Summary: The Martinez Labs have created a Ghost Portal in the city of Buenos Aires after the success of the Fenton Portal, but the night before it was unveiled to the Argentine Scientific Community, a thief breaks in to see the portal first hand and like Danny is struck by the portal and turned into a half-ghost. What could possibly go wrong when you have a selfish, genius, thief without honor or morals with ghost powers?

The Thief and The Accident - takes place between Memory Blank and Doctors' Disorders.

"This has to be the best idea I've ever had." Sabrina Marquez admitted as she hung from the window pane, but she wasn't going to stop now. Not after she'd spent days stalking the premises to see where the Ghost Portal Laboratory was and the best ways to access it as well as locating the security offices and figuring how many guards she'd have to knock out in order to get in without anything blocking her path. With some difficulty, she scooted to the next window pane and pulled herself over until she was sitting on the edge; with one hand she opened the window and, silent as a ghost, leapt in.

Sabrina had landed just where she wanted. The Ghost Portal Laboratory - base of the Portal Project. Where, according to the media, the greatest astrophysicists, scientists, biochemists, and all the like had been working to create a portal that would lead into another dimension: la Zona Fantasma. The Ghost Zone. There would be a grand reveal the following day, and it was not open to the public: which meant that Sabrina was not invited, no matter how, she was never going to properly set foot in that lab. Emphasis on the properly. If she couldn't see it as a guest, then she would have to see it for herself when nobody was watching – maybe even steal some of the many test tubes in the lab and get to see ectoplasmic residue for the first time. She had drugged the security guards with a heavy dose of a sleep-inducing drug, and had approximated about two or so hours before the effect wore off and they woke up again. But by the time they woke up, she would be long gone.

At first sight, the lab didn't seem special. It was around the size of her classroom; there were test tubes on plain white worktables and machines like lab fridges and Bunsen burners along with the heavy smell of chemicals and metal, but then Sabrina's eyes diverted to the gateway in the back wall of the room. It was hexagonal in shape, with an outline of yellow and black "danger" stripes; it wasn't as big as she had imagined it – the portal being maybe big enough for two tall people to fit through comfortably. Sabrina prowled closer – only walking on the balls of her feet so her footprints wouldn't be so recognizable – and stared at it in awe, taking every detail in.

It was a simple decision and Sabrina walked inside the portal.

She used her hands to guide herself to the end, but halfway there her hand pressed against a big button that started to glow and suddenly the whole portal lit up, the smell of electricity hitting her before the shock.

It felt like her body was on fire, she instinctively covered her face with her right forearm, who received the most damage, while she got electrocuted by over millions upon millions bolts of energy and exposed to the ectoplasmic radiation that leaked through the portal. The electricity ran through her body, making her spasm and shiver inconsolably until Sabrina fell to her knees and then curled up into a fetal position as the electricity continued to hit her – blocking out all thoughts from her head except for the piercing pain.

The energy was eventually drained out on her and Sabrina laid there for a minute. She felt as if she had been doused in acid and then thrown into a fire. Every bone, muscle, and tendon in her body hurt and ached and her right forearm specially felt numb, like it was dead weight. She knew that the security guards wouldn't be there soon - but she feared that the light would attract anyone else in the building or nearby, and so Sabrina grudgingly pulled herself up and very clumsily stood up. Every thought she had before regarding hiding her tracks or going in and out unnoticed were forgotten as she focused on leaving the place before anyone saw her.

Sabrina went back to the window and concentrated on getting out safely, putting one foot in front of the other. By the time she was back at the window ledge, she was ready to faint, the drowsiness made her lose her footing and slip. Sabrina Marquez didn't do so much as gasp as she plunged to what she thought would be several broken bones and maybe some form of paralysis or death. But her body never hit the ground. The world shook back into focus and Sabrina looked around, terrified and then relieved as she realized she was still breathing and not broken into a million pieces. She took her hand to her chest to check for her heartbeat, but was instead greeted by an unusually slow and barely existing beating of her heart.

"¿Que carajo? What the fuck?" she wondered as she stood up more determined than last time and looked around properly.

That's when she realized that nothing had cushioned her fall. And that her feet weren't even touching the ground. Sabrina let out another gasp as she took a few seconds to process it all. She had been: electrocuted by enough electricity to run the entirety of Buenos Aires, exposed to off-the-chart levels of ectoplasmic radiations, fallen from a third story floor, somehow survived that fall, found her heartbeat too slow, realized she was floating.

