As always, I really appreciate the reviews! Big hug to everyone who reviewed *hugs* I just forgot to mention, if you have any questions (about this story or just something random), feel free to ask me. Don't worry, I don't bite!

I got a B on my textile materials test this week (my test was one of the good ones because most of the tests were bad, almost all Ds and Fs) so I decided to do this chapter today out of happiness.

Dyson's POV

Girls have finally agreed to help me clean up the path that leads to the cave entrance on Ooha'oma. Whenever I go there, I always end up hurt and it really became annoying to hide grass cuts and bruises from my parents. I dunno what I would say if they asked me where I've got them.

I gathered some needed equipment - including the grass cutter that I borrowed from May's dad - and headed towards the island with everything on my motorboat. Thank God, my boat was big enough that everything fit into it and I haven't sank yet, which was a good thing. As I came close to the beach, I noticed three female figures - two tall and one short - standing there with their arms crossed. One of them waved at me and I could see her smiling. Yup, those were the girls. We agreed that they'll wait for me there and - for once - they sticked to the agreement. And I had something to show them too.

As I parked my boat - as far away from water as possible so the girls do not get wet, of course - the girls came to me and helped me carry the equipment out. But before that, I got a big, delicious kiss from May. That girl liked me, I just knew it!

"How did you manage to get here without getting hurt?" I asked. Whenever I go to that cave, I always get those injuries, but there was no sign of even the smallest cut on the girls' bodies. I found it pretty strange.

"We swam and dried off here", May explained. Okay, it was not strange anymore. I felt stupid asking something like that.

The only sound I could product was the quiet: "Oh", before I suggested that we start our island 'makeover'. May just smiled at me as I kissed her cheek and she slightly blushed. Destiny rolled her eyes and ordered us to start working, while Melissa just laughed at the whole situation.

- H2O -

We were almost half way done and everyone was pretty tired, so we took a little break and went back to my boat to get some food. Since we knew this makeover would take lots of time, we agreed to pack some food and supplies for the day. Everyone out of four of us added something - whether it was a drink or a sandwich or some kind of a snack - so we had a pretty nice amount of food with us.

Finishing our lunch, we got back to the makeover so we could finish it before the night falls. It was already 5 pm and everyone was pretty tired - including myself. But what caught my attention was May's constant yawning - ever since we got to the island, I noticed giant black bags under her eyes: she probably hasn't slept very much. When I asked her if she's okay and even offered to do her work so she can go home and take some rest, she just said she's fine and that we should continue. I mean, I know she never slept for more than six hours, but she almost always seemed fine about it until today. I guess I was just being too overprotective.

"Dyson, we can't go there near the waterfall, we might get wet", Destiny spoke, shaking me out of my thoughts. I looked up and saw a huge waterfall spreading down half the volcanic mountain. Remember when I said I had something to show to the girls? Well, now was the right time for it.

"Don't you worry, ladies. The Dyson here has the cure for your water vulnerability", I spoke proudly.

May just frowned. "The Dyson?"

"The Dyson", I repeated and smirked. "Remember when I needed samples from you for a test? Well-"

Melissa cut me off. "How could I forget? You got slapped by May and she got angry at you."

I let out a slight, fake smile, remembering the painful memory I wanted to leave behind as I continued: "Well anyway, I made something to make you waterproof. I finally managed to finish it!"

Destiny and Melissa yelled: "Really?" and seemed terribly happy about it, while May simply rolled her eyes.

"We said no more tests or else you know what will happen."

I approached her and put my hands on her shoulders. "This is not a test. This is just… Trying out." Even though it was kind of a test, that was the best possible excuse I could think of at the moment. May just rolled her eyes and muttered something under her breath, while I returned back to my boat and brought a small, blue 'deodorant', which was actually my 'invention'.

"Spray this on yourself", I said. Seeing that no one was willing to do it first, Destiny rolled her eyes and took the spray, spraying her arms and legs with it. She went to the small river the waterfall was making and put her fingers in it, then sat on the rock in case she transforms. But when nothing happened in about ten seconds, the girls all screamed in joy and sprayed themselves with my invention.

"This better not hurt me", May said harshly as she was the last one to spray herself, emptying my entire deodorant bottle.

