Chapter 1: Medical Student

Past

Central Park, Manhattan

"Come on, Jack!"

"Alright, Emma. I'll be there." Jack smiles at his little sister rushing towards the frozen lake ahead.

"Be careful." Looking over his shoulder, Jack replies to his mother.

"We will." He said before he turns around to join his sister on the frozen lake to ice skate. Carrying his pair of ice skates sith him, something caught Jack's attention and he steals a glance to his left, catching a gleaming light coming from the snow covered fort nearby the lake. The brunette decided to find out about the light but before then, his little sister's voice catches him off guard.

"Jack! Come on! Where are you going?" Emma yelled through her hands as Jack looks at his sister gliding at the center of the frozen lake. Stealing a glance to the gleaming light, he changes his direction to head towards his sister and promptly play with her.

Once he steps onto the edge of the frozen lake, Jack decided to wear his ice skates while keeping an watchful eye towards his sister that was skating around the frozen lake. But as he tried to wear the skates, he heard Emma's scarred voice.

"J-Jack!" Looking up, Jack's eyes widen at his sister standing on cracking ice.

"The water's not frozen yet?" Jack thought in surprise before he stands up, ignoring the wear of ice skates as he approaches his little sister in slow strides. "It's okay, it's okay. Don't look down, look at me.

"Ja-Jack, I'm scarred…" Emma said as she glances down before looking up at her brother who looks at the ice below her cracking more.

"I know, I know."Jack admitted before he looks down, seeing the ice below him starting to crack. "Bu-But you're gonna be alright." He reassured him with his comforting hands waving at her in reassurance. "You're not gonna fall in." He added. "Uh…"He looks down for a second in thought before a playful smile stretches across his face. "

We're gonna have a little fun instead." He extends his arms apart.

"No, we're not."

"Would I trick you?"

"Yes, you always play tricks."At this, Jack chuckles before he stretches his left hand at her. "Aha, well, not-not this time. I promise, I promise you're gonna be, you're gonna be fine. You have to believe in me." Jack said to his sister who stared at him. "Well, you wanna play a game? We're gonna play hop scotch like we play every day. It-It's as easy as…" He said as he put his right foot to the left which causes the ice to crack under it. "One," Seeing this, Jack pretended to fall as Emma let out a laugh, calming him down."two,"Jack continued putting his other foot to the left before stepping another quickly. "three." Grabbing a odd looking staff laying on the frozen lake next to him, he focuses on getting his sister from falling into the water. "Alright, now it's your turn."He said as Emma started stepping first. "One, two…three!" He counted before he extend the staff and pulls his sister by the hook of the staff.

Looking at his sister laying down across him, Jack immediately jumps away to his right, avoiding the ice shattering below him seconds before. Shaking his head, Jack stands up and his eyes was met by his sister's. With a smile, he approaches her just as Emma runs towards him and they both hug each other.

"Are you okay, Emma?"

"I'm okay." Emma responded as Jack sigh in relief over her left shoulder. "Thank you, Jack."

"What are brothers for?" He asked before something catches the brunette and Jack looks up at the shiny light gleaming at him. He squinted his eyes towards the edge of the frozen lake and his eyes trailed along metal box visible from the snow that covered it. But just as he stares at it, he watches as the snow around it fall off, revealing digital red numbers counting down to zero. His eyes widen before everything exploded.

Present Day

New York City

Night

Near the sidewalk of a junction was the bustling noises of vehicles that were stuck in a traffic for the last hour. Then begins the honking noises originated from every driver present that were beginning to get more frustrated at how long the traffic last.

"Sorry, sir. But I'd think this traffic will not let up." The taxi driver said to his passengers sitting behind the back seats.

"Do not worry. New York is always bustling with traffic jams." The passenger stated in amusement as his wife stifle a laugh next to him.

"Are you from here, sir?"

"No. We're just visiting for business. And also, this is my wife's first time going here."

"Really, madam?" The taxi driver glances at the brunette woman sitting next to her husband.

"Yes. Unfortunately." The woman in question smiled.

