Hi guys, here's the next chapter. I got two requests that were kinda similar, and I thought it would be best to combine them into one. Thanks to both people who requested them and I hope you all enjoy.

Prompt: Alex suffers from PTSD and Kara helps her/Alex has PTSD attack while training with Kara, she increases kryptonite levels and beats Kara badly.

I feel like you all already know this from the prompt, but just as a caution this chapter deals with PTSD, so if that's upsetting or triggering to read to anyone I just want to make sure you're aware of it.

Alex stared at her reflection as she washed her hands.

The woman who looked back at her seemed distant, like it wasn't really her.

Her face was expressionless and no emotion passed across it as Alex watched the blood drain down the sink.

One of her agent's blood, agent Pearson.

He had been shot and killed in the attack that had happened a few hours ago.

Alex had been there, she could have saved him.

But she missed her shot, literally missed the attacker, and Pearson was struck down.

He was dead on impact, and deep down Alex knew that.

But the guilt-ridden, traumatized part of her refused to believe it and still tried to help him, pressing her hands into the wound as she called for help.

In the chaos of the fight around them, it was not other DEO agents who came to her rescue but Supergirl, who had been fighting with them.

Kara knew Pearson was dead when she got there, not only did she fail to hear a heartbeat, but the scene was…. gruesome.

No one could have survived that.

Alex told her to carry him back to the DEO, that there was still time to save him. But Alex knew there wasn't really.

Pearson hadn't moved, there was no pulse, and his eyes were staring blankly at the sky.

Kara pulled Alex to her feet and looked her in the eye.

"He's gone Alex, but right now we need to keep going," Kara said, knowing that they needed to focus on the task at hand, saving the city. "Are you ready?"

Alex nodded, wiping her hands off on her pants and picking up her weapon.

The terror of Pearson's death still fresh in her mind, Alex fought with more determination and fierceness than she usually did.

When the fight was over Alex returned to the sight to recover the body, she knew Pearson had a family, they deserved to at least bury him.

But in all the wreck of the fighting the body had been destroyed.

There wasn't even a body.

Alex pushed the images and thoughts from earlier that day away as she dried her hands, trying to ignore the red stain that still coated her fingernails.

Not that she hadn't lost agents before, she had.

And each time it ripped her up and tore her apart.

But this felt somehow worse, maybe because it had been her who was there.

She was the one who could've saved him, but she didn't.

Why didn't she take her time more, why did she miss? Alex never missed, but the one time she did someone died.

Feeling her mind start to spiral, Alex closed her eyes and pressed her hands against her eyes, trying to collect herself.

After a few minutes she felt like she had succeeded.

Taking a deep breath, she walked out and into the halls of the DEO.

Kara was still there, but Alex didn't feel like talking to her or anyone else.

She walked past everyone and headed for the door, there was no need for her to be here and she wanted to go home, to be alone.

At home she could fall apart if she needed to, but when she would walk back into the DEO tomorrow morning she would be collected and complete.

This was what she had learned to do.

When she needed to fall apart, she did so only when no one was around.

Not even her sister, Kara had enough to worry about without worrying about Alex.

As she neared the door Kara stopped her, "Hey you are heading home?" Supergirl asked, her voice taking on a gentler tone than usual.

Alex gave a smile and hoped her sister couldn't tell how faked it was, "Yeah, I'll see you tomorrow."

Kara held her gaze for a minute, "Ok," she said still using her concerned voice, "Have a good night, I'll see you tomorrow."

Alex gave her one more "see ya" as she walked past her and out of the building.

When Alex got home, she was shaking.

She didn't know when it started, but she couldn't stop it.

The iron-like smell of blood reminded her that she needed to shower.

Pearson's blood stained her pants from where she had kneeled in it.

The image and the feeling flashed in her mind and she felt sick.

She couldn't breathe, she couldn't stop shaking, she couldn't stop thinking.

It took her 20 more minutes before she got in the shower, and she stayed in there long after the water turned cold.

But she couldn't drag herself up off the floor, and she wasn't sure she wanted to.

Sleeping was not going to happen tonight, so why rush?

So she stayed on the floor of her shower, head pressed against her knees as her tears mixed with the now ice-cold water.

"Come on Alex is that all you got?" Kara asked with a smirk as she easily blocked her sister's attack.

The night before had been miserable for Alex, but like usual she came back to the world like nothing had happened.

Today was the day Kara and Alex usually trained together, and Alex had almost canceled it.