"It will not, trust me." I was so sure it will not. Damn, I should've been more sure!

Destiny's POV

I was kinda thrilled that Dyson's spray worked, but was also a bit worried since it was Dyson's work, after all. He is a pretty good scientist for a fifteen-year old, but he also screws up as many times as he succeeds. I remember once in seventh grade, we had a chemistry project and he designed some liquid that is said to cure pimples instantly, but when he tested it on himself, it gave him a terrible rash that lasted for about two weeks. Even picturing that makes me shake in fear.

But since it was almost two years ago, I thought he improved. I mean, he liked Melissa, May and me - especially May - and he would never give anything to us before making sure it was safe. I just knew he would never do anything to hurt us so a little trust would be the least he expects.

After spraying with that thing, the girls and I successfully worked around the waterfall and managed to cut all the grass around it without growing tails when getting wet. It was already 6 pm and everyone was pretty tired, so we decided to go back home. As we headed to the beach, I felt something itching my face, legs and arms. Soon it became bright red and itched a lot. The girls had the same symptoms too.

"Dyson, what the hell is this?" I asked, thinking it was that spray he gave us. He was the only one unaffected and it seemed weird.

He just stared at me blankly, observing the rash. "It's probably the poison ivy. I think I saw it in the woods."

"But why aren't you affected?" May asked.

"You three were near the waterfall. I was not. Don't worry, just put some ice over it once you get home and everything will be okay. Trust me." I wish I could.

- H2O -

It's already been a week since the guys and I did a makeover on Ooha'oma. Now we even have a bridge in the forest over a river in case we go there for a walk or get moonstruck and someone already is there and sees us - we should thank Melissa and May for that since they convinced their dads to make it. The only thing we had to do was to post it there.

The grass was neatly cut and was cut-proof. We even made a path so we don't have to go through the whole forest in search for the cave entrance. Speaking of which, we cut the grass around it too so it looks prettier. We did a makeover in the cave too; just made the wall a bit prettier by removing all the ugly parts and cleaning off the small sand particles that were on the ground. We found a big rock in the forest and put it above the cave entrance so no one can enter it or even think there's something like a cave under it if they go there. Pretty smart, huh? It was my idea, actually. The only thing that sucked about the whole makeover was that poison ivy thing, but it was worth it. And Dyson's invention helped a lot, too.

And here I was now, meeting with the girls in the park. We thought about having a nice afternoon walk, but all our plans fell into water after seeing the scene a few meters away from us - Illene and Therese each holding a plastic bag full of water balloons, throwing said balloons onto each other like a group of five-year olds.

"I cannot believe this! They're always ruining everything", May groaned as she, Melissa and I sat on the bench and watched the playful twosome.

"Remember when we used to throw those at each other when we were five?" I glanced at May, who just smiled and nodded. I remember those times. Those were actually the good times and I'd gladly return to them. At least I haven't known those two bitches back then and I wasn't a fish. What can I tell you? Good times!

"I always used to beat my sister at it", Melissa said, taking a deep breath. "I hope they won't come near us."

Suddenly, Dyson appeared near us and kissed May's cheek. I have no idea when he get there since I haven't even seen him coming. Quiet guy he was, I gotta tell you. I noticed him taking the bottle of his waterproofing spray and proudly showing it to us.

"I did it! I'm a genius!" Okay, what the hell did he do now? I just had to ask him and I already kinda had a guess.

"Let me guess… You found out you're an alien left by his real family on Earth so Earthlings can adopt it and wonder what a computer-minded child they've adopted?"

He just rolled his eyes. "No. I managed to increase the capacity of this spray so from now on even if you put only a single, little drop of it, your whole body'll be waterproof."

The girls and I gave him awed looks. I gotta admit, he really impressed me. For some 15-year old wannabe scientist, he did really good. And believe it or not, there was more.

"And I managed to come up with a name: Aqua spray!"

Melissa laughed, May simply gave him a surprised look and I rolled my eyes. Aqua spray? How more dumb can it sound? Someone like him should come up with a more scientific sounding name. Maybe even with Latin name. But I mean, really? Aqua spray?

