Thanx for following this.

Lena's mind tried to make sense out of this conclusion: Did the Danvers raise Supergirl in secret? Was this the reason Kara and Alex had the Kryptponian on speedial?Like in trance Lena stepped forward till Eliza noticed her presence and turned around.

"Lena, thank you for bringing me here … for helping everyone…" she caught the distraught expression on Lena's face "Are you okay … as far as one can be right now?"

"You raised Supergirl?", she stammered.

Eliza wasn't sure if the CEO was mocking her or if she still didn't figure it out.
"Kind of. Supergirl was an identity, a symbol", Eliza admitted unsure what to do. "I took care of a child and told her not to be a hero", she sighed.
"I told her to keep her true self covered. My husband and Alex' told her, too. … We wanted her to be safe"

'and what about Kara?' Lena asked herself. But she realized that she never saw Kara and Supergirl together. Several times she worked or met with Alex and Supergirl but Kara was never around. Now Lena stood next to Eliza and looked straight into Supergirl's face. Her mind was spinning. Something was hidden in plain sight.

Eliza noticed the confused look on the CEO's face and followed her instincts.
"It's the mind that fools you" Eliza said and took her own glasses out of her pocket and held them over Supergirl's face. Lena couldn't believe it even after seeing this. That was Kara! It had always been Kara.

"Why haven't I recognised this? Even when I treated her wounds? … Why didn't she tell me?", Lena burst out.

"Lies of the mind … Alex doesn't … didn't recognise her either … and she knew"

"What? That's ridiculous. Alex would have known … She blamed Supergirl for letting Kara go there…good show"

"Because she doesn't know"

"Kara didn't trust me… And everyone else here? James, Brainy and J'onn. They took my help … They used me … They all made a fool of me … even in this situation… in my own building"

Eliza rose and made step towards Lena. "Kara was an alien but she was human like we all. Maybe even more like anyone else. After you fought with Supergirl about the Kryptonite she was afraid to lose her best friend. For a long time she would rather keep your friendship as Kara than telling you. But after Mercy attacked you she was searching a way to tell you. … Then the president demanded to know her identity and Colonel Haley left no doubt about that they would use Supergirl's next of kin and friends to blackmail her. So she quit. … But they kept digging and came up with an alien that prevented humans from lying." Eliza took a deep breath "So all agents who knew Kara's identity had her minds wiped of that information. … And Alex did too because she wanted to stay at the DEO – to protect Kara and the other aliens"

The CEO didn't know what to reply but finally found her voice. "So that's why Kara and Alex drifted?"

"Yeah. … I don't know if I can tell Alex now … she could go insane"
Lena's mind was racing.
"But that means Kara needed a friend even more!" Lena shouted

"She didn't want to jeopardize you and she didn't want to lose another important person in her life" Eliza explained. "Lena, I'm sorry I shouldn't have put that on you. That was selfish"

"It wasn't on you to tell this", the CEO replied and fell in silence. She was standing still but inside her was a storm consisting of different feelings raging: There was some much anger because she was betrayed by everyone. Disappointment because the person she thought was her confident didn't trust her all the way. But she was consumed with sadness either: she wasn't able to save her closest friend who had died by the thing she feared most: Kryptonite.

"Lena?", James entered the room and sensed that something had happened there.
"Are you alright? We need to hurry!"
Lena looked at him and made a decision. Even if her image of Kara was destroyed and she asked herself if she really had known her at all she had to admit that the side she had known was worth the promise she made to Alex – to make the persons involved pay. … And it would give her the opportunity to distract herself instead of yelling at everybody and throwing them out of the building.
"Thank you, for the talk Eliza. We will continue later" she said.

"What are you two up to?" Eliza asked concerned. "Lena, you shouldn't leave right now. Take your time to calm down and to settle"

"When Alex is done with J'onn she will come around. Everything will be fine … as fine as everything can be right now – right James?"

"Lena. What is going on? Are you fine to go? I can go alone"

"James, I made several promises today and I'm true to them", she said cryptically and turned to Eliza "See you Eliza. We'll be back soon" and shove James out the door and locked it.

Meanwhile in the same building...

"Alex, before I allow you to do this, I have to show you something in case your drug will send me to my ancestors", J'onn coughed.

"Not much confidence in my medical skills, eh", Alex chuckled suppressing her tears.
"What is it? Where is it?", she asked.

"Something about your sister. Her last words to you"

"What? I was told you weren't able to find her after the first explosion", Alex was confused.

"Sit. I will show you", J'onn said and held out his hand to Alex' head.
"First I will give you some memories back however that are just mine"

He showed her how Supergirl woke up after she had been captured by the DEO and her reaction to Alex presence. When Supergirl gave her the necklace during myriad wave – Kara's necklace. Alex' desperation when J'onn brought in Kara after the atmosphere was seeded with Kryptonite, Alex saying that she wouldn't lose her sister at this day.

"How is that possible?" Alex said in surprise. She felt that it was no imagination, she felt the Deja-vu. "Oh my god, how was this gone from my memory?"

"You wanted me to wipe it out when Haley wanted Supergirl's identity."

