He came out in the Antarctica. The right place for his mood.
"This stupid..."
In his anger, he hit a piece of ice. He made a few more ice targets and practiced his bandage whips on them. He thought about Sandy.
"I wonder how long it will take to reach his level of skill..."
"Too long, why do you bother?", replied Pitch, appearing in the cold of the Antarctica.
Jack just turned to him, more annoyed than angry.
"What do you want now?", he asked, "Why don't you leave me alone?"
"I doubt you want to be alone.", replied Pitch. "Your friendship with Mythra, you have a few secrets and I think I know what one of them is. You don't need to hide this from me."
"Why would I want that?", said Jack, readying his whips for attack.
"We both are lonely, outcasts. We both want to be believed in.", said Pitch. "We could help each other with that."
"No.", was all Jack said before he attacked Pitch with his bandages. Pitch didn't expect him to use his bandages already, having seen that Jack isn't good in using them. Pitch was dodging the ice cooled bandages. Ice formed on them, cutting anything in its way. Pitch conjured his scythe and tried to cut the bandages off.
Jack was annoyed by this and used his bandages to grab the scythe. He wanted to pull it out of Pitch's grasp, but Pitch had a similar idea. Pitch pulled on the scythe, bringing Jack to him. He kicked Jack into his abdomen.
Jack fell to the ground and his glamour fell, revealing his Pooka form to Pitch.
Pitch was very surprised. He did not expect Jack to be a Pooka.
"I thought I killed all of your kind."
"So-was I told.", replied Jack before jumping up and attacking Pitch, with his staff. Pitch blocked the blast with nightmare sand. When the two kinds of magic connected, a structure, ice infused with ice, appeared between them.
"Hm, this explains why none of the teeth belong to you.", muttered Pitch. He then looked at the ice-sand fusion. "Are you sure you don't want to cooperate? Our powers go well together."
"I'm sure.", replied Jack.
"Well, I can't offer you your memories... but..."
Pitch showed Baby Tooth to Jack. The small fairy was clearly afraid, puffed up and and cuddled together.
"Give me your staff and I let her go.", offered Pitch.
'If I get her back... maybe I could prove to them that I didn't... but how would I...', Jack thought, I could use the tunnel... I could reveal to them... or make them clear I sacrificed my staff for them. But are they worth it?'
"Time's running, Jack."
"Fine!"
He threw the staff to Pitch who caught it with one hand. Pitch then threw the flightless fairy against ice, she fell into a small split in the ice. He then broke Jack's staff and threw it into the slit with Baby Tooth.
A pain like nothing he ever felt rushed though his body. He fell to the ground, wondering if he now dies too. Sandy confirmed that spirits can die.
He felt how Pitch picked him up.
"You have a habit of interfering."
He let Jack fell into the slit and left.
Jack laid on the ground, the pain got weaker. When it was weak enough, he checked on Baby Tooth. She nestled into his hoodie.
"What now?"
"That is for you to decide.", spoke a voice he knows to well.
He saw Mythra fly down the slit. She was bothered by the cold, but she kneed besides him anyway.
"These Tooth Fairies are so cute.", she said.
"What are you doing here, Mythra?", asked Jack, "Not that I mind that you're here."
"I will not be here for long, I'm no seasonal.", replied Mythra. "That fairy, let her touch the watch."
"Why?"
"Do you really think it is a normal watch?", countered Mythra. "It glowed Pitch's nightmares into the next week." She sneezed. "I need to go. Don't you think you can fix that staff of yours without the watch." And with that, she flew off.
"Wait, did she say I can fix the staff?", muttered Jack.
Looking down, he saw Baby Tooth reaching for the watch. He took it off and held it to her. She touched the center and the watch glowed again. Not like it did when fighting Pitch. Not to mention, it opened.
