A/N: Thanks for the comments.
Guest- I did consider Alex jumping in, but ultimately she had too much to do at the command centre. Plus, in my opinion, her focus will have shifted towards her children. That said if Lena's lab had been/at any stage is attacked Alex would/will dive into action.
"I thought you were sleeping." The teenage Kara said as she found her cousin in one of the smaller rooms watching the news. "And I thought grandma blocked the internet."
"I unblocked it." Alex said. "Mom hasn't been on the news for awhile."
"That's probably a good thing." Kara said. "She beat Mongul."
"But she got hurt. What if she isn't fighting now because she can't fight?"
"Mom will look after her." The teenage kara assured her.
"What if she doesn't make it?" Alex asked sounded defeated.
"She will." Kara said before noticing the crushed games controller in Alex's lap. Following her cousin's gaze Alex said.
"Sorry, I crushed it. I didn't mean to."
"It's fine." Kara said sitting next to her. "Seeing gaming is probably a bad idea. Why don't you teach me more Kathlikran?"
"What about MJ?"
"He can join in later." Kara said.

Opening her eyes Supergirl looked round the room to realise she was at the DEO. Seeing her sister she called.
"Alex?" As she did so she winced as her jaw started throbbing.
"Hey, how are you feeling?" Alex asked moving to the bedside.
"Floaty. What happened?" She asked unable to focus clearly.
"After your fight, you kind of collapsed and Barry brought you back here."
"How long was I out for?"
"Six hours."
"Six hours?" Supergirl asked as she tried to sit up only to regret it as the room started spinning and pain shot through her body.
"Easy." Alex warned easing her back down. "You solar flared."
"I did? When?" She asked suddenly aware of how painful her ribs were.
"I guess after the fight. You took some heavy blows in your fight with Mongul, bad enough that your body couldn't heal fast enough."
"I remember." Kara said before asking. "The kids?"
"Are fine." Alex said as Kara tried to get up again. "Where are you going?"
"To see Alex."
"Kara, you still need treatment." Alex warned as she pushed her sister back on the bed. "Right now the kids are at the safest location in the city. It is best to leave them there. It is still a war zone outside."
"We haven't won?"
"Not fully. After you defeated Mongul, a power struggle started and you became the target."
"I remember."
"After you disappeared, some of the Lieutenants tried to find you and others went for your cousin." Alex explained. "We were able to concentrate most of our forces with your cousin and Barry. Although the Lieutenants did win a few skirmishes we won many more and after awhile they retreated. Mongul's fleet has left orbit. But there are still many aliens, and humans for that matter, rampaging. It will take time to round them all up even with Barry's and your cousin's help."
"I should be out there." Supergirl said.
"You have no powers. And the only reason you want to move is because you are pumped full of painkillers. Hence the floaty feeling." Alex reminded her. "But you do have three cracked ribs and significant bruising, not to mention a possible concussion. You need to rest."
"Alex is really okay?" Kara asked not able to shake the images that Mongul had placed in her mind.
"I promise you that she is fine." Alex said as she pushed more drugs through the IV before Kara fell to sleep.

As the teenage Alex sat trying to fix the games controller she had broken earlier she became frustrated and swore in an alien language.
"I am pretty sure your mother would not have taught you those words." Alura said entering the room.
"You speak Grench?" Alex asked looking worried.
"Back on Krypton, I once tried a native of Grench and he used a very selective vocabulary of his native tongue."
"Sorry." Alex said looking slightly embarrassed.
"What is upsetting you?"
"I can't fix this." She said waving the motherboard from the controller. As Alura continued to stare at her she added. "And I'm worried about mom."
"So am I." Alura said. "But your mother is strong and you need to have faith in her."
"I do. But doesn't mean I am not worried. No one has seen her since that fight."
"Which you know how?" Alura asked.
"I saw." Alex said not wanting to give further details.
"Your mother was hurt in that fight." Alura said. "I imagine your aunt doesn't want her going anywhere until she is convinced she is fine. Especially when others are managing to defend the planet."
"I guess." She said unconvinced as she went back to fixing the controller. As she noticed the look Alura was giving her she asked.
"What?"
"You remind me of your mother. She used to spend hours in her father's lab playing with the equipment and then trying to fix the equipment she had accidentally broken."
"Mom?" Alex asked confused. "But science isn't really her thing."
"It was on Krypton. It was an excuse to spend time with her father. The two would spend many hours in his lab talking."
"What else did she do on Krypton?" Alex asked putting down the controller and looking at her grandmother.

"Do you have enough room for all these prisoners?" Barry asked as he brought another alien to the DEO.
"Not here." Alex said. "But we should at the desert facility. Can you start taking them there?"
"Of course. How's Kara doing?"
"She has no powers. But she did wake up." Alex said. "What about you?"
"Hanging in there." Barry said. "It's harder out there than I thought."
"Make sure you pace yourself." Alex warned.
"I will." He said before disappearing. As Alex turned she saw squad two limp through the control room.
"Which part of follow orders did you not understand?" Alex growled as she approached Ruby.
"It's not my fault the radio broke. I am not psychic." She pointed out.
"She did save me." Lewis said before deciding this was not a fight to get involved in and followed the rest of the team away from Alex and Ruby.
"How bad is it?" Alex said looking at Ruby's leg.
"Not too bad. Should be healed shortly." Ruby replied. "I know what you are going to say, but if I didn't do what I did we would have lost Lewis and one of the freaky gem things."
"And if it had gone wrong we would have lost both of you and two of the gems." Alex said. "This time the gamble paid off, next time it might not. You can't just charge in, you have to appreciate the odds you are fighting against."
"So all decisions should be based on statistics?"
"Yes." Alex said. "But in reality they won't be because we are people not robots. And there are times we will do incredibly stupid things for the right reason. Like you a few months ago. But what makes a good Agent is being able to alter those odds before you go charging in. When you are told to wait it isn't because we don't want to act, it is because we are trying to maximise your chance of survival. With time you'll figure out how to do that by yourself."
"So I'm not fired?" Ruby asked.
"Get to the infirmary." Alex said walking off.
