"What are you doing?" The teenage Alex asked Lena an hour later as she saw the CEO muttering at a screen.
"Welcome back to the land of the living." Lena said looking over at the teenager. "Are you feeling better?"
"A bit." Alex said before repeating. "What are you doing?"
"Seeing if there is a way we can use this gemstone technology to power our own suits." Lena said.
"We have suits?" The teenage Kara asked.
"Well, we could do. For now I have an old one I am working with." Lena said.
"Why does that have the family crest on?" Alex asked pointing to the suit.
"At one stage the atmosphere got polluted with Kryptonite and we had to put your mom in this suit to keep her safe. Despite its age, it is still a good suit. If I can somehow merge this gemstone then this suit could be the blueprint for the ultimate defence." Lena explained as Alex looked over the specs on the screen as she did so she frowned.
"If you put it there won't that cause a load imbalance? And regardless, don't you need to surround it with trivalent atoms?"
"Um, yes. How do you know that?" Lena asked confused.
"She's a genius." MJ said.
"I did this at school last year." Alex explained.
"Which is her way of saying humans are really dumb." MJ said.
"Well in that case why don't you read that." Lena said pointing to the screen. "And point out my mistakes."
"Okay." Alex said sitting down.
"What about us?" MJ asked. "Can we do something?"
"Umm." Lena said thinking.
"What about the simulations, I mean that is basically just FTL7 right?" Kara asked.
"FTL7?" Lena questioned.
"The game."
"This isn't a game." Lena pointed out.
"Well yeah, if it was it would be running on a higher spec machine." MJ pointed out.
"All you need is to change those parameters so that number reaches one hundred percent right?" Kara asked pointing.
"Well yes." Lena said.
"We can do that."
"Okay then." Lena agreed as Alex said.
"You missed a minus sign."
"What? Where?" Lena asked turning her attention to the other teenager.

With the aliens focusing their attacks on the child Supergirl started to lose focus and soon started taking blows as she shielded the kid.
As she fell to the ground she wrapped her body round the child as the aliens started to kick her body.
Just as she was starting to think there was no way out the kicking stopped. Looking up she saw the aliens on the ground before hearing a familiar voice ask.
"Need some help?"
"Ye- Ba- I mean, The Flash? You're here?"
"Catch up later?" He suggested before taking the child from his friend and speeding off.
As Supergirl got to her feet she felt a breeze and saw Barry standing by her side, this time without the child.
"Is there a plan?" He asked as the three aliens got to their feet. "I'm not sure that I will do so well without the element of surprise."
"We need to remove those gems." Supergirl said.
"Double team the one of the left?" Barry suggested.
"Sounds like a plan." Supergirl agreed.

"I thought we agreed no watching the news." Lena said when she saw all three children glued to a tablet.
"It sounded more like a suggestion." MJ said.
"It wasn't." Lena said pressing a button on one of her computers making the tablet lose it's connection to the internet.
"What happened?" MJ asked.
"Communications black out." Lena said. "This area is now a Faraday cage."
"But-" MJ started.
"No buts."
"How will mom contact us?" Kara asked.
"When she is ready she will come here." Lena explained. "Weren't you three meant to be helping me?"
"We finished." Kara said.
"You can't have done." Lena said.
"Take a look for yourself." MJ said pointing to the screen.

"That was tough." Barry said when they had finally subdued all three aliens.
"Tell me about it." Kara said still breathing heavily as sirens approached.
"You okay?" He asked feeling as breathless as Kara.
"Thanks to you. Not that I am complaining, but why did you decide to come back?"
"I saw a friend in trouble." Barry said. "And I saw a friend that wouldn't give up and that was a little inspiring."
"Thank you." Kara said hugging him.
"No problem, but once we have saved the Earth, then I go back into retirement."
"Fair enough. You think anyone else might come back?"
"We can always hope." Barry smiled before handing Kara the gem he had removed from one of the aliens. "You know how to reach me." With that he disappeared just as the DEO containment squad arrived.

