This episode is actually "Where's the on button?" Get ready for the betrayal you've all been waiting for! The choice has been made. Enjoy. Disclaimer: I don't own Mako Mermaids.

I was at Zac's garage. We were trying to find out how the trident worked. Or where the "on button" was.

"So what does it do?" Cam asked.

"Well most websites say the same thing." Zac replied. "It's a mythological weapon of great power and magic. Used to create earthquakes, tidal waves, and storms."

"And how did they do that?" I asked.

"Doesn't say." Cam picked up the trident and started waving it around like they did in action movies.

"Sorry Cam, but I don't think that's actually going to fire it up."

"Well this one doesn't seem to work. Great, we pull off the perfect heist and for what? A useless antique. Maybe we could sell it."

"This was used by gods who live underwater, who have power over the ocean and weather." Zac explained.

"So?"

"So maybe it has to be wet." Cam holds it while Zac opens a water bottle.
"Really, Zac? The old fashioned way?" I asked. I stuck my hand out, concentrated hard, and slowly water came into my hand out of the air. Both of the boys' jaws fell.

"B-b-blair?" Zac asked. "Did you just… pull water out of thin air?"

"Yes. In some days you've just got to open your brain to the infinite possibilities."

"Blair that's… AWESOME!" Cam exclaimed. "Did you know about this, Zac?"

"Even water has it's secrets."

I encased the water on the trident. But nothing worked. "Maybe there's… a magic word."

"You read too many fairytales."

"Oh and mermaids aren't real. Maybe you have to speak mermaid."
"Is that even a language?"

"No but the closest ones I can think of are Latin or Greek."

"Do you happen to know any of them?"Just as I was about to retort, I heard an unexpected visitor.

"Zac?" It was Lyla.

"Guess what they're after."

"If it's that important, there's no way I'm giving it back." I was afraid he would say that. I had already tried a gazillion times to convince him to not get the trident and most of those tries ended up in arguments. Zac is sometimes as stubborn as a rock. Must be a trait mermen get. I had no idea how right I was. We stepped outside to find the trio outside right in front of us.

"Well? Where is it?" Nixie asked.
"Where's what?"

"You know exactly what we mean."

"Sorry I don't know what you're talking about."

"It's dangerous. You're messing with power you can't understand, let alone control."

"Have you been eating swordfish? I think the mercury's starting to mess with your brain."

"You stay out of this land boy. We weren't hatched yesterday."

"Zac please. I know you don't believe this but we're on your side. You have to trust us."

"Yeah right. Like that's going to happen."

"I bet its inside. We'll take it if we need to." We raise our arms to use our powers but our preparation was cut short when Rob came.

"Shouldn't you be getting ready for school?" He asked.

"Don't worry. We were just leaving, weren't we boys?" I asked.

"Yeah."

"We'll be seeing you soon, illegal puer." Nixie said.

"Oh they mean it, they'll be back. You got to find a good place to stash it. Fast." After Rob left the poolside area, Zac dropped the trident there.

Later, at Suncoast High…

I was on my way to class, when I saw Evie walk toward me.

"Hey Blair. I would like to include you in the school magazine interview with Principal Santos." I raised an eyebrow.

"Why? I'm sorry I'm confused."

"Well, you share quite a resemblance to her."

"And I'm involved in the interview because?"

"Because I know that she shares some kind of special bond with you. And having you around just might make this article much more interesting. After all it's just an interview."

"Well, why not?"

"Good, come to Principal Santos' house this afternoon after school." She turned around and left. Oh no what was I thinking?! I can't let people know-let alone Evie that I'm the principal's long lost daughter who was said to be dead. Wait a second. That's when it hit me. She invited me because she's using the interview to get to me and Santos. Well I can't back out of it because once Evie insists, she insists.

Later, at Rita's home…

I biked to Santos' house. It's a really nice place if you check it out. Once I stepped in, I felt like I was home. I didn't even know the half of it.

"Blair? What are you doing here?" Zac asked.

