A/N: Hey! This is the part 2 (or sequel, I suppose...) to my first story H2O: Just Add New Girls Part 1! Please review! I'd love to know what you think of my story. The Part 1 of this series was my first ever fanfiction, so it's not very good. Please note: If you didn't read part 1, part 2 isn't going to make much sense. Be concious of thatb before you read. If you want to challenge yourself to figure it out from here, than knock yourself out.

Chap. 1

I walked to the end of the dock outside my boat house. I stood on the edge and then dove in. I hit the water and sunk down deeper. Just like every other day. The water felt so good.

Ten seconds later, my legs transformed into my beautiful tail. I still never thought I'd get used to the fact that I'm a mermaid. I have saltwater in my blood and in my genes from Will. I was born with the love of the water.

But now I love it more. I'm connected to it. And I'm glad I am.

I swim around a little. Then I feel a pull on my tail. My heart nearly stops. I swim to turn around and give a mental sigh of relief. It's Jessie.

Jessie's like my best friend since birth. She's been there for me forever. Mary and Jessie. It just has a ring to it. And now, we're even more bonded. Bonded by the secret. Bonded at the tail.

I turn my body in the water to look at Jessie. We both smile. It's amazing.

It really, truly is. We don't know why, why it was us or why it happened. We didn't even know how. We want to look for answers. We DO look for answers. But we can't find anything.

I don't know if I want to know… I mean, can't it just be a wonderful mystery of life? I never really admitted this to Jessie. I feel like I should. But I didn't want her wonder to persist because of me.

What the heck?... It's not like me to get like this. Oh well.

But we're not ordinary girls. No one knows that, though. Let's keep it that way.

I swim up behind Mary in the water. We always swim right out front her house and then go out to sea.

The ocean is amazing, full of wonder and beauty and mysteries. I almost can't contain my excitement about it. Being a mermaid is incredible. But I still can't wrap my head around the fact. But it's amazing. I know Mary feels the same way.

Although it's one of the most amazing things that probably ever happened to anyone, it came with challenges. No more swimming in public. Or being wet in public. AT ALL. It's annoying, but it's worth the adventure. We have to keep the secret from everyone. No one can know, or we may end up in a dissection lab. And we all know THAT can't be risked.

I always wonder what would happen if we told certain people. Like Anna or Mary's brother Will. But we don't know who we can trust. And we may never know.

Having Mary alongside me through it is the best part. I wouldn't trade it for anything.

After I nearly gave Mary a heart-attack (which was VERY funny, by the way) we went for a swim. We swam in our special way and then we went into full-on speed swim. The bubbles swirled as our tails flapped in the water.

We came to a slow as we came to one of the reefs. There were colorful fish all around. It was truly beautiful. We both looked to one another, as if a mental telepathy told us when to. I motioned my head towards Mako Island. She nodded and we began to swim in that direction.

We reached the underwater entrance to the moon pool where it all began. We both came up and looked around the cave. We were transformed two weeks ago, so for the past two weeks, we've been trying to figure it out.

We kept looking around the cave, not saying anything. We were just thinking. We had no clue what to think. Finally, Mary spoke up.

"You know, it doesn't matter how long we stare at it. It's not just going to give us answers," she said quietly.

"I know," I conceded. "But there has to be a reason. It didn't just happen out of nothing."

"Well, we don't have to know everything. Can't we just let it be?" she replied. She looked kind of far off, like she was in her own world or something.

I didn't want to argue at a time like this, ESPECIALLY when she was doing her own-little-world thing, so I tried to be rational. "Aren't you just the least bit curious about all of this? Even a little?" I said.

"I guess…" she said uncertainly. "Look, maybe we should come back tomorrow. I'm kind of tired and I have a lot on my mind." She really looked like something was bugging her. I guess she shook off her little world. I tried to see if she would open up.

She sighed and decided to concede. "I've just been kind of hung up on keeping this from Will. I mean, we tell each other everything. It just feels kind of weird that this is an exception…"

I tried to reason with it to make her feel better. "Well, didn't you say he was keeping something from you? Doesn't that feel weird? You shouldn't feel bad. We have to keep this a secret."

"Yeah, I know…" she said. "Let's go. We ought to get back before our families throw a hissy fit."

"You're right," I replied. "Let's go."

We were still seriously wonderstruck. About a lot of things.
