AN: It's short, I know but I just wanted to make sure I got the full moon thing in by the second chapter. it's kinda importaint to the storyline. The next one might be longer.

Being a mermaid was downright weird. Sometimes, Susan would sit in the tub gaping at the tail that hung over it. Her thoughts would be so far away that sometimes she's spend hours there. After all, it did feel good to be in the water. And as she rarely went near water now-a-days in fear that someone would see her fish tail, she to make up for the loss. She figured she would have to quit the school swim team. But she still hadn't decided how to tell her parents. She certainly wasn't going to tell them she was mermaid. That was mad talk. They'd see her differently if she told them. They'd try to protect her from crazy scientist people or something. She'd never get to be a normal girl again.

"Susan!" Edmund yelled from outside the bathroom. "You've been in there for five hours, I need to pee!"

With a heavy sigh, Susan got out of the tub, dried herself off, and watched her fin turn into legs again. Why me? She thought sadly. But she didn't dare cry. What if a tear drop made her fin appear again?

Time passed and Susan spent most of it on her own wondering how she would-no, could-keep the secret once she started school. What if a girl tripped and spilled a glass of water on her? What if a teacher ordered her to get touch water? What if...

Her mind was so full of what ifs that she didn't have time for her siblings anymore. She stopped reading Lucy stories at night. She never helped Edmund study math or history anymore. And she spent less time with Peter too. Sometimes he would want to talk to her and she wouldn't even be able to pay attention. Her mind was always on something else.

One time when he sat next to her with glass of water, he laughed at something causing a drop to escape from the glass and land on Susan's arm. Susan let out a gasp and raced into the bathroom and locked herself in. Peter knocked on the door to see if she was alright but all she said was, "I'm fine, go away."

But the worse thing for Susan was that she was completely unaware of a danger mermaids must protect themselves against at all costs. The full moon. She didn't think anything of looking out her window at the big silvery mirror in the sky. She'd done it many times before with nothing to worry about. But this time was different. She gazed at it, it was calling her to the water. She wouldn't stay cooped up in a stuffy house when the cool water and lovely sweet night air were offering themselves to her.

Her bedroom door was open and Peter happened to walk by just as Susan was lifting the window's latch.

"What are you doing?" Peter asked. "We never open the windows at night."

"I'm going out." She said calmly, her eyes still on the full moon.

"What?" Peter cried. "Where?"

"Out." She repeated.

"I know that." He moaned. "Out where?"

"I don't know." Susan said still not looking at him.

"Then get back in here." Peter said as she leaned her head out.

"No." She sighed in a distant dreamy voice. "I'm going." She started to climb out the window.

"The heck you are!" It wasn't a very kingly thing to say but at the moment it could be forgiven all things considered. He reached out, grabbed her feet and pulled.

"Let go." She said in that same calm voice.

"No!" He pulled harder. "What's wrong with you?"

She turned and looked at him for a moment but her expression gave him chills. It was like she wasn't even sure who she was speaking with. Her eyes had this freakish distance about them and her pupils were huge.

Without thinking, she kicked at his face. And uttered another calm, "Let go."

When He didn't, she kicked harder. This time he let go to put his hand to his eye. That was going to leave a mark. She managed to slip away now.

"Goodbye." She said softly as she raced out of the yard. She was out. Where to go now?

After wandering about aimlessly, Susan finally came to a neighbor's back yard. There was a huge pool there and the moon was reflected in it. She jumped in with out a care and her tail formed. She didn't worry about getting caught. Under the grip of the full moon she didn't worry about anything. She wasn't even worried about Peter back home sitting with a raw steak to his eye wondering why she'd kicked him. She just swam and swam around in laps until she felt sleepy. Then she eased herself in to one of the lounge chairs by the pool. Even when she was dry, the tail stayed. But Susan didn't care about that now.

In the morning, the tail was gone and there was just a shivering, normal, Susan Pevensie asleep on the lounge chair.

The Neighbor was to say the least, surprised at seeing the elder Pevensie girl asleep in her back yard. But she was good friends with Mrs. Pevensie (They were in some kind of book club together) and didn't yell at her. She simply woke her up and asked why she was there.

"I don't know." Susan gasped. The last thing she could remember was looking at the full moon. She didn't remember anything else. Not swimming in the pool, not talking with Peter, not kicking Peter in the face, not any of it.

"You look scared dear." The neighbor said kindly. "Come inside and warm up. I just made some tea. I'll call your mother and tell her you're safe and well. Goodness dearie, were you here all night?"

"I don't remember." Susan mumbled.

"Susan sweetheart, you weren't...drinking were you?" The Neighbor asked. "I know about peer pressure and all that but dear, it's really not..."

"I wasn't drinking." Susan said. At least she didn't think so. Was this really happening? This had to be some kind of weird dream.

Her mother and father weren't home. They thought Susan was in her bed that morning and had already gone. Mrs. Pevensie was food shopping with Lucy and Mr. Pevensie was at work.

Only Peter and Edmund were home.

"Well can one of you come and get your sister?" The neighbor asked over the phone. "She seems dazed and I don't feel right sending her back by herself."

"I'll come." Peter grumped. He was still mad at her for kicking him but it was still his duty to come and get her.

When he arrived, Susan let out a cry. There was a huge dark bruise around Peter's left eye.

"What happened?" Susan asked him. "Where you in a fight?"

"Su!" Peter barked as he walked her home. "Don't you remember? You gave me this little present last night."

"I what?" Susan gasped feeling sick to her stomach. "What else happened last night?"

"You don't remember?"

"No." Susan looked at Peter's eye again. "I'm so sorry, does it hurt? Are you okay? Why did I...?"

"I don't want to talk about it." Peter said swinging the door to their house open. "Just get in."

"I'm so sorry, Peter." Susan insisted. "I didn't mean to. You believe me right?"

"Sure." He shrugged. He'd forgive her in time but not right now.