"I was just going to ask you the same question." I replied. "Besides, your girlfriend insisted I come." We walked to what appeared to be a living room. It had a flat screen TV, a nice kitchen and a great view. Being a principal does have its perks. And one of them is: a really fancy house. Evie arrived with David. We all sat. I sat with Ms. Santos, or Mom.

"Let's start with the basics." said Evie. "Where were you born?"

"On the Barrier Reef. My parents were sailing around the world." She replied. Sailing around the world. Hmm, I thought. Not a bad cover story. After all, any cover story is a good cover story as long as it fits the subject you're covering up. Wow, that's a lot of coverage in one sentence.

"Seriously? I've never seen you swim."

"A waterlogged childhood made me keen on dry land. Most of my education was conducted overseas. The Caribbean, Fiji, Hawaii."

"That's a lot of swimming." I whispered to Zac. But suddenly, the mermaid trio came up.

"What are you doing here?" Nixie asked.

"We're interviewing your aunt for the school magazine."

"Why?"

"To clear up the mystery of her life. It was Zac's idea actually." WHAT?! If one piece of our secret gets out to any of them, he's answering to moi!

"It's perfectly ok girls." Rita said assuredly.

"The kids at school are dying to know how you came to live with Principal Santos." And by "the kids" I'm sure she meant herself.

"I think we'll leave you guys to it." said Sirena.

"Seriously, we'd love to involve you in the article. You're such a big part of your aunt's life."

"You know we'd really just get in the way."

"I'm used to that."

"I'm sure it won't take long."

"Zac." I said. "A word please?" He walks with me until I came across a hallway.

"Have you gone insane? What are you doing?"

"Since when is it illegal to interview someone?" he asked absent-minded.

"You're playing with fire. You know they don't live here, you know Rita's not their aunt, and you know she's my mom!"

"So?"

"So be careful or Evie's going to blow our secret. And when I say our secret, I'm including you." I yank him by the ear and pull it close enough to make my words crystal clear.

"Keep your girlfriend under control, or we all lose." We started to walk back.

Line break…

"… then I came back to Australia and ended up as the principal of Suncoast High.

"And then your nieces arrived. Let's talk about them. So where are your parents?" No response. Seriously? They've been here for like almost 4 months already. You think they could have made at least one cover story by now.

"Sailing." Rita said. Sailing really? You've already used that one! Rule number 3 of making a cover: Never copy someone's cover story.

"All of them?"

"It runs in the family. It's a real passion."

"Okay. Why don't they go to Suncoast High?"

"Well they're just visiting so I'm home-schooling them."

"They've been here for a long time." Wait a second, not only was she using the interview to get to me, she was using it to get to them! I was a fool.

"I thought this interview was about Principal Santos." Zac interjected.

"It is. All aspects of her life. How old are you?"
"We're 16." Sirena replied. Wow, what a coincidence. That's how old Zac is!

"All of you?" David asked. "I thought you were sisters."

"You're cousins." Zac said. "Right?"

"Right we were all just born around the same time." Lyla said. In a way they are

"You're lucky your aunt has such a big house. Do you share a bedroom?"

"No/Yes."

"Excuse me?"

"I mean yes."

"We used to share but now we don't."

"I think that we've got enough for the article, right Evie?"

"I haven't finished my questions yet."

"No one at school cares where they sleep." I said.
"I think they do."

"So David, let's go get some photos now."

"Excellent idea Blair. Shall we go up to the roof? Evie come on." We walked to the roof. The view there is awesome. I feel like I could have lots of talks here.

"Just look natural." said David. He then took some photos of Rita and the girls. Then Evie told him to take some photos of me and Rita! He took about 15. Then he took some of me. Finally we were done.

"Hey David, could you get a few photos of the house?" Evie asked. "Just to get a feel for who you are."

"I'm sure you've got more than enough to write your article." Rita said.

Later at Zac's pool…

I levitated the trident out of the pool and set it on the ground before I could get wet. Cam then dried it with a towel. When we went inside of Zac's room, he started telling us about what he discovered while I was being photographed.

