AN: this is my first fic, I'm usually just an avid reader. I have no beta, so mistakes are all my own.
Obviously I don't own Supergirl, or any other DC characters
This idea has been rattling around my head for a few days, and had to get it out somewhere, I hope you guys like it.
She had secrets. To get where she was in life, she had to have secrets. No matter how much she hated it.
Most were innocuous little idiosyncrasies more than anything. Like how when she was down, she would happily devour six Big Macs without a care in the world, but would feel like the world's biggest asshole after the fact. Or how scratching the back of her head would almost immediately put her to sleep. Small things, mundane things.
Of her biggest secrets, the main one was currently staring back at her from her bathroom mirror; hair tousled from sleep, eyes bagged from what was essentially a three hour nap, more than real rest, green irises slightly dull from the ridiculous amount of overtime she'd recently indulged in. She chuckled to herself as the idea of her being her own biggest secret wafted slowly through her mind.
It was her mother's fault. Not Lillian, she was just a thorn in her side. Her biological mother; Elena Ohn-Ne. It was her sweet, caring, loving biological mother's fault that she was keeping a huge secret; and while she didn't blame her dear mother, it was beginning to grate on her nerves.
I miss her tremendously, though
It was true. Her real mother had been the light of her life. Now that light was marred by the memory of glowing green ooze that had spilled from the wound in her chest, as her body hit the floor in front of the bed Lena had been hiding under at the time. She shuddered at the thought. The few that knew about The CEO's past, had been told that Elena had died in a house fire, that Lena herself had narrowly escaped. That was a blatant lie. Lena's mother had been murdered, and would gladly tell that the anyone who asked. Not that anyone did. She was a Luthor now, regardless of her past. Regardless of what her name had once been.
She was thankful that no one asked, if she was honest. Even the dear, sweet Kara Danvers/Zor-El/Supergirl (because of course she knows, Kara is her best friend, and Lena is a genius) had not pried about Lena's real mother, although Lena knew that was because Kara didn't want to bring up upsetting memories for her best friend, not because she didn't care. Unlike everyone else. But it was easier this way, she approached it like a "don't ask, don't tell" arrangement. It was far easier to hide if no one asked in the first place.
She drifted casually towards the shower, dropping her almost see through camisole to the floor as she went, toes grazing over the garment as she floated over it to get into the cubicle. She often wondered if Supergirl was as sluggish as she was at this time of the morning. Granted, she was only half-Kryptonian, but still; maybe it was a species-wide phenomena?
And that was her biggest secret. Half Kryptonian, half human, as well as the first and only of her kind; at least to her knowledge. Because apparently she wasn't lonely enough. A wry smile graced her features as she continued to lather shampoo through her hair. Having grown up with her abilities, she had exquisite control over them, probably more so than Supergirl herself, so that wasn't hard to hide. Her human DNA meant that she was impervious to Kryptonite, so even if she were exposed to the substance, no one would be able to guess that she was Kryptonian. And up until recently, she'd had no intentions of becoming some heroic figure the people would look up to, so she would only ever really be noticed for her contributions to society as a Luthor.
But things were changing. CADMUS was beginning to stir, and this new 'Reign' woman was somewhat of a concern, almost as much so as CADMUS. And that was making her think very hard about her current lifestyle. She stepped out of her shower and into the bedroom, glancing to the left side of her bed as she moved through the room. Her little cache of Kryptonian technology, along with her mother's old armour, sat behind the wall to the left of Lena's bed. After a moment of contemplation, Lena moved towards the hidden doorway, sliding the crystal swan on her bedside table to the left, thus releasing the deadman-switch style button that kept the door closed. The door slid open silently, and she stepped into the room, absentmindedly rubbing her hair with her towel as she surveyed the room.
From left to right there were pieces of scattered technology, things she'd pulled apart to investigate, notes scribbled on various bits of paper and all manner of random bits and pieces, strewn haphazardly about the room. The only thing in there that had never been dissected, was her mother's armour; hanging proudly in the centre of the back wall; silver cuirass, vambraces and pauldrons gleaming in the artificial light, greaves sheathed in shadow, but still just as polished, a deep purple cape hung from the right shoulder, and a helm with partial face covering sat atop the mannequin. Lena smiled, remembering the stories her mother used to tell of her time as the Captain of the Guard of House El. Her favourites had always been of little Kara Zor-El. Seems she was just as sunny on Krypton as she was on Earth, and that drew Lena in, even as a happy child.
Her nostalgic smile faltered as she remembered what was going on with CADMUS, and the recent addition of Reign. It was almost like they had been tag-teaming. CADMUS would launch an attack, and within 24 hours of that being dealt with, Reign was up to something. Kara had looked utterly exhausted at lunch yesterday, which is what had caused Lena to wonder if it might be time another super joined the fray. Moving and destroying Kryptonite just wasn't cutting it anymore. She shuffled the thought to the back of her mind, she would think about it later. She had to check on her second biggest secret, after all.