Once the initial shock had gone away, Sabrina decided to experiment with her new-found ability and test the limits. She tried to settle down on the ground and feel the gravitational strength pull her down but when she was down at the ground again but instead felt like a single gust of wind could blow her away. Having no real track of time, Sabrina made, for once in her life, a rather reckless decision.

She flew up and away towards her house. She headed straight above the clouds and stumbled and barely managed to keep straight – like a bird that was just learning how to fly for the first time. She knew that it was risky and there was a chance that maybe someone saw her – but not quite believing it herself, she was 99% sure that anyone that did see her would merely think they had had too much to drink or was imagining things.

Flying for the first time was an entirely new feeling of being absolutely unbound from everything. Sabrina ran her hand through the cloud below her, feeling the condensed air part before her fingers as she let out a quiet laugh. She was flying. Flying. Flying without any technological help – something humans had tried to do and failed and yet here she was. Alone in the night sky, between the clouds and the stars.

No laws, no weight, no nothing.

She saw her house getting bigger and bigger until she could easily spot her bedroom window, still open as she had left it. With propulsion and a little bit of luck, Sabrina managed to fly into her room and land face first on her unmade bed. Sitting up before completely standing up and stretching, Sabrina ran a hand through her hair as she looked around her room.

And then Sabrina saw her reflection in the mirror.

Her once brown skin was now ghostly pale, almost chalk white; her eyes were no longer brown but a toxic radioactive green; her hair, the braid messed up due to the flying, had gone from a dark brown to a snowy white. Her clothes, which had been a pair of black leggings, a black t-shirt with elbow length sleeves, a black belt, her old worn boots, and black finger less gloves – an outfit perfect for no occasion save for sneaking around undetected in the dark alleyways and abundant shadows that were characteristic of nighttime in the city of Buenos Aires – currently, her clothes hadn't changed that much, save for her boots, belt, and gloves, which were now a light gray. Sabrina stared at her reflection.

How, in the name of all that is logical, was she going to even begin to explain this to her parents?

Fabian and Gabriela Marquez were police detectives.
Sabrina, unbeknownst to them, could be considered a criminal mastermind.

The obvious and so far most logical thing to do: not tell them and act like nothing had happened. God knows how they would react if they heard that all of it started with her breaking into one of the top labs in the city.

Good thing it was five in the morning on a Saturday night and they were sleeping soundly. But that didn't stop Sabrina's mind from racing with a thousand questions per minute. How was she going to change back? Could she change back? What if she was stuck like this forever? A ghost doomed to haunting the city of Buenos Aires? How come she was a ghost and a human at the same time? Her heart was still beating and she could still touch things and stand on the ground – which meant she wasn't completely dead. By all means she should be in a coma or worse. What else could she do? How did this new thing change her whole biology, her biochemistry, her anatomy, her organs, her entire body? What if the scientists at the lab found her? Would they experiment on her? Put her in a zoo cage like a display? Worse, what if they cloned her to make super-soldiers to sell to the highest bidder? Okay Marquez, that's just going a little too far into sci-fi territory. But who am I kidding, the past hour is too far into sci-fi territory!

Sabrina shook her head and stopped thinking. No. They wouldn't capture her if she was clever enough to avoid raising suspicion and getting caught. And she was the cleverest. As she wondered how to get back to her human form, a pair of barely perceptible rings appeared at her waist and went opposite ways to reveal her normal self again. Alive and well, with only a few scratches but no recognizable sign of having gone through anything traumatic that would concern her parents.

She stood still for a few minutes, trying to make sense of everything, not sure of how to proceed.

One thing was for sure: she was going to test this and learn to control it.

...

A few hours later, Sabrina woke up by knocking her head on her bedroom ceiling.

"¡¿Que mierda?!" She shouted as she lost control and landed hard on the floor right next to her bed. Sabrina groaned as she looked up and realized that her elbow had collided with one of the many book towers that littered her room and was tilting slightly towards her. "Fuck." Sabrina quickly rolled to the left and away from the tower and used her bed to lift herself up.

The book tower fell just a second before her mother pushed open the door with her gun in hand.

"I heard a noise." Gabriela cried out as she surveyed the room, until her gaze landed on the pile of books; the detective lowered her gun and gave her daughter a desperate look before sighing. "I'm always telling you to stop towering your books, but do you listen?" Then Gabriela went back to the hallway as Sabrina hid the guilt from her face. "Clean the mess and then come down for breakfast." The thief nodded and watched as her mother closed the door behind her before letting out her own sigh.

