A/N: Hi everyone, I hope you're doing well! Thank you so much for the reads, follows, favorites, and reviews (Also, to the guests that review-I read your comments and they mean so much. Thank you!). Special thanks to the guest who sent in today's prompt: An extension of the scene after their fight in the season finale.

I hope I did the prompt justice. I tried to find the episode online but I couldn't, so this chapter might not be entirely canon, but I tried my best. It takes place near the ending of the fight scene.

Just so you know, the poll has been updated!

I hope you enjoy, and I'd love to hear your thoughts. :)

Her diaphragm heaved in short, shallow breaths; blonde hair cascaded over her face, blocking out the sight of Alex. Kara's vision was, instead, a mix of gravel and wet pavement. She tilted her head, caught the moment when Eliza got through to Alex, and held onto the whispers that passed between them.

A few seconds passed as the two embraced before Kara heard the scuffling of shoes against the road. As she tried to sit up, her arms quivered, her side burned with pain, her body ached. A gentle touch fell upon her back and her shoulder; simultaneously hugging her and helping her up. Eliza.

The contact was warm and Kara caught her foster mother's eyes, comfort flooded her body and her breathing slowed. She wanted to be in Eliza's arms and holding Alex's hand. She didn't want the world to be falling apart.

Kara tried again to straighten up, this time with Eliza's help. Now Alex was close and kneeling in front of her sister with this heartbroken look tugging at her features. "I'm so sorry," Alex said, her voice cracking, gravel biting into her knees as she stooped on the pavement.

The blonde tried to say it was okay, but the words got stuck in throat, mixed with a heavy breath. Her head was still reeling, heart still thundering. The active kryptonite in her proximity made everything more difficult and painful. It was hard to think, her thoughts slippery and abstract.

Eliza moved a hand from Kara's shoulder to brush a strand of blonde hair off the girl's face. Kara looked at Alex, there was so much to say, her eyes were so heavy, her heart so full. The younger Danvers sister opened her mouth to talk, but her elbow buckled and her hand slipped. Her body jerked to the side and despite all attempts to stop it, a whimper escaped from her lips as she tried to straighten.

It was all coming down on her; the green kryptonite, the fight with her sister, the injuries.

Eliza was asking if she was okay and Alex was biting her lip, brows drawn in concern. Kara managed a nod against Eliza's shoulder as the woman pulled her into an embrace, held her tight, and Kara threaded her aching arms against Eliza, just trying to catch her breath and find the words to tell Alex that it was okay.

Kara had spent the past five minutes trying to catch her sister's gaze. The silence between them was glass—sharp and fragile. Passing seconds were punctuated by inhales and exhales and the soft hum of the dingy overhead lights. Kara suppressed a grimace as Alex tugged another stitch through her sister's side. Apparently, the green kryptonite Non had built into Alex's sword was the high-grade crystallized stuff, with a prolonged effect, preventing her from healing and sending pain bolting through her body, radiating from the gash spanning her side, where it felt like the green kryptonite had permeated through the open wound. Bruises had blossomed across her skin, blood still trickling from the cut she'd accumulated when she'd hit the brick wall and crashed against the ground.

Even though the kryptonite was gone, its effects were still lingering and Kara could feel every stitch that her foster mom and Hank and Alex had insisted she have 'just in case.'

"Sorry," Alex breathed out when she pulled another green k laced needle through Kara's abdomen and the blonde flinched.

"It's okay," Kara said, giving a small smile and trying again to catch her sister's gaze. The blonde was still feeling a little out of it, but the warmth of the room and removal of active green kryptonite was starting to help a bit.

Alex's moves were stiff and professional. She was being Doctor Alex and Agent Alex, Kara thought as she leaned back with a sigh. She wanted her sister. She wanted normal Alex.

Kara tapped her fingers against the metal table and squeezed her eyes closed, trying to distract herself as the needle pierced her skin again.

