I do not own Supergirl. All I own is Christi and those you do not recognise.
This is a plot that I couldn't get out of my head and it wouldn't stop bothering me so here it is. If there are any spelling errors or such do PM me.
Christi Emerson. That was the name she took when she had landed on Earth, over twenty-four years ago, to the day. When she had arrived, oh so long ago, Christi was surprised no one had noticed, nor came for her. See, she had been observing the planet and it's tendencies to capture aliens. When no one came, she played it off as dumb luck and carried on, waiting. Christi had a history with Kara Zor-El and her family. She used to visit Kara's mother, Alura, and often found Kara studying different planets and species. One time Kara had come up to her asking about her planet and species, knowing full well that Christi wasn't a Kryptonian. Christi's race had died out long ago, drawn into a massive war that destroyed everyone and everything she had ever known. Her planet was gone, name forgotten except in some of the eldest books held within few planets. Christi was an Elrizan, from the planet Elrizia.
Elrizia was one of the most powerful world's alongside Krypton. A land with silver trees and red grass that seemed to catch fire when the sun and moon crossed paths. Unlike other planets, when the moon and sun crossed it didn't become an eclipse, the moon became transparent. Yet it dulled the sun enough for the sky to become night, but with a shining light among the stars. The silver trees lit the stars of the night and seemed to shower sparks of light onto the fiery ground and into the sky. And the world itself looked to grow transparent, and disappear. It was always an amazing event when this happened. Many people from neighboring planets came to see the splendor of the Elrizan home world on such a wondrous night.
Despite their powerful reputation, the people of Elrizia were one of the most peaceful people out there. The wisdom of their long lives, and noble nature helped them solve many disputes without the galaxy. But then a group rose up from within Elrizia, wanting command, control, and overall domination everywhere. A war began and soon friends fought friends, families turned on one another, and nowhere was safe.
For a long time the war raged on, and Christi never knew about it having been on Krypton the entire time. (Few Elrizans had ever left their home planet because they preferred the quiet life. Obviously, Christi was one of those who left, as she loved the stars and wanted to travel.) No one on Elrizia was able to send a message for help and as a result, the planet destroyed itself. Billions of lives lost, an entire race destroyed. All Elrizans gone. All but one, at least. Christi had only found out when she tried to go home. Alura's ancestors had been the one to break the news to her, having been one of the few people who knew Christi the best. The last being Kara and Alura.
Kara had been so interested in Christi's planet and she wanted to ask more about it but Christi had to leave, and she wouldn't be back for a long time. During that time the Kryptonian home world became unstable. Months went by and Christi knew this world would die just as hers had. So she went back to Krypton - the same day Kara's mother had summoned her, an urgent request. Alura had instructed her to look after Kara mere days before the planet had gone up in flames. Alura had met with Jor-El and they had to decide the destination that Kara and Kal-El would use. Once decided Christi left immediately to Earth, a strange planet she had studied, and waited for Kal-El and Kara Zor-El to join her. When only Kal-El had shown she had grown worried. Kara was supposed to be right behind him.
Christi waited, and waited, and waited. Despite all of the time it took for Kara to get to Earth, Christi spent her time watching over Kal-El, now known as Clark Kent, and to the world, as Superman, or the Man of Steel. For years she moved around to not draw any attention to herself because she aged so slowly in Earth's atmosphere. Even slower than a Kryptonian, her DNA having already granted her a long life - like the rest of her species. She kept an eye on Hank Henshaw whenever he came around. The Department of Extranormal Operations, or DEO, didn't need to be in her business. She had accidentally found out about them when she had studied Earth.
Finally, after many years, Kara Zor-El had arrived and was still thirteen years old. Christi had no idea why, her guess being the Phantom Zone, or a wormhole displacement, but she was glad Kara got to Earth safely. And Kara grew up never knowing she had a guardian watching over her or her new family. Christi knew she was in good hands and stayed close by.
Twelve years after Kara arrived, Christi lived in National City and worked at CatCo Worldwide Media, keeping her word and looking after Kara. If she hadn't taken the job it would have been weird for her to hang around when she didn't even work there. Christi worked a few desks over from Kara but could see her perfectly. Christi became friends with Kara only a week after she joined, which was a few months after Supergirl had shown up. Being friends with Kara also lead her to be friends with Winn, and later on James Olsen. It wasn't so bad working at CatCo. As long as you weren't the one being called to Ms. Grants office.
On a normal day Christi would rarely answer calls, write emails, and overhear Kara talking to Winn about some crises she needed to deal with. But on other days, if you were lucky enough, you could see Supergirl fly around the city. Never once had Christi ever used her abilities, as she never needed to. But she kept training herself in case she was ever needed. The humans had two heroes now. Why would they need a third? That's where this story begins.
Kara never told Christi she was Supergirl, mostly because she hadn't been around that long. And although Christi was fine with that, something strange had been going on with Kara. Ever since that fire, she had been acting weird. Christi only brushed it off but it gave her some concern. Yesterday Kara walked in wearing something Christi knew she would never wear, last night she saw Supergirl let a criminal go. And just this morning Kara used Cat Grant's private elevator. Dear lord if Cat Grant new. . .
