Cleo POV

As I walked through the thick forest, I vaguely recognised the frenzied calls from my friends. I ignored them though and hurried into a thicket. There, it would be almost impossible for them to find me. I sat down and breathed in and out heavily. I closed my eyes and relaxed; I needed to think. When Emma has questioned me about my aggressiveness, I honestly had no answer for her. Lately, I noticed that little things set me off. When my dad came in while I was screaming at Kim for stealing my top, He grounded me. The thing that scared me the most though, was that I merely locked my door, climbed out my window, and snuck out to Rikki's café. I knew my friends were were worried about me, but really, was my attitude that surprising? I, mean Hello, Teenager.

Suddenly, a nearby bush rustled: I was immediately on guard.

"Hello?" I raised my hand, and a water snake formed; it looked at me as if asking directions.

"Stay close," I whispered. It nodded and both of us inched forward.

"Rikki? Emma? Bella?" I called out cautiously.

Suddenly-" You're not a demigod, are you." It wasn't a question.

"Um, excuse me? And who are you?" A small, auburn-haired girl stepped out.

" I'm Brianna. Brianna Collins. Daughter of Hecate."

" I'm Cleo Sentori. And you're right. I'm not a demigod."

"Then what are you? I know you aren't a mortal. You can get through the borders, you control water, and obviously you can see through the Mist."

" I'll tell you, if you can keep a secret. Welcome into my humble abode." I mock-bowed and pointed to a spot on the dry earth. "Sit on the couch if you please." Brianna laughed quietly before her expression changed to that of a businesswoman. She sat down on the tough earth and while she got comfortable, I studied her delicate features. In a way, she reminded me of some sort of earth-princess. Brianna's reddish brown hair reached her waist, and was braided loosely. Several flowers and twigs were stuck in her hair, and her tan face was smudged with dirt. Her eyes were hazel, and a sprinkle of freckles were dotted across her face. Brianna was wearing a almost comically orange large shirt that reached her knees, along with sage leggings and black converse.

"Well?" I blinked rapidly before registering what she said.

"Um, what do you want to know?"

" What are you!" She threw up her arms in frustration before covering her mouth. " Sorry. When I say it that way, it sounds offensive."

I tried not to grin and replied, " It's fine. But, it's easier to show you what I am."

"Okay," she agreed. My friends were getting closer and it would be bad if they saw me in all my fishy glory, in front of a complete stranger. I really didn't know why I was showing Brianna, ny something about her told me she wouldn't tell a soul.

I tugged on Brianna's arm. " Can we go somewhere else? Like that lake?"

" Yeah, yeah lets go." Brianna looked vaguely dazed. Evidently, she hadn't expected me to give in so easily

" Well? Are you going to move?"

" Sorry," Brianna shook herself out of her daze and both of us ran pell-mell towards the lake.

Annabeth and Percy were on the pier, so we decided to find a more secluded place. Before we backed off, Percy saw us. Both of them waved, although Annabeth did so rather half-heartedly. When we found a spot, I turned around and faced her.

" Can you swim?"

Brianna looked affronted. " Of course I can swim!"

" Okay! I was just asking. Alright, go in the water" She took of her shoes and jumped, while I avoided her splash.

"Good! Now watch out1" I dived into the water and swam towards Brianna. At first, she looked bored, then surprised, as my legs were covered in bubbles, then totally and \utterly shocked as my tail was revealed.

" I- you-," She sputtered.

" Yes, I'm a mermaid," I inwardly sighed. This was like the fifth time I had explained this, and it was getting old.

"But- you-how-,"

" Okay listen closely, because I don't feel like repeating myself. I go to a magic moon pool, fall in at full moon time, next thing I know, I pop a tail when I touch water, and I can control water, yada yada yada." Brianna stared at me.

"Sorry, I'm in a bad mood." I apologised. " Any ways, want a ride?"

She stared at me. " Are you crazy?"

"Pretty much." I agreed. I brushed my fingers through my tangled hair. "so now that we have that straightened out, you want a ride?"

"Couldn't someone see you?"

I smiled devilishly. "All they'll see is a blur."

"What are yo-" She was cut of as I grabbed her hands, pulled them over my neck, and swam in circle, moving so fast nothing more than a column of bubble could be discerned. Brianna's mouth was open in a silent scream, and she was gripping my neck so tightly I could barely breath. When we resurfaced, Brianna staggered over to the bank and glared at me. "Don't ever do that again." I grinned back.

"So, can you keep my secret?" Brianna stopped glaring, and stared at me thoughtfully for a few seconds. Then, she nodded.

"Yes, I think so. I may be even able to help you, and keep suspicious people like Annabeth off your tail,-no pun intended."

I laughed, then put out my hand. " Friends?" "Friends." We shook hands.