"Unfortunate? You're more than fortunate to visit this city and considering that this is your first time here—Welcome to New York City! It's a pleasure to make your acquaintance." The taxi driver smiles and tip his head towards the couple as the woman nods. After that, the taxi driver looks forward, seeing the traffic slowly letting up and he drives the taxi forward slowly. Just as he stops once again, the taxi driver asks to the couple. "Well, if you don't mind me asking; what is your business on coming here? It must be important if your work is held in New York."

"We don't mind at all. We came to visit a friend at one of the hospitals in New York."

"A friend? Is he a patient in that hospital?"

"No, he's the director of the hospital." At this, the taxi driver smiles.

"The director? Is the director's name Dr. Nicholas North?" Surprise etched onto Adgar's face at the mention of the name.

"You know him?"

"He is famous throughout New York. I don't think anyone doesn't know who he is in this city that never sleeps." The taxi driver chuckles to which Adgar smiles in return.

"I suppose that is true." Adgar nods before feeling the taxi surge forward.

"I hope we can get to the hospital before we sleep." Idun said turning to her husband.

"That's normal, madam. That's the unfortunate side of being in New York." The taxi driver replied as Idun grabs onto her husband's right hand and bring them onto her lap before she leans her head against his right shoulder.

"Then will you not mind if I take a nap? The trip over here took a toll on me." She asked Agdar.

"Why would I mind?" Agdar smiled as Idun smiles in return before she closes her eyes.

York Ave

St. North Hospital

"Where are you going, Jack? Shouldn't you be on duty with me?" A teen with tousled brown hair asked his white haired friend. The two of them stood at the entrance of the hospital and they both wore white coats indicating their involvement with the hospital.

"No. There's nothing to do here at this hour." The white haired teen named Jack turns towards his friend, Hiccup. Putting down the suitcase next to his feet, a pair of headphones hangs around his neck as he looks at the worried looking brunette.

"But what if something happens?"

"You can call Rapunzel. She'll take care of it like any patients she have treated." The white haired teen smiles at his brown haired friend. "Anyway, aren't you here? The hospital will be in safe place if you're here, Hiccup."

"But you're our senior, Jack."

"In age. Both of us know that I'm just a medical student. Both Rapunzel and you are interns. Technically, you're my senior." Jack explained smirking.

"That's true. But…" Hiccup trailed off before white covered his sights. He pull off the white coat on top of his head and he looks up to watch Jack turns around and waves back at him.

"Hold down the fort for me. I'll be back tomorrow." Jack bid taking his suitcase while wearing his blue hoodie on top of his head and left the hospital while leaving Hiccup staring at him.

"Huh…" Hiccup sighed before an arm wraps around his left arm and he looks at his left to see his girlfriend looking at him.

"What's wrong?"

"I don't think I can patrol this alone." He said unconfidently as he holds up the white coat in his hand owned by his friend that left. "I just entered internship two months ago. I barely practicing patrolling for a month and I was with Jack that time." Hiccup sighed in slight frustration.

"If you said it like that, then why don't I accompany you instead?"

"What?" Hiccup asked in surprise. "But you have your own duty to do, Astrid."

"I did my rehabilitation duties for the patients. So as you can see, I'm free." Astrid smiles before raising an eyebrow with amusement splattered on her face. "Or you would you want me to rehabilitate you into shape?" Hearing that, Hiccup gulps nervously before shaking his head.

"Good. Now then, where do we start first, Intern Hiccup?" Astrid asked amusingly as Hiccup looks at her for a moment before letting out a small smile, thankful for her presence.

"We'll start by walking around the hospital. And I have to return this," Hiccup gestured to the white coat he's been touching. "to the locker."

"Lead the way."

"I'm not sure if you mind being lead to the boy's lockers."

E 71st St

Putting his right hand into his hoodie pouch, the white haired teen stroll along the pavement in silence. The only sound that he could hear was the sound of his footsteps. After a while, the teen pulls out his hand from his pouch and tugs onto his headphones to his ears. The small wires that were connected to the headphones traces towards the pouch the teen hid his right hand. Just as he pocketed his said hand, he press the play button of his smartphone. Suddenly, his eyes turns sharp and a smirk stretches across his lips as his imaginative mind changes the environment around him; into an operation room.

