Mimmi raced through the water towards the grotto. Ondina was not happy that she was going out so late, saying that they needed their rest and that whatever Zac had to stay could wait until the morning. She promised her that she would be home soon and that Ondina should just go to sleep.

Mimmi passed a school of fish that swam lazily through the dark water. Passing the coral reef, she sped through the opening in the rocks that let to Rita's moon pool.

Her head broke through the water.

"Zac?" Mimmi called, blinking the water out of her eyes. He rounded the corner and smiled when he saw her.

"Good, you're here. I found something."

Mimmi nodded and grabbed hold of the rocky ledge. With a great difficulty, she hosted herself out of the water and onto the gravel floor. She groaned as her golden-orange tail still hung in the water. She didn't get far enough the first time and she huffed in frustration.

Zac smiled in amusement. "I would help you but…" he gestured to himself.

Mimmi glared at him. Then, with a flick of her hand, she sent a jet of water towards his direction, hitting him straight in his chest.

Zac frowned at her. "Thanks," he muttered miserably. His transformation overtook him as he fell to the floor, his blue tail slapping it hard.

Now, both the twins were in their original form. Mimmi hauled herself out of the water and settled next to her brother, who stuck out his tongue at her. She laughed and used her powers to conjure up a water ball from the water on her tail. Zac did the same, preparing for the attack that he knew was going to happen. They waited until their legs reappeared before standing up, the massive balls of water sill floating above their outstretched hands.

"Don't do it sis," Zac threatened, shifting the water in front of him like a shield.

"Do what?" Mimmi questioned, batting her eyelashes to try and look innocent.

"You may have won the last water fight but I swear that I will win this one."

Mimmi smiled wickedly. "We'll see about that."

They both poised themselves in a battles stance, but before they could do anything, both of their water balls flew back into the moon pool.

Weilan stood by the entrance. "Nope. It is far too late to be behaving like children. Now if you would please leave so I can get some sleep, it would be much appreciated," she huffed. "Mimmi I thought you already retired to the moon pool for the night. What ON EARTH ARE YOU DOING HERE?" her voice rose, showing the teens that she was tired and did not want to be messed with.

"I- I…um… Zac…uh…" She started.

Zac cut her off with a wave of his hand. "I was returning Mimmi's purse when the book…the book!" he yelled. Zac rushed past Weilan into the main part of the grotto. The book was still there.

He stopped abruptly and waited for the two girls. They looked at in in shock.

Mimmi was the first to recover. "No. That's impossible. I left it with Veridia. I swear," She looked up frantically at her brother. "This shouldn't be happening. Why is it here?"

Zac shrugged. "I don't know but there is writing in it now."

Mimmi's eyes went as big as saucers. She dashed over to the table and grabbed the book, her dark blue eyes skimming the writing. "What on earth does this mean?" she mumbled to herself. She flipped through it as she tried to find more of the writing. She sat down on the bench. Weilan and Zac soon joined her.

"I recognize this writing…" Mimmi whispered. She closed her eyes to try and remember. Zac and Weilan waited patiently. If they could find out who wrote that in the book, then maybe they could figure out who it belongs to.

"Uggg!" Mimmi groaned in frustration, throwing the book back onto the table. "It's on the tip of my tongue! I know this writing, but why can't remember? It's like there is a block on my mind!" She jumped off the couch and started to pace around the room. "I am so sick and tired of being in the dark! We don't know how to defeat the water dragon yet and the full moon is tomorrow, and now this stupid book shows up!" She stopped pacing and threw her hands up into the air. "I'm done!"

"We can always use Turn the Tide," Zac suggested, referring to the Eastern Pod's self -defense that he recently mastered with the help of Weilan. He was also trying to calm down his sisters frustration.

Mimmi glared at him, her hands coming to her sides in fists. "The mermaid council already said that it wouldn't work!" She shot back at him.

Weilan looked at Zac with a mixture of fear and confusion. No one had really seen Mimmi get this upset before. She was normally the peacemaker in difficult situations. He just shook his head, indicating that she just needed time and rest.

"I'm going home. I can't think anymore," Mimmi said, her voice still dripping with bitterness and frustration. She walked out of the grotto. Zac and Weilan heard a splash and they knew she was gone.

