without them raising suspicions so the older woman clapped her hands together and smiled.

"Well, I best be going, there are a few things I need to discuss with your mother about tonight but I'll see you soon. Gentlemen," she nodded as she left.

David waited until Regina was out of sight before he spoke again but Emma was quick to interrupt him.

"I've set up a room for you if you'd like to see it, there isn't really anywhere for the little one to play but I can show you the shortcut to the beach, my mom doesn't use it anymore so you wouldn't be interrupted?" She asked, finally acknowledging her possible sibling.

Robin glanced down to his son and smiled, "Thank you, Miss Swan, but right now, I think we all need a bit of a rest." He joked.

Emma smiled. She already liked Robin. The blonde then nudged her head and gestured for them to follow.

Rather than taking them around the front of the resort, she had to take them through the back alleys so that way, Mary Margaret wouldn't know they were there. Every so often Emma would glance back at the three men following her and try to determine which one was her father, she thought that as soon as she spotted him she would know straight away but it wasn't that simple for her, they were all so different yet so similar. She could already tell that Robin was a good guy and a loving father so that put him at an advantage, Graham was too quiet for her to be able to know anything about him but then again, Emma could be quite secretive and quiet at times so it's possibly that she picked that up from him and then there was David, even though she had just met him she could see small similarities between them, however, that didn't mean that he was her biological father. At this point it could be any of them but Emma didn't care, she was just grateful that they all showed up. After walking for a few moments, Roland awoke in his father's arms and took in his surroundings before resting his head on his father's shoulder.

"Papa, where are we?" He asked in a small voice.

Emma turned her head and smiled at the boy, he was adorable that's for sure.

"Storybrooke, sleepyhead. Did you have a good nap?" Robin asked.

Roland smiled cheekily and nodded, Emma noticed that he strongly resembled his father; they had the same adorable dimples and toothy smile. She could feel a small pang of jealousy come over her as she listened to the father and son interact, she wasn't going to lie, it hurt witnessing her possible father comforting and hugging his child when she never had that. She was snapped out of her daze as Robin walked a little faster so that they were now walking side by side with David and Graham trailing behind, invested in a conversation about god knows what.

"He's a cute kid," Emma smiled, nodding her head towards the boy in Robin's arms.

Robin smiled back, "Do you have any siblings?"

'It depends on whether you're my dad or not," she thought to herself. "No, my mom always said I was enough for her, it's just been the two of us my whole life."

Robin furrowed his brow. "What about your father?"

Emma looked away before thinking carefully about her answer, "I, uh, he doesn't know I exist."

The Brit smiled sadly at her, he felt a strong sense of sympathy towards the young blonde, he couldn't imagine growing up without a father but he couldn't help but feel angry towards her father for walking out on her and Mary Margaret. Both women deserved so much better.

"Hey, sorry to interrupt but how much farther is this place?" David asked from behind them.

Emma suddenly stopped outside of what looked like an abandoned goat house and turned to face the men, "This is it." She said before unlocking the door and leading them upstairs into a large attic. David grimaced at the sight of the place as Robin and Graham chuckled, it seemed as though David grew up with a silver spoon in his mouth and wasn't used to living in such a place. The American watched his two companions follow Emma up a ladder before he scoffed and picked up his bag, trailing behind them. He would just have to make do with this; after all, he just wanted to find Mary Margaret even if he had to sleep in a stack of hay.

Thank you all for reading, again, sorry for the wait but I hope you enjoyed this and I'll hopefully be back soon, please leave a review and let me know your thoughts, until next time
