Zac tried to avoid his parents the following day. He knew that they would have loads of questions for him, but he really didn't have the energy to come up with a lie to try and put them off of his trail. All he wanted to do was to focus on the new threat that has the entire Southern mermaid pod worried. What was he going to do with the water dragon? He had no idea what to do with something like that. It wasn't like he could use the trident to stop it. It had been completely destroyed after the fight in the merman chamber when Mimmi used it to bring him back to life and restore his powers back to him. Even if there was some way to bring back the trident, Zac was pretty sure that the mermaid counsel wouldn't be happy with that. After all, they had just returned to Mako.

Sighing, Zac paced around his bungalow. It just didn't seem fair to him. First he was turned into a merman, then he had to deal with the whole trident situation, now this. It was exhausting for him. He just wanted to finish school with his friends and learn about his merfolk history. He really didn't feel like cramming a huge water dragon into his already hectic schedule.

Zac stopped pacing and sat down on his couch, putting his head in his hands. This was starting to give him a headache. And it wasn't like he could talk to many people about his situation. Sure, the mermaids were really helpful, but sometimes, he just needed to talk to…

…Talk to another merman.

That, that is what was bothering him the most. He only met one other merman and most of the times, Erik was less than helpful. He really didn't know much about his true identity. He tried asking Mimmi, but she didn't know much. She did give him the knowledge that his birth father was a merman. That is the only way he and Mimmi could have been born. Like his sister told him, when a mermaid and a merman mates, they could get either a boy or a girl or sometimes, in their case, both.

That was why it was so shocking to everyone when they found out that Mimmi was his twin. That means that his birth mother, Nerissa, had to have broken a huge rule by being with a merman. When he was born, she knew that she would have to give him up. She couldn't have swam in with a baby boy and girl and everything would have been fine. She broke thousands of years of tradition.

It would have been fine with just Mimmi though. The pod wouldn't have batted an eye when she was born. Every other mermaid in their pod was born under the power of the full moon. And mermen were born by a land girl and a merman. He was… different. There wasn't someone like him that he knew. And this made it really hard to relate to someone.

Groaning, he pushed off the couch and looked out his window. The sea was calling him again, and he really wanted to listen to it. He always felt better after a swim. It calmed him down and made him forget about all of his problems. He could just be free and enjoy life without having to deal with anything.

But his parents would have asked him where he was. He had no excuse this time. All of his friends were busy. Cam had a doctor's appointment and his doctor was, you guessed it, his dad. Evie was going to see her grandmother for the weekend. His parents knew about this because her dad asked Zac to water their plants while they were gone. Carly and David were both working at the café, Mimmi was working at the Marine Park, Ondina was teaching the younger mermaids and he didn't know Weilan that well.

He could start his history assignment that was due in two days…

Or he could play video games until his friends were home. Option two seemed like a better idea.

Hours had passed before he knew it. He must have fallen asleep because he was awoken by a soft knock on his door.

Blinking sleep out of his eyes, he mumbled "Come in."

A smiling brunette opened the door. Mimmi was home from work.

"Oh hey sis. What's up?" Zac asked, sitting up on the couch that he must have fallen asleep on. His video game was still playing on his TV.

"Hello." Mimmi greeted cheerfully as she walked inside. Zac reached over and grabbed the remote, shutting off his video game.

"How was work?" Zac asked.

"It was… interesting." She said, sitting down on the couch next to her brother.

Mimmi recalled the events that happened that day with some of her coworkers going to Mako to see if they could find the water dragon. Zac seemed very concerned of Chris being in the moon pool with Ondina, but Mimmi assured him that with the help of Weilan, they were able to convince Chris and his friend Karl, that the water dragon was actually a water sprout. Zac laughed at the clever idea his friends came up with to put the Marine Park workers off of their trail.

"Anyways, do you want to go for a swim? They reef looks beautiful today. Besides, the fresh air will do you good." His sister said, noticing that Zac was gazing out the window at the sea.

Zac nodded and stood up from the couch. He put his hand out and helped Mimmi up. Together, they raced out of the bungalow and ran off the dock, diving into the crisp blue water. Little did they know, Zac's parents were watching them through the window.

After they broke through the water, Zac and Mimmi both sighed in relief as they felt their transformation took place. Zac looked down at his dark blue tail and smiled. He looked over at his twin, who was looking at a shell on the ocean floor. Her golden-orange tail sparkled from the sunlight. Her dark brown hair floated gracefully around her.

Zac flicked his tail and swam up beside her. She showed him the shell that she was looking at and smiled. She placed the shell back on the sandy floor and motioned her brother to come with her. With a flick of their tails, they were off.

Using their super speed, the twins sped through the water, leaving the human world behind them.

Zac and Mimmi reached the moon pool within a matter of minutes. Zac, who was slightly faster than his sister, surfaced first. He took a deep breath of air and shook his wet hair out of his eyes. He turned and waited for his sister to appear.

"No fair! You totally cut me off at the edge of the reef!" Mimmi exclaimed when she surfaced in the moon pool. She too brushed a lock of hair away from her eyes and then glared at her brother.