"She is just under a lot of pressure right now. Just give her space," Zac said, trying to reassure Weilan. "I'm going to head home and I suggest you also get some sleep." He added, patting her leg.

Weilan nodded and snuggled under the blankets that they were sitting on. She kicked Zac when she couldn't stretch out anymore.

Zac chuckled as he stood up from the bench. "I guess that's my que to leave," he joked. Weilan mumbled something in her pillow as a response. "I'll see you tomorrow in the moon pool."

Zac exited the grotto and walked upstairs, not wanting to disturb Weilan anymore. He exited Rita's house through the main entrance. He knew that his parents were still suspicious of him and they wouldn't think twice with him walking home the normal way. Plus he needed to clear his head. The fresh air will do him some good.

Zac entered his bungalow and flopped down on his bed. He gazed up at his ceiling and sighed. Tomorrow would be a big day. He knew that Weilan and his plan would be going against everyone he cared about. But he had the power to get rid of the water dragon for good and he was going to take it. He would protect those he loved and would gladly take any punishment that was thrown at him. That would then show that he didn't mean any harm, and the mermaids wouldn't have to be afraid of him anymore.

While he was lost in thought, his was absentmindedly making little water balls from the glass of water on his end table. He made them float over to him, holding them high in the air before dropping them into his open mouth.

Little did he know, he didn't shut the door completely when he entered his room. The nigh wind blew it ajar without a creek. Rob was walking by to make sure that the boat was secure to the dock when he saw his son laying on his bed. He had to do a double take when he saw Zac make a hand gesture and a small ball of water rose from the glass on his bedside table.

Robs eyes grew wide in disbelief. He blinked a few time, trying to clear his vision. Nope. The water ball was still hovering over the glass. Zac flicked his hand again, and the ball shot straight into his mouth. He swallowed, as he was still unaware that his dad was watching him.

He cleared his throat and began to sit up. Rob jumped away from the door. He didn't want his son to know that he saw… whatever that was. Rob crossed around the house and peaked through the window.

Zac was standing in the middle of the room now. Rob saw him take a deep breath before swinging his arms around in a circle and pushing the air in front of him out. He was practicing the movements for Turn the Tide. There was nothing that he was pushing back, but a little practice couldn't hurt.

He repeated the movements a few more times before nodding to himself. He was happy with his progress. He sat down on his couch and proceeded to pick up his science book. He leafed through it before settling down on a page and beginning to read.

Rob dashed up to the main house. His wife was sitting on the couch flipping through a cooking magazine. She looked up, only to be greeted by the fear in Rob's eyes.

"Rob?" she questioned, setting the magazine aside.

Rob took a deep breath before sitting next to his wife, telling her everything he just saw.

A few moments later, Lauren was silent as she absorbed the news.

"So he just… controlled the water?" she asked, still in shock.

Rob nodded. "Completely. It looked to him like it was as easy as writing his name. No effort… no concentration..."

Lauren was silent. "But how?"

Rob shrugged. "I have no idea, but I think it has something to do with his sister."

Lauren was taken aback. "Mimmi? Do you really think that she knows what is happening?"

"They are always spending time together, and she is his twin. If she doesn't know, than no one else does…" Rob stated.

Lauren fell back against the couch cushions. "It would make so much sense," she muttered. Rob furrowed his eyebrows in confusion. "The reason why we think that Zac is hiding something from us. He has powers somehow!"

Rob raised an eyebrow. "Over water?"

Lauren hit him with the back of her hand. "You just saw your son drink water from midair. Are you really doubting the fact that he could maybe not be…" her voice dropped to a whisper. "Normal?"

Rob got off the couch. "I don't know what he is, but I bet that Principal Santos and her nieces know a lot more than they are letting on. I mean how convenient is it that his sister lives with his school principal, and whenever something weird happens, they are all involved." Rob looked at his wife who nodded.

"What do we tell Zac then?" She asked in a hushed tone.

Rob shook his head. "Nothing. We can't let him know that we figured out… everything."

Come on Zac! You had one job!

So Rob and Lauren think that they have everything figured out. Well boy are they wrong!

Next chapter is a spin off chapter! YAY!

Also to answer Princess of Mako, my favorite mermaid is the one and only Mimmi! Sirena is a close second.
