Day 7, 4 left. Eliza and Alex were starting to feel the consequences of their hard work. The fatigue was well present but their determination was what was keeping them awake. It had been two days since they had finally obtained a solid lead on how to eradicate the virus and it had been a huge relief, even though they knew they were far from their ultimate goal.

As usual, the two women had started their day at 7:30 in the morning. It was almost midnight.

"Come on, Alex. It's enough for today." Eliza said calmly to her daughter who was well attached to her microscope

"But Kara is getting worse" Alex contered without looking up

"Alex..." the older woman sighed. "You won't help her right if you are exhausted."

She had a point, and a good one. Alex sighed heavily, ready to give up, when she had a last minute idea.

"Wait! Just one more test." she begged looking at her mother.

Eliza didn't respond with words and just stared at her, annoyed. Alex smiled and did her one last test.

"Oh my god." the agent said in disbelief

"What? What is it?" Eliza asked suddenly exited and taking a step further

"Look! It's working!" Alex cheered looking at the petri dish

"That's-That's amazing! We did it!" she shouted taking her daughter in a joyful hug.

However, Eliza's smile didn't stay long as she realised the next step of the process.

"No. No, Alex. We can't celebrate now." she started watching Alex's smile disappear. "Remember, we have to test it on lab rats, we can't extand what happens in a petri dish to Kara's physiology." Eliza finished supporting Alex by placing her hands on her arms

"You're right. We can't." she said with a bit of defeat in her voice

"Come on. Let's sleep now."

The two women headed to Kara's room, like every night. Eventually an other bed had been added so they could both sleep correctly. Silently, Eliza and Alex walked in the room and had the same look on their face. They both stared at the woman in the middle for a few seconds, still uncounscious, still with high fever, still in danger. Like every other night, Eliza stood next to her adopted daughter's head and kissed her sweaty forehead before going to bed. And like every other night, Alex followed her mother, stood by her sister's side and took her hand, whispering some inaudible words to her lying form, probably updating Kara on her work, probably encouraging her, probably expressing her love to her. And then and only then, the two scientists would allow themselves to lay down and rest.

The next morning, Eliza and Alex woke up to the alarm on Alex's watch. Despite the unmesurable amout of pressure they were confronted to, the two woman could somehow sleep rather well. Maybe it was the fatigue, or maybe being in the same room than the other, in the same room than Kara, maybe that was the reason.

"Do you have the rats?" Eliza asked her daughter thirty minutes later

"Yeah, I got the authorization. An agent is supposed to bring them in a few minutes." Alex said walking back in her office

"Let's make sure we're ready then."

The two women started to clean the messy lab, throwing all of their unsuccesful attempts in one corner of the room just in case they would need to look at it again. Now they needed to get specific, to focuss their efforts on the one lead they had.

Alex and Eliza were replicating the anti-virus prototipe and putting it in syringes when someone knocked on the door. They both looked back impatiently and saw a men with a cage in the hands.

"Where do I put your pets?" he asked really wanting to get rid of his boring and uninteresting mission

"Over there please." Eliza said pointing at one of the tables.

The agent did as told and walked away under the intense glare of Alex.

"If I wasn't too busy on saving Kara's life, I would remind him the importance of his duty with an intense sparing session." the young agent said still glaring at the door

"I don't think you're the most qualified person to do that." Eliza smirked, laughing a little

"Excuse me? I'm his superior and I would totally kick his but." Alex contered getting back to work

"That's not what I mean. I'm just saying that at his place, you would grumble just like he did."

"Let's focuss, shall we?" the young woman proposed obviously annoyed

"Ready?" Alex asked to her mother an hour later.

They were just about to inject the first mouse.

"Do it."

Alex took a deep breath. She blocked the white mouse in her left hand and injected it with the right one. Then, Alex put the mouse down in her tiny cage.

"The temperature is rising." Eliza said looking at the small detector in the cage.

The two women didn't even realize they had stopped breathing. But when the mouse fell dead to its side, they both let out a long and deep sigh of deception. Eliza was the first to regain composure.

"It's ok, we know that the anti-virus is too strong or maybe there is something in it that is toxic and we didn't notice it." she said keeping her expertise in mind

"Right. Let's find out what killed this little thing." Alex affirmed determined to save her sister.

A few hours later, during their lunch break, the two women were sipping their coffee in Kara's room. Doctor Hamilton came it to do her check up routine.

"Her temperature is still rising. Fortunatly for us, the rise is slow and steady." the doctor stated

"I wish we could make her more comfortable." Eliza started. "Look at her. Her clothes are wet, her hair is dirty and sweaty."

