Hi everyone, I want to apologize for taking so long to update, I never meant to take so long but things just happened. I know a lot is going on in the world right now and I hope each of you is staying safe and healthy. Thanks to the person who requested this and I hope you all enjoy reading it.

Prompt: it was Alex who was attacked by the Black Mercy instead (maybe she jumped in front of Kara or was there when the plant was delivered to the apartment) and Kara has to go into her mind to save her.

This will pick up right after Kara goes into Alex's mind.

Kara looked around her, trying to figure out where exactly she was.

In a few seconds, she recognized the hallway she was in, this was in her sister's apartment building.

She began to walk down the hall to where she knew Alex would be, hoping no one saw her dressed in her Supergirl outfit. She wondered if they did how they would react.

It surprised Kara that this was where Alex lived, she figured her sister would be in some dream house or maybe even back at Midvale.

Finally, she came to her sister's apartment door, tentatively tried the handle, and was surprised to find it unlocked.

Inside the room was very similar to the real apartment. A few things were off though, just little things that Kara noticed were missing or additional things that didn't belong.

"Hello?" said a voice from one of the chairs. Kara had been so caught in studying the room that she hadn't even noticed someone sitting in the room.

Alex.

Kara didn't know what to say or what to begin with, did Alex even remember her? She had no idea what this world was like, so she decided to start with an introduction,

"Hi, my name is-"

"Hey Kara um.. what are you wearing?" Alex said over her, standing up and approaching her.

"Alex you know me? I mean I guess that makes sense but still that's kinda strange to think that I'm here too I mean…"

"What on earth are you talking about?" Alex said as she stood in front of her sister with a look Kara knew meant she was worried.

"I-look I don't know what you think this reality is, but it's not real. This world isn't real. You were attacked by something and it makes you hallucinate whatever it can to make you stay here, but this isn't real." Kara said.

She knew she must have sounded like a mad woman, but she didn't know what else to say and she just blurted it out, she should've prepared better beforehand.

"Haha very funny, where's your stuff? And what are you wearing? You look ridiculous." Alex asked as she moved to sit back down.

"Alex I'm being serious. Please I know this sounds crazy but-"

Suddenly both girls turned around at the sound of someone entering the room.

Kara had to do a double take, because standing in front of her was herself.

"What the heck?" all three women said at the same time, each taking several steps back.

"Ok, what is going on?" Alex said, voice raised as she stared at two copies of her sister.

"Who are you?" said dream-Kara.

Kara winced at the sound of her voice, did she really sound like that?

Dream-Kara was wearing normal clothes that Kara recognized. In her hand was a duffle bag.

"I'm you, I mean I'm the real you. You're not real." Kara said with a quiver in her voice.

This was so weird.

"Alex, who is she? What's going on?" Dream-Kara asked, moving over to Alex who stood protectively in front of her as Dream-Kara stood back.

Kara noticed the move, it was something Alex would do on instinct in the real world, but usually Kara wouldn't need it or want it.

After all, she was the Girl of Steel, she didn't back down to anyone.

But Dream-Kara was less assertive, and Kara wondered what that meant.

"I don't know, but in about two seconds I'm gonna call the police if you don't get out." Alex said, harshly staring Kara down.

"Alex please, just hear me out. Don't you at least want to know who I am? I won't hurt either of you I swear, just please let me explain."

Alex continued to glare at Kara, but Kara saw under the faked anger to the real emotion hidden beneath, Alex was afraid.

"I don't care what you have to say! Get out!" Alex yelled.

Kara didn't know what to say, how could she get Alex to even start to listen?

Maybe if she could mention something Alex trusted, something that would lead to Alex wanting to listen.

"I work with the DEO." Kara blurted out, hoping against all hope that Alex would become interested.

"I don't have a clue what that is and frankly I don't care. Now I'm gonna tell you one more time. Get. Out." Alex said, her voice low as she still stood in front of Dream-Kara, arms crossed in front.

"You work for them, Alex please you work for the DEO remember, with J'onn and Winn and James? And me. You and I work together, please I know this must ring a bell. Come on Alex, think!" Kara said.

"No, I don't know what you're talking about, I don't work for any DEO, I'm a doctor, and you're on your way out." Alex said as she stepped forward.

Kara didn't want to get into a physical fight, so she backed up.

"Please Alex, try to remember. You have a life, a real one. And it isn't perfect, you lost your dad, you had hardships, life isn't perfect but-"

I didn't lose anyone; I don't know what you're talking about." Alex said, but still a little hesitation was present in her voice.

Kara noticed, "You did Alex. But you've kept fighting and you've gained so much. Please try to remember, I'm Supergirl and you work for the DEO and we save the world together, remember?"

Alex moved closer still as her face became conflicted, as if she was thinking, starting to remember.

"The DEO…Supergirl…" She said quietly, looking away from Kara as she thought.

Dream-Kara jumped forward, "Alex, don't let her hurt me, make her leave."

Whatever sense of remembering that had been there was lost as Alex turned back to Kara.

"Leave now," She said stepping forward.

Kara continued to back up slowly, rambling as she did, desperately trying to get through to her sister.

"I know you hurt sometimes, but Alex those hardships make you who you are. You're a hero, you help save the world, together. We're a team Alex, you and me. Stronger together, El Mayarah."

Alex stopped walking, "El Mayarah" she repeated, looking away as some sort of comprehension seemed to pass behind her eyes.

"Yes, El Mayarah." Kara said in a sigh of relief at her sister's apparent remembering.

Suddenly the room shook, "Ka…Kara?" Alex said, clarity filling her brown eyes.

Dream-Kara ran forward and grabbed Alex, "No Alex it's not true, stay here, don't leave me." She said.