"You guys should see this place under Rita's. It's like a pirate cave. Or an antique shop. I've got to get back in there and check it out more. And Blair, I saw a photo of you, when you were a baby, Rita, and your dad. I got to tell you, you look just like Rita." I smiled. A warm feeling brushed my heart.

"I have to check that photo." I said.

"Yeah, and borrow some of those gold coins?" Cam asked.

"One, she's a very powerful mermaid, two, she's our very powerful principal, and three, she happens to be my very powerful mom. In other words: bad idea."

"I said borrow, not steal."

"Actually borrow is a nice term for steal."

"I'm more interested in finding out what else she's got down there."

"Like a way to turn that on?"

"All her secrets are in there. I just need more time to look."

"And how are you going to do that? It's not like you can just barge in from the front door."

"I don't need to. There's another way from the sea. I saw it. I could smell the salt water."

"Well that's one disadvantage of being a mermaid: They have back doors they can't lock."

"Excuse me, I need to do something." I said. I rushed to my room, got my phone and dialed Rita's house.

"Hello?" I heard Lyla's voice.

"Lyla, get your friends and get to the grotto. Zac is on his way." I turned off the phone. I then went to the computer and got my friends on my line.

"Hey Blair." Rosalina said. "Guys, I believe that Zac has found a way to get to Rita's grotto undetected. I want you fill your water guns and bring them. Stephanie, I need you to get the blueprints for Rita's house. Helen, when you get to the bookcase down the passage to the right, there is a book marked, "Mermaid Myths". And Rosalina, make sure no one is seen until I say otherwise. And hurry. The choice has been made. Now go!" I turned off the computer and got one last look at my room, where I slept in for 13 years.

Later, that night…

We were in the ocean trying to find the entrance to Rita's grotto. With all the stress in my mind, I've sort of forgotten where it was. Zac then taps me and I follow him coming to this cave. We then got dry, and headed toward the grotto. It was so beautiful. I felt like anything could happen here. I stopped by a photo of my dad and mom, with my mom as a mermaid.

"Thought so." I heard Lyla. Sirena and Nixie joined her sides.

"Just give us the trident, and get out. It doesn't belong to you."

"Since I'm the one holding it, I'm kind of guessing it does."

"You don't know what it can do. You don't understand it's power."

"Blair, what do you think we should do?" It's time.

"My name is Blair Christine Blakely. But that's about to change!" I then levitated the trident out of his hands and walked on a step. "Guys, come out now!" Quickly, each of the girls came out of a curtain. Stephanie took the east point. Rosalina, west. Helen went beside me. I handed the trident to her.

"Blair, what are you doing?" Zac asked.

"Zac, my known name is Blair. My true name is Thalassa Santos. I admit I am Rita's daughter. I couldn't stop you from getting the trident but now you have it. And it doesn't have any power. Zac, what you held what a weapon of destruction and murder. In a war between mermaids and mermen, this trident was used to destroy villages and take lives. Families were torn apart as well. Using the trident won't just affect the people you attack. It'll hurt everyone. You have no idea what chaos will be unleashed."

"In other words Zac, the girl you knew was merely a fantasy in reality." Helen said. "She's been conspiring behind your back."

"That's a lie!" Zac shouted.

"It's the truth. When she found out who she was, she set out to destroy your little team." Stephanie said. "From the inside out."

"No! Blair would never!"
"Tonight her plan was to strike." Rosalina said. "But she took pity. Even if she betrayed you, she still loves you. Despite this she was kind enough to warn even the 3 girls behind you in time to stop you."

"Liar!"

"Zac. It's the truth." Zac's face turned from angry to horror-stricken.

"Sister? Why?"

"Because you could never give her what she needs." Sirena said.

"I trusted you! I practically raised you!" He raised his hand. We all do so except for my friends who fire up their water guns. Suddenly, the trident's stone starts to glow bright blue. Moonlight is then being drawn in a silvery-blue line of energy from my ring into the trident.

"Thalassa?"

"I'm not doing anything! I can't turn it off!" After what seemed like forever the charging was complete. This was bad. Really, really bad.