Garbed in the usual operation uniform, Jack looks down at his patient before asking to the person across the operating table. "How's his blood pressure?"

"Stable."

"Brain waves?"

"It's also stable."

"Good. We can start the operation." The moment he said it, he extend his right hand to the side as his assistant stood next to him tasked with handling the operating tools. "Scalpel." Hearing the word, the assistant grabs onto a clean scalpel and gives it to him. Spinning the scalpel in his hand once given, Jack expresses a smirk under his face mask before he proceeded to cut the right leg skin. Once cut, he puts the scalpel onto a given tray and extends his hand towards his assistant. "Retractor." He clutches the retractor in his hand before attempting to stretch open the cut skin to delve deep onto the problem hidden inside the leg.

After situating several retractors, his eyes then saw the problem at hand; a fraction of the bone was stabbing into the blood vessels causing internal bleeding in the leg.

He looks up at the assistant across from him, "Prepare the suction." He stated as the assistant nods before readying to prepare the intended tool. Looking down at the patient, he extends his hand to the second assistant next to him. "Forceps." He was handed the forceps and plunge down the tool inside the opened skin to retrieve the fraction of the bone and put it into another tray beside him. But at the action, it immediately causes blood to rise up in the opened skin and Jack looks up at his first assistant who begins suctioning.

"The only remaining left is to…reconstruct the bones, nerves and torn—" Just before he finishes his sentence, Jack's eyes snapped back into reality as he heard a catastrophe crash nearby followed by screams.

1st Ave

Looking up within his hood, the white haired teen immediately rushes forward to the scene with his suitcase. Arriving at the crime scene, his eyes widens at the horrendously wrecked cars against each other. His eyes then follows the car situated furthest away and he trailed off the leak oil from the said vehicle.

Looking at the crowd at his right, he shouted, "Someone attend to that man! I'll check on the others!" Jack pointed to the unconscious man sitting on the driver seat nearby before he sprinted towards the wrecked taxi a few feet away from the said car. During his sprint, he shouted once again to everyone who was listening. "And someone call an ambulance!"

Once arriving at the wrecked taxi, he kneels down and looked inside the driver seat, locking his eyes with the taxi driver and his passengers. Gritting his teeth, Jack immediately sets on pulling the taxi driver but noticed that he wore a seat belt strapped to him. Putting down his suitcase, the teen opens it to withdraw a pair of scissors and proceed to cut the seat belt. Once cut, he quickly pull out the unconscious taxi driver.

Putting down the taxi driver on the sidewalk nearby, he rushes back to the trapped passengers. His eyes trailed off the bleeding on both of the passenger's heads and he grabs onto the handle of the wrecked door; pulling on it a couple of times but it does not budge. "Come on!" Jack pleaded as he put his effort on pulling the door. Suddenly, the door cracks open and Jack slowly opens it wide enough for him to reach for the male passenger. Pulling out the scissors in his hoodie pouch from before, he cuts the seat belt on the passenger and pulls him out with little difficulty. Carrying the said man in his arms, he runs towards the same sidewalk and lay him down next to the taxi driver. Turning around to retrieve the female, Jack was stopped by a grip of his right hand. He turns his head around to see the male passenger conscious.

"…Please…save my wife, Idun…" He pleaded as Jack nods before he rushes towards the taxi once again. And as he arrived to the opened wrecked door, Jack put his knees down on the back seat to approach the female passenger closer.

Meanwhile, a couple of teenage happened to walk by and they noticed the scene. One in particular, snickers at the scene before rolling his eyes in ignorance and throws his cigarette on the road which happens to be close to the oil leak from the taxi.