Even now as she typed away at her desk she glanced up at Kara, who was nearing Cat's new assistant's desk. The alien criminal from last night worried her but she just shrugged it off. Maybe they got the wrong person and that guy was a refugee of some sort. But just the way Supergirl acted really put her on edge. Something was wrong and when Kara sat down at that desk, Christi knew her suspicions were correct.
A ring at her desk made her jump a little and she answered the phone. Just another person who thought they found something CatCo would publish. Her thoughts strayed as she wrote down what this person said. As she finished writing and hung up the phone, she heard Cat talking to her assistant, Siobhan. By how she didn't need her super hearing to hear them. She knew Cat was talking so people could hear her.
"You are, fired!" Cat Grant spoke, putting emphasis on the 'd' in 'fired' and getting louder as she spoke. Everyone turned to look at what was going on within the office. It got quiet and people could hear Cat. Not that they needed to strain their ears to do so anyway. "Now before you go skipping all the way back to Metropolis I will save you the bus fare," Cat spoke. "I had a much too long conversation with Perry White and there is no job waiting for you there." Cat hummed. "Now, be gone."
Cat waved her hand in a dismissive gesture and went back to her business, not even giving the girl a glance as she left. James and Christi walked up next to Winn as she passed the three.
"Hey, are you okay?" Winn asked, concern evident in his voice.
Siobhan ignored him and continued on her way out, glaring at everyone who stared.
"Well I guess that's your exit," Kara spoke.
That did stop her in her tracks. She turned and looked at Kara before stalking off. Everyone went back to their business. It was often that Cat fired someone, but not so often there would be no reason to watch.
Kara clicked her tongue, "Well, that was awkward. But not surprising though." Kara went over to her desk, Christi's eyes following her all the way. "She was a bad seed, it was only a matter of time. I know what will lighten the mood, drinks, and dancing. Who's in?" Kara held up four passes to a local club.
Why she had those Christi would never have guessed, but she went with it anyway. If Kara could get drunk, maybe she can get answers as to why she was acting so strange. She doubted it though. These drinks were weak compared to her immune system and she could only assume the same for Kara. That night they all headed to the club. Christi wearing a white sleeveless top and a black skirt going just past her knees. Her dark hair up in a ponytail and her blue eyes searched around the club for her friends, finding them instantly. James wore his blue sweater and jeans while Winn wore a dark blue button-up shirt and jeans. Kara still hadn't arrived.
"Today's music is so loud! Right?" Winn hollered over the music. James laughed at him. Christi only had to glare at the roof. For her super hearing, no matter how much she dulled it, the music was still too loud. "Siobhan still has not texted me back. I hope she's okay."
"She's fine," James answered.
"Yeah just give her some time," Christi agreed, glancing down at Winn after straying her eyes from the roof.
"Speaking of which, Kara said she was going to be here soon." James checked his phone. "Do you think she's still on her way?"
Christi and Winn both downed their drinks.
"Oh yeah," Winn said.
"Oh hey, there she is!" Christi called, pointing past James.
"Yeah I see her, I think. . ." Winn trailed off suddenly unsure. Christi chuckled at him. "I think that's her."
Kara was wearing a black dress with heels. Her hair was down for once and she took stride in her steps. As if where she was going was very important. Christi was still worried. Kara would never dress like that. But the dress could've been something very different.
"Hey! Wow," Winn said looking Kara over, impressed slightly by her choice in style.
"Hey, Cat, look at you," Christi teased, throwing her a wink.
"Wow," Winn said again.
Kara smiled at them and looked at James who also took a minute to look at her. "Yeah, that's what I was going for. You want to dance?"
James looked slightly taken aback by the question.
"Uh, yeah. Yeah. Oh!"
James jumped at how Kara grabbed his arm and walked with him towards the dance floor.
"Like the girl's got a grip of steel." Christi watched the two walk away.
"You have no idea," Winn snorted.
Christi looked at him curiously. He didn't even seem to notice he slipped up. But with Kara on the dance floor she might have a chance to question Winn. So she simply waved at the bar tender and pointed at hers and Winn's drinks.
"Hey Winn?" Christi started.
"Yeah?"
"Where did Kara get the tickets for this place?"
"Oh I gave them to her for her birthday last year. I forgot her birthday and it was the only thing I had with me so I improvised."
Christi nodded and downed her fifth drink, silently questioning why Winn had four tickets to a club. Winn followed suit and drank his. As soon as Winn finished, Christi brought up her question.
"What did you mean when you said, 'You have no idea'?" She asked.
"What?" Winn hollered as the music got louder.
"Earlier. I commented about Kara's 'steel grip' and you replied with 'You have no idea'. What did you mean?" Christi asked, giving her best confused face.
True, she did want at least one person to admit that Kara was Supergirl, but it wasn't her best idea to do it in front of so many people. Of course, no one would pay attention to them but there still are others out there with prying ears. Winn seemed to pale slightly.
