Hi everyone! This is my first fanfiction and I'm really excited. I loved Batman V Superman and thought that Lex needed some love and this is a chance to really delve into his past. This is my own interpretation of how these characters would interact in new situations e.g. Lex in a relationship, Bruce having a sister.
There is SPOILERS for the movie, so if you haven't watched it this will spoil the story as it surrounds the plot of the movie.
Hope you like it.

Disclaimer: I don't Batman V Superman or any Dc characters. I only own Thea.

CHAPTER 1 - THE INHUMANITY OF GOTHAM

"Downstairs to your left, you will find the main office."

Althea Wayne stares at the footage to her right as the dark figure follows the directions towards the office of Yulian Filippov, a gang member of the Russian mob within Gotham City. His crimes consist of murder, human and arms trafficking and likely involvement in illegal drug trade with the smaller yet ruthless Irish mob. This piece of filth unfortunately has friends in high places, disposing of any evidence of his existence.

But they can't disappear completely, they never do. There is always some form of trace that leads back to the culprit.

Fingers tap impatiently against the arm of the sleek black chair, the dark figure in the security footage unlocks the door. He is fast, so fast that sometimes it's hard to see how many of those thugs he has been fighting. She has been watching him for a good 6 minutes, the back entrance of the building currently has two guards asleep or that's what they are presumed to be. The Russian must be quite cocky if he thinks no one knows what he's done or that this woman is about to have access to his computer which will unlock all his secrets.

The rootkit will be entered onto Filippov's computer and her software programme will upload without alarming any security or protection. This gives access to take what's needed without a trace.

"I'm in" fingers move automatically, sometimes she doesn't even notice. "I've done it. I have the files" they're encrypted but that's easy to fix.

34% decryption complete.

There is movement to her left, the security footage from camera 004 shows two, no five guards entering the building.

56% decryption complete. They're approaching the staircase.

"Five Guards have entered the building, heading your way" Thea tells him, trying to keep herself together. The bravery she wears is a mask, he is the brave one – always had been.

He's gone, must be hiding in the corner or something. She can only do her best with the quality of the footage.

73% decryption complete. Nearly there but it feels like it's been hours. The unbearable intensity of what may happen next.

Their shooting everything hoping to have caught the large black figure. But they're not smart, they're dumb. They don't know what they are dealing with.

82% decryption complete and two guards down. It's a game of cat and mouse; It can be amusing to watch but that's not how she really feels.

Her hazel eyes follow the guns held by the three guards and know that when they shoot, he could get hurt or killed. That's not the case with the suit he is wearing but it's just one of those feelings. She doesn't want to lose him.

100% complete and five guards down. The files are saved and it's done. "I have them, get out of there" her voice calls out in an urgent tone.

She lets out a deep breath. "You're not the only one that worries Thea" A voice behind her speaks, Alfred has been working on some upgrades for the weaponry.

"I know, I wish I didn't have to" She has lost count of how many times they've said that, the need to scream at him and say 'why do you do this to yourself?', 'why do you put us through this?' Althea and Alfred don't deserve it, they're here as family not a couple of strangers to cry over a dead body.

It's a grim way to look at this life, but Thea accepted it a long time ago since delving into the criminality of Gotham City.

She slowly stand up and stretch, grabs her jacket whilst walking towards Alfred. "I'm gonna head off, I've done my work" Thea sighs and glances at her watch, 2:00am.

Even though both individuals are against his nightly endeavours throughout Gotham City; The exhaustion of worry, knowing that a bullet or knife is out there ready to endanger the man even more. However, this life doesn't consume hers; Thea lives in the 'nice' part of Gotham City attempting to ignore her past misdeeds.

Alfred is about to speak when the roar of engines enter the cave startling the both of them. Bruce Wayne making a grand entrance whilst leaping out of the vehicle and withdrawing his cowl. The man is physically exhausted by the drooping nature of his shoulders as he drops down into his chair; His eyes, Thea always notices them first, they don't convey happiness anymore. That façade is only placed when posing in front of a camera.

"You're late, Master Wayne" Alfred speaks up, brushing his hands on his apron and goes to make a drink for the older Wayne. "I've been busy" He sighs, this life he is leading, the vigilante one, is going to be the death of him.

He looks up at the young woman, "Thank you" he tells her, the gratitude is apparent with a slight tone of guilt. This is never what he wanted, his little sister should of stayed completely away from her past activities, protecting her as an older brother should. "I know, but I do have a meeting at 7:00am regarding a very generous donation." She responds with a slight smile on her face, the involvement within the Martha Wayne Foundation gives her something to live for. The orphanages, children and those deprived from medical care and education, she couldn't leave them.