She didn't feel like it, but she didn't want to have to explain herself, so she didn't say anything.

They had been training for the better part of two hours, the kryptonite emitters on to make the fight more fair.

Still Alex was not at her best, her mind was still replaying the previous day's events, and every time Kara came at her, she saw the way the alien had come at Pearson.

Kara knocked Alex off her feet and Alex hit the ground hard.

"You ok?" Kara asked, reaching down to help her up.

"Yeah," Alex said breathless, but she didn't feel ok.

Images from not only last night but from the last several years still playing on repeat in her mind.

"I'm fine, let's-lets go again," Alex said, trying but failing to push the thoughts away.

This time, when Kara went to knock Alex's feet out from under her, she dodged the attempt, but the motion switched something in her mind.

She remembered doing the same thing months ago when someone else, a lot more dangerous, was attacking her.

Her heart began pounding faster than it should have as she kept fighting, forcing the intrusive thoughts out of her mind.

Her determination manifested in her fighting, and she started getting the advantage.

Like she wished she had done last night.

If only she had been faster, stronger, she could have saved him.

Her mind was racing a mile a minute as she kept fighting, unaware that she had even knocked Kara against the wall.

"Wow ok, you just kicked my butt, you wanna take a-" Kara started saying, but Alex didn't hear her.

Alex's mind was in a whole other world, the room around her had faded and all she saw was all the people who had ever tried to hurt her, who had hurt her friends.

She hit hard, punching Kara square in the face.

Usually it wouldn't so much as tickle Kara, but with the kryptonite emitters, they were pretty much equal, so she felt it.

"Ow Alex!" Kara yelled as she reached her hand up to feel her busted lip.

Alex still didn't hear her, and she just kept hitting.

"Alex!" Kara said, throwing her arms up to shield herself, "Stop what're you doing?!" She asked, but Alex said nothing.

"Alright," Kara said, moving over to the controls for the kryptonite emitters and turning them off, she ran back over to where Alex, who was now punching the walls in place of Kara.

Kara didn't know what was happening, but talking wasn't clearly working.

"Alex you gotta stop," Kara said, reaching behind Alex and easily held her arms back, wrapping her arms around Alex's body to stop her from escaping her grasp.

Alex screamed in protest for a second but her screams quickly began labored breaths.

Kara turned her around so they were face-to-face, still leaving her hands on Alex's shoulders. "What was that?" Kara asked, looking into murky brown eyes that looked below her.

"I- don't…" Alex looked up and saw the dried blood and Kara's lip from her initial punch, "Did I do that?" Alex asked, stepping out of her sister's grasp.

"Oh gosh I'm so sorry, I didn't mean to, I just… I don't know what happened, I just couldn't stop thinking about last night and I just lost control and oh crap are-are you ok?" Alex said in one panicked breath, still arms distance away from Kara.

Of course, Alex knew she didn't really hurt Kara, not permanently anyways. Kara was probably already healed from it.

Sure enough Kara said, "Alex it's already healed, I'm more concerned about you and what just happened." Alex stepped further back and ran her hand through her hair.

"I'm good, I'm good I just need to-uh I need to get some air." Alex said, and before Kara could respond Alex was out the door and down the hall.

Kara could easily follow her, but she decided to give her some space before going to talk to her later.

Instead she went to the bathroom and cleaned the blood off her mouth.

Alex sat and watched the sun drop below the horizon on the balcony of the DEO.

She took a deep breath, her mind was still going a million miles a minute, and she couldn't get it to stop.

She had hurt Kara, she had been the reason Pearson died, and she couldn't stop thinking about last night.

It wasn't just last night either, it was every other time when she had failed to save someone, or just every time she had almost lost someone, every single fight she'd ever been in.

"Alex," said a voice Alex recognized.

"Go away Kara, I'm good, I'll talk to you later." Alex responded, still staring at the sunset.

Kara ignored her and came to stand next to her, leaning against the ledge and looking out at the city below them.

"If you don't want to talk right now, that's fine, but can we at least take care of your hands?"

"Huh?" Alex said, looking at Kara and then down at her hands. She hadn't even noticed it, but her knuckles were bleeding, the skin on the back of her hands and fingers almost completely gone.

Guess that's what happened when you punch a rough steel wall with all your strength.

Alex looked back at Kara, who returned her gaze.

"Sure." Alex said, knowing deep down what Kara was doing and secretly hoping she succeeded.

