Warnings: there is discussion of a past abusive relationship and a flashback of abuse.

Ash felt as though his powers were working on their own; time seemed to slow down when his ex-girlfriend came into the room. He and Lara had grown up best friends and were happy together as a couple for a year, but before Ash became a merman things became bad for him and in the end he had to get a restraining order against her. His family were furious that she hadn't been sent to jail for the way she had treated Ash, but her father had friends in high places. The sight of Lara made Ash's heart hammer in his chest.

Lara came close to Ash and kissed him even though he tried to turn away to stop her. His reaction didn't seem to faze her though, she just grinned at him in the way that still haunted him.

"W-what are you-"

"Doing here? Well Linda found out about us and contacted me. She told me everything Ash", Lara leaned even closer to Ash making him wish he could get away. "But I don't care that you're a freak I still love you".

Lara's words made Ash's eyes squeeze shut in pain. His eyes snapped back open in surprise though at Linda's reaction.

"Hey! Don't call him that!"

"Why not? He is a freak".

"Do you have any idea how much Ash is worth, that he could change everything?" Linda yelled furiously.

Lara rolled her eyes, "Whatever".

Linda pursed her lips and Ash could tell she was doing a lot to stop yelling at Lara again. "This isn't a good time Lara, I was about to start the experiments". That made Ash panic even more but Linda spoke before he could.

"But you said if I helped you I could have Ash again", Lara said with a pout and grabbed Ash possessively making him wince in pain.

"I said you can have him when I'm not doing experiments, now please go unless you would rather I make you leave". Lara glared at Denman and left after kissing Ash again. "I'm sorry about her Ash-"

"Why do you want her here? You're not really going to let her have me are you?" Ash said unable to keep the fear out of his voice.

Linda smirked at Ash, "She was an important part of your life and I bet she knows things that even your little gang doesn't know".

Ash's blood ran cold and Linda laughed cruelly. Linda was right. There was a time when Ash trusted Lara when he loved her, he had told her things that he hadn't told anyone. Ash knew that she wouldn't hesitate to spill his secrets to Linda, especially if she was given him in return and that thought terrified him. Linda grabbed Ash's chin again to gain his attention.

"You never answered my question".

Though it hurt Ash so much he made himself tell Linda why he was so afraid of water.

4 months into Ash's relationship with Lara...

Ash jumped when the doorbell rang, he put the book he was reading down and got up to answer it as everyone else was out. Ash's heart raced in fear when he saw that it was Lara, they had a huge fight the other day. She was so angry that she hadn't been invited to Ash's family dinner, but his mother had said that he and his siblings couldn't bring their partners as it was meant to be just for their family. Ash had apologized and tried to explain this to Lara but she wouldn't believe him and kept shouting that Ash was embarrassed to be seen with her when he was with his family. The fight had gotten so bad that she actually hit him hard enough that he fell to the floor.

They had stared at each other in shock until Lara fuelled by her fury wouldn't stop hitting Ash. He had tried to block her but it was hard to do because Ash didn't want to hurt Lara. Ash didn't know how long she had beaten him but he had never been so relieved when she stormed out of his house. Ash had wanted to tell his family what had happened so badly, especially when they questioned him about his injuries but he was too afraid to. Afraid that they wouldn't believe him. So in the end he just said it was bullies.

Seeing Lara in front of him looking just as angry as she was that night paralysed Ash with fear. When Ash snapped back to reality he tried to stop her coming in but she shoved him backwards and he nearly fell again but caught himself using the door.

"Lara please go".

"No we need to talk!" Ash closed the door and as soon as he did Lara grabbed his arms hard enough to bruise, "So are you going to make it up to me?"

Feeling a bit courageous Ash managed to glare at Lara, "After what you did to me, I... I can't do this anymore. I'm sorry but we're over".

Lara gaped at Ash and the fury in Lara's eyes scared Ash and he tried to get out of his house but her grip on him tightened even more. She dragged Ash to the garden despite his struggles. She threw him in the pool and when he came up for air she pushed him back under the water and wouldn't let him back up. Ash panicked and did everything he could to try and get back up but Lara's grip was too strong. Just when Ash thought he was going to die Lara let go and Ash sprung back up spluttering and coughing. Lara grabbed him again and Ash thought for one terrifying moment that she was going to do it again but she pulled him close and whispered.

"If you ever try to break up with me again, I won't let you come back up for air next time. Understood?" When Ash didn't answer she made to put him under the water again scaring Ash.

"I understand", Ash croaked.

"Good", Lara said with a smile. She dragged Ash out of the water and kissed him fiercely.

Now...

Ash hadn't realized he had been crying until Linda wiped his tears away making him flinch again.

"I'm so sorry Ash I had no idea".

Ash gave her a confused look, "I thought you did your research".

"That was something Lara left out".

Ash was even more confused when he could see genuine remorse and sadness in Linda's eyes. Linda seemed to care about him despite what she had done to him and what she was planning to put him through. Why would she care about him? One of the people in white coughed awkwardly making Ash jump. He had been so scared by Lara's appearance that he had completely forgotten they were there.

"Shall we move it? Everything is ready in the lab for it", the woman said.

Ash's eyes widened in fear and his heart hurt at being referred to as 'it'. He tried to plead one more time, "You know this is wrong, you may not want to believe it but you know it is. Please don't do this".

Again Ash could see remorse in Linda's eyes but it was soon replaced by coldness, "Like I said, you're not really human so there is nothing wrong about doing this at all. Move it to the lab".

Despair overtook Ash as he was being moved to the lab and he saw tools lying on a table next to him that looked as though they came straight out of a horror movie. Linda grinned terrifyingly at Ash.

"Let's begin".

Lewis and Cleo were alone in the living room. Zane and Rikki had gone upstairs to call some of their friends for help, while Emma had gone outside to do some research on Denman. Lewis didn't want to leave her alone but she had insisted and Lewis knew her well enough to know that she needed the time alone. He and Cleo were on their phones doing their own research.

Lewis had tried several times to talk to Cleo but had failed each time. Cleo seemed to be taking the whole mermen reveal very well and didn't act any different around him and Zane, apart from times when he would catch her staring at him with the same awe that she had when looking at his tail. Lewis was still scared that she would change her mind. Lewis jumped when Cleo put her arm around him.

"What's wrong?"

"N-nothing". Cleo raised a disbelieving eyebrow at him causing Lewis to sigh. "I just... are you really okay with me being a merman?"

Cleo moved closer to Lewis and hugged him, "Of course I am. You're my best friend, this doesn't change that".

Lewis felt his heart sink at the words 'best friend', but at the same time he felt hope that Cleo still cared for him, "Really?"

"Yes. I know you're scared especially with what's happening to Ash right now, but I promise you, I would never expose you or Zane and Ash. I mean sure Zane can be soooo annoying", Cleo said making Lewis laugh. "But I couldn't do that to him or Ash, and certainly not you".

Lewis smiled happily and hugged Cleo tightly, "Thank you that means so much to me". Cleo hugged back just as tightly and they stayed that way for a long time until Zane and Rikki came in making them spring apart.

Rikki laughed, "Sorry didn't mean to interrupt you love birds", she said making Lewis blush and exchange an awkward look with Cleo.

"My friends have agreed to help us", Zane said excitedly.

"Who are they?" Cleo asked.

Zane grinned, "Magnus Bane and his boyfriend Alec Lightwood".

For those who have seen or read Shadowhunters I hope you like this crossover. For those who haven't Magnus and Alec are a canon couple from Shadowhunters, I recommend reading the books, watching the series and movie :)