"Did you find what you needed?" Alfred asks while walking towards the older Wayne with a tray of food and drink, Thea left the cave six minutes ago. They make sure she has left before delving into details of the vigilante's recent activities.

"No. He was useless, Thea's help will secure him a place in prison but there was nothing to lead me to the man I need." Bruce sighed looking through the files obtained by his sister, her skills surprise him every time; her knowledge of computers is a slight step up from his own intellect, though he would never admit that. "And who are you looking for?" Alfred sets down the tray and look at the screen as Bruce opens a file "Anatoly Knyazev, contractor all over the globe but he is based in Gotham."

He opens several security images of the man in question, the black combed hair and hand tattoos paired with menacing eyes. "So this is the white Portuguese? The one you're looking for?" Alfred questions him whilst looking at the images displayed. "No. This is the man who knows everything, the one who will lead me to the man himself" Bruce answers in a gruff tone, Alfred prepares him some coffee.

"You don't even know if this white Portuguese exists, he may just be a phantasm." Alfred pours the hot drink and passes it to Bruce "one that wants to bring a dirty bomb into Gotham." He takes a sip of his drink whilst becoming lost in the decrypted files. Alfred returns to the tray, "I stand corrected." Bruce subtly nods but hears the older man murmuring, "You can't lie to her now."

The elder Wayne looks towards him questioningly; Alfred notices and drops the Gotham Press newspaper on his desk. 'BAT BRAND OF JUSTICE' the title reads with images of a criminal discovered by the vigilante earlier in the week.

"After all these years it seems that justice becomes more brutal. I know you hide things from your sister, but soon enough she will have to read about your death in the papers." Alfred speaks up with a slight anger and annoyance in his tone. He walks back to his work bench ignoring the stares from Bruce. "I never should have involved her, I know that. But when she discovered who I was and knew what I was dealing with, she offered to help. Now that son of a bitch is in Arkham, rotting away and paying for what he did to Jason – to us. Without her I would've broken my rule and crossed the line, and I've told you Alfred, once I cross that line I can never come back." Bruce's voice becomes louder, the past breaking through. Taking a deep breath, he slouches in his seat.

"I was just as surprised as you were when she confessed of her illegal activities, and horrified by the incident that stopped her from ever doing that again. Master Wayne, our young Thea is now scarred forever because of the circumstances that have occurred in the past." Alfred looks at the vigilante, who now appears with a grim, disgusted look.

Alfred continues "But now is the time to move on, don't keep reeling her in to help – she is brilliant at what she does and I don't deny it; I can see it in her eyes, her scars cut deeper whenever she opens a criminal's file about how they murdered their family or molested children. Don't let your nightly activities ignore the only family you have left, Master Wayne." Alfred finishes and returns to inspect the weaponry.

Bruce presses a button on his keyboard to lock the screens, all fading to black. To protect the citizens of Gotham, that's what he promised himself. He couldn't even do that right; those close to him either die or get hurt. He's learned that lesson, the loss of Jason and the near loss of his sister. Thea is his anchor, the one that stops him and keeps him in check, if he lost her then there would be no stopping the dark knight to rage war upon his city.

Althea was only nine months old at home in the Wayne Manor with Alfred. Her mother hadn't left the house in so long because she never wanted to leave her second child, but her father persuaded her to go watch Zorro in the theatre and have a break from the worry and enjoy herself. That's when they died.

The younger Wayne grew up not knowing her parents and Bruce has to live with watching them die in cold blood. Bruce and Althea Wayne, those poor children. Throughout their childhood that's what they would hear. But they weren't alone, Alfred is a father to Thea as she's never known another. Bruce is her saviour, without him she wouldn't have known her parents or their family at all. She would learn from her older brother of Thomas and Martha Wayne; how they met, when they where married and the stories of Bruce's childhood with them. All Thea and Bruce can do is uphold their legacy, he is the CEO of Wayne Enterprises and she is the leading supervisor of The Martha Wayne Foundation. They can continue what their parents started and make Gotham a better place.

That was what she decided to do when stepping out into the world and really begun her life. Though the younger Wayne has found a particular interest into something illegal as previously mentioned.

Hacking. Bruce vigorously pointed that out its illegal nature to his sibling alongside the danger of being caught. She has helped a few people discover some things including the GCPD, 'assisting' their case regarding child slavery and saved lives. However, it's not a part of her anymore, after a very close call – now having a scar to show for it.

Her skills are only acquired to assist Bruce when he needs it, this brings an almost hatred to Thea but mostly because her worrisome nature. It's been several years since she began assisting Bruce's endeavours and if she stops now, the feeling that one day Thea will let him down when he needs her the most haunts her. That's what family is for, right?