"What? That's how I called it." He probably noticed us being surprised and shocked about such a lame name for someone like him so he wanted to find the most acceptable excuse he could think of. "It's lame, I know, but it's the best I could think of. And I was too excited about it so I haven't really had time to think about the name."

He sprayed May's hand and took a small bottle of water from his back pocket. I wonder how big those pockets actually were when everything seemed to fit in them. He then opened the bottle and splashed May's other hand. She wanted to run away to the ocean, but he grabbed her hand.

"Again you don't trust me?" When he asked her this, he seemed really hurt that she didn't trust him. Poor baby! But thank god, she thought of a perfect excuse, even though it sounded a bit fake when she said it. She's usually a pretty good liar, except when she's with Dyson.

"No, of course I trust you. It's just my instinct. I'm used to running away from the water." Oh, please! You should've thought of something better to say. But anyway, it actually worked. Twenty seconds have passed and nothing happened. "You really did it!"

May put her arms around Dyson, pulling him into a passionate kiss. They stayed that way until Dyson stepped back and gently ran his finger down her cheek.

"I'll leave you guys with this so you can spray yourself. I gotta go buy myself something to eat, I still haven't eaten anything." He gave May one quick kiss and handed her the Aqua spray, after which he left to find the store.

Noticing Illene and Therese approaching us, I took the spray right out of May's hand and sprayed my arms a bit. Melissa and May did the same and soon the already small bottle was empty.

"Hi, gals", Illene said as she and Therese now stood right beside the bench. May immediately sat back down, seeing as they were holding the water balloons.

"Wanna have some fun?" Therese asked, holding up a big red water balloon. Even seeing it gave me chills. Even though I had Aqua spray on me, I still didn't want to get wet. What if it loses its power after a couple of minutes? Dyson haven't said anything about that.

"Don't you dare", Melissa said in a threatening tone. Illene just Therese just frowned.

"What? This? It's quite pretty, isn't it?"

I noticed May putting her hand behind her back and waving it. The balloon exploded in Therese's hand, making her whole body wet. I would expect some of the water to be on us too - since it was the balloon explosion - but I guess May took care of it. She, Melissa and I burst into uncontrollable laughter.

"It's not funny!" Illene yelled angrily, raising her hand in which she held a blue balloon. I could see tiny drops of water running over its plastic surface and it was enough for me to gulp… But it was also enough for Melissa to have fun.

Like May, she put her hand behind her back and did her stop-sign thingy, freezing the balloon's surface that touched Illene's hand, freezing it on it along. Illene waved her hand - trying to throw the balloon at us - but instead she let out a scream.

"It's frozen! My hand's frozen!" She yelled. I have to admit, she sounded kinda scared. Illene immediately went over to her to check on her hand, realizing it really was frozen.

But the fun wasn't over yet. May waved her hand again, making the balloon explode on both of them. The three of us burst into laughter again, while they screamed, annoyed. What made me laugh even more was the fact that when all her makeup was washed away by the water, Illene's makeupless face looked like that of a boy. Now I realize why she puts makeup on - to look like an actual woman! A pretty bad move since there was barely a difference, but hey - who can judge her? I would've done the same with a face like that. Even though I do wear makeup, I do it only because I like it. In my mermaid form I'm without makeup and I myself think I look fine.

"What the hell?" I heard the bitches yelling in disgust. Rolling my eyes, I got up and went over to a nearby tree, leaning against it and observing the sky. I was sick of everything and just wanted to be left alone. Have I asked too much?

Melissa's POV

A good move to leave, Destiny. A really good one. Going away from these two bitches was a smart idea. I was just about to g after her, but I felt someone grabbing my hand. Looking back, I saw Therese pulling me back.

"You're not going anywhere", she said in a playful tone. She reached out for her bag, taking out another water balloon. She was about to throw it at me, but I hit her hand, causing her to drop it.

But that - of course - didn't stop her from taking another one and looking and laughing at me sinisterly. I told her a couple of times not to do that or I might hurt her, but she just kept on laughing. I was just about to raise my hand to freeze the balloon and her hand with it, when she suddenly put her hand down and leaned her head closer to me, squinting her eyes to observe me carefully.

