Cleo, Bella, and Rikki were wading in the moon pool at Mako Island. The three just needed to be alone for a while. Suddenly, another figure entered the pool from the underwater entrance. The three girls turned wondering who the fourth person could be.

Each girl had their suspicions. Cleo wanted her boy friend, Lewis, to be there, but she knew that would be impossible considering he was overseas. Bella also wanted her boyfriend, Will, to be there. Unlike Lewis; however, Will was just a few miles away. Rikki didn't have a boyfriend but deep down she knew that she wanted Zane to be there supporting her.

After the girls turned two of them realized who it was and were shocked. The mysterious girl was really happy to see Rikki and Cleo. Bella, on the other hand was really confused.

The four girls swam back to the shore and Rikki steam dried each of the girls until their mermaid tales disappeared, then the explanation began.

"What are you doing here? You're supposed to be in Paris or somewhere exotic." Cleo questioned the girl.

"Don't I at least get a hug before being questioned?" she fired back. Cleo and Rikki hugged the girl while Bella stood again behind them confused. After the hug Rikki gave the girl the tell me everything look.

"I'm back for two weeks or so. More importantly, what's new? I see that you've made a new friend." The girl said smiling at Bella.

"Hi, I'm Bella. And you are?" Bella asked the girl

"Nice to meet you Bella. I'm Emma." Emma smiled.

"Not to be like rude but I suggest we go somewhere more private to continue our introductions." Rikki said a bit more firmly than she needed to.

"Okay lets go to my house then," Cle suggested in order to keep everyone from arguing.

"What about Kim? You know what happened last time." Bella's words forced Cleo to remember that Kim nearly found out their secret.

"She's not home she's at her friends. Now lets go. It looks like it's going to rain and you know what'll happen if we aren't indoors by then." Cleo urged all of them to get going fearing that they'd all get wet and turn into mermaids.

When the girls got into Cleo's room the real introductions began.

"SO what's new? I see you replaced me." Emma hinted at Bella knowing that she would provoke someone to tell her the truth.

"Well Lewis is gone for now. More importantly we didn't replace you. We met Bella like a week after you left. She's one of us now and she knows the truth." Emma stared at Cleo as if she were crazy.

"You told her? Why? How long was I really gone for? It seems to me like it's been longer than a year." Emma said really annoyed at Rikki and Cleo for telling anon mermaid the secret.

A vibrating sound caught all the girls attention. Bella after a few seconds of determining it was her cell going off and not any of the others grabbed her bag from Cleo's bed and flipped it open.

"It's Will. I have to go he wants me to meet him somewhere. See you later. Lets meet at Mako later. See ya." Bella said as she left the room. Sort of happy because she knew that her being in the room made things a bit awkward.

"So how was your trip? Rikki asked a bit jealous that Emma had such a perfect family compared together family that consisted of just her and her dad. Rikki would have loved to travel the world with her family.

"Amazing. So, Bella seems nice." Emma began. After a few seconds of more awkward silence Cleo and Rikki described everything that happened within the last year such as Charlotte and Lewis leaving. The main thing that Emma was really interested in was Bella. Emma really didn't have a good feeling about her and hoped that Cleo and Rikki could convince her otherwise. Emma was shocked at how Cleo and Rikki could find another mermaid yet alone with her help stop a meteorite from colliding with Earth. After half an hour of talking about Emma's trip and everything that happened in Gold Coast the girls decided that they should do something other than sit in a room all day. Cleo perked up at the idea of getting out of her room and doing something other than explain to Emma everything that she missed.

"Rikki lets show her where we usually hang out." Rikki knew exactly where Cleo wanted to go and was really excited to see the look on Emma's face when she saw where they were going.

When the girls got to the café Emma's face was shocked. She was so surprised and happy for Rikki. Rikki, almost reading Emma's reaction smiled and nodded at Emma who was thinking about the café. As the girls entered the café a smile appeared across Cleo's face. Lewis was sitting at one of the tables. Cleo quickly walked up to where he was and was tempted to kiss him right then and there; however, fear crossed her face because if it wasn't Lewis then she'd feel horrible and embarrassed and she really didn't want that.

"Lewis?" Cleo asked as the boy turned around. "Lewis, what are you doing here? I'm so happy to see you." Lewis smiled and kissed her.

"That's enough Romeo now spill, why are you here?" Rikki broke up the romance. Deep down Rikki knew she was a bit jealous of Cleo because of Zane and how much he was a jerk and so not worth her time.

"My professor and mentor wants me to meet one of his colleagues and learn from them for a while." He gestured toward Emma confused as ever.

I'm here for a while as well. My dad has some business to take care of here." Emma explained. She knew she had to keep one thing secret though for the good of the others she had to.

"Well the three of us have to go now. We're meeting Bella. See you later Lewis. I'm so happy you're back." Cleo gave Lewis a quick kiss and then the three of them were off to Mako like they used to.

Emma swam through the underwater entrance to the moon pool where the others were waiting for her. It was half an hour before the sun set and all four girls wanted to be home by dark because they knew if they weren't that their parents would get mad and potentially ground them.

"It'll be dark soon so we might want to go home first and maybe meet somewhere later." Emma suggested knowing that if she weren't home by dark her parents would freak.

"We're going to have a party tonight. In celebration of Emma and Lewis returning." Cleo said nudging Emma.

"Let's get out of here and meet back at Cleo's in like two hours." No one disagreed with what Rikki said so the four of them raced back to their hiding spot where no one really went. There Rikki steam dried everyone and they took their separate paths to go back to their houses.
