Chapter 1
Lilith Luthor found out she wasn't supposed to exist on the worst and best night of her life.
Her mother, Lillian Luthor, had called her down to the basement in their new house. For whatever reason, Lillian made them move multiple times a year, but Lilith thought that was just the scientist in her mother; she wasn't able to stay still.
Their new home was in the suburbs of National City. It was old and large, but it had bay windows that Lilith sat by, staring out and working on her drawings. One time, she saw Supergirl fly above the window. She looked like being able to fly was the best experience of her life. Lilith now often sat by the windows and contemplated what it would be like to have Supergirl's abilities.
In every new house they had, the basement was always the lab. Lilith didn't always know what her mother was working on, but Lillian occasionally showed her a project if she thought it was interesting enough to warrant attention.
"Lilith! Come here and look at this chemical equation!" Lillian called.
"Coming!" yelled Lilith, muttering under her breath about how she was never going to be able to finish her sketch at this rate as she began to trudge down the rickety stairs into the old room. When she reached the cold cement floor, she knew her bare feet should have felt the chill, but such things never seemed to bother her.
She walked into the main room of the large floor and saw Lillian wearing goggles among many beakers filled with various colored liquids. She was stirring a purple substance into a red liquid, which was oddly making a strange, glowing, green material.
Lillian beckoned her over, and Lilith had to be careful not to trip over any of the cracks in the old floor. She made her way over. As she as she got close to the green material, Lilith felt ... off. Something wasn't right. She never got sick, yet she had a headache and felt debilatated.
Lilith winced, and unfortunately, Lillian noticed, pulling away from her lab table and taking off her goggles as Lilith gripped the table to avoid falling.
"Lilith? Are you okay? How do you feel?" Lillian asked in a quick progression. Lilith thought she had a slightly malicious gleam in her eye, something too curious in her gaze, but she couldn't make it out completely.
"Feel ... sick ... help..." And with that, Lilith Luthor passed out.
When she woke up, she was laying in an uncomfortable bed. She heard voices she had never heard before bickering over her.
"-needles can't pierce her skin; she was hurt by the kryptonite'"
"she looks exactly like Lena-"
"if she is kryptonian, why was she with Lillian?"
Lilith sat up, gasping in air as fast as her lungs would allow her. The three voices abruptly stopped, but the brief silence was taken over by the rapid beeping of machines.
She looked all around. She was in a room with walls of glass, and there were many cabinets and medical tools around her. She was under red lamps. The buildong she was in looked like an open floor office building, with a logo on the floor. There was a balcony on the level beneath her room, heavily protected by metal and more glass. There were numerous hallways leading further into the depths of the building.
Lilith continued to breathe heavily as three people, presumable those who had been arguing moved closer to her. One of them was dirty blonde who was wearing glasses and pastel colors and smiled at her. There was a brunette woman who seemed ready to beat Lilith up. and held the dirt blonde back, as if protecting her from Lilith. The third, a tall black man in a black polo, merely regarded Lilith calmly, and she couldn't read his expression.
"What happened? Where am I? Where's Lillian? What time is it?" Lilith asked in rapid fire. "And, gosh, I'm really hungry, do you have anything to eat?" Now all three stared openly at Lilith in shock.
"She sounds just like you, Kara," said the brunette to the blonde, almost laughing even as she kept her body protectively in between the two.
"Hello, and welcome to the DEO, the Department of Extranormal Operations. My name is J'onn J'onzz; I'm the director of this facility. You're here because you count as 'extranormal.' You've been here unconscious for four hours; it's about midnight."
Lilith's mind reeled at this information. Surely this was just a government screw-up, and they would let her go home soon. There was no way she was what these people were looking for.
"Hi, I'm Kara Danvers," said the blonde. "Alex, get the poor girl some food."
"Hi, I'm Lilith Luthor," replied Lilith, calmed by Kara's friendliness. The way all three of them cringed at her last name was not lost on her, but Alex, the brunette, huffed and walked to a near-by cabinet to the bed's left and grabbed a pack of granola bars. She tossed two to Kara, then stalked back over by J'onn, abandoning her protective stance over Kara.
Kara smiled at Lilith again, then handed her the granola bars. She took them gratefully, opened them, took a bite, and moaned with pleasure. They were the best granola bars ever. Somehow only one bite had given her lots of energy.
"So ... why am I here? I mean, don't get me wrong, thanks for presumably helping me when I passed out, but where's Lillian? Also, what is this? It's really good," Lilith asked after she had inhaled the first bar.
The three adults exchanged glances. None of them seemed willing to explain. Eventually J'onn elected to speak.
"Lilith, you live near National City. You know Supergirl, right?" he asked as Lilith opened her second granola bar.
Lilith nodded. "Of course I know who Supergirl is. Lillian's, like, obsessed with her," she said. Again, the shared cringe occured.
"Here's the thing: Lillian is the leader of Cadmus, an anti-alien group who has tried to hurt Supergirl before. Right now, she's in interrogation. You are here because, much like Supergirl, you also appeared to be weakened by kryptonite, a green substance, and your skin can't be broken. We aren't sure exactly who you are or why you're involved yet, but rest assured, we'll find out," finished J'onn.
Lilith tilted her head as she tried to absorb this new information."So... you're saying that I'm like Supergirl... and my mother wants to kill Supergirl, and possibly me too?" she asked.
