Chapter 6: Supergirl

Minutes had passed by the time Kara and Barry broke from their hug. Kara gazed into Barry's eyes as she finally said something.

"Thank you." She took a big breath. "That felt nice. Finally just putting it all out there." Barry laughed and smiled at this.

"Accepting what happened is the first step to moving on, isn't it?"

"Yeah," Kara agreed smiling at Barry. "So, anyway... wanna get something to eat?" Barry nodded.

"Sure, let's just…" Barry started saying before his phone interrupted him. It was Cisco. "Hey, what's up?"

"You might wanna find a TV and turn to channel 52," he heard Cisco say. Barry turned towards Kara.

"Come on," he insisted and headed out the restaurant, Kara following after.

…

Not long after leaving, they arrived at STAR Labs, stunned at what they saw. It was a newsfeed, showing no one other than Galatea, her armor still damaged but with slight repairs. She was also holding a woman in tactical gear with her left arm.

"This is a message to the one they call the Maiden of Might."

"Oh no!" Kara blurted out. "Alex!"

Barry, Wells, Caitlin and Cisco all looked confused at Kara.

"She's my friend! Barry, the one I mentioned to you before. The one that lives in Central." Barry gave Kara an understanding look.

"If you don't come back to face me within the hour, at the location where we last fought, I will not guarantee this woman's safety. Oh! And this time, keep the Flash out of it."

Without a seconds notice, Kara took off her glasses, ripping her shirt open, revealing the S on her chest, then speeding off, leaving her clothes behind.

"Kara!" Barry yelled after her, but she was already gone.

"Well…," Cisco said, expecting Barry to speed out after her. Barry gave Cisco a concerned look.

"If I go after her, I risk Alex's life," Barry reasoned.

"What if something goes wrong like last time?" Caitlin pointed out.

Barry was torn, almost frozen in how to deal with the situation.

…

As Kara flew towards the place they had fought the other night, she found herself getting more angry. It was bad enough that she had killed three people, but now she was threatening her closest friend. Galatea had gone way past the line. She finally arrived in the woods where she saw Galatea standing, Alex lying in front of her.

Kara's first instinct was to grab Alex in order to get her away, but she knew she would have to get close to Galatea without her possibly shooting Alex or herself.

"The last daughter of Krypton returns… this time to die."

"Not today," Kara replied angrily.

"You sure about that?" Galatea asked smugly. "Last time the Flash had to save you. You really think that you are gonna save her?" Kara was now glaring intensely at Galatea.

"I don't think. I know I can. And I will." As she said this, she flew as quickly as she could, grabbing Alex, and then using her super breath to blow back Galatea, then speeding away with Alex, dropping her a safe distance from the fight.

"You alright, Alex?" Kara asked, concern in her voice. Alex nodded.

"Yeah, I'm fine," she assured Kara. "Thanks for the save. Now get her." Kara smirked at this, flying back to face Galatea. She was pointing her rifle at Kara now, as Kara's eyes were glowing red.

"Look who grew a spine," Galatea mocked. "But that won't save you." As she said this, she fired several rounds, all of which Kara managed to barely dodge.

"You got some more?" Kara mocked. "I can do this all day."

She knew she couldn't keep dodging every single bullet and that eventually, she'd get hit again, which is when she noticed something. There was a small hole in her armor. Galatea seemingly hadn't covered it up properly when repairing. Kara took this opportunity to shoot into the hole with her heat vision. She made sure not to shoot too much as to not kill her. Galatea let out a howling scream and fell to the ground, seemingly unconscious. Kara breathed heavily now, as it seemed like she was defeated, when suddenly, she saw a green cloud of smoke appearing in front of her, and she quickly but surely passed out as well.

...

When Kara awoke, she was lying in what looked like some sort of underground prison. She got up from the bed she had been lying on, surprised when she saw Alex standing in front of her.

"Hey, sister. Nice to see ya wide and wake. I like the outfit."

"Where am I?" Kara asked, still confused, looking around the small room she was in. It seemed like the walls were laced with lead so she couldn't see through them.

"It's probably best if I explain that." Kara heard a manly voice say. The man stepped into the small room. He was a tall African American male, dressed in similar tactical gear as Alex.

"Welcome to the DEO, Division of Extraterrestrial Operations. We make it our duty to protect the planet from extraterrestrial life that threatens the planet. I'm J'onn J'onzz. You already met my second in command, Agent Alex Kent."

Kara was completely baffled by what she was hearing as she shook J'onn's hand.

"Wait, since when do you work for the government?" Kara asked, now looking at her friend, still confused.

"We're not part of the government." Alex answered. "The DEO is a secret organization, unknown to the general public and the US government. We stop the aliens that mean our planet harm… which of course doesn't include you."

"I can understand if you're not entirely trusting of our organization but Agent Kent insisted that we let you know about it now that you've faced off against Galatea." Kara suddenly came to realize where she had been right before passing out.

"Where is she?" Kara asked with concern.

"She's locked away in a cell within this facility, unable to harm anyone else."

Kara felt a bit more assured, knowing she was taken care of. "What will happen to her?"

"Well," Alex started saying, "we thought we'd retrace her steps. It was oddly enough through our radio signals, that she found about you. She must have intercepted us talking about Krypton, found out about all the rumors surrounding you and then came here."

