Don't own a fig but my OC

Chapter One:
One-Eyed-Willy and the Quest for the Magic Rubiks Cube

A crackle of thunder rang through the air, and Louise glanced up at the sky just as the first bit of a rainfall started to fall. A sprinkle of rain drops landed on the window, sliding down the arch of the windows while a lightning bolt illuminated her pale and drawn face as she ducked her head back down. Sitting beside her was one lonely suitcase, but it wasn't like she needed more. She huddled close to the ground in her soft black leather jacket and jeans, as the people slowly dwindled out of the airport. Her chestnut hair had long since lost its usual shine, and Louise brushed it away hastily into a sloppy ponytail, her long pianist's fingers already tapping a steady beat faster than the downpour itself.

Her flight had come in a little over a couple of hours ago, and glancing at her watch she could see it was quarter to four in the afternoon. Her brother was over three hours late. Not that she was overly surprised. She had known this was a possibility when she had agreed to come visit him, but she couldn't bring herself to say no. The last time she had seen her brother had been almost a year ago, and since he was her only sibling she could actually stand and had gotten along with during childhood, they were long overdue for a visit.

The phone call had been a bit of a surprise, to be honest. It's not that they didn't call each other often, it was more of the proposition that came with it that was out of the blue. Last time she had heard, her older brother had been working in New Mexico, but with the call came the fact that apparently it was now New York of all places. For him though, she was sure he was more than a little excited. As a kid he had always been one to love being around other people, so living in one of the most populated and busiest cities in the world was probably like his own personal heaven. She was just looking down at her watch for the millionth time that day, adjusting her sunglasses on her nose despite the dim light, when something from the other side of the terminal caught her attention.

"Lu!" A shout resonated through the airport, and she whipped her head up to smile at the speaker, a man in a black suit with little to no personality, not even a colorful tie accented it. However, as plain and serious as the suit was, the look on his face made up for it as a wide grin graced his features, lighting up his brown eyes.

"There you are, Phillip, you silly man!" Louise said to her brother as he pulled her into a giant bear hug. "I thought I'd be the last person here!" She explained giving him a knowing look.

"I know, I know, I'm sorry! Work had me held up and Fury can be pretty, well, infuriating." He answered laughing, taking her suitcase from her hand, and leading her to the parking lot. "That didn't mean you had to wait for me, Lu." He added sternly, reminding Louise of the bossy older brother he was in their childhood.

"I don't exactly know where you live. It's a good thing you came now though. My plane arrived three hours ago, the attendants and workers were starting to give me strange looks." Louise responded, rolling her eyes. "If you really wanted me to visit, you would have been here on time." She quipped.

"If I didn't want you here I would've come earlier, so I could try to convince you to get on the first return flight." He said, as they finally arrived at his red flashy car, Lola, if she remembered correctly. "Not that it would've worked."

"No, I suppose it wouldn't. At least it hasn't in the past." She joked, sliding into the passenger seat as he put her bags in the trunk. "So where are we headed?" Louise asked him, not missing how he stiffened his composure at the question.

"I'm afraid we're going to have to take a bit of a detour from our original plans. Instead of going first to the house, we are going to have to make a quick stop at work."

"Captain Hook needs you that much?" She questioned, pulling on the puppy dog face that always seemed to work as a child. Phil gave her a look, a small smile twitching at the corner of his mouth.

"That's not going to work on me. Lu, you're not a 6 year old anymore." He said, clearly amused.

"Yes, that's right dear brother, I'm glad you haven't missed out on the past thirteen years." She answered batting her eyelashes at him, pretending to be bashful, causing him to laugh.

"I thought you were 18?" He asked suddenly, somewhat bewildered. It was now her turn to laugh, she had forgotten how bad his memory was. Or how long it was since they had last celebrated a birthday together.

"My birthday was six months ago, Phil. I invited you... remember you said you had to deal with something in the south western states." She reminded him, and his face fell slightly as she recalled the incident for him. His work was always getting in the way of things one way or another, may it big family stuff or just quality time with his sister.

"Right." He muttered under his breath clearly feeling quite guilty, much to Louise's amusement. "I'll have to make it up to you somehow." He told her earnestly, but she doubted it. In the past few years she had heard that specific phrase an awful lot, and he was yet to completely fulfill his promise. However, that didn't stop her from requesting anything.

"I have the perfect idea! How about if we just don't go to your work today?" She dead panned, her expression completely serious. She had learned from past encounters that Director Fury, or Captain Hook, or One-Eyed Willy, or Major Constipation Man (best not to ask about the last one), really didn't like to have surprises, and she had no doubt that her brother had probably sprung this on him so that there was less of a chance of her being forced back onto a plane by men in black. She doubted that this was going to be pleasant so her somewhat joking attempt at asking was a but more hopeful than she let on.

"Nope not that, sorry Lu." He responded, and she slumped back in her black leather seat, staring gloomily out the window as they drove through the streets of Manhattan.

"On the subject of your work, why are you working in New York of all places?" She said, turning to him, giving her brother her best eyebrow raise. "I mean, not that I'm complaining but why the urgent need for me to suddenly come visit you in the big apple?" Louise added, and her brother stared at the streets, seemingly determined not to give anything away.