"What?" Agdar watches in slight difficulty at the light of fire visible in his sights and it was approaching the taxi via trailing the oil leak. "Idun…"

Carrying the woman in his arms, Jack proceeded to retract from the taxi until his eyes captures the fire approaching the taxi. Eyes widening, the white haired noticed his suitcase laying nearby at the door of the driver seat in which the fire was approaching. Gripping onto the woman's shoulder, he rushes forward to grab the suitcase, unaware of everyone and Agdar watching the scene in shock.

"What is he doing? Is he crazy?"

"Get out of there!"

"What are you doing?!"

"Idun!" At the moment Agdar shouted his wife's name, the taxi exploded sending everyone to shield away from the explosion. "Idun…" In a state of shock, Agdar attempted to stand up and rush towards his wife to see if she was alive. Unfortunately, he couldn't as he felt weak to his knees. Tears appearing over the corner of his eyes as he looks down shameful, unaware of the hooded teen approaching from the after smoke of the explosion.

"Wait! It's them!" One said within the crowd nearby Agdar and the taxi driver.

"They're alright!"

"Huh?" Agdar looks up and his eyes widen to see the hooded teen kneeling down in front of him and presented to him; his breathing wife. "Idun?"

"Can you move away?" Jack asked as Agdar look up at him. "She's hurt." He said as Agdar look at his wife's right leg, seeing blood stained the skirt laying over it.

Nodding to him, Agdar backs away just enough for Jack to put Idun down on the ground. He then watch the hooded teen grabs onto the edge of his wife's skirt and rips it apart, much to his surprise.

"What are you-?!" Agdar was cut off as he saw the deep cut over his wife's right leg.

"I suspected as much." Jack scanned the damage. "If she does not get any medical attention now, she wouldn't be able to walk anymore. From what I see here, we could possibly assumed that one of her nerves had been cut and possibly her bone had been fractured."

"Wha…How?" Agdar asked before he recalled that his wife was sitting behind the driver seat which was close to the collision. "She sat where…"

"The collision occurred; so she took the brunt force of the impact the most as well as the taxi driver." Jack looks behind Agdar at the unconscious taxi driver. "There's no other choice than to operate." Laying his suitcase next to him, Jack opens it up to reveal surgical equipment much to everyone's surprise.

"Are you a doctor?" Agdar asked looking up at the hooded teen who looks down in a pause before answering him.

"A medical student."

"What? A medical student?" One man in a suit asked with a raised eyebrow amongst the crowd nearby Jack. "Then you haven't your medical license yet. How can we trust that you'll operate safely? Can't we wait for the ambulance to arrive?"

"Yes, that's right. It would be totally safe to let the professionals do it."

"A medical student operating? That is absurd!"

Hearing the insults, Agdar looks upon the hooded teen and doubt was evident on his face. But before he could voice out his voice, the teen drags down his headphones and let his hood down to reveal freshly white hair from within the hood and a pair of deep sapphire eyes. Agdar watches as he turns to the crowd and replied,

"Then do you want them to amputate her leg instead?" At the sudden question, everyone was silenced. "Professional or not, she needs treatment now. The ambulance will not arrive in time. If they can't come, should we do nothing?" Jack asked frowning with a slight glare, silencing everyone from even trying to reply back. Turning to Agdar, Jack asked. "Do you want your wife to walk again?" He asked as Agdar did not hesitate to nod. "Then…50,000$."

"What? Are you kidding me? That's a crazy amount!" The same man in a suit voiced out. "He can't possibly pay that much for a lowly medical student like you."

"That much is not worth this woman's life!" Jack replied back to the man. "Anyway, it's his decision, not yours." He added as the man in the suit bare his teeth in frustration. Turning to Agdar once more, Jack ask again. "50,000$. Can you pay for it?" He asked without hesitation as Agdar looks at him directly in the eye before he looks down at his wife. After a moment, he nods and nods towards Jack.

"I'll pay." At this, Jack smiles.

"Good. But since I don't have any anesthetic, I'll make it quick before she wakes up. Are you alright with that?" Jack asked Agdar who nods. Looking down at his patient, Jack grabs onto a pair of surgical gloves from his suitcase and tied them on Idun's right thigh to stop the blood flow. Grabbing onto another pair of surgical gloves from his suitcase, the white haired teen wear it as everyone watches the spectacle while some started recording the event. "We can commence the operation."