A drop of water splashed against her bare abdomen and she opened her eyes, glancing upward to search the ceiling for a leak. She squinted into the lights and began examining the beige tiles. She was on her sixth visual inspection when she felt another drop, followed by a soft sniff and oh, oh it definitely wasn't a leak.

Kara dropped her gaze so it was level with Alex. The brunette's face was turned away from Kara, her features obscured, but Kara could see Alex's hands as they closed the last suture and cut the thread. They were shaking. Hard. Her fingers quivered and Kara watched as her sister took a deep breath and more tears splashed onto Kara's skin.

Alex. Kara's heart thumped in her chest, her stomach sank. She felt herself sigh softly as she reached out and grabbed her sister's trembling hand.

"Alex."

The brunette shook her head and dropped the gauze bundled in her first. A long, shuddering wheezing breath vibrated through the air and Kara knew her sister was trying not to cry.

"Alex," Kara repeated and pushed herself into a sitting position. "Alex, it's all right."

Kara put her arms on Alex's shoulder and turned her around so they were facing each other. The agent dropped her head, casting her eyes downward. Her shoulders slumped, her arms hung limply.

"I have to…" Alex began and trailed off, reaching for a new piece of gauze.

"Wait, stop." Kara said.

Alex looked up, eyes watery and red. She sniffled and heaved a long breath, keeping silent. Kara took Alex's hands and swung them gently.

"Lex, it's okay. You're okay. Everything's okay."

"No, it's not," Alex breathed out and hiccupped.

"What do you mean?" Kara asked, pulling her brows together and sliding off the table so she was standing.

"I—I almost killed you today, Kar," Alex said, pushing tears off her cheek. "You could have died because of me, and that is not okay. It will never be okay."

Kara shook her head and wrapped her arms about Alex, holding her in a tight hug. The blonde could feel each of her sister's sobs, could hear each shaky inhale and heartbeat. Kara held her tightly but gently, in the balance she'd memorized so long ago; the pressure, the touch suited just for Alex. Kara let her eyes fall closed for a moment while she rubbed Alex's back, ran her hand over her sister's short hair. "Alex, it wasn't your fault. I don't blame you."

The agent sobbed in response and gathered the fabric of Kara's suit in her hand, squeezing tightly.

"Oh, Lex," Kara held her sister a little tighter. "Non was in your head and you were still able to fight him. You got him out. You did well, sis. It turned out okay," Kara said and her voice was soft and soothing.

Alex nestled her face harder against Kara's shoulder. "I'm sorry." She repeated, "I'm so, so sorry. Kara, I'm sorry."

Kara nosed Alex's hair. "There's no need to be sorry." The blonde kept holding her sister, hoping that somehow it would be enough.

"I love you," Kara promised. "And nothing can ever change that, okay?"

Alex nodded, her grip loosening.

Kara tilted her head, seeking out Alex's gaze. "Remember what you'd always say to me when I first got here and I'd feel guilty after messing something up for you?"

"We're sisters," Alex began, looking up and meeting Kara's eyes. "And family is forever."

Alex wrinkled her nose and cracked a small smile. "It's so cheesy."

"But it's true," Kara said with a grin and tucked a strand of Alex's hair behind her ear.

Alex gave another nod. "Yeah, it is." She patted the table with one hand and wiped her remaining tears with the other. "Come on, I'm still not finished with you."

Kara gave an exaggerated groan and pushed herself up onto the table. "See," she made a large gesture to the area her, "I'm already feeling better."

"Yeah, well, you're getting bandaged up, just in case," Alex said, gently wrapping Kara's side and dressing her stitches. "All done," she announced a moment later.

Kara slipped off the table again and gave Alex a serious look. "It really wasn't your fault. It wasn't," she said and pulled Alex into another hug at the sight of Alex's teary eyes.

"Let's go save the world, big sis," Kara whispered and leaned back to give her sister a grin.

Alex returned a watery smile and bumped her sister's hand. "Let's do it."
