This is my 1st time writing a fan fiction and I've been think up this one for a long time know, so, I hope you enjoy J

Chapter 1:

It was a calm day in Ninjago and the ninjas were training when Sensei Wu came out.

"Cole, you've got a letter!" Sensei Wu called out

Cole went over a got the letter off Wu and read it, his face morphed into a face of shock, fear and anger.

"What is it Cole?" Lloyd asked

Cole didn't respond, he just threw down the letter, went over to a punching bag a punched it right off its chain.

Lloyd picked up the letter and read it for himself.

"What is it?" Kai asked

"A girl called Crystal has gone missing." Lloyd explained

"Who's Crystal and why did they send the letter to Cole." Jay asked

"We'll ask questions later, right now there's a serpentine attack in Ninjago!" Nya called out

"Let's go!" Zane called as they ran off.

The ninjas reached Ninjago and Nya was right. Serpentine were attacking and the ninja were fighting them off left, right and centre with Cole being more aggressive than normal. Suddenly they heard a loud scream as they were fighting off the last of the serpentine. The ninjas looked up, some off the serpentine were holding a young girl, around the age of 19, off the edge of a building when all of a sudden they knocked her out.

"CRYSTAL!" Cole called out as he ran over to the building as fast as he could.

After Cole started running, the serpentine that were holding Crystal, threw her of the building and she was falling fast but Cole was able to catch her just as she was about to hit the ground.

Cole held Crystal with a scared and worried look on his face. She had long blond hair that had curls and she was wearing a pink top with dark blue jeans and pink and white sneakers.

Cole turned to the other ninjas.

"We need to get her somewhere safe" Cole told them and they took off to the Destiny Bounty.

Cole sat in a room with Crystal lying on a bed, still knocked out.

"Hey Cole." Lloyd said has he entered the room where Cole and Crystal were.

"Hey." Cole answered not looking up from Crystal

"So how do you know this girl?" Lloyd asked as the other ninjas, Nya and Sensei Wu entered the room as well, they wanted to know as well.

Cole stood up, looked at Crystal then looked at the others.

"Crystal is…*sigh* she means a lot to me. She means the world and more to me. If anything was to happen to her, I would never forgive myself." Cole explained, occasionally looking over at her

"But how do you know her?" Kai asked

"She's my…" Cole started, then they heard Crystal groan

"What the…where am I?" Crystal started, worried and confused as she opened her bright blue eyes.

Cole whipped right around and went over to the confused girl

"Crystal, it's ok. I'm here." Cole calmly stated to Crystal

"Cole? Cole!" Crystal exclaimed, lunging into Cole's arms

They spun around from the force and Cole put her on the ground, making sure she was standing up before letting go.

"Is she your girlfriend or something?" Jay asked

"Why does everyone think that about us?" Crystal asked Cole

"I have no idea." Cole answered Crystal

"Who are these people?" Crystal asked as she looked at the others.

"And you still haven't told us who this young lady is." Zane pointed out.

"Crystal, this is Kai, Nya, Jay, Zane, Lloyd and Sensei Wu. Guys this is Crystal, my little sister." Cole introduced every one in a calm tone

"Sister! You never told us you had a sister!" Jay spoke up.

"Yeah. Why didn't you tell us?" Kai questioned

"She doesn't like being talked about." Cole explained looking at his sister, lifting an eyebrow.

"What? It's embarrassing and un-comfortable." Crystal told her brother who, of course, knew this.

Cole, Nya and Sensei Wu made sure Crystal was ok as the others went out to train some more.

"So what did those serpentine want with you?" Cole asked his sister, cracking his knuckles.

"Um, Cole. Didn't mum always tell you not to crack your knuckles?" Crystal told her brother, lifting her eyebrow.

Cole just rolled his eyes and asked again

"What did those serpentine want with you?"

"I don't know. I was just walking out from my dance class when those…snake thingies"

"Serpentine." Cole interrupted his sister, correcting her.

"Yeah, yeah, if that what's they're called. They just attacked randomly and grabbed me, took me to the top of that building and I tried to get away but then they knocked me out. Next thing I woke up here…where ever here is." Crystal explained.

Sensei Wu just nodded.

"Cole, why don't you show your sister around?" Sensei Wu suggested

"Yes Sensei. Crystal come on."

Cole showed Crystal around, then they went on to the deck. Then all of a sudden Crystal had a panic attack, she felt her chest tighten, her heart rate speed up and she found it hard to breathe.

The other ninja turned around in shock as Cole lead Crystal over to the side.

"Crystal, look it's ok. We're not on water, look" Cole spoke, trying to calm down his sister.

Crystal looked over the edge and saw land that was miles down below instead of water as she started to calm down.

"Sis. It's ok. Would I let you on a boat if it was on water?" Cole continued as his sister started to calm down from her panic attack.

"What happened? What was that?" Lloyd asked

"Am I aloud to tell them?" Cole asked his calming sister and she just nodded as she took deep breaths.

"Why do you have to ask her?" Nya asked as she and Wu came out to see what all the commotion was about.

"Because she is very conscious about it." Cole answered Nya's question and then went on to tell them what just happened, "Crystal is very hydrophobic."

