As promised, one original chapter that purely has David and Reanna.

H20 Just Add Water Fanfic | Mermaid Magic | David's Birthday

The first thing David knew when he woke up was a freezing sensation splashing all over his body; he gasped awake, jumping into a sitting position. He was also fully aware that familiar amused giggles had let loose near the bed, but not too close. "Reah." He grumbled, not only recognising the giggle, but also what she had done to wake him up. She stole his fun; throwing a bucket of ice water over him to wake him up. She didn't even give him a chance to get out of bed before the water came, she played dirty.

"Yes, brother dear." Reanna replied, trying to contain the laugher in her by pursing her lips. It was about time he got a taste of his own medicine, and doing it on today especially was the top of the cake.

David looked up to her, seeing that she had now placed aside the wet bucket, "I'll get you back for this." He promised, in a playful way.

She just smirked back, not at all threatened, "Not with water you won't." She was sure, especially with their parents in the house.

"Oh, sister." He began, a smirk of his own playing on his face, "I know many other ways to get you back – none of them including water."

That made her smirk die down just a little, but then she just smiled regularly again. She went over to the little sofa chair in the corner of his room, grabbed the pillow of it before chucking it into his face. David wasn't quick enough to catch it, so it did indeed hit him in the face.

"You have half an hour." Reanna told him, looking happy, pointing her finger at him sternly. She had the day all mapped out, all since the beginning of last week. She hoped it would be amazing for him, but she knew he'd love the day anyway. "And if you're not down by the time is up, you'll figure out first hand just how much alike we are in the pranking business."

David was still in his bed, water slowly dripping from his hair, he definitely needed a shower now. Still sitting, he bent his upper body forwards, imitating a bow, "Yes, your fishy-highness." He mocked.

She rolled her eyes, "Just get ready, birthday boy." She said just before retreating from his room, leaving him there to contemplate what she might actually have planned for them. David idly wondered where their parents were – usually on birthdays, they were home for maybe a couple of hours before going out together on their own. What nice parents they were, (sarcastically speaking).

With a more awakened sigh, he stripped the covers off his bed before padding over to his own bathroom. Just like Reanna, he also gained a private bathroom after moving to the Gold Coast.

He knew he had to get ready quickly, not only before he didn't exactly want to experience what his sister might have gained from him over the years when it came to pranking. But also, because of over the week he's been deeply excited about what she might have planned for them. Today was all about spending time with each other; no friends, no parents (when they were left alone) and no problems. He always did something special for her birthday too, and he couldn't wait until that day came either, it wasn't too long until her birthday was going to come around.

Birthdays between them were the best days of the year for them, and he believed it would always stay like that.

~ 8 ~

Reanna had made her way downstairs, already being washed and dressed, ready for the day ahead. She continued making David's special birthday breakfast which consisted of sausages, bacon, eggs, beans and home-made fries. Just like herself, they made a birthday breakfast for each other before getting on with the day – hers consisted of several David-made pancakes with berries, both made into a fruity sauce and as a natural fruit. As you can tell, Reanna always went with the healthier option, even on her birthday.

Just as she began to plate up the breakfast, making a plate for herself too – she did have to admit, his breakfast did look mighty good – David entered the kitchen, his hair still wet but it now gave off a rhubarb scent because of the shampoo he uses. "Ooh, that smells good." He complimented, sniffing deeply, looking over his sister's shoulder to see his special breakfast being plated up. His stomach rumbled hungrily.

"You're just in time." Reanna replied, pouring the last piece of food onto the plates, the beans. She placed the pot back on the stove, filling it carefully with hot water (making sure she didn't come into contact with it) so the bean sauce won't stick to the pot itself. She picked up David's plate before passing it to him, grabbing her own before sitting down at the table with him. He sat opposite her, immediately digging in with the cutlery he placed down only a moment ago.

After the first few bites, David swallowed, looking up at his sister, "Mom and Dad are out aren't they?" He hadn't heard any other movement this morning since he woke up half-an-hour ago by Reanna. He wasn't surprised that they weren't home, but he couldn't help but feel a little saddened that both his dad hadn't taken the day off and that his mother couldn't have just stayed home. They haven't even wished him a 'Happy Birthday' yet.

Reanna nodded, humming as she did, swallowing her own piece of food. "Dad had to go to work as usual and I think mom mentioned something about getting you a present." Making it the assumption that she hadn't got one for him yet.

David gave a scoff, shaking his head, looking down at his food, "Wow, it's like they get worse and worse each year." He commented.