"What the hell? Maybe you should go home instead of being here. It seems you've got too much sun." While saying that, she actually sounded worried. But what was she talking about? I've got too much sun? How? I don't get it.

I heard Illene telling something similar to May and when I turned back to look at my friend, my mouth went wide and I put my hand over it in shock. May's whole face, arms, legs and neck were red - dark red - like she had some sort of a rash or something. Looking at her, I felt my body itching so I itched my hand, but widened my eyes at the sight of the very same redness happening to me. And it itched. It itched harder by every second.

I noticed May scratching herself too, before turning to me and ending up shocked just as I was. The two of us looked at Destiny, who was also scratching, but her 'rash' seemed to be a bit worse than ours. She returned us the glance as May went over to her, taking her hand and leading her to where I stood.

Without even questioning anything, we already had a pretty good idea of what caused all of this. "Dyson!" Poison ivy, like hell!

Holding our hands, we headed towards the store Dyson went to, only to find him a few meters away from it. He held a hot dog in one hand and a cell phone in the other.

"So, you know, mom, you just have to press - "

May cut him off by taking the phone out of his hand. "He'll call you back, Mrs. Zachary." And with that she hung up, returning the cell phone to its owner.

"Wow, you look angry", Dyson said, observing our red skin.

"What the hell did you do to us?" May asked in an angry tone.

He backed a step away. "Okay, listen. We can work this out. I just…"

"You just what? Tell us what the hell did you do to us!" I shrieked.

"Nothing", was the only, simple reply he could give. I just couldn't let him get away with this. The girls neither, but I... I was the most stubborn one.

"Nothing? Then What the hell is this?" I pointed to my red, itchy skin. "What did you put in that damned spray?"

"Oh, that", he spoke nervously - smiling - and backed away for another step, but we took a few steps to stand closer to him.

"I can make him blood evaporate", Destiny said, angered by the whole situation.

"Not before I freeze it", I raised my hand like Destiny did. What is it with people these days? Can't they just admit it when they're wrong?

May did the same. "I always wanted to see how it's like when person near you has a heart attack. I guess now is the right time to find out since my power allows it. It will be quick, don't worry. At least I heard it is."

Dyson's smile faded away and was replaced by a scared expression. I guess our words had a great effect on him. "Okay, okay, listen. You probably have some bad reaction to the ingredients I used, but - "

May cut him off. "What ingredients? You used out skin! Our DNA!"

"Well that, yeah." He continued. "Anyway, it should pass in couple of hours. At least that's how long the spray was supposed to work."

The girls and I glanced at each other. Should we trust him or not? I mean, Dyson had his moments, but he would never do anything to hurt us in any possible - and impossible - way. At least not on purpose. But he had to be taught a lesson.

"I dunno. He doesn't sound pretty convincing to me. Maybe he's just saying this so he can get away with everything", Destiny said.

I nodded. "I agree. How do we know he's actually telling the truth?"

"Why don't we mix our powers instead of using them separately? Then maybe he learns his lesson", May smirked.

"We can do that", I agreed. Destiny nodded in agreement.

Dyson made a step back again and cleared his throat. He was obviously scared of us. He had a pretty good reason to be. "I'd never lie to you. Ever!" He looked into May's eyes and tried to smile, but her serious expression made him erase that smile immediately.

"You're so dead!" May threatened then turned to Des and I and the three of us ran towards the pier, jumping into the ocean and heading towards Ooha'oma.

May's POV

The girls and I pretty quickly made it to the moon pool. We got up and as Destiny dried us off, we instantly took our cell phones to check out our face condition. Just as I thought, it was as bad as the one on arms and legs. But the rash became a bit easier to handle and the redness slightly started disappearing.

Damn, how I hate Dyson for this! I knew from the very beginning this was a bad idea, but who listens to me anyway? And I quite sure he knew from the very beginning this was now from the poison ivy, but his brilliant invention. Don't get me wrong - I really love my boyfriend and care deeply for him, but at times he can be pretty stupid.

"I hope it'll disappear soon", Melissa whined as she sat on the stone ground and hugged her legs with her arms. She took a lock of her hair and nervously curled it with her finger over and over again that it became annoying.

