I stumbled through the woods, lost, after having just watched my beloved older brother fall under the ice of our family's pond. Tear tracks trailed down my now pale cheeks as my teeth chattered behind lips that were slowly turning blue from the cold.

I stumbled and fell to my knees but didn't get back up. "Why did you have to leave me Jack?" I whimpered as I lay down in the snow, fresh tears coming to my eyes. Above me, the moon shone brightly and a single moonbeam fell on me as I slowly died from the cold that surrounded me.

The Man in the Moon or MiM felt bad for her, as she had just lost her brother, the one who was her whole world. As the moonbeam shone on her MiM began to change her form at the same time, he raised her brother from under the ice, giving them a second chance at life.

After her transformation was, complete MiM sent down Nightlight to take her to Tooth so she could care for the child. While Nightlight was making his way to the Tooth Palace, MiM informed Tooth that Nightlight will be arriving soon with a new helper for her but she will be different then the mini versions of Tooth as MiM gave her a second chance.

"I understand. What is her name?" Tooth replied as she gazed up at the moon.

"Her name shall be Baby Tooth and she shall look like you in every way except for her eyes. One shall be purple like yours, and the other shall be blue like her brother's, Jack Frost. She shall also have a little mole under the purple eye." MiM told her.

Tooth was curious who Jack Frost was but before she could ask Nightlight showed up with Baby Tooth. "Thank you Nightlight." Tooth told him as she took Baby Tooth from him so he could get back to the moon. Nightlight nodded at her as he flew away.

I blinked open my eyes to find I was looking into big purple eyes and let out a squeak of surprise. "It's okay little one MiM has given you another chance at life as your mortal body was dying. MY name is Tooth and yours is Baby Tooth.

MiM has left you in my care so that makes you my daughter now. Oh no, please don't cry. Everything will be alright, you'll see."

"But my brother, what about him? Doesn't he deserve another chance as well?" I sniffled as I wiped my tears then raised my head to look up at Tooth, who smiled gently at me.

"MiM has given him another chance too, his name is Jack Frost and he is a winter spirit." Tooth assured me.

My wings blurred into motion at the news of my brother being brought back to life and I moved to fly away to find him but before I could Tooth gently took hold of my wings. "Easy there Baby, since he had died and was reborn you should give him some time to get used to his new life."

I sighed but silently agreed with Tooth as I let my body go limp. "Alright, I'll give him a few days before I go to him." I promised as Tooth let go of my wings. It would be years until I was able to finally see my brother again as I soon became busy with my job of collecting teeth and delivering money to the children.

"Hey little Baby Tooth are you alright?" A familiar voice asked as the hands that held me opened. I nodded as I squeaked that I was as I stared into my older brother's face, recognizing him even though his hair was now white and his eyes blue.

He smiled at me before setting me on his shoulder as he moved to stand next to North and ended up driving the sleigh while North took down the last black sand horse that had invaded her home. At the sound of my new mother's saddened voice I quickly flew to her in order to comfort her.

It was some time after Jack and the Guardians had chased Pitch off that I found out that my beloved brother didn't remember his life from before he became the Spirit of Winter and therefore had forgotten me.

When I heard Jack say that he couldn't remember his life as a human saddened me but was instantly cheered that he wanted to remember and I lifted off of the tooth holder I had landed on as North declared they would all collect the teeth.

Things started to go downhill from the time we all met up in young Jamie Bennett's room. It started when we lost Sandy to Pitch then we discovered Jamie's little sister, Sophie, in Bunny's Warren when we arrived to help the Spirit of Easter paint his eggs.

Not long after Jack had entered Pitch's lair, I became separated from my brother and was captured by Pitch himself. I found myself trapped in shadows until Pitch decided to use me as a bargaining chip in order to get Jack's staff.

"No Jack, don't." I chirped though I knew he would willingly give up his staff to save me even he didn't remember me, he felt the urge to do whatever he could to protect me. I knew that Pitch would go back on his word to let me go once he had my brother's staff, the same one he had saved me with, but was still angry and pecked him as best as I could.

"Baby Tooth, no." I heard as I was thrown toward a nearby deep crack, calling for Jack to save me before I hit the ice wall and fell down into the crack. I heard him scream, as if he was in pain before he fell down into the crack not far from me.

I soon found out why my brother had screamed when Pitch tossed Jack's now broken staff down into the crack with us. It took a few minutes but Jack regained consciousness, when he did he uttered my name before he crawled over to me and gently lifted me into his hands.

"Sorry, all I can do is keep you cold." He whispered as he sat back on his legs then sighed and closed his eyes briefly. "Pitch is right…I make a mess where ever I go."

Knowing that's not true I stared up at him, my head feathers raising up. I gazed was drawn to his pocket as I felt the familiar tug of a tooth holder and made my into the pocket where I found Jack's tooth holder.

I latched onto the inside of the pocket when I felt him shift his position with another sigh and, once he had stilled once more, reached out to swiftly run a hand over the holder and activated it, which caused Jack to jerk back in surprise before he reached in to pull the holder out of his pocket.

As he looked it over, I crawled out of the pocket and settled on his leg once more. I smiled up at him as he lowered the holder and gazed at me, a question in his eyes. I silently nodded as I placed a hand on the holder, encouraging him to look at his memories.

While he viewed his memories, I moved from his leg to the ground. "Did you… did you see that?" He joyfully asked as he scooped me up into his hands and I shook my head no in answer as he laughed. "I had a family. I had a sister, I saved her." He told me and I twittered in joy that he finally remembered me.

As realization hit him, Jack raised his eyes to the moon that now hung above them. "That's why you chose me. I'm… I'm a Guardian." Jack breathed out in awe before he came to a decision. He set me on his shoulder as he looked around him.

"We have to get out of here." He told me as he picked up both halves of his staff before holding them together. He groaned is frustration as they fell apart but, determined to fix his staff, Jack slammed the two pieces back together as he got to his feet.

I watched in confusion then eagerness as Jack concentrated on fixing his staff. "Alright." I tweeted the minute the bluish light appeared around the crack on his staff, which mended it. With a cheer and a laugh, Jack flew up into the sky once more.

"Thanks Baby Tooth, I owe you one." He exclaimed as we flew back to Burgess, our home, and Pitch's lair.

Jack left to head for the last light, Jamie's, house, he left me behind as he knew Pitch would be after Jamie as well and didn't want me to get hurt during the fight that was bound to take place. It wasn't until after Jack took the Guardian's oath that I found out what caused the odds to tip in the Guardians favor.

When Jamie talked to Jack once he found out we were leaving, I was overjoyed that someone could now see him, besides other spirits of course, and, from the look on Jack's face, I knew I now had a little brother and I wanted so badly to let Jack know who I am.

I vowed to myself that I would make sure to be the one who visited Jamie every time he lost a tooth so I could leave something a little extra when he called out Jack's name before he ran over and tightly wrapped his arms around him in the first hug he had received in three hundred years.

As the sleigh flew back to North's home, I landed on Jack's shoulder where I nuzzled up to him, pressing my face into the where his neck and shoulder met just like I use to when we were both human to let him know, in my own way, who I am.

Jack lifted my off his shoulder and held me up in front of his face, I nodded yes to the question in his eyes and a smile lit up his face as he gently hugged me to him. "How…?" He asked and I simply pointed at the moon.

He smiled up at the moon, "Thank you." He said as I fluttered to his shoulder once more as North flew his sleigh through the portal.