"Hydrophobic? What's that?" Lloyd asked

"Hydrophobic is a person with hydrophobia and hydrophobia is the fear of water." Zane explained.

"Why would anyone be afraid of water?" Jay asked

"I wasn't always hydrophobic," Crystal stated after calming down "I used to love being in the water."

"Yeah we used to call her 'mermaid' cos we could never get her out." Cole added, with a bit of a chuckle

"Why did you get hydrophobia?" Zane asked

Cole and Crystal looked at each other with Crystal having sadness in her eyes and then she looked down and continued.

"One day we were out on a boat trip when I was about 6 or 7 and the captain didn't notice a rock sticking out of the water and we crashed. I would've been able to swim up easily but something or some one, I couldn't see what, grabbed my leg and I couldn't swim up. I couldn't hold my breath for that long and so I passed out, and next thing I knew, I woke up on the beach with crowds of people surrounding me and mum, dad and Cold looking relived and I heard someone say that if I stayed under for and minute longer or if I didn't wake up when I did, I would've…would've…died." Crystal stammered, crying and Cole supporting her and with a few tears in his eye with the memories of almost losing is little sister from the terrible event.

"Wow." Nya stated, breaking the silence "do know how you got out of the water?"

"No one knew, no one saw this is all we know about my potential killer." Crystal said as she lifted up her right pant leg. There they saw a scar from thick to thin, wrapping around the top of her ankle.

"Whoa!" the others stated with shocked looks on their faces, even Wu was shocked.

"Zane, do you know what would've done this?" Kai asked

"Nothing in my data base has the capability of doing this." Zane told Kai, earning a confused look from Crystal.

"Did he say 'data base'?" Crystal asked as she put her pant leg back down.

"Yeah, he's a ninjadroid." Jay explained

"Ninjadroid?" Crystal asked

"A ninja robot. Zane's a robot." Cole clarified

"Oh. I thought he sounded a bit robotic. No offence." Crystal stated

"None taken and I sounded robotic, why didn't say any thing?" Zane asked

"I didn't want to be rude." Crystal answered.

Later that night they were having dinner and Crystal cooked tonight as a thank you for letting her stay with them, they agreed for her share a room with Nya.

"Hey Sensei, why did you let sis stay with us?" Cole asked

"Why do you ask?" Wu asked back

"Just wondering, not that there's anything wrong with it though." Cole answered

"I have a bit of a feeling about her." Wu answered the original question

"Grub's up!" Crystal brought in a big roast pork then she ducked back in the kitchen and pulled out 2 smaller platers of roast veggies and a small pot of mashed potatoes.

"Yeah boy!" Cole called out as his sister brought in the delicious dinner.

"Dig in." Crystal said as she sat down then popped back up "Oops! I almost forgot about the gravy!" as she ran into the kitchen and brought out a small pot of gravy and set it on the table and took her seat.

"Sis, you out did yourself again." Cole told his sister

"I have? But I just did a small meal." Crystal said and as she did the others' eyes nearly popped out of their heads.

"If this is a small meal I'd want to see what you'd call a big meal." Kai said as he put some pork on his plate.

"Her idea of a big meal is a banquet." Cole explained as he ate a piece of roasted carrot.

The others looked at Crystal

"What? I like to cook." Crystal shrugged

"Yeah, it's her 2nd talent" Cole added

"2nd? What's the 1st?" Lloyd asked

"Dancing." Cole answered

"Would you be able to demonstrate?" Zane asked

Crystal's face went bright red

"Yes she would." Cole answered for her

"COLE!" Crystal yelled at her brother who just looked at with a smug look

"You need to get rid of this shame of yours plus we both know you a great dancer." Cole told his making sure that she knew that she wasn't getting out of this.

Crystal sighed and said

"Fine but can we do it tomorrow?" Crystal asked

"That would be wise for she's had a long day." Wu piped up

"Oh! On the topic of dancing, Cole, I finally learnt how to do the triple tiger sashay." Crystal informed her brother.

"Awesome! You're showing me tomorrow." Cole said as he went in for seconds

"Fine." Crystal sighed, finishing off her plate.

The next morning, the ninjas and Wu were preparing breakfast.

"Hey, where are the girls?" Kai asked

"I know where sis is, not Nya" Cole answered

"Where's your sister then?" Zane asked just as Nya walked in looking a bit annoyed

"There's Nya but where's Crystal?" Jay asked

"Cole! Something's wrong with your sister!" Nya exclaimed

"Why?" Cole asked with a smug look on his face

"She won't wake up!" Nya said annoyed

"Nothing's wrong with her, in fact I would be worried if she wasn't." Cole explained "Don't worry I got this." He said has he went to grab his sister.

A second later Cole walked out with Crystal slung over his shoulder, fast asleep

"I thought you were going to wake her up?" Kai questioned

"I am." Cole explained as he got a tray of ice out of the freezer and was just as he was going to tip the whole tray down her back, Kai asked

"Isn't that a lot to trip down her back?"

"It takes a lot to wake her up." Cole as he tipped the whole tray down her back.
