I DON'T OWN MAKO MERMAIDS.

Also, special thanks to Izi Wilson for submitting the title :)

Zac was running home. Last night… last night had to be the worst possible full moon he ever had. The events that happened in the merman chamber were constantly replaying in his head, as if his own brain was mocking him. He tried desperately to push them off, but…

"Nerissa had a son… a son that could share visions with her daughter. A connection made possible only through blood" Rita explained to Mimmi and everyone else in the chamber after Veridia had imposed the danger of 'The Son of Nerissa' and Mimmi had demanded answers about her mother. Rita looked at Zac, who was standing in front of the pedestal with a confused look, while Mimmi looked shocked.

"You are that son, Zac. You've never been a land boy. You were always a merman". When she said those words, Zac's world came crushing down. Rita's words felt like a billion daggers had been stuck in his chest; his breathing became heavy as he looked a Mimmi, who was looking at him with a startled face. Time seemed to slow down while he tried to process the information. What happened next was a blur to him: he barely noticed Veridia threatening to kill him and Ondina and Mimmi jumping in his defense. He barely acknowledged that their act had cast them out of the Mako Pod.

However, there was one thing Zac noticed:

"You're my brother"

… It was impossible. The more the memory repeated itself, the more Zac wanted to cry and arrive home sooner. He had refused to believe the mermaids; he needed to know it from his parents. The people who raised him. Maybe all of this was just a misunderstanding…

…Right?

Before he knew it, Zac had reached his home. It was early, barely 6:30 or 7:00 am, but he needed to talk with his parents and he prayed that they were awake to get his answers now.

Taking a deep breath he opened the door and was a little relieved that they were both having breakfast.

"Well, you're up early" Rob Blakely said, surprised.

"Zac, is something wrong?" Lauren, his mother, asked concerned after seeing Zac's face.

"Mum, Dad… can we talk?"

"Of course… about what?" Rob asked after exchanging a worried glance to his wife. As the memory of the chamber started again, Zac took another deep breath.

"Please, let them be wrong" he thought before asking:

"Am I… adopted?"

His parent's eyes widened up. Lauren put a hand in her mouth as she looked at Rob, who had somehow kept a stoic expression.

"Zac… do you mind… if you go to your garage? We will be there in a sec" Rob managed to say. And when he said that, Zac knew it. His worst fears had come true. The little hope that he had about the revelation at the chamber being wrong was crushed.

He nodded numbly as he made his way to the garage, and this time the memory of last night started to repeat itself faster than before.

Zac opened the door and sat down on one of the couches. His whole body felt numb. He really wanted to cry, to scream. But he didn't. Instead he waited for his 'parents' to come and give a damn explanation.

"Zac?" Lauren said once she and Rob entered the room and sat down at the opposite couch. Zac didn't look at her.

"Listen, we don't know how you found out. But…" Rob started to say. Zac glanced at him. His 'dad' sighted.

"Yes. You are adopted" he finished saying, his voice breaking at the end. Beside him, Lauren had started to cry. Zac didn't say anything. He stopped looking at Rob, instead focusing his sight in the table in front of him.

"We were going to tell you when you were old enough" Lauren added quietly. Zac's breathing became heavier as tears started to form in the corner of his eyes. He angrily blinked them back.

"Zac, please try to understand…" Lauren started to say, but Rob put his hand on her shoulder while giving her a look that clearly said 'drop it'. He shoots another look at Zac, and it pained him to see his expression. Both him and Lauren got up and left Zac alone.

After they left, Zac got up from his spot. He walked around his room, looking at all the pictures on top of his drawers. Pictures that showed him with his 'family', the one he had thought for seventeen years of his life that they were his real parents. Pictures that showed him with Evie, his girlfriend and his friend Cam; doing normal stuff until he got the tail.

Zac flinched with the last thought. The tail. His actual true form had never included legs. It was always a tail. It hurt him so much to know the truth. Trembling, Zac leaned against the door, his legs shaking as he sank to the ground. The memories started to haunt him again, the cold hard truth from Lauren and Rob adding itself to the cycle.

"Never a land boy"

"Always a merman"

"Son of Nerissa"

"You're my brother"

"You are adopted"

His whole body started to shake. Zac buried his face in his arms while the tears that were threatening to fall earlier appeared again.

He did nothing to stop them this time.