Pulling out a scalpel, Jack twisted it around before slicing the part of the skin on each side of the cut. He then put it away before grabbing a pair of retractors and pull the opened skin. He then accessed the damage before he started to pull a pair forceps and another scalpel and immediately beginning the real part of the operation.

Just as he started operating, Agdar watches his wife and hoped that she wouldn't wake up since she would instantly feel the pain even if she couldn't feel her right leg. Glancing up at the white haired teen, Agdar noticed the drops of sweat visible on his forehead and he retracted a napkin from his pocket pants to wipe them. The white haired teen did not react to the gesture and continued to operate in deep focus.

Grabbing a bunch of cotton balls from his suitcase with his forceps, the teen wipes the blood that are visible to reveal the fracture of the bone. Furrowing his eyebrows in concentration, the medical student immediately pull out a few forceps to clamp onto the damaged blood vessels. "This is it…" Jack thought as he looks down at the clear view of the cause of pain. "I can do it!"

Meanwhile, Agdar's eyes widen in awe at the surgical skills of the proclaimed medical students; promptly his scalpel skills that were quick and decisive. "Is he really a medical student?"

Moments passed during the operation, and while everyone was tempted to leave, they were also fascinated by the display of the medical student, prompting them to stay and watch him instead, prompting everyone to watch how quick his hands were moving.

"How can his hands move that fast?"

"This…is an act of God itself."

"Amazing…"

Everyone was awed as they watches the medical student worked his way on operating his patient. Upon every single minute, everyone was hoping that the operation would be successful while some were hoping that it would not due to how inexperienced he is as a medical student. But their doubts wavered as they watches how skilful and fast he is.

Suddenly, everyone watches the white haired teen grabs a suture and a pair of scissors to suture the torn nerves, tendons and lastly, the opened cut of the woman's leg. As Jack puts down the pair of scissors and suture onto an empty space of his suitcase, he sighed in relief. "The operation was a success." At that, everyone cheered and Agdar looks at him with a smile.

"Is it really?" At his question, Jack nods and looks at his watch secured around his right wrist, looking in relief that he did not waste the operation any longer.

"Yes. Now she needs to recuperate."

"…Thank you, Doctor." At the name, the white haired teen blushes in embarrassment before waving his hand in denial.

"D-Doctor? I-I'm not a doctor. I'm just a medical stu—"

"No, you're not. You're a doctor." Staring at the man before him, Jack replies.

"…T-Thank you, sir." Jack smiles genuinely before registering the blood on the side of his head. "Since the ambulance isn't arriving yet, we should clean you up just in case you will faint from blood loss, sir." He stated in amusement as Agdar touches the line of blood at the left side of his temple.

"It seems you're right. I feel lightheaded."

"That's one of the symptoms of blood loss."

"Will this going to cost me?" Agdar asked with an amused smile.

"I'm only doing as a first aid. And it goes with your wife's treatment cost. So no. It doesn't cost you nor the taxi driver." At the mention of the taxi driver, Agdar looked surprised.

"You're going to help him too?"

"After I'm done with you, I'll treat him next without any cost whatsoever." Jack grins as Agdar smiles wholeheartedly.

"…Thank you." He thanked as Jack started treating him by removing the blood from his temple and suturing the wound together without anesthetic.

Seeing the near visible suture marks, Jack nods at himself before working himself towards the unconscious taxi driver laying on the ground behind Agdar. While he was busy treating the taxi driver, Agdar kneels down next to his wife and holds her right hand in his hands.

"We're going to be all right. You're going to see Elsa and Anna again." Agdar reassured her before he steals a glance at the white haired teen working on the taxi drivers wound. A smile let up on his face as he recalled a certain elder daughter that has the bright color hair similar as the teen albeit platinum blonde.

"…Ad...gar?" A weak voice called as Adgar looks down at his wife conscious.

"Idun? Are you all right?"

"What…happened?" Idun asked staring weakly at him as Adgar wears a reassuring smile.