Kara was trying to get Alex to open up, little by little, until she told her exactly what was going on.

And outwardly Alex didn't want that, but a part of her hoped Kara succeeded because she didn't have the strength to tell her herself.

Kara smiled and took Alex by the hands, guiding her to her private lab where Kara began cleaning and wrapping Alex's hands.

Alex let her.

"So, we gonna talk about this?" Kara asked, not looking up.

Alex rolled her eyes at how predicable her sister was.

"I just went a little crazy for a sec, I'm sorry it won't happen again."

At this Kara stopped, looking up to meet Alex's eyes.

"Lex, I'm not mad at you, not at all. I'm just worried."

Alex looked down, "Nothing to worry about Kara, I'm fine."

Kara waited, her eyes still looking at Alex's, who refused to look back up for several seconds.

When she did, Kara noticed unshed tears filling her eyes.

Kara gave her a soft smile before speaking, "It's ok if you're not fine. Its ok if your hurting, what's not ok is pretending like everything is fine and then having things like this happen." Kara said, her voice a lot gentler than usual.

This was a voice that she reserved for sad Alex, and it hardly ever got used because Alex was so insistently fine.

Alex nodded, a few tears dripping down the side her of check.

Kara brushed them aside with the pads of her thumb and rested her hand on the side of Alex's face for a second.

"So, let's try this again," Kara said, "What's going on?"

Alex took a deep breath, she knew she needed to explain to Kara what was going on in her head, and of all people she would feel most comfortable doing it with her sister.

But it still made her feel vulnerable, and she hated feeling vulnerable.

"I just can't stop thinking about it," Alex said, knowing that wasn't the extent of what was going on, but at least it was a start.

Kara nodded, "About last night?"

"Well yes, but every other night too, every other time something bad almost happened, or did happen, I just… I just can't stop thinking about it." she repeated, unable to continue looking at her sister as she spoke.

Kara noticed her uneasiness and didn't force her to meet her eye.

"Ok, that makes sense." she said.

At this Alex looked up, "What do you mean? Me not being able to control myself does not make sense."

"Alex," Kara said, resting her hands on top Alex's wrapped ones.

"You've been through some pretty serious stuff, a lot more than I even know about, and you care about the people that were involved in those things. So, it makes sense that the memories would bother you. It doesn't mean your broken, it means you care. What wouldn't make sense is if you were completely fine and not at all affected by it, then I might think you were a psychopath or something."

Alex laughed a little at the joke, looking down at their hands.

"Yeah, I guess that-that makes sense." she said.

"But Alex, just because it's expected doesn't mean you have to deal with it. You know you could talk to someone about it, it might help."

Alex gave her a look, "Like therapy, I don't need therapy, I'm fine-"

Kara cut her off, "You're not fine, you're hurting. But talking might help."

Alex nodded, more tears starting to fall.

Kara pulled her into a hug, and Alex savored the feeling.

Kara somehow always knew exactly what to do.

"Promise me you'll think about it?" Kara asked gently, her hand moving through Alex's hair like Alex usually did to her.

Alex didn't respond, but Kara felt her nod against her shoulder.

3 weeks later, Alex emerged from the building her sessions were in, looking around for someone.

"There you are," She said, walking over to where her sister sat on a bench.

"Hey, how was everything?" Kara asked, standing up and walking down the street with Alex to the restaurant they had found last week.

"It was good." Alex said, refraining from saying much else.

She had thought about therapy like she told Kara she would, and decided to go through with it, although it took a lot of convincing from her sister.

So every Tuesday for the last 2 weeks at 10:30 Alex saw a therapist, and it was actually helping, just a little bit.

She had been diagnosed with PTSD and been given some medication as well as a lot of advice and tips.

But mostly she just had someone to listen.

She knew Kara wanted to know the details of their sessions, but when Alex didn't give them Kara never pushed, and for that Alex was grateful for that.

Instead she met Alex after each session and they got lunch together.

Kara linked her arm through Alex's as they walked, "Oh I have to tell you what happened this morning," Kara said, "You are not gonna believe it."

Alex laughed, "With you I never know what to expect."

Kara gave her a fake scoff, "Well if you're gonna be rude maybe I won't tell you then."

"No, no please, I'm dying to know what it is." Alex responded with a grin.

Kara didn't need to be told twice, launching into an extravagant story about her morning.

Alex smiled as she listened, things were definitely far from perfect, but they were getting better and she knew she had all the support she needed, especially from a certain little Kryptonian sister.