"Alright Marquez, you are going to test this new abilities until you can master them in your sleep or else you are going to end up tied to a metallic table by mad scientists. No pressure or anything." Sabrina said to herself as she jumped over the books and hurried down for breakfast.

Downstairs her parents were both eating breakfast while watching the morning news. As Sabrina sat down, she looked at the TV to see the current news and her heart almost jumped out of her chest when she read the title. "Break-In at the Martinez Laboratories Leaves Authorities Baffled." The news' lady went on talking about it. "Last night, two security guards were heavily drugged by what the authorities believe was a group of intruders that broke into the main portion of the lab, where a new experiment – which was to be unveiled today but postponed due to this delay – was in. However, after the staff went through the lab, they have reported that nothing is missing. We are on the story as it develops." The news' outlet switched to another story and Sabrina looked down at her plate of panqueques, feeling uneasy. Her hand suddenly became invisible and intangible and her fork fell to the side of her plate, making Sabrina jump upon seeing – or rather, not seeing – her forearm, she hid it behind her back.

"I'm not that hungry, I'm going to go back to my room." She excused herself and ran back upstairs, clumsily floating some of the way before managing to keep her feet on the ground and close her bedroom door shut behind her. Sabrina took a deep breath and calmed down bfore she noticed her forearm was a visible and solid again.

So these abilities are in a way triggered by my emotions. Emotions/instincts=action; intangibility/invisibility/levitation/etc.=reaction. Now all I need to do is to test them and see if I can trigger them by will. If they are tied to my emotions then I wonder what will happen when I get too angry or sad or happy - would that cause a similar reaction as well?

Sabrina changed out of her pajamas and into a pair of jeans and a somewhat clean t-shirt before lacing up her sneakers and tightly braiding her chest-length hair down her back so that it wouldn't get in her way. She then emptied her school backpack of all but her pencil case and one of her empty notebooks – being the resident class genius, her notes were considered class property by her classmates, and Sabrina didn't want them accidentally finding her notes on this matter when they were looking for her Physics notes.

Back to the pending matter, she needed to find a secluded place to practice and take notes – somewhere where no one could walk in by accident. School, maybe? It was closed on the weekends and students and teachers avoided it like the plague when they could – but she couldn't risk any cameras or janitors or pranksters. Goddammit Marquez, think! Somewhere no one ever goes, somewhere with no cameras, somewhere forgotten…aha! The old library!

The old library was a building that had closed several years ago when some deep-rooted sanitary infractions forced the government to shut it down. Now it was deserted and abandoned save for the occasional students that dared each other to spend the night on Halloween and the rats, the hundreds upon thousands of rats. Satisfied with her plan, Sabrina put on her jacket and slung her backpack over her shoulder as she ran down the stairs and to the back door…only to be stopped in the kitchen by her father.

"Te cierra el banco? Where are you going in such a hurry?" Fabian asked his daughter as she grabbed her set of keys. I'm going to study with some classmates, in one of their houses, nothing out of the ordinary.

"Some classmates need my help with some physics exercises and have offered to pay me for my tutoring services." Sabrina lied. Her parents knew she often played tutor for her classmates in need, hell, they've even suggested she started to charge them. She's lied to her parents before - about going out at untimely hours with Nico or doing some dangerous experiments or the source of some books - but never about something this big and it makes something like guilt coil around her throat and compress her chest. She swallows the guilt as she fumbles to find the key to the gate.

"Ok then, have your cellphone on and loud so that we can call you if something comes up." He reminded her before giving her a kiss on the cheek and saying goodbye.

Sabrina agreed. "Chau papá!" She called over her shoulder as she closed the door behind her and walked to the gate that separated her house from the street. That gate has been faulty since she was eleven, so just inserting a bobby pin or a random key similar in size would do the trick – but to keep appearances in case her parents were watching, Sabrina still used her key to open the gate and closed it shut as she stepped onto the street.

Sabrina kept her bag close to her chest as she walked down the treacherous streets of Buenos Aires and headed to the Library. She dodged beggars, ignored catcallers, and kept her eyes on the sidewalk until she arrived at the old building. Sabrina ducked to the side of the building and walked until she was just below the window of what had been the Librarian's office. Just like the other times she had done it, Sabrina stood on the lid of the trash containers to gain height and propelled herself up, grabbing the window ledge. Still not too confident with her new abilities, Sabrina pushed herself up and managed to sit on the ledge, taking a minute to catch her breath; the thief used one hand to push the window open while her other hand kept her balance, once the lock gave in and the panel of glass swung open, Sabrina leapt onto the floor. Her knees bent as she landed on her feet, rousing a thick layer of dust in the process.