Destiny checked her looks in her cell phone's screen again and growled. "Your boyfriend will so pay for this, May. I even cooperated by giving him a hair sample voluntarily and what does he do in return? Gives me a rash!"

"I told him not to mix science and magic, but he just had to be a smartass!" I rolled my eyes at the very thought of him and closed them to calm myself down. But it was pretty hard to get call because I kept seeing Dyson holding his Aqua spray in my head. I should hunt him down like an animal and rip his head off so he doesn't forget what he did to us. And those two bitches just had to see us like that. When school starts again, we're screwed!

A sound of something landing in the cave shook me out of my thoughts. Opening my eyes, I saw Dyson getting up and observing the three of us with a guilty look on his face. I think he was pretty aware of what he did and something told me he was here to apologize.

"Let me tell you I'm really sorry for everything that happened to you guys. It really wasn't intentional." Ooh, I was right. He did come to apologize. Too bad we were not in the mood of accepting apologies. At least I was not.

"And what if something bad happened? We could've died!" Melissa shrieked.

Dyson looked down, ashamed. "I know. I'm sorry."

Yup, he was sorry, but apologizing won't cure the rash we had at the moment, now will it? And there was something else I wanted to confirm if it was true. "Dyson, did you know it was not the poison ivy that gave us a rash during the last week? Were you aware that it was this thing of yours?"

"I…" he muttered, unable to finish his sentence. I heard him gulping and taking a deep breath. "I…"

"You knew? Why haven't you said anything instead of being persistent with that spray?" Destiny snapped.

"I wanted to be right." Okay, now we're being honest and talking. "Even though both May and Mrs. Tanner told me not to mix science and magic, I wanted to prove them wrong. Science in most cases succeeds and I just wanted it to succeed this time too. I guess I just… Refused to believe in magic. I knew it was not the poison ivy all along, so I decided to upgrade Aqua test and gave you an upgraded version of it today, thinking it would work properly this time. But instead… It did this. I lied that it was poison ivy since it seemed appropriate because it was there, but poison ivy reactions are different than this. But look at the bright side: at least you girls know you're not allergic to poison ivy!"

My eyes went wide at the sound of what he said. Look at the bright side? He knew it was his spray that caused everything and tried to correct himself by making it worse? He used the girls and I as his guinea pigs? This just couldn't go without consequences. I had to do something to make him pay for what he did. "You really are a moron!"

He cleared his throat. "Even the best scientists make mistakes. And you know the old phrase: people learn from their mistakes."

'People learn from their mistakes?' This really angered me. He just admitted he used us as guinea pigs and wanted to use us more like that since people learn from their mistakes. Furious, I raised my hand and levitated a small water ball out of the moon pool and threw it hard at Dyson, making him fall back and hit the wall with his back.

"I can't believe you just said that! I don't think I'll be able to trust you anymore!" I yelled. I felt a single tear running down my cheek and quickly wiped it away.

"I'm really sorry, guys. I promise it'll never happen again. I promise, you can trust me."

Melissa shook her head. "I don't think we can."

Dyson sighed and gulped. "Please, give me another chance to prove to you I'll treat you with respect this time. Please. No more tests, no more anything. I swear!"

Destiny looked at Melissa and me. "Should we trust him?"

That was a pretty good question. After all he did, do we have a reason to trust him? He could disappoint us again by doing some more tests without us even knowing what he's doing. I thought he was a nice guy, but with his actions he proved different. He did try to help, but did it the wrong way. Should I really forget everything and give him another chance?

"I think we should." Melissa broke the uncomfortable silence.

I slightly nodded. "Okay, I also think we should." I noticed him smiling again. He probably thought it was going to be easy. "But, no more tests in any kind of way. If you repeat this - I promise - not only I will dump you, but will make this ocean swallow you."

Destiny smirked. "Did we make ourselves clear?"

Dyson nodded and sighed in relief. "You did. You have my word of not repeating this ever again."

- H2O -

I know this is similar to the original series, but it is H2O after all. Dyson just had to screw up somehow and I had no idea how so this is the first that came to mind, but the poison ivy fact was kinda in place. Please review about the actual chapter, but please don't say mean things. I don't want to be disappointed in my readers. If you won't review, I won't update anymore.
