A/N - So I'm still working to get the hang of this story, you know, to see where the plot will go. I build the story as it goes, I don't really plan it out before I start writing it, or at least, not in a detailed manner.

Hope you like this chapter! I welcome criticism and opinions with open arms! It'll help me a hell if you guys review, and I'll love you endlessly people!

Cold, dark and empty caves that irradiate loneliness and sorrow never bothered Pitch, in fact, he loved those places. So the most reasonable thing to do for him was to make a hideout inside one of those cold, dark and empty caves. But don't let that fool you, inside this fortress of stone, you will find a castle crafted by the very same hard material.

The Boogeyman sat on his stone made throne, it was elegantly simple.

"So Faith has finally made an appearance hasn't she? Although she goes by the name of Serenity" Pitch ran his hand along the back of his Nightmare "One of the most beautiful, yet mundane creations you have made, dear Man in the Moon…"

A sneer graced his face as he realized the threat she would be "Even though she doesn't seem powerful at all…" the image of the arrow and the birds clearly being the proof. He even wanted to chuckle at how inoffensive she seemed, "… but her mere presence will inspire hope and determination inside the guardians, and we don't want that do we?"

His Nightmare huffed and clicked his hoofs in agreement.

Pitch suddenly came with an idea that had him smirking "I think it will be fun to have my own little pink angel in here with me don't you think? She can keep me from being all alone and sad in this big lonely castle" fake excitement dripped from his voice followed by his deep maniac laugh.

"We shall have so much fun together my dear little Serenity"

"So every tooth contains the most important memories of childhood?" Serenity asked one last time.

Tooth nodded "We had every child's teeth here, even yours" she said looking at Serenity and Jack.

"Mine?" the pair asked in unison.

"From when you were human, before you were turned to spirits" Serenity had to stop herself from giggling at Santa's unique accent, it had been so long since she interacted with someone, so his way of speaking brought her wonders.

That's when she felt an imaginary slap on her cheek, "Did you just say that we had a life before this?" she whispered.

"I was someone before being Jack Frost?" Jack was shocked, he couldn't understand, how he could not remember a single thing before he woke up as a spirit.

"We were all someone before this" Bunny said. Serenity got distracted when she started imagining Mr. Bunnymund as a human kid, but her mind was cut short
when she heard Santa laughing loudly as he said "You should have seen Bunny!"

"When I woke up in the pond, I just assumed that…" Jack looked absolutely lost. He jumped slight when he felt someone placing a hand on his shoulder. Serenity's small smile showed him only support for she knew what he was going through. A tiny blush came upon both their cheeks when they stared at each other's eyes without either of them blinking.

Don't squeal Tooth, don't squeal, the fairy chanted in her mind while looking at the two spirits blushing.

Bunny groaned in horror "Oh God no, just what we needed!" Jack and Serenity snapped their gaze when they heard the Easter lord making their blush worsen.

Sandman could only do was show his question mark sand figure to express his confusion about what had just happened between Frost and Faith, from which Santa just laughed "You are the oldest in here, yet you don't know what happened?!" he cracked up even more.

Their teasing ended when Tooth panicked as she saw feathers falling from her tail "Oh no!" this meant it had already started "The children! Were too late! They're starting to stop believing in me".

Santa Claus would never let this happen "No! No! No such thing as too late!" Serenity could almost see the intense fire in his eyes. He started thinking hard for anything they could do to help Tooth, he mumbled any ideas he came up with, you could almost see the smoke coming out of his ears.

That's it! Santa thought, he pointed at everyone "We will collect the teeth" that certainly threw them off.

"What?!" Tooth exclaimed "We collect teeth, children keep believing in you" Santa stated making it seem as simple as possible.

Serenity started calculating in her mind "If we all work fast, we might be able to do it!" but Tooth didn't buy it "You guys are crazy! Its 7 continents! Infinite kids! Absolutely impossible with only six of us!"

Santa and Bunny narrowed their eyes "Ohh don't tell me crap! I deliver presents to millions of houses in one night!"

"And do you know how many eggs I hide?" Bunny huffed.

"Jack stood there, thinking deeply "We will help you Tooth, no doubt in that… But still, we will have to face Pitch eventually right?"

Bunnymund stuck out his chest and closed his fists in anger "Of course! We will not let that git keep sabotaging us!"

"Then, we will get out memories back" Serenity smiled encouragingly at Jack who returned her smile gratefully.

Sandy could only nod in agreement, it's not like he could contribute something that they could understand… They never could comprehend his drawn messages.

Serenity smiled at the fairy "So I think we will be helping you Tooth, no need to worry, it will only stress he rest of them agreed with fierce determination.

"T-Than you so much guys! Thank you! Thank you!" Tears of hope spilled from the corners of her eyes.

"So let's get going!" Jack smiled brightly.

"Ha haha Bunny! I'm so a head of you!" Jack laughed, wind surrounded him as he flew around the houses. Next to him hopping from roof to roof was Mr. Bunny, meanwhile, Santa opted for chimneys as it worked for him perfectly.

Serenity laughed "I bet they'll start a competition" Sandy smiled thinking the same, bet he didn't think he would end up being part of it.

"A race? Is it a race! Are we playing?!" Santa's eyes shined, his inner child cheering loudly.

"OH! Two incisors down there! One front tooth down the street! Oh God! A molar!" Boom! Tooth collides with a huge toothpaste sign.

"Are you ok?" Jack asked her "Perfectly fine! It's just, it's been so long since I've been out in the field" Tooth was moving frenetically turning her head every second from house to house.

"How long exactly?" Serenity asked flying up to them.

"440 years give or take"

How peaceful and serene, Serenity thought. She and her faith birds had gone to collect their first tooth, but as soon as she saw the little girl, she had to stop and admire the happy sleep she was having. "I'm so happy to witness this… now, the tooth" when Serenity placed it inside a bag, one of her birds went to the bed and stood next to the pillow.

"What are you doing sweetie?" She whispered to her bird, but the little creature ignored her by sitting there making itself cozy "Hey! It's not time to sleep!" What was her bird doing?!

Pop!

Egg! And egg appeared beneath the pink bird "Wha- Wha-! What?!"

"How in the world did you have an egg the same size of your little body inside of you!?"