"Very well," Sabrina sighed as she set her backpack on one of the tables and took out her notebook and pen. She wrote down that day's data as she said it aloud. "April 2nd, 2005. Autonomous City of Buenos Aires, Argentina."

"Full Name: María Sabrina Marquez. Age: 14. Date of Birth: July 30th, 1990. After suffering from high-voltage electrocution and exposure to dangerously high levels of ectoplasmic radiation, I have discovered that I am still alive and fully operational – so far, I do not know nor can I estimate the long-term effects that the Accident may bring in the future.

However, immediate side effects of this incident include inexplicable "abilities" such as intangibility, invisibility, flight/ (levitation?), and an "alter ego" of sorts – which consists of my skin tone, eye and hair color changing from that of my usual complexion to pale skin, glowing green eyes, and white hair – I do not know yet if said metamorphosis affects all items of clothing I have on my person at the time of transformation. Theory: this "alter ego" situation will evolve into a Jekyll/Hyde scenario – in which this "alter ego" may develop another (opposite?) personality from my own and lose control of it.

So far my vital signs appear to remain intact save for a few changes such as: -," Sabrina stopped writing and took a good look at her watch, she waited until the seconds' hand was on the twelve and held her breath. It wasn't until an alarming ten minutes that Sabrina felt her lungs softly beg for oxygen – not desperately as it should have been. Sabrina guessed that at that rate, she would be able hold her breath for even longer, maybe she could last twenty minutes, or half an hour!

"- breathing patterns are less frequent – capable of going approximately 10-20 minutes without the need to take in more oxygen. Heart rate patterns also show slower patters, reduced to that of 30 BPM while awake, heart rates while resting and under pressure remain untested – personal guess is that my heart rate while resting is around 5-10 BPM and while under pressure around 40-50 BPM. No superficial or otherwise wounds or injuries."

Sabrina stopped writing and closed the notebook, shoving it and the pen back into her old worn backpack and taking a deep breath to focus on her abilities. She would have to learn how to keep her more obvious and noticeable abilities at bay – she didn't want to go invisible accidentally or phase through a wall when she wasn't paying attention, especially if her parents or anyone else was around to see it. The problem was that as confirmed earlier, her abilities could act up while she was asleep – meaning that if her parents ever woke her up for school or she slept over at Nico's apartment, any of them would see her and from there she could imagine their reactions.

Pushing the image of mad scientists and news coverage away from her mind, Sabrina chose one of her abilities and focused on it – the chosen one being invisibility. Sabrina focused on her whole body and willed it to disappear. Warmth took over her body, starting at her chest and continuing to spread; she looked down and gasped as she couldn't see her body – she closed her hands and opened them again, she could feel her body but she couldn't see it. Sabrina lost concentration for a split second and suddenly her body flickered like a faulty light bulb and not a second after she was completely visible again.

"Progress is slow and disappointing," Sabrina said to herself as took out her notebook and pen again to write down what she had just done. "But progress nonetheless."

By the time her mother called her and demanded that she started getting home right now, which happened around four hours after she had arrived, Sabrina had tried to command her invisibility and intangibility at will – succeeding for several minutes at most – and practiced the metamorphosis, levitating, and flying inside the building at the highest speed she could manage (which was slightly faster than a child on sugar). Grabbing her backpack and shaking the dust off, Sabrina climbed out the window and dared to jump off, using her levitation to land as safely as she could, stumbling a little before recomposing herself and hurrying back home.

Sabrina already appeared tired as she entered her house and hurried upstairs to her bedroom – so claiming she was exhausted from tutoring did the trick and gave her a good excuse to lie down. She spent the next couple hours staring at the ceiling thinking and following countless trains of thought concerning her abilities, her alter ego, the changes in her body, how these changes would affect her on the long run, whether the difference would be noted by Nico or her parents or anyone. Such thoughts plagued her long into the night, as she showered, at the kitchen table having dinner with her parents, and on and on until she finally put an end to the torture she was subjecting herself to and went to sleep with one last thought.

These new abilities could prove themselves useful.

I'm terribly sorry for the wait, but know that I will be re-writing the entire story (though some aspects of the old one like main characters, their personalities, and their involvement will remain untouched) throughout the year - hopefully I won't have to lay off the story due to crippling anxiety and school work this year.

Edit 16/6/2018: rewrite number 2 woohoo!