"Well, I ah missed you." He answered, giving her a smile that quickly slid off his face, when he caught her scowl. "Fine, fine, Fury wanted me to contact you, he has something to discuss with you that might be in your area. Actually I'm positive it's in your area." He explained somewhat defeatedly, before adding quickly as he caught her look of disgust and barely hidden surprise."Not that I didn't want you to come! It's just I didn't really want you wrapped in all of this." She sighed dejectedly, shaking her head at her brother. He may say he had missed her, but chances are he wouldn't have called her and asked her to come unless the almighty director suggested it. Which wasn't likely. Mad Eye Moody hated her! Why would he want her there, or really anywhere on this job?

"And what exactly is," She air quoted, "This?"

"You know that man we found in the ice?" She nodded, of course she did. Her brother was the ultimate Captain America fan, so naturally when he had been found it had been impossible for him to keep quiet about it. Even if it was a supposedly national secret. When he found out he was like a small kid on Christmas. "Around the same time we found him we found this cube of energy, something called the Tesseract. So, anyway we were working on it to figure out what it's all about." He hastily said, hands now gripping the steering wheel in a vise like grip.

"You were working on it? As in past tense, as in no longer doing so?" She inquired, picking up on the very thing he didn't want her to, but then of course she did, she could spot a lie a mile away let alone a lowly change of tense.

"Yes, we were. A man, or rather god, called Loki, took it from us. He went so far as to turn a handful of our best agents rogue, and destroy our base in order to get what he wanted. And he hadn't even been there for more than ten minutes."

"Sounds like he knows how to make an entrance."

"You could say that. If you asked me, he is just a spray of hair product short from a full tilt diva, not to mention his crazy ideals. I mean, god dammit, the man seemed to believe that it was his birth right to try to kill us all! And I don't doubt he would." He said through gritted teeth, his anger visible in his tone and body language. "He came from a magic portal of sorts and had a spear that glowed, which he used to slice and dice anyone who got in his way." Phil spat, his eyes dark. This made Louise frown, he was clearly still having slight flashbacks from whatever had happened, but she chose not to ask for the specifics.

"And what does this have to do with me?" Louise was never one for violence, so the idea that a man who was clearly losing his marbles and had no problem killing to get his way, could somehow be her "area" was preposterous. Unless her brother was referring to something else?

"You specialize in highly dangerous energy forms, I guess Fury figured this would be right up your alley." Louise scowled at that, throwing him a bewildered look.

"Specialized, Phil, specialized." He glanced over at her studying the way she stared straight ahead.

"You could go back you know, to Stanford. Finish your degree..."

"And leave what I have now? I'm happy where I am, Phil." She stated, and her brother sighed.

"Are you? I mean you hack rogue organizations for a living." Louise smiled briefly, before her brother added, "And some not so rogue ones too. You know, that drives Fury nuts."

"That is precisely why I do it. He wouldn't have that problem if he invested in Stark Tech."

"So you and Tony could hack him without all the hassle?" She nodded. "It would be safer if you went back to nuclear energy. I mean, the only reason you left was because-"

"I really don't want to talk about it." She snapped before he could finish, she'd always been touchy about that subject, but she refused to talk about it even to Phil.

"Okay. But anyway, don't worry. You won't be the only one working on the project, Natasha is trying to get Dr. Bruce Banner on the project, and Tony Stark may or may not show up, you know how he is." He added, and she bit back a laugh, boy did she know how he was.

His girlfriend Pepper was fine in her opinion, but her and Tony got a long a little too well for anyone's comfort. The sarcasm running through an area that had both Tony and Louise was apparently dangerous. She had visited him in California about two months ago, and boy was that an adventure. Not only had they single-handedly almost destroyed his lab, they had also managed to really piss off Pepper and Rhodey when they publicly mocked the secretary of defense rather rudely. Not that they planned it, they weren't even in the same room as each other. Oh well, great minds think alike. Needless to say, Fury must have been just short of wildly desperate to come for both of them for help.

"And Banner, has he actually agreed? I thought he was pretty far removed. I mean, I got to know him a bit him two years ago when I met him after... I left college." Due to having a brother like Phil, she had always been interested in the super soldier project, so when she overheard a conversation (argument, really) between her brother and his boss about a new attempt gone awry, she had gone looking for more information. Finally she found him in Brazil, and she anonymously sent him supplies and information to where his enemies were, before going to meet him at Culver University. Thankfully, they still stayed in touch.

"I don't know yet." Phil said truthfully, "I left before Natasha could get back from her mission to bring him back to help us."

"Speaking of which, back where? Seeing as I don't really have much of a choice in this do I?" Louise asked, already knowing full well the answer, and Phil shook his head solemnly.

"Sorry, Fury really wants you." She scoffed at that. Her and Commander Stick-Up-His-Ass hadn't gotten along very cordially any of the times they had met. It was part of the reason her and Tony got along so well, it was actually how they met. They had both managed to anger Fury around the same time. Tony for flying into an oversized donut, and Louise for messing with the calibration of one of his jets. Oh and then stealing his eye patch.

"I bet he does! But one does not simply get the best hacker in the country without a little hassle." She stated smugly. Her brother's brow twitched with worry.

"Lu don't go doing anything stupid. It's bad enough we'll have Stark to handle, we don't need you too." He requested, knowing there was probably no hope, his sister and the billionaire philanthropist got along famously, and Phil knew that better than probably anyone. Poor Phil was often the but end of their jokes, even if Tony hadn't known his first name until supposedly a couple of days ago. "And plus where we're going, you won't have room to blow up a corridor, or flood the toilets."

"Oh really? Where are we going?" She demanded, what place was there where a little harmless trouble couldn't be under way?

"You'll see." Louise couldn't help but feel a little apprehensive, her brother looked way too happy.
