A/N: Thanks for the comments.
Alexfan - It will be a short wait...most of those questions should be answered in this chapter.
Guest - No one has faith in Kara's ability to do as she's told! But no Kara will not be going to Russia.
"Do you think they knew we were coming?" Alex asked as they walked through another corridor in what looked like an abandoned underground city.
"I don't know." Brainy said as he walked into a room.
"If you say promising I will shoot you." Alex warned.
"But there is a computer. That is promising." He argued.
"There has been a computer in every room we have been in." Alex pointed out as Brainy interfaced with a computer system. "Ahhh, this is what we've been looking for."
"You say that every time."
"This time I am almost certain."
"Finally, it feels like we've been here for days."
"No, just eighteen hours." Brainy corrected.
"Eighteen hours?" Alex asked surprised.
"Technically eighteen hours and six minutes. It is a larger base than anticipated."
"I guess I missed my keynote speech after all. I just hope they haven't done anything stupid." Alex said. "How long do you need?"
"This uses quantum based encryption. I didn't know they had this at this time. Intriguing." Brainy replied.
"How long?" Alex repeated.
"Ten minutes."
"I'm going to continue looking round. Stay out of trouble." Alex said leaving the room and continuing down the soulless corridor. After a few minutes of walking Alex felt a presence.
"Pree-vyet Alex." A familiar voice said from behind.
"Ty znayesh' kto ya?" Alex replied as she turned to face the mirror image of her sister.
"Of course. I have all of her memories. Including every wrong you ever did to her. The accusations that she was responsible for your father's death, the murder of Aunt Astra, how you ditched her for Maggie. I know it all."
"What do you want?" Alex asked.
"Really Alex? You think I'm going to stand here and bare my soul to you because you brainwashed me into thinking I was your sister?"
"Kara Danvers is my sister." Alex said.
"Only I'm not. I never was."
"You are not Kara Danvers." Alex pointed out.
"Aren't I? Don't tell me you've not figured it out?"
"Figured what out?"
"I'm not a new version of Kara Zor-El that magically came into existence from no where. I am as much Kara Zor-El as the Kara that lives with you in National City. What happened that day split us from one into two. Didn't you notice a change in her behaviour or are still so self absorbed in your own life to care about her? If she weren't so pathetic, so needing of attention I'd almost feel sorry for her. But as it I don't. Even if I did as my comrades asked and killed you right now I still wouldn't feel sorry for her. Oh, don't worry, I don't intend on killing you today...you are still too important to me."
"Important?"
"Yes, I want something from you."
"What?"
"You are the ultimate weapon."
"I don't understand."
"I know. Which is another reason you can't beat me."
"I wouldn't be so sure. You aren't immortal." Alex argued.
"That is true. But that has nothing to do with your inability to stop me. You claim to love your sister. If that is true you can't kill me as that would be killing part of your sister. Killing Aunt Astra you got away with. Killing part of your sister though? No one can approve of that. Plus we both know the annoying Disney version of me wouldn't approve. Face it I hold all the cards. There is nothing you can do."
"We will stop you."
"No you won't. But if I were you I would get back to the conference before people notice you are missing. I'd hate for something to happen to you, before I want it to."
"You're letting me go?"
"You mean nothing to me. Plus there is nothing you can do to me. Besides I think I want you to witness the fall of Supergirl."
"You won't beat Supergirl." Alex said.
"She is weak, she can not win. All I need to do is take those she loves from her. Maybe I'll kill you first, maybe Eliza or maybe dear old dad...I'll know when the time is right. The point is she is so fragile. Her love of you makes her vulnerable. Her love of you will make her bow before me and beg. What greater symbolism is there than that? Like with everything in your life, you can't win." She said before walking away.

"I got the SOS. What's going on?" Sam asked as she entered Kara's apartment.
"Alex is missing." Lena said as Kara paced the apartment.
"It's my fault, I should have gone with her.."
"You couldn't. You could have been recognised...or you could have triggered a war." Lena reminded her.
"That would be better than Alex being in danger." Kara said. "How could I let this happen?"
"Alex chose to go." Lena reminded her. "And you sent J'onn along as back up."
"Well that didn't do much good did it? I'm going."
"You promised Alex you wouldn't." Lena reminded her. "You said unless there was a clear signal or no contact for 2 days you wouldn't do anything."
"I know. I shouldn't have said that."
"If Alex has infiltrated something and you go in you could be risking her life." Lena went on.
"I know that."
"Alex will be okay." Sam said.
"You don't know that." Kara snapped.
"Alex is one of the strongest people I know." Sam said. "If she isn't okay, she'll find a way to be okay."
"I'm scared." Kara confessed.
"I know." Lena said hugging her. "But you are not alone and neither is Alex."
"What if it is my fault? What if this is the price for going back?"
"Going back where?" Sam asked.
"During the...that doesn't matter. But what if this the cost?"
"Kara you are not making any sense." Lena said as Kara's phone buzzed.
"I have to go. It's the DEO, they have something."

"Supergirl, that was quick even for you." Haley commented as the hero landed in front of her.
"Have you heard from her?"
"We have. The storm damaged communications, but she is now on her way back."
"She is?"
"She is."
"Is she okay?"
"As far as I could make out from a message that was short enough to go on Twitter." Haley replied. "Her connecting flight from London is due to land in eighteen hours. We'll hold a briefing after that."
-TBC...