"We got into a car accident. Both of us including the taxi driver got hurt but you were hurt the most. Luckily, there was a doctor nearby and he treated you completely. He's now treating the taxi driver." Just as he said, Idun glances at her right and she saw the white haired teen's face that was concentrated on treating the said driver by suturing the wound he had on his right arm.

"He reminds me of…" Idun stared off at the bright color of the teen's hair. "Elsa." A weakly laugh escaped her mouth as tears covered the side of her eyes. "My baby…"

"Don't worry, Idun. We'll be back for her, for both of them; Elsa and Anna." Adgar reassured as Idun slowly nods.

Suddenly, the sound of an ambulance could be heard throughout the street and everyone look up at the ambulance driving through the sidewalk nearby them.

Cutting the suturing string with his scissors, Jack looks at his work before nodding to himself. Sighing in relief, he gathered up all of the used surgical equipment and put them into a safety plastic reinforced air bag before putting them into the empty space of his suitcase in which he tied them down with a safety belt of his suitcase. The white haired teen stood up to be greeted by a couple of paramedics running towards him.

"We'll handle them." The paramedics proposed as Jack shakes his head to them.

"These three have been already taken care of. Take these two to the hospital first to get a check-up of their conditions." Jack pointed out to the right where Adgar and Idun were. "I already gave them first aid and so was him." He pointed to the unconscious taxi driver below him.

"Who are you, boy?"

"Do you want to waste your time by knowing my name?" Jack asked with a serious expression as the paramedics flinch at his tone.

"Don't overstep your boundaries, you two. He's with me." A messy died grey haired man stated walking up to the two. At the appearance of the said man, Jack let out a grin and hold up a hand in greeting.

"Bunnymun—" A hand clasped to his mouth as the grey haired man glares at him through the corner of his eyes.

"If you want to live, you should consider not telling anyone my name. Aster is enough, got it? Frost?" The man muttered under his breath.

"Fine, Aster." Jack's voice was muffled as he rolls his eyes before smiling at the man to which the man, Aster retracts his hand from his mouth.

"So what happened?" Aster asked as tribal tattoos could be seen stretching across his exposed arms.

"Car accident. Three with light injuries, one's in critical; slight fracture of her right leg bone. But I already taken care of the three, including the critical. There's another one who's across the street, unconscious. But I suspect that he does not have any critical Injuries when I looked at him."

"Alright, Frost." Aster let out a small smile at the explanation before he looks at the two paramedics that flinches from his serious stare. "Go and load those two as the boy says."

"Right on it, sir!" The two paramedics shouted before they load off the stretcher from the ambulance towards Agdar and Idun. Once the two gently picked up Idun onto the stretcher, they load her up into the ambulance with Agdar in tow.

Seeing everything was in order, Aster turns to the white haired teen. "You're coming?" He pointed behind towards the ambulance.

"No. But I'll come back after I picked up some food from the nearby cafe. I have to check up on my patients, correct?" Jack asked with a smirk as Aster shakes his head before nodding at him. "Anything you want?"

"Get me a healthy drink."

"Carrot juice? On it." Jack nods as Aster rolls his eyes before turning around to climb into the ambulance. Seeing the ambulance drove off, Jack looks at another ambulance driving into the scene and he pulls up his hood and headphone before silently walk away from the scene with his hands in his pocket. A satisfying smile stretch across his lips as he goes to the nearest cafe.

Meanwhile driving through the streets towards the hospital was the ambulance carrying Idun and Adgar. Inside the back of the ambulance, one of the paramedics did a quick check up on Idun before shockingly exclaimed.

"This is not a first aid…This is not it at all…He operated on it and managed to make everything all right. He managed to make her leg move despite the slight fracture in her leg. But how…? How in the world…?" The paramedic asked in awe as Aster smiles to himself while he drove.

"Looks like you made your debut, Frost."

Unfortunately, this is the end of the first chapter. I hope that all of you are happy with the results of my hard work. I know it has errors that I can't find but I am grateful that I finish. Without further ado, I will see you next time!