"I'm sorry, I cant, this… this isn't real." Alex said.

"No!" Dream-Kara said as the room violently began shaking, this time without stopping.

"Alex!" Kara called out as she stumbled forward, reaching for her sister.

"Kara!" Alex said as she reached for Kara, the real Kara, just as the world around them began to fade.

"I got you!' Kara said, blindly reaching for her sister's hand as the world around her went white and everything faded away.

Kara woke up back at the DEO, surrounded by everyone who was there when she first went into the dream world.

Immediately she looked over to where she knew her sister was.

Alex was still unconscious. Why wasn't she awake? She should be awake.

"J'onn!" Kara said, jumping up and standing uncomfortably close to him.

"What happened? She was waking up! Why did you pull me out?" she yelled, getting closer.

J'onn remained calm, he knew she wasn't really mad at him, she was only afraid.

"I didn't pull you out." He said

"Then what-"

"Look!" Winn said, pointing to Alex.

The black mercy on her was starting to recoil, finally dropping off and crawling away.

Everyone watched as Alex slowly woke up,

"It's ok, you're safe, you're ok." Winn said gently, but Alex made no response.

Instead she ignored every other person in the room and made eye contact with Kara, when she spoke her voice was low and laced with anger, "Who did this?"

It had been two days since the Black Mercy event.

Kara and Alex had yet to talk about it.

Kara knew they needed to. But Alex had been so distant, so unnatural around everyone, that Kara didn't think she was ready.

On that second day since the Black Mercy, Kara was at home, watching some mindless tv show and trying to distract herself from her concern for her sister.

Someone knocked, and Kara jumped up to get it, quickly x-raying it to see that it was Alex.

Surprised, she opened the door.

"Hey Alex, what's up?" she said as she let her sister in.

Alex walked over to the couch and sat down, Kara trailing behind her.

"Nothing, I uh just thought maybe you'd want to hang out or something?"

As Alex spoke, Kara sat down next to her on the couch, unable to keep a smile from creeping on her face at her sister's words.

Still she couldn't ignore that Alex was acting a little strange, her hands were about to rip a hole in the couch pillow she was holding, and her voice seemed stiff.

Kara knew Alex better than anyone, and she knew how they communicated to each other.

So she knew this was about the Black Mercy, knew that Alex was silently admitting she was ready to talk about it, and Kara was glad she was.

But Kara still had to handle it correctly, otherwise Alex would shut off.

"Yeah I would love to, you wanna watch this stupid show with me?" Kara said as she reached for the remote and hit play.

"Sure."

And for the next hour, neither sister said anything, just watched the end of that episode, and the next episode, and the next.

Finally, when Kara was beginning to wonder if she should try to start the conversation herself, Alex spoke.

"So that was weird wasn't it?" Alex said, her eyes still on the tv.

Kara knew what she was talking about and reached forward and paused the show.

"Yeah no kidding, especially seeing the other version of me, that was really weird."

Alex nodded.

"What was it like? I mean I was surprised that things were the way they were, so what all was different?" Kara questioned, hoping she wasn't pressing her sister if she wasn't ready yet.

Luckily Alex responded, "Well for starters, you weren't Supergirl, you were an alien and everything, but you didn't have any powers."

So that explains why dream-Kara was so tentative, Kara thought.

"And you said you were a doctor." Kara said, prompting more information.

"Yeah, I was. I didn't work for the DEO and Dad never worked with them either, so he was still…" her words faltered for a second before she took a deep breath and continued, "around." She finished.

Alex still looked at the blank screen, but Kara glanced over at her sister, noticing the wetness that filled her chestnut eyes.

"Alex I'm sorry that you had to go through all that." Kara said, reaching out her hand and placing it on her sister's shoulder.

Alex took a deep breath and put her hand on top of Kara's.

"It's not your fault, it's just really hard to have all that, to have everything perfect, and then have it just ripped away and come back to reality." Alex let out a little laugh to hide the sob that she was holding in.

Kara reached over and tugged Alex into her arms, holding her tight as Alex finally released the emotions she'd been holding back for the past few days in the form of deep sobs.

Kara cried a little too, because of the words Alex had said, "its not your fault"

But it was, Alex's whole dreamworld was perfect only because Kara wasn't Supergirl, she wasn't who she is.

Once again, Kara was reminded of all Alex had given up for her.

Was it worth it? Was she worth it?

Alex deserved better, Kara knew she did. But she couldn't change anything, so she just held her a little tighter as her sister slowed her sobs and leaned against her.

"Hey what's wrong?" Alex said, looking up at Kara to see tears in her eyes.

Kara shook her head in disbelief at how selfless her sister was, she was just crying her heart out, but she was more concerned about Kara.

"I just… all of this is because of me. I ruined everything for you." Kara said as it was her turn to avoid her sister's gaze and stare at the television.

"Kara." Alex's voice was strong, much different than the one she had been using a minute ago.

"Kara look at me."

Slowly Kara dragged her gaze to meet her sister's.

"You did not ruin anything, this is not your fault. Jerimiah is not your fault. If I didn't have you, yeah maybe I would've been a doctor, maybe I would've had more things, but I would not have been happier, not without you. You are the best thing that ever happened to me, without you I would be miserable."

"Yeah but-" Kara said, giving into her panicked thoughts and ignoring the voice of reason in her head.

"No. No buts, I love you, and you love me. and you are not to blame for anything. Even with the pain that we've had, I wouldn't change it, because we learned from it, and we grew closer together. El Mayarah."

Kara leaned forward and kissed her sister's head before resting it on her shoulder. "El Mayarah" she repeated, and they both knew it was true.

The Danvers sisters were at their best when they were together.

Thanks for reading and I hope you all have a great day/night!