"I'm sorry. We are changing her and cleaning her every day but the drugs aren't working as well as they should. Now, all we need is the cure." Hamilton said sadly looking at her patient

"Yeah... We had a pretty big evolution last night." Alex sarted. "We have the beginning of the anti-virus but we need to test it."

"That's very good news." the doctor said with her face suddenly hopeful. "I don't really know if this could help you but... You might want to know anyway." she added a few seconds later. "Roughly one time a day, Supergirl's heartrate and brain activity increase. Like she's dreaming."

"Alura warned me it would happen. She told me Kara would have hallucinations or dreams." Alex stated looking at her mother. "I just hope they aren't nightmares." she added shifting to her sister.

SSSSSSSSSSSS

When Kara woke up, she wasn't surprised to be chained to the wall with brand new kryptonite cuffs. Her headache was massive. She couldn't remember any headache she had in the past that would compare to the one she was having. If only this could be the only pain she was feeling right at the moment. Her body was on fire, Kara could feel the kryptonite in her blood intoxicating each of her cells. And her arm, God was it hurting. The young woman looked up to her shoulder and seemed confused when she saw her wound had been treated.

"They figured you couldn't handle the serum and the bullet so they chose." Alex said looking worried and angry at the same time. "Are you ok?"

"I hurt everywhere. How long was I out?" Kara asked with a weak voice, checking her sister for any possible wound she wasn't aware of

"A few hours. I don't know exactly." Alex started before wincing in pain. "They came back a few minutes after you passed out." she explained seeing the worried look on Kara's face. "They decided to teach me that trying to get out wasn't a good idea. And as much as I found their arguments convicing, I still disagree."

"Alex, I don't know if..." Kara started before feeling dizzy. "If I could do that again." she finished drifting back to uncounsciousness

"Hey! Hey, stay with me, Kara." Alex shouted to get her attention.

It worked a little. The young woman lifted her head again but closed her eyes.

"We're going to get out of this." Alex said both for her sister and for herself

"I don't feel... good." Kara said before lunching her body forward

"What is it?" the agent quickly asked a bit panicked.

The other woman didn't respond and instead, she threw up. After heaving a few time, getting rid of all her stomach contents and bile, Kara stood back, her head back against the wall, panting. Her face was screaming disgust. What was the last time she had thrown up? Probably years ago back on Krypton. Kara had forgotten the burning sensation in her throat and the awful taste in her mouth.

"How are you feeling now?"

"A little better." the young woman stated looking at her sister. "But...But I could really...use...a nap." she said with a lower voice after each word

"No, Kara! Stay awake!" Alex tried in vain.

The young woman was already uncounscious, her head falling to the side. The agent took a moment to observe her. Her skin was pale and greenish and the bandage on her shoulder had a stain of blood in the middle. Kara looked miserable in her torn suit. They had to get out of there and fast. Her sister couldn't take an other shot of kryptonite. Alex wouldn't tell Kara but she was in so much pain too. Her previously bruised ribs were know definitely broken and her blood was pounding in her head like her heart was in it. She certainly had a concussion among other bruises on her head, arms and legs.

An hour later, the door slamed open without any delicacy. In result, Kara woke up brutaly and looked immediately at the men entering the room. It was the same as usual, except for a man from the cleaning staff. Two gards, Max Lord, General Lane, and a trolley.

The cleaning man quickly wiped the ground where Kara had vomited and walked out as fast as he could. Clearly, he wasn't too found of working with monsters. The two guards walked towards Alex and cautiously unchained her. Exept for twisting her body in protest, the agent didn't make any move to escape. It would be stupid to try now that Kara could stand only because of the cuffs on the wall and Alex, in all her pride, had to admit that she couldn't take the four men in the room by herself right now.

The soldiers' gesture left the two sisters confused and it didn't go unnoticed by the two brains of the operation. While Lane stayed silent and smiled with all the evilness possible, Max claped his hands before explaining.

"We decided to change our tactics. Gentlemen, if you could clarifiy the next step of our interrogation please." he said motioning at the two soldiers

"Kneel down." one of them ordered to Alex.

But she didn't move. Instead, she glared at the soldier in front of her. He didn't wait long before slaping her in the face. Alex gasped and fell to her side. Kara tried to pull on her restrained and growled when she couldn't go further. One second later, the other man grabbed the young agent by her hair and forced her to stay on her knees.

"Thank you." Max said with a grin before looking at Kara. "Now we can proceed. Tell me where to find alien technologies."

Kara stared back at him with disgust and anger. It was all she could do to try not to appear as weak as she really was. But her body was betraying her. Her legs weren't supporting her, her arms were the only thing that was keeping her standing. The young woman couldn't really hide her fear of being injected again with kryptonite, glancing every few seconds at the trolley and General Lane. It was incredible how the man could stay so quiet and let Max do the talking. Sure the scientist had an ego to feed but he wasn't that calm and silent the times she had seen him at the DEO.