Zac smirked at her comment. "I did not. You just can't face the fact that I am faster than you even though you have been swimming with your tail your entire life. I won fair and square."

Mimmi huffed and swam to the edge of the pool, her back turned to her brother as she pouted.

"Someone's a sore loser." Zac said laughing as he flicked water at his sister with his tail.

Mimmi let out a squeak as the water hit her back. Turning sharply around, she used her tail to splash her brother back. This escalated quickly. Pretty soon, the son and daughter of Nerissa were having a full out water fight. Using their skilled powers, the two merfolks were conjuring huge water balls to drop on each other.

Mimmi, who has had more practice with her powers, soon outnumbered her brother. She caused a huge water ball to drop on her brothers head, forcing him under the water.

Once he emerged, he was gasping for air.

"Fine. I surrender. You win." Zac said, breathing hard.

"Yes! I am victorious! Bow down to me all creatures of the deep!" Mimmi yelled, thrusting both of her arms up in the air in a winner stance.

Zac snorted at his sister's action. "You win this time little sis, but I will beat you one day. Just mark my words."

Mimmi smiled. "In your dreams." She teased, sticking out her tongue.

Zac let loose a laugh. His sister was right. This was exactly what he needed. He didn't have to worry about anything. He could just relax.

Mimmi picked up his nervous energy that still remained with him though.

"Hey, are you okay? You seem… off." She asked, swimming up next to him.

She placed a wet hand on his shoulder. Zac glanced at her hand and then looked into her eyes. He really didn't want to turn the relaxing mood sour. But he knew Mimmi. Once she knew that something was bothering him, she wouldn't let it go. It was one of the things he loved and hated about her. She was always willing to help him, even if he didn't want any help.

Seeing his face full of worry, Mimmi threw her arms and hugged her brother. Zac tensed up at the slightest, but soon returned the hug. He buried his nose in Mimmi's salty hair and held her tight. He knew that she would do anything in her power to try and help him.

After a few moments, he pulled back and looked at his sister in the eyes. She was really worried about him. She motioned to the sand outside of the moon pool and swam to the side. She grabbed the edge and pulled herself up and out of the water. She dragged her tail over the sand and began to dry her tail. Zac watched as she turned back into a land girl. She was wearing a black tank top with jeans and black flats. Her brown hair lay gracefully on her shoulders.

Mimmi patted the sand, a motion for Zac to follow her. Sighing, Zac pulled himself out of the moon pool and pulled himself next to his sister. He reached his hand out and began to dry off his tail. Using her own powers, Mimmi helped her brother dry off. Soon he was completely dry and was sitting on the sand wearing an old t-shirt, some basketball shorts and a pair of Converse.

Mimmi leaned onto her brother and placed her head on his shoulder. Zac slung an arm around her and sighed.

"Will you please tell me what is bothering you? Maybe I could try and help. If it's about the water dragon, I …"

"It's not just about the water dragon." Zac interrupted his sister. Mimmi sat back and looked at her brother.

"Then what else could be bothering you? Is it Evie?" Mimmi asked.

Zac rolled his eyes. "No sis, Evie and I are totally fine."

"Then what is it?"

Zac flopped down on the sand and stared up at the sky through the hole in the volcano. He sighed deeply. Mimmi poked his side with a finger.

"Hello? Anyone home?"

Zac slapped her hand away lightly and turned his head to look at his sister. She raised her eyebrows and waited for his explanation.

Zac sighed again and put his hand over his eyes.

"It's just, I wish I knew more about my merman history. I feel so useless sometimes. I don't have a moon ring and I wish that I had something to help you guys defeat the water dragon. I don't know what kind of skills I possess. It's just hard sometimes, you know?"

Mimmi was taken aback for a moment. She had no clue that her brother felt so troubled with this whole merman stuff. She really didn't know how she would help him, but she knew that she had to try.

"Hey, maybe I can ask Veridia if she knows anything. It really wouldn't hurt to ask." Mimmi suggested. With his eyes still under his hand, Zac smiled.

"Thanks sis. I would really like that."

Mimmi smiled too.

Zac's shorts pocket buzzed. He sat up and pulled his phone out of his pocket to see that he had a new message. Unlocking his phone, he looked at it. It was a message from his father.

Dad: Home. Now.

Zac showed the message to Mimmi who was not standing over his shoulder.

Zac: I'll be home soon.

Zac sent the message and looked at his sister.

"I better go. I don't want to make them mad." He told her. Mimmi nodded.

Zac stood up and dove into the water. Mimmi remained on land still. She was going to sit there and think for a little while longer.

Zac surfaced and turned to his sister. "Mimmi?"

The brunette looked at her brother.

"Thanks for today. I really enjoyed it." Zac said with a small smile.

Mimmi matched the smile. "Anytime."

Zac nodded and dove under the water, making the short voyage to land.

Mimmi sat back on her hands and looked up at the sky. She took a deep breath and closed her eyes, thinking of what to do next.

Sibling bonding! Can you just picture Zac and Mimmi having a huge water fight in the moon pool? Zac is taking the whole merman thing pretty hard and Mimmi is there to help him get through it. Rob seemed to be a little upset in his message. I wonder why?

Thanks for all the love and support! xoxo
