Thanx Jennifer Baretta!
So much for my planned one-shot, I guess I need two chapters to finish it.

Alex was standing on a balcony and gazing into the night. In this part of the city it was almost dark only a few lights could be seen. And it was unfamiliar silent. It was
the first time since two and a half hours she had the opportunity to process what happened. Everything had been right for her until she entered the apartment. How long had Kara been dead then? What was Alex doing in the exact moment? Alex closed her eyes and leaned against the railing. She inhaled the cool air and asked herself again and again if she wasn't supposed to feel that her sister was gone before being told? Desperately she tried to remember their last conversation and if she told her sister that she loved her. Lost in her thoughts she got surprised when Lena appeared behind her and said "I guess we both could use a drink" Alex turned astonished.
"It's just coffee" the CEO sighed "I know we need a clear head and to stay up for a while" she said and handed Alex a cup.

"Thank you." she took a sip and looked at Lena. "Although I would prefer a scotch, too. … When did we become so responsible?", Alex asked.

"That's my main impression of you. … Maybe that's why you were put in charge of a shady government organisation…"

"Tell that the president and … James and Kara", Alex said and asked herself why they hadn't called her, too.

"They didn't trust Haley – that had nothing to do with you. They wanted to provide quick help and keep you out of trouble I guess.… You blame yourself because you weren't there, don't you? … That's ridiculous. " Alex opened her mouth only to be cut off by Lena who continued "If you had been there then what? … You would have prevented everything?"

"We will never know"

"Alex, you could have been hurt or … dead too" Lena said with emphasis.

"Because I'm so responsible I just want to yell at somebody … but I know it won't help", Alex explained.

"Well, I'm here if you want to follow this urge. At least the main explosion was caused by artificial Kryptonite", Lena said and looked down.

"Do you have still Kryptonite? … Was it your Kryptonite?", Alex asked distraught.

"No my stock is complete. But the one from the crime scene is as pure as mine but less stable. … I proofed that it is possible to make artificial K. … I saw the damage first hand this stuff does … just how it drained Supergirl of every life force… we weren't able to get rid of all the pieces … I was able to provide destruction but not redo it … she basically died in J'onn's arms on the scene we were not able to relieve her … regardless how many shards we extracted", Lena told sadly.

"The kryptonite gas had doubtless great impact on her system, too. … Sorry to correct you in that but your mother had created artificial K before. You were just more successful in it", Alex said and continued "and the bad guys have been always aiming to do this. To have a ultimate weapon against Supergirl and Superman. However if it was a normal day I would yell at you for keeping this stuff"

"You should. Its likes killed Kara and hurt J'onn badly", Lena argued.

"Actually I would yell at Kara why she was so reckless to go in there … blame James and Supergirl why they had not hinder her … "

"James is already blaming himself"

"I know. And I don't want to upset him more … I know he's hurting"

"Yeah, and we tend to forget that Kara was an adult. She made her choice to go there. And you know why: because she wanted to help … because she had compassion… because she was on a crusade for truth" Lena added. "And I'm angry at her too … for leaving us", she said whispering the last part.

"Alex, do you read me?"

"What is it Brainy?"

"We got a description of the boss of the facility and we got a phantom sketch. I'll send it to L-Corp"

"Okay, Brainy. Wait a second, we just move to a screen" Alex said and turned to Lena "They got a phantom sketch" Together they headed to an office and texted
James who was handling CatCo business in one of Lena's offices.

"Here we are Brainy", Alex said.

"Here it is" he said and the sketch appeared on the screen "I just started facial recognition program"

"You don't need it" Lena said. "That is Vincent Sinclair … he is Veronica Sinclair's brother"

"Roulette's brother?" Alex asked.

"Yeah. Didn't write Kara a story about Veronica selling people to a slave planet and that she was beaten by Supergirl there?", Lena asked.

"I remember being on Slaver's Moon one time but the details are blurry", Alex replied. She felt that there was something more to it but couldn't lay a finger on it.

"Brainy, have we any intel if Veronica Sinclair aka Roulette has returned from Slaver's moon?", Alex asked via the comm.

"No, but in the future there is a legend that she was kept a prisoner till the end by the Dominators because of her failure" Brainy told.

"So this was revenge on Supergirl?", Alex asked.

"Well, you forget they were lured there via CatCo. So maybe this was on Kara, Supergirl or maybe on CatCo in general", Brainy concluded "When James gets to you, ask him if he recognises Vincent"

"Have you intel on his whereabouts?" Alex asked.

"Well there are several addresses and I will run facial recognition for all public cameras", Brainy said.

"Do it secretly. And when you got something pass the info only to me. I don't want to risk him getting away", Alex advised him.

"But if you withhold the information from NCPD or the DEO you will risk that he will get away … Alex, even if Haley has the oversight she is eager to figure out what happened and more important many agents declared they want do anything to help the investigation – due to respect to you and your loss – regardless what Haley will order", he tried to reason her.

"Give me a head start if anything serious comes up!" Alex yelled at the Twelve-Level-Intellect.

"But Alex, that doesn't mean he alone is responsible. Why should he blow …"

He was cut off by an alarm blaring.

"It's J'onn!" Lena shouted and ran off to his bedside with Alex on her trail.