"Then you leave us no choice." Max said glancing over Alex.

As to illustrate his thoughts, one of the soldiers pulled out his gun and aimed at Alex. The agent only flinch slightly to express her sudden fear.

"No! Don't do it!" Kara yelled with panic and horror

"Then tell me."

The young woman was thinking too fast. She knew they would do it even if that meant to lose some of the DEO's secret in the process. But Kara had a very good knowledge on the DEO and aliens too. Alex was replaceble in some ways. She was looking alternately at the gun and Max. When the guard took a step forward and put his weapon directly against Alex's forehead, it was too much.

"Stop! Please stop!" Kara screamed. "I'll tell you. Please don't kill her." she begged crying

"Kara..." Alex breathed out

"No, I can't lose you Alex. I won't let them kill you, I can't watch them kill you."

"I'm listening." Max interrupted

"There is...a kryptonian recording device..." Kara started with a lower voice, trying to avoid Alex's look

"Kara, stop..." the other woman pleaded calmly

"It's in my apartment next to my bed. You can't miss it." she continued anyway

"Is there a message in it?" General Lane suddenly asked

"Nothing of your interests." Kara quickly spat feeling protectiv about the private content.

But a single look from Lane towards his men made her re-phrase her answer.

"It's personnal. It's a message from my mother. Nothing threatening about it."

"We'll be the judged of that." Lane assured before stepping closer the her. "Now. Tell me who is the other alien in the DEO." he ordered with a threatening voice

"Kara, don't!" Alex shouted but only earned an other punch in the face

"Alex, I have to. I have no choice." Kara said ashamed

"Don't sacrifice this secret to save me. I'm far less important than this agent!" the older sister continued, struggling against the guards in vain

"Not to me." Kara admitted staring at Alex's pleading eyes.

So that was it. Was Kara really going to expose J'onn so Alex could live an other minute? The agent wasn't sure on what to think about her sister. Sure, she couldn't imagine how hard it was for Kara to have her life at the tip of her tongue like that. But revealing such a secret, intimate name was insane and was basicaly treason.

"She..." the young woman started making Alex hide her confusion. "is a shapeshifter. Her name is Tan'ya J'onzz."

"I want more." the general commanded.

Kara sighed looking at Alex and faked a second of thinking before speaking again.

"She changes her Earth name and her appearance all the time."

"What does she look like right now?" Lane asked intrigued

"I don't know. She probably took an other appearance as soon as you kidnapped us... Alex, I'm so sorry."

The silence that followed informed everyone that General Lane had what he wanted for now. Alex glanced at Kara with a barely perciptible smile. She was impressed with how her sister had completely and perfectly lied to their interrogators, when she is usually a terrible liar. Also, if she could, Alex would applause for the use of true information to build her lie. Using J'onn actual daughter's name was a great idea. It would probably buy them some time before General Lane would find out this was a false information. But Alex's hope of little rest quickly faded away when Max walked in front of her, bending so he could see all the blood on her face.

"You know, I really thought I had a chance with you. Of course it was long before you decided to put me in a cell." he said with an evil grin

"You never stood a chance, Max. You're a digusting man with childish dreams and hopeless means." Alex spat staring at him with all the anger and rage possible

"Let's ask an other question, shall we. One that will benefit all of us." the scientist said trying to hide his own anger.

Alex smiled. She had obtained the little satisfaction of bringing Max to his uncomfortable zone. That's all she needed to feed her determination.

"Where is Superman's fortress of solitude?" Max asked straightening

"Try google map." Alex smirked.

She was about to get hit by one of the guards but Max stopped them with one hand.

"Tell me, or you're going to regret it." he warned glancing over the trolley.

Alex swallowed hard when she followed his look and then stared at Kara. The young woman looked with terror in her eyes and Alex could feel her panic just at the thought of behing injected again with kryptonite. This time, a lie wouldn't do any good. It would be to fast to verify. The two sisters knew it and that's why Kara nodded to Alex.

"Not. ." the agent said with her teeth clenched.

On that, Max lost his temper and rushed over Kara. Without warning, he punched her hard in the stomach. Kara cried out and jerked forward. Max shook his hand and turned back.

"Wouh, even without your powers, you're a hard one." he said before quickly walking next to Lane.

Kara didn't move from her bending position and this made Alex worry even more. The young hero was panting and soon began to take deep breaths, feeling the dizziness growing.

"Oh it looks like your little sister isn't over her first shot yet."

