[The movie that I used as an inspiration is Rise of the Guardians]

"Mommy, is Santa coming tomorrow?" Little Sophie says in a small voice to her mother who is busy doing her official work on the laptop. Suddenly she stops and looks down at Sophie and sighs.

"Sophie, how many times do I have to tell you not to disturb me when I'm working?" Her face conveys no emotion rather she said the above words bluntly. Sophie, who had just turned 9, seems hurt by her words and hugs her teddy tightly and runs out of the room leaving her mommy in regret. 

"Sophie?" Mrs. Bennett calls out but she is already gone. She sighs and continues her work.

***

"Jamie!" Sophie whines punching her brother's arm furiously as he continues to ignore her.

"What's wrong Sophie?" He says in a monotonous voice, still not looking up from his phone. His fingers move hastily on the keypad on the screen as he types a reply to his friend.

Jamie, who is now 15, has changed. Especially after they moved out from their old neighborhood to a new one. He is a grown up now, in the midst of studies and his life he seems to have forgotten about the events that had happened 5 years ago when he with the help of the Guardians and his friends defeated Pitch. Well maybe he remembers but he rather thinks it as one of his childhood dreams.

"Jamie. Tomorrow is Christmas" Sophie says in a sad voice. Jamie just hums.

"Santa will come tomorrow right?" She asks. Her voice full of hope. Jamie's fingers stop moving and he looks at his little sister. He smiles at her and pulls her closer and kisses her forehead.

"Sophie, don't worry you'll get your Christmas present," he says with a smile.

"But Jamie I don't want any presents. I want to meet Santa" Sophie protests.

Jamie's smile slowly fades away and he sighs.

"They don't exist" he mumbles to himself.

Meanwhile, in the land of the Guardians, the sky looks rather gloomy. Jack sitting on the window sill of Tooth's castle, drowned into deep thoughts, watches the clouds.

"Hey Jack, everything alright?" Tooth's voice makes him flinch.

"Oh..Tooth...Yeah everything is fine" he says but his voice sounds rather sad.

"Well it doesn't seem like that," she says letting out a low chuckle.

"You miss him. Don't you?" Tooth places her hand on Jack's shoulder. He looks up at her and gives her a weak smile and shifts his gaze back to the sky.

"He is all grown up now." He chuckles and looks down.

Tooth sits beside him on the window sill and takes his hand into hers.

"I'm so sorry," she says, sadly. Jack just smiles and continues looking at the sky.

'He doesn't believe in me anymore' 1

"Sophie it's time to sleep," Mrs. Bennett says as she enters Sophie's room only to find her daughter already under the covers with her eyes closed into a peaceful sleep. She sighs and walks up towards her bed.

She crouches down beside her bed and looks at the small girl with love. She regrets how she spoke to her earlier in the morning. She caresses her head for a while.

"I'm sorry honey," she says softly and plants a kiss on her forehead. She gets up and switches off the light and leaves the room.

***

In the lands of the Guardians, all the guardians are excited about Christmas but that doesn't seem to be the case with Jack. He doesn't feel right. Suddenly the sound of thunder catches his attention and he looks out of the window only to meet his wildest nightmare.

He is back.

***

There is a sudden knock on Jamie's window. Jamie who is not yet asleep looks at the source. He walks up to the window and squints trying to have a better view. He opens the window. A gush of cold air washes his face entering through the window. He looks around. Finding no one around he immediately closes the window.

He walks back to his study table and settles down. He is reminded of his dream from childhood where he met Jack Frost for the first time. For a second he feels as if it wasn't a dream. But soon he shakes his head and looks at the open book lying in front of him.

"Jamie" he hears a voice, almost inaudible.

Jamie immediately looks around but to his disappointment finds no one. He extends his hand to pick up the cup of warm milk placed on his table. The moment he touches it he flinches. It's as cold as ice.

"Jamie it's me, Jack Frost"

***

"Don't worry buddy... He can't ruin Christmas, he is weak" Bunnymund says trying to console North who looks sad and heartbroken.

"I hope Jack can bring Jamie back, we need him and we have to save him." Tooth says.

"This time Pitch shall be gone. Gone forever" Sandman grits his teeth.

***

"Where are you?" Jamie says looking around the room searching for Jack. His hopes getting high strengthening his belief.

Suddenly he stops, his eyes widen and a smile forms on his lips. He looks overjoyed. Right in front of him, he sees a figure appearing in the mid-air. History is repeating itself. It wasn't a dream after all.

"Jack Frost?" He says in clear confusion.

"Well, I guess," Jack says with a nervous smile.

"Does that mean it wasn't a dream?" Jamie says still amused and trying to process the events. Jack chuckles.

"I missed you," he says and hugs Jamie. "It was never a dream Jamie"

A tear escapes Jack's eyes. He is not able to believe Jamie is back and that now he will believe him.

"I'm so sorry for not coming earlier," Jack says. Jamie hugs him tightly.

"I'm sorry for stopping myself from believing in you," he says.

"Do you believe in me now?" Jack asks as his pulls back from the hug. Jamie nods.

