Natsu and Lucy were both fast asleep in there bedroom expecting a nice quiet night until they heard the front door burst open.

"Natsu!"

"What the… Gray is that you." Natsu grumbled sleepily and angrily.

Nashi started to cry from the sudden awakening.

"You go downstairs I'll get Nashi." Lucy said able to tell something wasn't right.

Natsu stomped downstairs.

"Gray what are you doing in my-!"

Natsu froze when he saw Juvia blue as her hair and covered in frost.

"Help me!" Gray cried out.

Lucy then came downstairs luckily able to calm Nashi down quickly.

"Juvia!" Lucy cried out as she put her hands over her mouth out of shock.

"Gray what happened?" Natsu asked very worried.

"This woman..she came and took Silver and Ame…then when Juvia tried to stop her...she froze her." Gray said as tears ran down his face.

"Give her over I'll see what I can do!"

Gray quickly gave Juvia over to Natsu praying his fire dragon slayer friend could save her.

Natsu took her over to the coffee table and laid her on it. He began to think over how to do this for is seemed this could be very risky.

"Happy!" Natsu called out.

A few seconds later came flying in was the blue feline.

"Natsu me and Carla are trying to sleep what are you...Juvia! Natsu what's going on?"

"Happy I need you to go and get me that book we got after Nashi was born, you know the one on first aid."

"Aye sir!"

After a few minutes Happy came back with the requested book.

"Look at the section on hypothermia." Lucy told the exceed.

Happy looked over the book and found the section proceeding to quickly read over it. H

"There's nothing here except to her warm but that doesn't do anything!"

"Natsu please there has to be something you can do!" Lucy pleaded.

"I don't know I've never done something like this before."

"Come on flame brain there's got to be one idea in that head of yours!" Gray yelled.

"I'm doing my best Gray!"

"Well clearly not good enough!"

Gray and Natsu started to argue and fight, Lucy was trying to break them up, happy stressed out, it was all chaos.

"Quiet!" Carla yelled out.

Everyone froze and turned towards the white exceed.

"Everyone please calm down and do exactly what I say."

Natsu nodded and went over to Juvia.

"Because she is made of water this will be a lot easier since we don't need another water mage to move her blood. Lucy go grab a blanket to put over her and a thermometer to keep track of her temporary, Natsu put you hands on her neck and back, and Gray you put you hands on her head to keep her brain cool."

Everyone proceeded to do what they were told all hoping to save Juvia.

"Is there anything you need me to do Carla?" Happy asked his wife.

"I need you to grab towels lots of them."

"Aye sir!"

After they set up all the things Carla asked for Natsu proceeded to heat Juvia up. Gray sweated nervously as he used his magic to keep Juvia's head cool.

After a few minutes Juvia's skin was back to a normal color and all the frost was gone. Her breathing was also back to normal and she at last started to move a bit.

Meanwhile Gray sat in thought feeling everything that had just happened was his fault. Natsu noticed this and came up next to Gray.

"Gray what exactly happened and where are the twins?"

"Gone." Gray responded quietly.

"Gone? But where and who, Gray you've got to tell me the whole story or I can't help you."

Gray took a deep breath.

"A few days ago a woman by the name of Delilah broke into our house. She said that she was from Avatar and there to complete Zeref's work."

"Wait what! Zeref but he's gone so why are those Zeref worshippers still around?" Natsu said as he started to get angry.

"That's what I said but she said they still had to finish his work and end humanity."

"What, well what does that have to do with the twins?"

"She said that Zeref invented a doomsday device that required the power of those with the greatest water and ice magic potential."

"And they think your two babies who can't even walk let alone do magic are the ones?"

"You know how powerful they'll get we've seen it for ourselves. It took both me and Juvia just to defeat both of them and they were as old as Lucy when she first join the guild."

"Yeah you're right, but how did she take them if you knew about this?"

"I've been tireless watching them for past few days and tonight Juvia knew I was unbelievably tired and said I needed to take break and sleep. My guess is she was waiting for that moment and that's when she made her move. I heard Ame crying so I rushed up their with Juvia when we also heard the scuffling. We both went to attack her but she practically froze Juvia and put an ice wall in front of us to keep me stalled. I can't believe I let her do that I'm their father I'm supposed to protect and keep them safe and I'm failing them unbelievably!"

Gray started to get angry and frustrated at himself.

"I know it's hard believe me when Nashi was taken I felt the same way, but there's not much we can do right now especially with how sleep deprived you are right now. Get some rest and we'll both go after them and not come back until both of them are home no matter how long it takes."

Gray nodded blankly not really wanting to be around anyone at the moment.

"Alright I'll see you in the morning." Natsu said gently.

Natsu turned off the lights and went back upstairs. Gray just closed his eyes and went to sleep trying not to worry about his children but failing miserably.

One hour later there was a sound of rummaging throughout the Filibuster house. Food was taken, maps supplied, baby items stored, and anything else that was felt as necessary.

After a few minutes it stopped and the rummaged went and opened the door to a rather angry Juvia.

"Gray what are you doing?" Juvia asked sternly as she crossed her arms.

"Juvia you're alright!" Gray said happy as he hugged her.

"Don't you Juvia me when you're about to leave without even saying goodbye!" Juvia said angrily as she pushed Gray off her.

"I have to get them back I can't let them be subjected to what Nashi was when she was taken."

"And that's going to happen because I'm coming with you."

Juvia went past Gray and went into the house to pack.

"What! But you need more time to recover you can't just-!"

"Gray I'm a very angry mother right now and I did not spend eighteen hours bringing our children into the world just so they could be taken in a few minutes by some some Zeref worshipping witch."

"But Juvia-!"

"Gray we are married and a team if both our children were taken it's going to take both of us to get them back. Now are you going to help me pack or not?"

Gray took a moment but knew what he needed to do. He started to help pack a second bag causing Juvia to smile.

Gray honestly didn't know what he was thinking, he knew that without Juvia he wouldn't succeed, without Juvia Gray would not be complete.