Alex shrugged. "We're stil trying to figure out exactly what's going on. In the meantime, are you still hungry? Usually K- Supergirl needs to eat at least 500 calories per hour, and you seem to be 2,000 behind."
Lilith easily caught Alex's stutter. "Yes, please. I am really hungry. Also, you could have just said Kara is Supergirl. It's not that hard to tell," she replied, and all three adults laughed at her reply, although Alex still seemed tense.
Alex and J'onn left the room, but Kara stayed behind. "Is there anything I can do for you?" asked Lilith.
"Well, do you know Lena Luthor?" questioned Kara.
"Of course! I love her work. Lillian always told me we weren't related in any way, despite the last name," answered Lilith.
"Lilith, Lillian is Lena's adoptive mother, and you looks nearly identical," said Kara with a crinkle on her forehead. She looked confused, as though this were all a puzzle that didn't have any matching pieces.
Lilith was about to say she didn't know anything when Alex and J'onn re-entered the room through the glass door.
" We checked on Lillian in the interrogation room, and she is saying that she'll only talk to Lilith and Supergirl together," Alex couldn't look Lilith or Kara in the eyes, but a similar crinkle had formed on her forehead.
Kara shrugged, then a burst of air made all the machines start beeping again, and all of a sudden she was in her Supergirl outfit.
Of course she can do that. Superspeed, thought Lilith.
Alex walked forward and pressed a button, and all the machines stooped their incessant noise.
"Kara can take you down to the interrogation room while we get you some food," Hank said, his face a mask.
Lilith nodded, and swung her legs over the side of the bed. As she stood up, she realized that she was wearing red, yellow, and blue pajamas with the crest of the House of El on then. She smiled at what was obviously Kara's fashion choice. She allowed Kara to lead her out of the med bay, feeling the stares of Alex and Hank all the way down a hallway.
Kara and Lilith passed many more people waering black uniforms, but none paid them any attention. They walked for what felt like forever down a brightly lit hallway, then Kara finally stopped at a door. She paused, with one hand on the handle.
"Ready?" she said.
"As I'll ever be," answered Lilith, and Kara swung the door open.
They both walked into the room, and Lilitg immediately noticed one way glass, black walls, and cameras. Then she noticed her mother, hand cuffed to a table in the center of the dark room.
"Lilith! Are you okay? What have they done to you?" Lillian cried as she saw her daughter walk in after Supergirl. She attempted to reach Lilith, but the cuff prevented her from doing so. Her eyes darkened when she saw Kara and Lilith holding hands.
"She's fine, Lillian, but you have some explaining to do," interrupted Kara. Both Lilith and Kara remained standing, although Lillian was seated in a metal chair. Lilith wasn't sure about the whole situation, but she had no reason to distrust the DEO unless her mother gave her one.
Lillian bowed her head and sighed. "Very well. I suppose I owe it to Lilith, although not to you," she responded venomously, glaring at Kara. "The only reason you're here is to help Lilith."
"Well, I suppose it doesn't matter why I'm here. Start talking," ordered Kara.
Lillian sighed once more, rubbing her forehead with one hand. "Lilith, you are not actually related to me in any way. I created you, though. You are made up of Supergirl's and Lena Luthor's, my adoptive daughter's, DNA. I made you to have all of Supergirl's powers, but stronger, and all of Lena's genius. You have Supergirl's eyes and personality, so that people would trust you, but you look very similar to Lena so that no one would question you being with me," Lillian began. Lilith felt her world fade away as her not-mother broke her understanding of how her world worked.
"You look as though you are fourteen, but I actually made you a year ago and gave you false memories," Lillian revealed. "You were affected by the kryptonite because I knew you would achieve all of your kryptonian powers when introduced to your weakness."
Lilith and Kara were stunned. Of all the possible explanations, this was not expected.
Kara turned to Lilith with concern in her eyes. "Lilith, we can talk about kind of being mother and daughter later, but for now are you okay to continue this conversation? Or do you want to take a break?" she asked. Lilith nodded, although she felt almost as weak as she did when she was exposed to kryptonite.
"Why? Why pretend I'm your daughter? Why do I exist?" Lilith asked past the lump in her throat.
"Lilith, the kryptonians are dangerous, and Lena has fallen under their spell. I kept you with me in the hope to turn you against your mothers. I wanted to train your powers," Lillian continued. "Lilith, please understand. Even if you aren't technically related to me, I still feel like your mother. I never wanted to hurt you, believe me."
"Why should I believe you? Everything you told me is a lie. I shouldn't be alive, and I never want to see you again," shot back Lilith, and she reached blindly behind her back for the door handle. She felt it, then opened it and stalked out of the room. Kara silently followed her, staring at Lillian wordlessly until she closed the doo, leaving Lillian alone with her head in her hands.
Lilith couldn't begin to describe how she felt. All of the frustration, anger, and confusion she felt was blinding, and she lashed out. She punched a wall, forgetting her new strength, and made a crater in the smooth rock.
She trembled, the hole only cementing Lillian's story. Tears started streaming down her cheeks, and she felt Kara holding her from behind. Lilith gripped Kara' forearms as tight as she could.
Soon, Alex and J'onn came running down the hallway; the impact from Lilith's anger must have attracted their attention. They stopped in their tracks as they sae the two people in the hallway. All three adults stood in silence for as long as Lilith needed to process the information, even though Alex and J'onn didn't know why.
They were there for quite a while.