J'onn showed her the last moments knowing about Kara's alien heritage and Alex' sacrifice of the mind wipe. She was flooded with memories of her and Kara that were connected to the ones the Martian had transferred to her.
Alex was already trembling and J'onn exhausted.

"I have to warn you. This will be tough.", the Martian said.
Alex saw Supergirl – her sister - buried underneath the shelf and surrounded by the raging Kryptonite fire. J'onn was flying through the fire and landed next to the blonde woman.

"J'onn, …, what are you doing, leave before you get hurt", she coughed.

A little blue creature was standing by his side and sent a blue streak against the fire so J'onn was able to take the bars of Kara before the fire raged again.
"Ouch", he screamed. Again the little alien sent his freeze breath to the fire so the Martian could take Supergirl in his arms.

She just sighed in pain. "Don't. … Get out"

Again they were surrounded by green flames when a freeze stopped the flames for some seconds.
"Sorry, that was my last one" the blue alien said and ran out.

Kara was sighing. Her body had burning wounds and was spiked with Kryptonite. J'onn tried to fly but was too weak so instead began running. He felt the wave of the fire storm behind him and the burst of the explosion catapulted them through a wall. The Martian shielded her body with his own. Immediately he rolled himself from her but he saw life flossing from her.

"Help" he shouted desperately in the dark alley. J'onn kneeled beside her and between gasping for air she gave him a sign to come near. He took the remains of his cape and placed it under her head and took her hand.

"Where's James?" she whispered concerned.

"He's at the other side of the building. He's fine... He's coming", J'onn replied. She sighed and smiled at him with relief.

"Thank you J'onn, for everything you did for me and Alex. … Please take care of her. Tell her … she was the best sister I could have dreamed of … in the whole universe.", she tried to chuckle but mostly coughed blood. "She … she shouldn't be mad at me or herself. If it could endanger her or make her too sad don't tell her ever about the mind wipe, only if it's in her own interest. Watch out that she will be happy… Remind her that she will have it all", she gasped for air. J'onn was trembling. "Say goodbye and thank you to my friends … Eliza… my Mom…Kal … and keep an eye on them"

"Don't you dare dying on me, Kara", he said with tears in his eyes. "Alex will never talk to me again"

"You have to be more stubborn. … I'll watch out for you from Rao's light", she groaned with a forced smile.

"We love you. Stay with us, Kara." he said although he heard her heartbeat fading. Her injured body was shutting down.
She looked at him and opened her mouth to reply something but only a last sigh left her lips and the battered body became limp and still.

"Kara!" he exclaimed. "No"
After that J'onn broke down himself, lost his last strength and laid next to Supergirl. Even when Brainy, Lena and a group of paramedics appeared and took care of Kara and him his tears flowed. He knew she was gone for good.

Alex felt like she was knocked down. This transition had been as intensive as it had been her own experience. The whole time she knew something was missing. How could she be so close to her sister and forgot about the reason of her fear of losing Kara? That it wasn't just the vanishing of her father and the death that was part of her job? It wasn't just a fear created by the love for her sibling – just a few months ago Supergirl – her sister – laid fading away in front of her. She had taken risks and had been a target. ... And now she was gone.

Besides the pain it was causing him J'onn took her hand. "I'm sorry that I've given you a lot more to cope. But it wouldn't be fair to you and your sister if you had never learnt the truth. I'm not sure if your memories could have been accessible by a special incident. And I don't want to risk the chance that your memories are lost forever – because your relationship to your sister made you whole and Kara vice versa." he forced a smile.
"And your sister needs someone to say the prayer for the dead, to guide her way to Rao's light"

"How can I be whole again when she's gone?", Alex sobbed.

"Everyone who went before us takes a piece of us with them but we keep a piece of them as well", the Martian said.

"Alex, I'm missing your sister already. I'm very thankful that I had both of you in my life. Everyone would be proud of the Danvers girls to be his daughters. Alex, keep on being that responsible and kind hearted person. Fight for what do you think is right and don't forget to search a possibility to be happy. You deserve it", J'onn whispered.

"This is not goodbye, J'onn. You'll be sleeping for a while and be better than new", she chuckled but failed in suppressing her tears.
"You take a nap and in the mean time I sort out who did this to you and Kara. We got a promising lead", Alex said with emphasis.

"Don't let your anger guide you, Alex. Neither your sister nor I want you being harmed on a revenge path.… We rushed into a trap today and paid a terrible price. More caution is needed. This time there will be no one rescuing you if you're launching to space", he said with concern.

Alex tried to withstand his gaze but looked down. "Alex, in the current situation the leader of the DEO should oversight the investigation but don't lead it. … Please promise me that you don't do anything stupid or dangerous."

"Then you have to promise me to fight and hold on. … I need you. I don't allow you to leave me, too. This is an order", Alex said.

"I'll do my very best, director", the Martian replied. "Now do it"

Alex nodded and started the drip. She sat next to the Martian till he entered the coma.
"Come back soon", she whispered, carefully kissed an unharmed spot on his forehead and left his bedside.

We're on the finish line. Either one or two chapters to go!