"Yes, I do"

***

Pitch looks around the dark cave he has been habiting since he came back to the land of Guardians. The same place where he had kept the stolen memories and had captivated the mini fairies.

He paces around the room trying to find a way to get to the mortal land so that he could regain his power. Frustrated and desperate to find a way he lets out a scream and a streak of black sand emerges from his palm and hits one of the cracks in the wall of the cave. He looks at the crack which had opened wider after his attack.

Suddenly his eyes fall on something, shinning between the crack, that could be his way out of there. A memory, not just a memory but Jamie's memory. A wicked smirk forms on his lips.

"I'm coming for you... Jamie"

***

"He is back?" Jamie says, a little surprised.

"Yes... And he is after you" Jack sighs.

"But why?" Jamie frowns

"Because it was you... You are the only reason why he can't come back to the mortal world completely. You are an Indomitable Spirit Jamie" Jack explains.

Jamie looks at Jack with a stunned expression.

***

Baby Tooth comes and whispers something into Tooth's ear. Fear takes over her face and she looks pale.

"What happened Tooth?" Bunnymund asks.

"They were arranging the memories... They couldn't find Jamie's memory" she says in a shaky voice.

The color of everyone's face drains away.

"We need to inform Jack"

***

"So I need to go to the lands of Guardian with you to help you guys defeat Pitch Black?" Jamie asks already knowing the answer.

Jack looks at Jamie. He knows it will be dangerous if Jamie gets confronted with Pitch but he also knows that if he doesn't then no one can stop Pitch, especially with the children not believing in Guardians anymore.

He nods. "He is powerful but not as much as you are"

Jamie stays silent. He looks at Jack.

"I'm in. Let's go"

Jack smiles at Jamie, "That's my boy" he says ruffling Jamie's hair.

"Well, I don't think that's necessary"

Both of them turns toward the voice and their eyes widen.

"Long time so see Jamie"

***

"We need to move fast" Tooth screams sitting on the sled with the others.

A huge bag full of gifts can be seen too. North couldn't stop himself from bringing them. It's Christmas after all.

"Tell that to North" Bunnymund rolls his eyes, "who asked you to bring these?" Bunnymund says pointing at the bag.

"C'mon Bunny, it's Christmas" North states. Bunnymund sighs.

"Guys we have a problem," Sandyman says looking at the dark clouds hovering over Jamie's house.

"We're late... he's back"

***

Jack pulls Jamie behind him protecting him.

"It's good to see that you've grown up Jamie" Pitch praises as he moves around the room.

Jack holds his staff firmly in his hand, pointing it towards Pitch. Pitch chuckles, "I know you won't do that"

Jack catches Pitch off guard and strikes his staff in his direction. Pitch staggers back. Taking the chance Jack holds Jamie's hand and jumps out of the now open window through which Pitch had entered the house.

***

"You said he can't come back," Jamie says as they run down towards the main road.

"Yes... I don't know how he got here... Now run" Jack says.

"Not so fast"

Both of them stop in their tracks. Pitch is standing in front of them holding Sophie in his captive.

"Sophie" Jamie says, his voice merely above a whisper.

"Jamie, help me" Sophie cries.

"Leave her!" Jack yells.

"Aww...Sure but what will I get in return?" Pitch raises an eyebrow.

"Whatever you want!" Jamie says.

Jack looks at Jamie not able to believe his ears. He knows what Pitch wants. It's Jamie's life, the only way Pitch can win back his powers.

"Smart boy." Pitch smirks.

"Jamie no" Jack protests.

Jamie ignores Jack and moves forward, towards Pitch.

"Not so fast"

Pitch turns around and his eyes go wide in surprise as North lands on him making him collapse on the ground.

Jack grabs Sophie and pulls her out of Pitch's grab.

Sophie immediately rushes to Jamie and hugs him tightly.

"Who told you they are alone?" Bunnymund hops in the middle.

Pitch struggles and successfully pushes North off him.

"You know you can't defeat me without Sandy" he smirks.

"Well... Then I'm here"

Pitch turns towards the source. A terrified look covers his face. He knows he is doomed. This wasn't a part of his plan.

"Thanks to Baby Tooth... She discovered that Jamie's memory was missing and we knew that was the only way you could get back to the mortal world completely. We weren't sure where it was though but turns out we were right." Tooth smirks.

"Now let's send you back? I'm sure you miss your place" Jack smirks and looks at Jamie.

Jamie nods and looks at Sophie.

"Let's have a little fun, shall we?" Jamie smiles at Sophie.

They hold out their palm pointing it towards Pitch.

"We believe you but... We're not afraid of you"

Their palm starts glowing. Jamie still remembers the night he defeated Pitch and now he is here doing the same. A smile cracks on his lips. A gush of golden sand rushes out of their palms.

The terrified look on Pitch's face worsens. He tries to use his magic but fails miserably. Sandy joins them too.

As the sand hits him he groans in pain. He screams and starts vanishing.

"You can't kill me I'll be back" his last words dies with him. He is sent back to his world never to return again.

All of them look at each other and exchange smiles.

"Well done" Jack pats Jamie's shoulder.

"Santa!" Sophie shrieks with happiness as she runs towards North and hugs him. +

"Merry Christmas!"