"What the heck happened?" Rosalina exclaimed.

"I think it just got charged."

"And we'll be its practice dummies unless someone thinks of something!" Helen shouted. But we're too late as Zac leaves. I fall on to my knees.

"What have I done?!" I cry.

"There's a powering mechanism?!" Helen exclaimed. "Stephanie why didn't you tell us?"

"Well, because I wanted us to fail. OBVIOUSLY I DIDN'T KNOW!"

"Now Zac's got the trident." I said. "Because I gave it to him. I destroyed Mako Island. Just like the prophecy said."

"Forget the prophecy." I heard Nixie. "You're worried about your destiny? Write a new one. You're angry at Zac for using the trident, then show him why he shouldn't. You're upset about your dad, make sure he didn't die for nothing."

"Thanks guys."

"So you're finally joining us." Lyla said. "Took you long enough."

"Can you guys get Rita down here? I wanna say hi to her, but first tell her what happened." Then out of nowhere, Nixie gave me a hug.

"I'm so sorry I called you illegal puer. I was scared of the choice you would make. Now that you've made it, I'm so proud of you. We'll get Rita down. And then you'll be reunited with her."

They did so. They explained everything to Rita and what happened. They then stepped out of my way and then I saw the face of my mother. She looked shocked. I ran up to her and hugged her, tightly.

"Mother." The world stopped as she hugged back. We were finally reunited after 14 long years.

"Blair, I.." I put up my hand to silence her.

"Blair is gone mother. Thalassa has now returned in your arms." We hugged once more. "I need to try one last time. Oh and call me Thalie." I ran to the pool, dived and sped to Zac's house. I got dry and ran to Zac's house. I opened the door. Zac looks at me with hatred.

"What do you want?" He asked.

"Zac please. I'm sorry. I'm so sorry! I never meant for any of this to happen."

"So why did you let it?"

"I don't know ok? I don't know! I was just under a lot of stress. I had to chose but…"

"So it was all a trick? You were just pretending?"

"Zac, you said you'd be my big brother no matter what remember?"

"Cam was right. You were never my sister from the start. Now get out of my room." Holding in tears I ran to the jetty, jumped in and swam to the grotto. I entered it, crying.

"Thalie?" I hear Lyla. "What happened." I ran into her arms still crying.

"I betrayed my brother. He hates me. I'm scared. What have I done?"

"It's ok, you did what you had to do. I hope this means you'll stay. After all, you are family."

"With Zac kicking me out of his house, what choice do I have? It's actually not bad. Where's my mom?"

"I'll show you to her, and your new friends went home. Rita thought it was best that way." She leads me out of the grotto, through some passageways upstairs to this blue room with a large bed in it. It looked like it was newly refurbished. Waiting for me was my mother.

"I'll leave you guys alone." With that Lyla left.

"I already called your parents. I plan to take you back under my care, but tonight you'll sleep in your room. When I found out you were alive, I took the liberty of making a room for you. I hope you like it."

"I love it!" I hug her. I noticed my pj's on my bed. They were my size though.

"Do you mind if I change?" I asked.

"There's a bathroom over there." I had a bathroom next to my room? Awesome! After I changed into my blue pjs, which were a blue tank top and blue pj shorts.

"Thalassa, I understand this must have been hard for you. I hate that you had to go through that."

"At least we're now reunited." She put her hand to my face and I feel warmness. So this is what a mother's touch felt like.

"I can teach you all that I've learned. There's room for another in my mermaid schooling class. Remember, even water has its secrets. And I'll show them all to you. We'll unlock every mystery in our path and forge a family together, as mother and daughter." I then lie in my bed, with my mom folding the covers over me.

"These gifts and the past that we share Thalassa, it bonds us. This is who you are, my daughter. Who we are. Now get some rest. It looks like you will need it." She kisses me on the check and sings me to sleep

That's it for now folks! Be sure to review! So Blair, I mean, Thalie has made her choice! The wait is over. But what happens next when Thalie has her first confrontation with Zac, armed with the all powerful trident? Stay tuned to find out.
