A/N: Thanks for the comments.

Guest (1) - Wisely, she hates spending time with kids. Also she is more focused on finding the scarab than taking revenge at the moment.

Guest (2) - Presumably he could have just asked Lex or Lillian or Maxwell Lord or any of the hundreds of other people who know.


"I thought you'd be here sooner. So did Alex." Kara's alternative said when Kara stepped into the room where she was waiting.

"Where is she?" Kara asked looking round.

"Through there. Don't worry, she's alive for now. I thought you would be more open for a trade that way."

"There won't be any trade until I see Alex." Kara said.

"I knew you would say that. Which is why I ensured she was on hand." She replied before using her heat vision to burn through a wall. As the barrier disappeared Kara saw Alex lying on the floor bound and gagged. As she looked at Alex she used her x-ray vision and saw a break in her arm. Turning to face her alternate self she was greeted by a smile and,

"I went for the left arm this time...it added a bit of symmetry."

"You will pay for this." Kara said.

"I doubt it." The alternate version countered. "Don't worry you can have her when I have what I want. Assuming you can figure out what I want."

"You want the Scarab." Kara said without missing a beat.

"Very good."

"It's a mistake." Kara said. "It is not the ultimate weapon you think it is. It will take you over and then contact the Reach. All it will do is bring invasion to this planet."

"You must have rehearsed saying that for a while. It was almost believable."

"It's the truth. If you don't believe me come back to Argo City."

"Your plan is to lure me into a trap and what confine me? Kill me?"

"All I am trying to do is protect this planet and Alex."

"As am I...well not Alex obviously. But I have no interest in destroying this planet. How can I rule what doesn't exist?"

"That's your plan to rule the Earth?"

"Please, try thinking big for once in your life." She said. "The Earth is only the beginning."

"Why?" Kara asked.

"Because I can and because I deserve something from the Universe. After everything it has taken from me, it's what it owes me." She then paused and said. "Join me."

"Excuse me?"

"Join me. I am you, well I was, you. I have all your memories and feelings. I know how lonely you are. There is no one on this planet, in this Galaxy who can understand everything you have been through. Except me. I went through it too. You no longer have to fight your demons alone."

"I don't want to take over the Earth."

"I know everything about you until the split. I know that despite all the words and the actions of being morally apart from everyone, that Mon-El was right, deep down you love the attention. You love being loved. You are a fraud. You lie about everything including your make believe family. You claim that Alex is your family, but when we were under the control of the Black Mercy it wasn't Alex in that world. It was our Kryptonian family, even Kal. Which you have to admit was kind of funny as when we needed him the most he abandoned us." Smiling she added.

"You can lie to Alex, lie to Eliza and J'onn, lie to the whole planet. But the one person you can't lie to is yourself or in this case ourselves."

"You're wrong. Alex is my family." Kara said.

"No, Alex murdered your family." She said before turning to Alex and asking. "Do you know why she forgave you so easily? It wasn't that she actually forgave you. Trust me. It was because she was afraid of being alone. But if she had pet you probably would have been tossed to one side."

"You're forgetting something." Kara said.

"What's that?"

"My dream, sorry, our dream, when under the control of the Black Mercy didn't have Alex, but we rejected that world for Alex."

"Out of obligation not love." The alternative version said dismissively. "Alex has betrayed you time and again. She resents you, she blames you for Jeremiah and that is why you fight."

"We're sisters and fighting is part of that. Just like mom and Astra." Kara countered. "You can focus on the bitterness and the fights and when things didn't work, but do that and you'll always be alone. But you don't have to be."

"You are suggesting I join with you?"

"You suggested the same thing two minutes ago." Kara pointed out. "We can work together as partners, as sisters. Together we can make this world better."

"A noble plan if your version of better matched mine. But we both know it doesn't."

"That's not why you don't want to join me. It's because you're scared. Scared of being let down. Scared of betrayal." Kara said.

"Don't pretend to know me."

"You're not bad, you're me, just wired a little differently." Kara pressed.

"I'm not weakened by those around me."

"No, but you are weakened by not having anyone."

"You think I am the weak one?" She asked incredulously. "I can destroy you with a single breath."

"But you haven't." Kara pointed out. "Which means you can't."

"Does it?" She asked, her eyes glowing red before she started to attack Kara.

"Well?" Haley asked.

"Nearly there." Brainy said.

"You do realise our Supergirl is not good at acting? It is going to be obvious she is buying time." Haley said.

"This is a highly sensitive piece of equipment. Normally it's range is 40 cm and the patient is stationary. In order to make the SNR high enough on a moving target at a range of 24.2 m is a highly complex task." Brainy argued.

"One you said you were capable of performing on a useful timescale." Haley reminded him as the screen flashed. "Tell me that is good news."

"The scan is in and it is as we thought, the other Supergirl's brain chemistry is very similar to the original Supergirl's brain chemistry when she was subjected to Red-Kryptonite."

"Which means?"

"The Harun-El split them in two, the difference between them is the wiring of the brain." Lena translated.

"Actually it did more than that. This is not good." Brainy said.

"What isn't?" Lena asked.

"She's unstable."

"I think most people in the city already believe that." Haley pointed out.

"He means physically unstable. Her cells are degrading." Lena explained.

"So we leave her be and problem solved?" Haley questioned.

"No, both of them will die." Brainy stated simply.

"How does the bad Supergirl dying effect our one?" Haley asked as Alura and Eliza looked on concerned.

"Their life force is connected. Both of them are showing signs of degeneration. But the alternate version is much more rapid."

"Why?"

"I can only hypothesise at this point." Brainy replied. "But it could be to do with the fact that our one spent time on Argo City, or it could be that the alternate version was given chemicals by the Russians to enhance her powers, which caused the acceleration."

"So you have no idea?" Haley said.

"That is correct." Brainy confirmed.

"How long before she becomes completely unstable?"

"Hard to tell, but if it is correlated with use of powers-"

"That fist fight is accelerating their death?" Haley finished for him.

"Indeed."

"Then I will stop them." Alura said.