Reanna's eyes suddenly lit up, "Speaking of presents." She said, wanting to make him feel better and forget about their parents. She got out of her chair in a hurry before running upstairs, making thumping sounds against the stair case steps as she went. David paused in his eating, watching the area of where she disappeared with a curious look.

About a minute later Reanna was coming back down the stairs and she appeared back into the kitchen/dining room. "Here." She said, passing her brother a small box wrapped in blue wrapping paper.

"Ooh." David's own eyes lit up, excited. It was a present. "What is it?" Forgetting that, she wouldn't actually tell him.

Reanna rolled her eyes, "Just open it." She replied in an exasperated tone, anticipation bubbling in her veins. She really, really hoped he'd like it. She hadn't really known what to get him, but the moment she saw this, it was like she knew.

When he opened the present, his eyes widened as he took a sight of the object inside. It was a shell, but not just any shell, a very rare one only found in the deepest parts of the ocean surrounding Australia. "Is this a-" Not being able to find the words to say the name. It was incredible.

"-a Cribrarula Cribraria." Reanna nodded, finishing his sentence for him. As soon as she found it, research had been done for hours until she found its name. She knew her brother loved anything to do with the sea, just like her, and this shell was rare enough to be immensely special.

The shell was about the size of his palm; and the shell itself was shiny and clean, the white dots on the outside and inside were a pearly white, while the background colour on the outside of the shell almost looked like a tanned skin color.

He forgot momentarily that his sister was a mermaid when he was about to ask her how she got it; mermaids could obviously go very deep by the looks of it. Without another word, he went over to her side and pulled her into the tightest hug, almost cutting off her airways. "Thank you so much." He mumbled into her hair.

Reanna chuckled with relief but also breathlessly since the air to her lungs was getting slightly cut off, but really, she was just glad that he loved it. "Your welcome."

It was about ten minutes later that both siblings finished their breakfasts and while David washed up the plates and stuff, Reanna went to place his new shell on his desk, hidden away just in case their parents were to come home while they weren't there.

"So, what are we doing today?" David asked his sister as she returned to the kitchen, carrying a bag and throwing it on the dining table. He was just finishing up the drying of the plates, knowing that Reanna couldn't do anything like that anymore because of the no water touching her skin issue. They would have to remember to get her some kind of washing up gloves, just in case either of their parents insist that she does some washing up one night while he's at work.

"Well, first-" She started, grabbing a couple of water bottles from the fridge and throwing them into the bag where she filled it to the brim with towels and the food she had packed previously before making breakfast. "-I'm taking you swimming." She grinned, looking up at him.

David raised his eyebrows in confusion, finishing up the last plate before putting it back into the cupboard, "But you can't go to the pools anymore." He stated dumbly.

Reanna let out a groan of frustration, why did her brother become suddenly dumb? "Okay, let me rephrase that." She began, putting her hands on her hips, looking up at him with a cocked eyebrow of her own. "I'm taking you diving into the deep sea, so you better go get your diving gear." She finished with a sweet smile.

David started to grin, "Really?" He hadn't said it out loud, but he had been just a little envious that she could actually swim in the ocean deep enough to see many different animals in the sea. He had silently hoped that one day she'd take him with her at some point.

"Yes." She gave him a nod, before pointing towards the stairs like she had done back when she woke him up. "So you better hurry up and get ready before mom gets back and ruins our plans." Knowing her, she'd come home and insist on them staying inside all day. Reanna snorted in her mind, 'Fat chance of that happening'.

"Go, now." She ordered, seeing him still standing there. Suddenly a giddy smile crossed his lips before he dashed upstairs, giving Reanna the impression that this birthday was probably going to be his most favourite.

~ 8 ~

Several hours later, David finally found himself in the ocean, swimming next to his sister in his scuba geer. He's been diving before, otherwise, he wouldn't of have all this equipment with him if he didn't, but, this time, it was different. Reanna had taken him to what she referred to 'the part of the ocean she's seen so far, that has so many species bound together'. And she was right; all of the fish, stingrays, even dolphins and more were swimming together, not even a fight in sight. Everyone was swimming in harmony it seemed.

Just as he swam over one of the larger reefs, Reanna swam up to him, her fin flipping up and down to propel her forwards. She tapped his shoulder, gaining his attention – he looked over at her, seeing her pointing towards the surface. He nodded slowly, the water giving him resistance to do so. She grabbed his arm and started pulling him up with her slowly, knowing that you couldn't go fast when you're trying to reach the surface.