Two seconds later, Kara threw up again and when it was over, she looked up with a deadly glare, both to Max and Lane.

"You really should be more careful with what you eat." the scientist smirked

"I think we should ask the question to Supergirl. She seems more incline to answer correctly." the general proposed.

This was the signals the two soldiers were waiting for to pull out there weapon again and aim at Alex.

"Tell us where the fortress is." Lane asked

"Don't shoot her please. Don't do this." Kara begged feeling her eyes becoming wet.

The guard pressed his gun to Alex's forehead like he did before.

"No! Please don't do it!" she screamed now letting a few tears rolling down her cheeks

"Tell us!" Lane shouted impatient

"I don't know!" Kara yelled. "I don't know! I've never been there. He proposed me to go. I've always said no." she explained more calmly, taking the two men by surprise. "Please, you have to trust me." the young woman begged once more.

This wasn't a lie. Kara had really no idea to where the fortress of solitude was. Her cousin had never told her but had always wanted to show her. The only person who knew was Clark, James and probably Lois.

"I don't believe you." the general said calmly

"Yeah, me neither." Max added. "Do you seriously think we would buy this? You are his cousin, his last family. And you wouldn't know about it? That's very unlikely."

"I'm going to ask one last time." Lane said louder

"She's telling the truth. No one knows where it is except him." Alex interrupted suddenly afraid this might turn really bad for them

"Speak now! Or she dies." General Lane threatened moitioning to his soldier to push his gun more on Alex's head

"Don't! You have to trust me, I have no idea!" Kara shouted desperately. "Let her live. Kill me if you want but don't shoot Alex." she begged starting to cry again.

The general glanced over Max who nodded. Kara had more value than Alex anyway.

"Do you have a last word?" he asked to Alex

"No! No, Alex, run. Do something!" the kryptonian begged now fully crying

"Kara..." the woman said with defeat, looking down

"No..." Kara pleaded with a lower voice

"Kara, I love you so much." Alex said calmly turning her head so she could see her sister.

Unfortunatly, she also saw Kara's pain and distress. And it broke her heart. But she couldn't cry, she couldn't or it would make her sister feel even worse than she was now. Instead, Alex let a single tear roll down her cheek and stared at the crying woman.

"Fight for me." she simply said before facing her executioner and closing her eyes

A second later, the soldier received his signal and everybody stopped breathing. A single gun shot broke the silence and resonated in the room. Alex's body fell back. The woman was now lying on her back, her head facing the wall oposite to Kara. Her legs were folded on the side and her arms were resting on her stomach, still attached to one an other.

It took only a few seconds for the men to exit the room, leaving an astonished Kara alone with her sister's dead body.

"Nooooo!" She finally screamed.

It was raw and filled with sadness and desperation. Kara continued to scream until her voice broke. She started to cry heavily instead, still shouting her misery. She couldn't take her eyes off Alex. Kara stopped a second when she noticed the red stain of blood forming under her sister's head. Soon it would grow into a puddle. The young woman was streched between wanting to see her sister's face to be certain it was her and not wanting to see it because she knew already Alex was dead, and seeing her with a hole between her eyes would only horrify her.

It took at least thirty minutes for Kara to stop crying. She was now sobbing.

"Alex, why?" she started shaking her head. "I tried to stop them but I couldn't and I am so sorry for that." the woman added starting to cry again. "I failed you. I failed Cat... I was weak and now you're...you're...both dead." Kara couldn't believe what she was saying. "I love you so much, Alex. And I promise. As long as I can, I'm going to fight. They will not get any information from me." she finished with a light of determination.

But it quickly faded away when Kara looked once again at the dead body and saw the pool of blood. Instantly, she began to cry again. But more quietly this time. The young woman had left so much energy screaming her grief earlier and the kryptonite in her blood was so painful. She was too weak to continue. So, after ten minutes, Kara didn't even realize that she let her head fall on the side, and cried herself to sleep.

AN: Thanks to all the guests who post reviews, that's so encouraging! I really wish I could respond to you.

I know the thing about the Fortress of Solitude is weird but in my head, this happens between "For the girl who has everything" and "Solitude", and I guessed, since Kara never agreed to her cousin's invitation, that she never knew where the fortress was and that James showed her the way.

So here's chapter 6. Eliza and Alex get closer to the cure and OhMyGod I killed Alex in Kara's dream! I really hope this nightmare lives to the success of the last one because you seemed to be pretty affected by it. I can assure you, I almost cried when I wrote this one and I was so angry at myself for Killing Alex lol. Hopefully it's just a 't forget to tell me your opinion and reaction, and I will happily respond to you ;)

Next, things get rough for Eliza and Alex, Kara deals with her sister's loss and gets a new cell mate.