"We managed to also obtain her ship a while ago," J'onn explained as Kara gave him a glare for not getting to the point. "We're gonna try and see if we can establish contact with a galactic prison, present evidence of her crimes and then send her away." Kara seemed pleased with this answer.

"I think I'm gonna need some privacy with my friend here, J'onn," Alex suggested. "I need to fill her in on the more personal angle of all this." J'onn nodded and headed out the room. Kara was scratching her head still blown away by this revelation.

"Since when do you work for a secret group that hunts aliens?" Kara blurted out. Alex looked at her like she was trying to decide how to explain herself.

"Look, Kara," she said. "I would have told you a lot sooner, but joining this group, I had to promise not to tell anyone, even family and friends." Kara gave her the same look she had given J'onn earlier. "I've worked here for 3 years."

"I thought you were working as a mechanical engineer in Central," Kara questioned her.

"I did at first," Alex explained, "but one day I intercepted a frequency using my homemade radio. You know, the one I showed you?" Kara nodded. "Well, I intercepted a signals coming from this facility. I couldn't believe what I was hearing. They were talking about aliens, some of which are living among us. They were defending us from them. And I thought you were the only one on Earth…"

"Why didn't you tell me then?" Kara interrupted. Alex took a deep breath.

"I was going to… but then I went looking for this facility. I was captured by J'onn and several of his soldiers. They said they would wipe all my memory of this place, but I insisted that I would be a great asset to their cause, with my engineering skills and that I wouldn't tell anyone. I did have to prove myself first though, training for six months, to become an expert markswoman and fighter…"

"So that's why we couldn't hang out for that six month period," Kara interjected.

"Exactly. After I completed my training, I could finally leave, reminded that I could still not tell anyone." Kara looked at her like she really wanted to ask something.

"Why did you want to join in the first place? Besides being capable?" Alex sat down on the bed Kara had been lying on.

"I wanted to protect you," she finally answered. Kara looked at her in confusion. "Some of these aliens are dangerous and powerful. Some could definitely cause you some major harm if not kill you. I mean, you almost got killed when you fought Galatea last time."

"You were there when it happened?" Kara asked in confusion.

"We intercepted your intercoms' frequency when it happened. We were on our way there but when we got there, you and Galatea were both gone. We were guessing the Flash saved you."

"Yeah he did," Kara said, smiling a bit.

"I knew you were going to fight super humans. I didn't know you had met the Flash."

"We call them metahumans. And I only met him recently," Kara explained. Kara then thought of something. "By the way, what was that green smoke you used against me to knock me out?"

"Sorry about that," Alex said feeling embarrassed. "J'onn's idea. He needed to be sure you weren't gonna lead anyone to our secret location. It's Kryptonite smoke. It's made from a kind of rock we call Kryptonite which is pretty rare. It's remnants from Krypton's core." Kara wasn't sure she heard right.

"Wait? Krypton? But all of Krypton was destroyed."

"Remnants of it were spread across the galaxy during the super nova and some of it has come to Earth through minor meteor showers. I should probably tell you that Kryptonite is pretty dangerous, and radioactive. It was a small dose we gave you, so it didn't harm you, but if you ever see a glowing green rock that makes you feel weak, you might wanna back off." Kara was baffled. For most of her life she had thought that nothing on Earth could harm her, and now she was learning a rock could kill her.

"I'm gonna need some time to process all this stuff, Alex, if you don't mind," Kara said as she scratched her head again.

"It's okay," Alex said, now standing up from the bed. "Look, I'm sorry I never told you any of this. I also promise you, even though J'onn and the rest of the DEO now know that I know a Kryptonian, I never told them your human alias." Kara smiled knowing she could trust her long time friend though she did feel a bit left out after hearing all the things Alex had hid from her.

"It's okay," Kara insisted, putting her hands on Alex's shoulders and then embracing her. "You've been my friend for too long to get rid off me that easily… though hiding that you're working for a secret alien hunting organization is certainly a good try." They both laughed at this as they embraced each other.

"Thanks," Alex said as they broke contact, "I'm glad you finally know. By the way, where did you get this outfit?"

"Your mom made it actually," Kara explained. "It was supposed to be a sort of formal wear to honor my family but I think I'm gonna use it as my crime fighting costume."

"You sure a cape and skirt is practical?" Alex questioned.

"Hey! If I'm gonna be fighting crime, I might as well look good doing it," Kara said and they both laughed again. They suddenly saw J'onn coming back into the room.

"Looks like the two of you have worked things through," J'onn said.

"It's a start," Kara said grinning still.

"Well," J'onn started saying. "You should probably fly back to Central City. Let the Flash know you're okay."

"Wait!" Kara blurted out. "How long was I out?"

"Just about 4 hours," Alex answered.

"Oh my god! They must be worried sick about me!"

"They?" Alex questioned.

"I'll explain later. Where are we anyway?"

"Not too far outside Metropolis," J'onn explained.

"Alright! I'll catch you guys later," Kara said and she was out the facility within seconds.

…

So there we have it. Alex and J'onn are in this universe. Yes, Alex and Kara are not sisters but they're still very close here, so they're practically sisters. This also gave me a way to introduce the Kents into this series. Next chapter is the finale. What will the future hold for all our characters? Also, for the record, I am working on a sequel to this story, so we'll see more of this universe in the future.