As they broke the surface, David climbed back into the fishing boat their dad owned. They decided to borrow it for the day, it wasn't like the guy was going to use it anytime soon.

"That was amazing." He stated as soon as the breathing mask was off his face, he ran a hand through his dripping hair, laughing in delight.

Reanna chuckled, liking the enthusiasm. "I know, right?"

David shook his head, "I can't believe you do this every day." He had to admit again that he was indeed just a little jealous, but in reality, he knew the gift of being a 'merman' in his case wouldn't be very good. He worked too much with water and honestly, he was fine with the scuba gear and having a mermaid for a sister.

He knew one thing, though; this has been the best birthday so far.

David got out a couple of biscuits from his sister's bag and passed one to her, and leaving two for himself. She was hanging on from the side of the boat, keeping part of her upper body above water as they ate their snacks.

As they finished eating, Reanna spoke up again. "You ready to go for another round?" Brushing off the crumbs from her lips.

David nodded, looking pleased. "Sure, where to next?" It was about three o'clock by now, so it wouldn't be too long until darkness started to fall on the horizon. He couldn't believe that they had been swimming for nearly 5 hours now, it seemed unbelievable. But time fly's when you're having way too much fun.

Reanna sent him a grin, "Meet me at Mako." She requested, before plunging back into the ocean, disappearing and leaving him alone in the middle of the ocean.

~ 8 ~

And he did, he was just about to park the fishing boat onto shore when he saw Reanna standing on land, back into her human form. It didn't look like she had been waiting long, she probably took the long way knowing he would take a lot longer that she would getting to Mako.

"You took your time didn't you." She teased him, watching as got out of the boat, pulling it further into shore with a heave.

David just chuckled, "You know, not all of us have a super-fast tail that can swim a hundred miles per hour."

Reanna ignored that, "So, ready for round two?" She questioned, grinning. She looked behind herself, they were in the exact spot where she and the girls had come onto shore back when they turned into mermaids.

"More than ready." He nodded back, throwing his backpack over his shoulder. Just before he did start heading over to Mako Island, he had dried himself and got changed into some dry clothing since something told him that they wouldn't be going swimming again for this moment.

"Good." Reah nodded approvingly. Grabbing the small bag she had brought with them that had a couple bottles of water in it. She grabbed his arm, dragging him along with her. Luckily he had dried himself, otherwise she would have just turned into a fish when she touched him. "Come on." She coerced. David started to follow her close behind, silently wondering where they were going in particular.

~ 8 ~

"Oh, this is cool." David couldn't help but exclaim as he took in the surroundings. Reanna had brought him into a cave, but not only that, he was currently standing right beside the moon-pool. He looked up, realising that they were standing in a volcano. A dead one, but still a volcano. The water itself looked amazing, a serene blue color with a shimmer to it.

"That's what we thought too the moment we found it." Reanna nodded, agreeing with him. "So far this is the only place we can really connect to when it comes to, well, what happened to us."

"Has Lewis been able to figure anything else out?" He questioned, remembering that his sister had mentioned before that the guy was a science whizz. Lewis was trying to figure out more about how/why they were transformed into, mermaid hybrids so to speak.

"No," Reah shook her head, but not sadly, just a tiny bit relieved, "But I'm not bothered, though," She spoke honestly, getting him to turn to her. She just shrugged, "As far as I can see it – yeah, there's been a few downfalls – but I think of it as a gift because, if we hadn't grown the tails that next morning. I probably wouldn't have become friends with them, I would have still been my shy shelf without any self-confidence in me."

David smiled before pulling her into a big hug, almost like this mornings one. "Thank you, Reah. It's the best birthday I could ever ask for." He said to her. Today really had been the best day they've had together in a long time. She really was the best little sister anyone could ask for, and he hoped that she felt the same way about him being her older brother.

Reanna returned the hug, leaning into him. She grinned, "Now you have to try and top this for my birthday next month." Wondering how he was going to beat swimming deep in the ocean.

David cringed over her shoulder, not sure how to top this perfect day. "Ah, well, I'm sure I'll think of something." He promised. He really would have to think really hard on that one.

Note: Well, I hope you guys like this chapter, a full-on original without an episode getting in the way. Next chapter will be the first part to 'Moon Spell'. Which may also be up later tonight; but at 6, I am needed somewhere else so I won't get it done until later on.

3RD CHAPTER TODAY! YEY! LoL