The surroundings around Jack changed and the was now in a golden city. Looking around he saw Pooka's. He looked around, not believing his eyes. He heard laughter and saw a white Pooka. A Pooka looking like him. His other self played with a few smaller Pooka's. Including one that wore a blue toga of sorts.
The surroundings changed again and he saw himself hopping though the city late at night with the group of Pooka's.
Jack saw an older Pooka approaching the group. He looked like a teenager Pooka, at least he sounded like one.
"Oh, still out this late?", the older one said. "Oh, right, ya orphans. Dirty little orphans."
"What is your problem that you need to insult us?", replied the memory Jack.
"Just saying facts.", the bully said. He then pointed at the Pooka with the toga. "aye, where is that watch coming from?"
"From my mom, before she died.", explained the small Pooka.
Puh, as if any orphan has family watches.", the bully stated. "Ya stole it. Give it to me."
"No.", said memory Jack.
"You little..."
The Bully attacked them and Jack pushed the group behind him. Jack jumped into the air and kicked the bully. Landing on the ground, he grabbed a staff, a staff looking oddly similar to the remembering ones own staff. The memory took the staff and used it to pull the bully away from the orphans away. He took something out of a sack and it looked like a whip. The memory used it to pull the bully to himself and then kicked him again.
The bully left.
The toga Pooka hopped to Jack and hugged him.
"Thank you, Jack!"
"No problem, little sis.", replied the memory. "That idiot, really thought we stole our parents watch. Some people are stupid, don't you thing, Piper?"
Piper nod and then gave the watch to Jack. "I think you should have her, you can protect yourself better."
"Okay."
The watch looked really like the one he wore, but not frost on it. He then looked back to his memory and saw that the orphans, including Piper, started to cry.
"Hey, hey, don't cry!", said memory Jack. "I have an idea, we search a spot to sleep and then I tell you how I met Prince Sanderson Moonsnoozie."
"That never happened!", replied Piper.
"I did, I did! Who do you think taught me how to use whips?", replied Jack. "or this neat little trick?"
Jack put his hands together and and a light formed in them. The light ball flew to Piper's forehead. She gasped.
"You shared a memory with me!" Piper replied, "You still suck with them and the whips, you probably self-taught it to you!"
The surroundings changed again and Jack found himself again in the same town, but destroyed. Looking around, he saw his old self fighting a few things, that while looking like Pitch's nightmares, also looked like rotting corpses.
"Piper? Piper!"
Everywhere they looked was destruction. But they also saw Pitch, or at least someone who looked close to Pitch, but more regal clothed.
Upon seeing him, the memory Pooka froze.
"Oh, Moonlight, the nightmare king."
"Ah!"
The memory ran off to the voice, he recognized it as Piper's voice. Arriving in a cal-de-sack, he saw one of these things approaching Piper.
"Damned Fearling!"
The memory took out the whip and attacked the Fearling with it. The Fearling then attacked him, instead of Piper.
"Piper, run!", yelled the memory, engaging in combat with the thing.
His whip wrapped around it and he slammed it against a building. It turned to dust.
The remembering Jack then saw the Nightmare King appearing behind his memory-self.
"You may not have feared the Fearling, but you will fear me.", the king spoke before striking the Pooka down with his scythe. Jack flinched seeing his own death.
His surroundings turned back to the slit in the cold. Baby Ytooth looked at him perplexed.
"You-You did not see what I saw, didn't you?", he asked.
Baby Tooth just shock her head.
"I-I had a sister, and-and I protected a group of orphans? I-I now know what the watch is, I... I died because of Pitch.", mumbled Jack, trying to understand his memories. "Apparently I met Sandy in my old life? I-I distracted them with a fun story... I think I know what I have to do!"
He grabbed his staff's halves and and held them together. He infused it with his ice powers. The staff was one again and Jack felt the wind again.
He seated Baby Tooth in his hoodie, He then opened a tunnel.
AN: Like I said, big canon changes, including Jack's backstory! Any questions of something is unclear?
