The news made the entire house became silent. Mimmi closed the door and walked back to sit next to her brother. He gripped her hand as they awaited his parent's reaction.

Rob and Lauren stared at the siblings in shocked. Their faces turned pale as they looked at the children.

Rob broke the silence by laughing.

"Oh Zac, you have always been a jokester. Twins! What a hilarious thought. That's a good one. I mean if you were really related…"

"Rob look at them." Interrupted Lauren, gesturing to the twins who sat with a worried expression on their face.

"Look at them." She repeated. "They look so similar. They have the same bone structure and the same hair color. How did we not notice it before?"

Rob's eyes widened as he saw what his wife was seeing.

Zac looked over at Mimmi, who blushed. They really did look alike. They had a swimmers body (duh) and their bone structures were almost identical. They also had the same chocolate brown hair that Mimmi said their mother had. The only major difference is their eye color. Mimmi had dark blue eyes that often sparkled with delight. Zac had dark brown eyed that had a mischievous glint in them.

"H-How can this be? How did you find each other?" Lauren stammered.

Mimmi took a deep breath and before answering.

"It's true. We are twins. We found out four months ago. We were friends before, but we never knew that we were related."

Lauren closed her eyes before continuing. "Do you know anything about your birth mother?" She asked in a strained voice.

Mimmi sighed. "Yes."

Zac interrupted. "She kept Mimmi and gave me up for adoption."

"So abandoning a baby all alone on the beach is her form of adoption huh?" Lauren turned to Mimmi. "I need to talk to her. Can you give me her address?"

Mimmi looked over at Zac. "I'm sorry, but I can't"

"Why not? What is your mother's name?"

"Nerissa."

"Nerissa what?" said Lauren standing up and growing impatient.

"North." Replied Mimmi after a moment of hesitation.

Zac looked over at her and raised an eyebrow. Mimmi shrugged.

"Well I don't think that Nerissa North would be too busy to talk to the people who raised her son now would she?" Lauren asked firmly. "Where is she now?"

"I don't know." Mimmi croaked as tears began to form in her eyes.

"Of course you know where she is. She's your mother. Now where is she?" Rob yelled, standing up next to his wife.

"I-I…" Mimmi couldn't finish. She put her head in her hands and began to sob. Zac came over and hugged his sister. She turned and sobbed into his chest. He looked at his parents.

"Mimmi doesn't know because no one has seen Nerissa in 13 years. She disappeared one night leaving Mimmi all alone. No one knows what happened to her."

Mimmi sobbed harder.

Realizing her mistake, Lauren went to sooth the crying girl. She rubbed her back and made shushing noises.

"Shhhh. It's okay sweetheart. I'm so sorry." Lauren said.

After a few minutes, Mimmi sobs subsided. She looked up at Lauren.

"I's sorry. It's always been hard to talk about my- our mother." Mimmi wiped her eyes.

Lauren nodded and sat down next to her husband.

"What about your dad?" Rob asked.

Mimmi shook her head. "There was no dad in the picture."

Zac stood back down and gripped Mimmi's hand once again.

"How about we get off the topic of parents. Mimmi, where were you and Zac born?" Rob asked.

"Canada. We were born in Canada. Nerissa took Zac to Australia on our first birthday, June 21st." Rob and Lauren nodded, remembering the day when they found their son. "I came three years later."

"But why? Why would she give up one child and keep the other?" Rob asked.

"I don't know. I was told that where we lived was becoming unsafe. And having two children would have made it very hard for our mother to keep us safe."

"But why Australia?" Lauren looked over at her darling son.

Zac joined the conversation. "I bet she found the perfect people to take care of me." Rob and Lauren grinned.

"So who do you live with now?" questioned Lauren.

"Rita Santos. She knew my mother and she is taking care of me and my best friends Ondina and Sirena."

"Realization crossed Rob's face. "That's why you have been spending so much time at your principles house. I was starting to get worried."

Zac laughed. "No, Rita is like my aunt. Nothing is going on over there. I promise." Mimmi grinned.

"So, are you mad that Zac and I are siblings?" Mimmi asked in a whisper.

Rob and Lauren looked at each other.

"Are you kidding? Lauren and I have always wanted a daughter.

Mimmi smiled as Rob opened his arms. Mimmi got off the couch and ran into his arms. Lauren beckoned Zac to come over. They both joined the hug as the door opened.

Dun. Dun. Dun! CLIFFHANGER! Thanks for reading.