As Alex finished up the debrief she saw Supergirl had fallen to sleep at the back of the room. She then waited for all the agents to leave before walking up to her sister and nudging her shoulder.
"Alex?" Supergirl asked opening her eyes. "Is the briefing about to start?"
"It's just ended." Alex said before asking. "Tired?"
"Yes." Supergirl said stretching. "The last two days have taken it out of me."
"Are your powers okay?" Alex asked frowning.
In response Supergirl used her heat vision to reheat her sister's coffee and said. "Yes."
"That's something." Alex shrugged.
"You okay?" Kara asked her sister.
"For now."
"You sure? Because you look, umm, not good." Kara said pointing to the swelling in Alex's face.
"I'm fine." Alex said. "But we need to talk."
"About?"
"When I went to get the kids they were close to one of Mongul's lieutenants. I created a distraction and, that's how I got this." Alex explained pointing to her face. "The thing is though, I think Alex saved me."
"She fought him?" Kara asked frowning.
"No. That's the thing. She was down the street. But does she or did Fels have any telekinetic powers?"
"Not that I know of. Why?"
"Because one minute I was being attacked, the next the gem stone was in Alex's hand."
"And you think she thought it there?" Kara asked, clearly not thinking it was possible.
"I don't know." Alex said before suddenly remembering she hadn't collected the gem stone.
"What?" Kara said, growing more concerned.
"I forgot to take the gemstone off Alex."
"Can it harm her?"
"I don't think so. But we should get to L-Corp." Alex said before pausing and adding. "There is something else as well."
"What?"
"After the gem stone was removed I took my chance and I killed the Lieutenant. I tried to stop the kids getting close, but there is a chance they saw."

"What's that?" MJ asked as there was a ringing sound.
"The doorbell." Lena said looking at the security cameras.
"Your safe room has a doorbell?" MJ asked.
"Yes." Lena said typing in a code.
"Is it mom?" The teenage Alex asked.
"It is." Lena smiled. "She'll be down in a minute."
"Is she okay?"
"Take a look for yourself." Lena said pointing to the screen that showed the adult Kara and Alex in the descending elevator.
"Isn't a doorbell a little low tech?" MJ pressed.
"That's what makes it secure." Lena pointed out as the doors opened and Kara and Alex stepped into the room.
"Mom." Alex said running to her mother only to find herself being hugged tighter than expected. "Can't breathe." The teenager protested as Kara held her tightly.
"Are you okay?" Kara asked loosening her grip slightly.
"I'm fine." Alex said. "But I think you need to train more."
"What?" Kara asked confused.
"You didn't do very well out there."
"I was kind of outnumbered." Kara protested noticing her sister grin at her as she hugged her own kids.
"And you needed help." The teenage Alex went on.
"Which I got tonight."
"That was Barry?" Alex said remembering the stories her mother had told her.
"It was."
"Is he going to keep helping?"
"I hope so." Kara replied.
"We have some more good news." Lena said. "I think we have managed to integrate the gem into the old Super suit."
"We?" The adult Kara asked.
"Yes, Kara and MJ ran simulations but a lot of it is thanks to Alex."
"What did I do?" The adult Alex asked confused.
"Not you." Lena said. "I meant Kara's Alex."
"What did you do?" The adult Kara asked her daughter.
"Not much." Alex shrugged.
"She pointed out that I didn't have enough trivalent atoms." Lena said. "Then corrected my math."
"Umm, what?" Kara asked.
"Your daughter is a genius." Lena said.
"But you have been getting average marks." Kara said confused.
"Yeah, perfectly average." The teenage Kara said.
"Kara and MJ said I shouldn't stand out." The teenage Alex said. "So being an average student seemed best."
"See genius." MJ commented.
"We need to talk about all the secrets you are hiding." Kara said looking down at her daughter. "Were you planning on telling me about your new power?"
"I did tell you last night, but you fell to sleep as I was talking." Alex pointed out.
"So that wasn't a dream." Kara said to herself before looking at her daughter again and asked. "You sure you are okay?"
"I'm fine."
"Although her new power seems to make her quite tired." Lena said, thinking the kids might neglect to mention that.
"Is that why you were so tired this morning?" Kara asked, looking at her daughter again.
"Maybe."
"I should get you home." Kara said before looking over to Lena and saying.
"Thank you for looking after them."
"My pleasure." Lena smiled before looking at the DEO director and asking. "Alex, can you stay back a minute. You too Kara. As in you." She added pointing to Alex's daughter.
