I gasped for air as I ran trying not to be late for potions. My dainty feet ached because they weren't used to working so hard. Dumbledore has granted me permission to use the prefect bathrooms, so I could be in my natural form in peace.

I quietly slid into the classroom and into a seat next to Harry. He was reading the book filled with secret spells and potion tips. I make sure I share it with him. Slughorn adores us. Oh yeah, we rock.

"Today we are going to learn how to make a Parneky Potion, so please open your books to page twenty," Slughorn walked in as soon as I sat down and Harry flipped to page twenty.

"Now who can tell me what a Parneky Potion does to the drinker?" Professor Slughorn asked. Hermione's hand shot up in the air. Big surprise there.

"Yes, Hermione?"

"The drinker of a Parneky Potion is given the ability to breath underwater for a certain amount of time depending on the amount that was drunk," my eyes widened and I locked eyes with Ron, Harry, and Hermione. This is not good for me. I looked at Draco and he smirked at me.

"You may begin by following the instructions in your books. I will be observing you as usual," the classroom began to make potions so Harry and I began to work in our cauldrons. I added the ingredients one by one by following the scribbles in the margins rather than the actual text. I was about half way through the steps when I pulled out the next ingredient. Fish. The text said to slice, but the handwriting said to cube. Half the class was slicing their fish and it was just too much for me. The last thing I remember from potions is Harry catching me as I fainted.

OoOoO

I woke up in the hospital wing. Except my tail was out in the open. This was dangerous. I looked around. I was the only person in the spacious room right now, but you never know if someone is going to walk in. I tried to will my legs to form and succeeded just in time. Two boys were carrying an injured girl. Except, it was Harry and Ron supporting Ginny.

"What happened to her?" I sat up and regretted it as my head began to pound.

"She fell off her broom, but not from too high up," Ron said. He looked really worried and upset. So did Harry, of course.

Madame Pomfrey walked in from her supply room and rushed over to tend to Ginny. I slowly stood up and walked over to where the unconscious Weasley lay. I couldn't help it, so I sang. A very dangerous thing for a Siren to do. The song was calm and melodic and Ginny's wounds began to heal. Madame Pomfrey, Harry, and Ron began to fall asleep to my healing lullaby.

"Sleep in peace dear child,

Rest your head dear child,

It'll be okay dear child,

Sleep in peace dear child," the song even made the birds outside fall silent to listen. Nature itself paused to hear my voice. And Dumbledore later told me that even the loud first years stopped what they were doing when they heard the song echoing through the castle. That's mermaid magic for you. Except it was mermaid magic that nearly brought me to my downfall.

Sorry, folks, it's just a filler! It really needed to end on this confusing cliffy. At least I updated it!
