AN: I meant to get this up sooner. But It's up now. I hope you like it.

"Susan I wont let you do this!" Mrs. Pevensie said when her daughter arrived home after the term with a note from the teacher that said that Susan was no longer on the swim team.

"I can do what a I want." Susan cried. "I'm not a little kid and I just don't want to swim anymore okay?"

"But Susan, sweetie, you love swimming."

"No I don't!" Susan insisted she backed into a table with a large water-filled vase on it. A few drops landed on her arm. "Darn it!" She screamed, racing into her room and slamming the door behind her.

Peter stood in the hallway watching them fight, wondering what in the world had caused Susan to quit. She really did love swimming. At school she'd won prizes for it. At home she actually begged Peter to help her train so that she didn't lose her speed. But now she didn't care about it? What was up with that?

Of course there was the obvious answer that she was on drugs or something but somehow Peter didn't think that was it. It was something else, something she wasn't telling him. And he was going to find out what it was.

"Susan?" He knocked on her door.

"Go away." She called.

"Can I come in?" He asked ignoring what she had just said.

"No, I told you to go away." Inside the room, Susan laid sprawled out on the floor glaring at her tail. Stupid thing! It made life so hard!

"Su..." His voice was full of concern.

"What part of go away don't you understand?" Susan shouted wishing she'd had the time to lock the door before her tail had formed. What if he walked in and saw her like this? By Aslan, please don't let him come in here. She thought to herself.

"Whoa...She's grumpy." Edmund said as he walked by. "What's wrong with her?"

"Maybe she's moody because she got kicked of the swim team." Lucy said coming up behind them eating a gram cracker.

"She didn't get kicked off, she quit." Edmund told her.

"What? Why?"

"She won't tell anyone." Edmund shrugged.

"Weird." Lucy scrunched up her face in confusion.

Hours later, Susan came out of her room. She was feeling thirsty. She tiptoed quietly into the kitchen. After that outburst she wasn't sure she wanted to meet up with anyone from her family right now. Especially not Peter.

But just as Susan poured herself a glass of water (being careful to let none of it actually touch her skin.) Peter arrived in the kitchen.

"Susan, we need to talk." He said firmly.

Susan tried to ignore him. She sighed and grabbed a plastic straw for her water (If she drank it without one some might escape and land on her neck.) as she tried to casually walk away.

Peter reached out and grabbed her wrist. Now what?

"What do you want?" Susan asked.

"I want to know what's wrong with you lately." Peter said, not wasting any time beating around the bush. "You've been acting really weird."

"I have not." Susan quickly lied, feeling very stupid.

"Let's recap shall we? You kicked me in the face, was found in a neighbors back yard at an ungodly hour, run like the wind whenever you come near water, and you quit the swim team." Peter shook his head. "I'm starting to see a pattern of weird events centered around water."

"It's nothing, really." Susan insisted. "I just don't want to swim anymore that all. Honest."

"I can't believe you're lying to my face." Peter glared at her. "We promised to tell each other everything."

"I know..." For a moment she wanted to tell him the truth but deep down she knew she couldn't. "I mean, I'm not lying..."

"Susan!" He was getting fed up fast. "Just tell me what's going on."

Suddenly a new realization dawned on her. He was one to talk! He'd been keeping a secret from her for years. The little known fact that his last name was Burke! The fact that he wasn't even really her brother. And he didn't think she had a right to know? Now Susan didn't feel half as guilty about keeping her mermaid tail a secret.

"We promised, Su." He said. "Remember?"

"Yeah, I remember, Peter Burke!" She snapped before she could stop herself.

He looked like he'd been punched in the stomach. "How did you find out?"

"Box in the attic." Susan said weakly.

"How long have you known?" He asked holding back tears.

"I found out right before we left to go to Mako Island." She confessed.

Peter gulped. "I...I really didn't want you to know about that...I didn't want anyone to know..."

"What about telling each other everything?" Susan asked with more bitterness than even she knew she had in her.

"I thought you wouldn't like me anymore..." Peter said sadly. Susan couldn't help but notice for once he didn't look old and over protective, he looked small and helpless. "I thought that if any of you ever found out you wouldn't treat me the same way."

"That's not giving me a lot of credit." Susan told him.

"I know..." Peter said. "But you don't know how hard it is."

"Do you know anything about your real parents?" Susan asked.

Peter nodded. "My father's name was Jacob Burke he was very rich. My Mother's name was Elise Burke. They married very young and didn't want some kid bothering them all the time. After I was born they didn't even name me. They let the maid pick it. A few months later, they dumped me in an orphanage and moved to an even richer part of town."

Susan felt sick. Poor thing. His parents were horrible human beings. They didn't even want their own son. What kind of monsters were they?

"Mom was already pregnant with you when she adopted me. She went to the orphanage to volunteer..." Peter was still trying not to cry. "And Mum told me that I grabbed onto her leg and wouldn't let go. And that's how I met mum and dad."

"And they took you in." Susan already knew that part.

"Please...don't ever...call me Peter Burke again..." He was fairly begging. "That's not even my name...I'm Peter Pevensie...I'll always be...Peter Pevensie."

"I know, I'm sorry." Susan said. "I promise never to call you that again if..."

"If what..."

"If you promise...if you promise..." She was going to tell him. She had to. "...not to call me fish girl."

"Why would I call you fish girl?" Peter didn't understand what in the world she was talking about.

Susan took a deep breath and tilted her water glass so that the water fell on her arm. She counted back in her head. In a few moments, he'd know everything. Would she regret this? Maybe. But he needed to know.

Suddenly she fell to the ground, a long fish tail where her legs had been moments ago. Susan waited a moment before looking up to see his reaction.

Peter's mouth dropped open. "Oh my..."

"Hand me a towel?" She asked. "I'll turn back to normal once I'm dry."

He handed her a dish towel that hung by the stove. His eyes were wide and he was obviously in shock. "How?"

"I think it had something to do with that pool of water on Mako." Susan told him. I don't know...But I really think it had something to do with the moon too."

Peter smiled. "So that's why you wont go near water."

"Well, what did you think it was?" Susan asked.

"I couldn't even guess." He kept staring at her. She made a very pretty mermaid he had to admit that. Even prettier than the Narnian ones.

"Stop looking at me like that..." Susan started blushing. "...It's creepy."

"Sorry." Peter helped her back up as her legs re-formed and her tail vanished.

Susan happened to glance at a drop of water on the counter top that was about to land on the floor. With out thinking she waved her hand at it. The water froze in mid air. How had she done that? "Peter, re-fill the glass would you?" She pointed to the glass of water on the counter.

He did so. She twisted her wrist in the glass's direction and it started to boil. Peter walked over to it and touched it with his pinky finger. "Hot!" he gasped blowing on the now-turning red finger.

Then Susan waved her hand again and the water started to swirl out of the glass. Just as it was about to hit her, she froze it in mid air.

"I didn't know Mermaids could do that." Peter said sounding somewhere between impressed and very freaked out.

"Me neither." Susan told him, her eyes as wide as humanly possible.

"Are you going to tell Edmund and Lucy?" Peter asked her.

Susan wasn't sure. "I don't know, but for now let's not tell them anything. It's our secret got it?"

"Got it."

AN: Review? I'd love to hear what you think.
