Rob and Lauren Blakely stood outside their seventeen year old son's house. They could hear voices inside. Zac's deep voice laughed at something the more feminine said and the girl also began to laugh at her own comment. They had been in there for a half hour and Rob and Laura were starting to get concerned.

"Maybe we are just paranoid and Zac has a reasonable explanation of why he and that girl… what's her name again?" Lauren questioned her husband. Rob too have seemed to forgotten the girls name. Zac had been hanging out with almost every day, but still the parents had no clue what her name was.

"I believe it begins with an M" Rob said. Lauren nodded in agreement.

"I believe that Zac is a good kid and he wouldn't dare cheat on Evie. They have known each other since they were little and they have a bond that is still so strong. Do you see the way they look at each other?"

"Then why is he with her so often?" Rob replied, jerking his thumb toward the house. Lauren sighed in exhaustion.

"Why don't we just go in there and ask them?" Lauren turned away from her wide eyed husband and started walking towards Zac's tiny house.

Inside the house, Zac and his twin sister Mimmi were deep in conversation.

"I swear to you. The stupid snapping turtle bit my tail so hard in the middle of the exam. I screamed so loud that I think everyone back in the Northern Pod could hear it." Mimmi laughed remembering the event that made her brother laugh so hard he was gasping for air. Zac put his hand up, motioning her to stop so he could catch his breath.

A soft knock at his door silenced them both. They both looked at each other with confusion written across their faces. Another knock soon came after, this one much harder than the other. Zac got off the couch to go and answer it. Outside stood Lauren with a concerned look on her face and Rob with a much harsher look.

"Mum, Dad, hi. What's up? Zac said in a nonchalant voice. Mimmi could tell that her brother was trying to hide the concern in it. They had both on many occasions heard the parents whispering whenever she was around and sneaking glances towards her. The dad almost seemed angry at her but she knew it was silly. She had barely spoken two words to either of them since she and Zac found out they were twins four months ago. But she still questioned the fire in their eyes whenever she hung out with Zac.

"Hi honey." Lauren said in a sweet tone. "Can we talk with you and…" Her voice faltered and she nodded in Mimmi's direction.

"It's Mimmi" she said when she realized that Laura didn't know her name.

Lauren nodded. "Yes yes, Mimmi." She looked at Rob who nodded at her. Zac turned to Mimmi, his eyebrows furrowed in confusion. She shrugged and he let them into his room. Mimmi got off the couch she had been sitting on and straightened her flowy blue dress with tiny white shells all over it and smoothed down her long flowy dark brown hair held back in a white headband. She walked over to Zac, her white ballet flats tapping on the wooden floor. She tugged on Zac's navy blue shirt and motioned him to listen.

"Whatever it is, remain calm. Glance noticeably out the window if you want to make a break for it." She whispered into Zac's ear. He nodded, understanding the plan.

Rob and Lauren came inside Zac's house and looked around. Both of their gazes landed on the pile of prawns shells that the twins had left on the coffee table. The parents had noticed that Mimmi shared the same love of seafood as their son has.

Zac closed the door and motioned his parents to sit on the couch that Mimmi had recently abandoned. Zac then sat on the other small couch next to the one his parents were sitting on, and Mimmi sat on its armrest.

"How's Evie?" Rob blurted out, breaking the awkward silence. Mimmi and Zac looked at each other, confusion written across their faces.

"S-She's fine. What doe Evie have to do with anything?" Zac questioned.

"Is she fine with what is going on between you two?" Lauren joined in, adding to the conversation.

Mimmi looked surprised. "Yes. Why wouldn't she? She is happy that Zac and I found each. She is so happy that we are happy." Rob and Lauren looked concerned.

"Well I'm not!' Rob shouted, standing up and knocking over a glass of water. Zac and Mimmi jumped off the couch, trying not to get wet.

Mimmi looked over at Zac. He nodded to her, settling down her fears that he had not gotten splashed. Rob and Lauren observed this strange behavior.

Mimmi smiled sweetly. "It's a new dress. I don't want to get it wet."

"Dad, why aren't you happy for us?" Zac sat back down on the sofa and Mimmi followed his actions.

"Well I think that this whole thing is repulsive! No one should be doing this! Zac, I am completely disappointed in you. I thought I raised you better than that. How dare you be dating two girl sat once!"

He slammed his fist down on the coffee table, disrupting the pile of prawn shells.

"Dating two girls? Zac, what on earth is he talking about. Doesn't he know that you and I are…" Mimmi stopped and frowned. Pain quickly filled her dark blue eyes as she realized what was going on.

"Mimmi, I can explain" said Zac as Mimmi got up from the armrest and walk away from him. He quickly got off of the couch and grabbed her wrist. She spun around, pain and anger written all over her face.

Rob and Lauren watched the two siblings, unbeknownst to them that they were actually related.

"I thought you told them Zac! I thought you told them about me and this whole situation!" Tears began to flow down her cheeks.

"I thought you had finally accepted what has happened." She whispered. Mimmi yanked her hand away from Zac and turned away from him.

"I have accepted what has happened. You mean so much to me. Please don't leave." Tears were beginning to form in his eyes too.

"If I mean so much to you, than why haven't you told your family yet?"

Zac hesitated. He was unsure of what to say next.

"Oh I get it. You haven't come to terms yet." Mimmi walked closer to the door.

"They wouldn't understand what has happened to us!" Zac pointed to his parents, as if making a point."

"That's for them to decide. You know what Zac, I'm done. I'm going home. When you finally accept what has happened, you know where to find me. Until then, just leave me alone."

Mimmi walked the rest of the distance to the door and opened it. She took one last glance at Zac and shook her head. Tears still fell down her face.

"Mimmi stop!" Zac turned to his parents. "I am not cheating on Evie with Mimmi. We found out something four months ago that is hard for me to admit. But I really do care about her."

Zac looked at his hurt sister standing in the doorway. He turned back to face his parents.

"Mimmi is my twin sister."

And with that, I finish chapter one. I had this idea in my head for the longest time. This is my first fanfiction and I hope you liked it. Chapter two is on its way. Thanks for reading!