"Oh well, uh. Kara just has a death grip since she tends to carry a lot. Not-not that Kara, uh, carries around a lot she's probably just strong," Winn stuttered.
Christi only nodded and looked over at where Kara and James were. James was walking back over with his phone in hand. Winn looked over as well, glad that Christi's focus was on something else.
"Oh, why don't you just tell her to get back in her litter box and leave us alone?" Kara whined.
James only scoffed and answered his phone, "Ms. Grant?"
"I need to talk to Supergirl," Ms. Grant said.
Christi's hearing could only barely hear the other end of the conversation, it being so dulled. Winn had gone to the restroom only seconds prior. Mumbling something about 'shouldn't have drunk that last one'.
"Press your silly watch or whatever it is and send her here now."
James shook his head in bewilderment and closed his phone.
"Ms. Grant wants to see. . ." he trailed off seeing as he was the only one listening. His gaze shifted to Winn who had come back. ". . . Supergirl. Where'd Kara and Christi go?"
"What happened?" Winn asked.
"Something's wrong with Kara."
"Yeah but where's Christi?"
"She's not with you?"
Three miles away a form flew after a woman in a red cape. It easily kept pace and its dark form keeping it unseen. Glowing green eyes watched as Supergirl landed on Cat Grant's balcony. The form slowed itself and landed on the roof of a building across from CatCo. Black boots silently ran across the roof as it neared the edge, only a few stories above the balcony. It lifted its form onto the edge and sat on its haunches, hearing being strained to listen in on the conversation.
"What do you want?" Supergirl asked.
"Well, I would like to know if Ashton Kutcher and his camera crew are hiding underneath your cape," Cat Grant said, walking into view. "Supergirl would never release an evil alien caught in the act of armed robbery. So, I assume I'm being, Punk'd."
"I wouldn't assume anything from now on, Cat," Supergirl argued back.
"Did you just call me, Cat?"
"You branded me in the media as a Girl Scout," Supergirl continued, ignoring Cat Grant, then mocking her. "'Supergirl is brave, kind and strong'."
"Mmm-hmm?"
"Isn't that kind of a stock characterization? Very two-dimensional. Everyone knows real people have a dark side."
The figure atop the building narrowed its eyes and stood. It was waiting for something. Supergirl would never act like this.
"Yes, but you don't get to be a real person," Cat fired back. "You're a superhero. You get to represent all the goodness in the world."
"Yeah, well I'm sick of it. And you know what else I'm sick of? Enabling all of you in your victim-hood." Supergirl turned around and set her hand on the railing, ignorant to the dark across the way. "'Oh, well, my building's burning down, la-di-dah. Supergirl will just swoop in and save the day'." Cat Grant crossed her arms watching the super hero. "Well get used to the flames, people, 'cause I quit." A small trail of red could be seen from the figures point of view. It was like red glowing veins going across Supergirl's face. It soon disappeared leaving a questioning stare from the figure.
"Supergirl. . ." Cat sighed. "I fear that you're having some sort of mental breakdown. Don't worry, it happens to the best of us, and I'm happy to take you to Dr. Shuman for emergency Lexapro, that is, if your alien brain will respond to the SSRIs. But in the meantime, I would lay low. This haughty attitude is highly unsuitable."
Supergirl turned on Cat, "Well, I learned it from the best. Cat Grant." Cat chuckled. "You are the most arrogant, self-serving, mean-spirited person I know."
This was escalating very badly. The figure wanted to stop it before it got too far but Cat began talking.
"Now, you listen to me," Cat Grant growled. "I made you. And you are not going to let me down."
"Or what?"
"'Or what?'" Cat repeated.
"Oh, wait. You're the most powerful person in National City. At least that's what they say on TV." Supergirl walked closer to the woman. "You want to see what powerful really looks like? Watch."
The figure watched in horror as Supergirl grabbed Cat and threw her over the balcony. Right as Cat Grant was over, the dark figure spread its arms and took flight. Diving off the building and chasing after the screaming woman. Diving underneath, Cat didn't notice the figure until she landed with an 'Oof!' atop something at a high speed.
The figure groaned but smoothed out its flight and landed, Cat Grant stumbling off the person that caught her. Cat breathed hard and looked at the figure that was now in the light. The figure, who could now be seen as a woman, was standing in front of her. Piercing green eyes, black as night clothes and hair almost white as snow itself. People surrounding them stood in shock, one pulling out a phone and taking a picture.
Supergirl suddenly landed next to them, only two meters away, drawing everyone's attention. "True power, Cat, is deciding who will live and who will die," she spoke. "And, don't ever call me again." Supergirl turned and flew off, leaving the street silent.
All stood shell-shocked at the happenings, all but one. Cat could swear she heard the woman snarl at the sight of Supergirl's retreating figure, reminding everyone of her presence. Cat Grant stood and looked at the black and white woman. She straightened and the two stared eye to eye. Everything was silent except for Cat's labored breathing from the shock of falling. The woman stared only a second longer, then took off. People watched as the figure blended into the night. This was a night to remember.
Also, if I don't finish this, please don't kill me.
