A/N: Thank you, thank you, thank you for all the sweetest and enthusiasm you show me-all the reviews, favorites, follows, and reads are SO appreciated. After the emotional trauma of the last two chapters I have something short and (hopefully) sweet for you. I would love to go crazy with sister fluff and happiness in the next update after everything I've put you through, so head over to the (finally updated) poll and let me know which prompt you want to read. :) If by chance I accidentally left your prompt off the poll just let me know, and, of course, feel free to submit new suggestions if you would like.

To the guests that left such kind reviews on the last chapter, thank you so, so, SO much.

Also, big thanks to Brittany for submitting today's prompt: J'onn accidentally hurts Alex in training pretty badly and Kara gets angry

I'd love to hear what you think!

"It's not that bad."

"Not that bad? Alex! Your leg is broken and—oh my god, are you crying? You're crying." Kara brought a hand to her forehead.

"Could be worse," the agent replied with a shrug that didn't quite hide her grimace or the salty tears pooling in her eyes. Her back was pressed against the floor, her brown hair scrunched beneath her. J'onn was kneeling at her side, shoulders slumped, eyes examining her form.

Training had been going well—or at least Alex's definition of well, with her breath ragged and her muscles burning. She and J'onn's transition into sparring had been welcomed. She'd felt springy and quick on her feet until J'onn had kicked with too much force and she'd taken an unexpected turn, so they collided with full force. His boot meet her thigh and she immediately felt a sharp stab spread like burning flame. She hit the ground before she could register anything but pain. All the angles, all the forces were wrong.

Apparently the snapping of Alex's femur spiked something in Kara's superhearing because the blonde had appeared before J'onn even got to apologize for the third time.

"I can actually see the fracture in your femur and I did hear it snap by the way," Kara said and made her way further into the training room, hand poised on her hip and cape fluttering behind her as she closed the distance. Alex turned her head and laughed softly at Kara's exasperated sigh, watching as the blonde rubbed a hand across her face.

Kara's eyes shot open. "Alex, Rao help me if you are laughing right now. Your bone has a crack in it. Your bone is in two pieces."

"Please don't remind me," Alex hissed and pushed off the sweat gathering at her hairline. The pain was radiating through her leg, fiery and hot. It almost made her want to throw up.

As Kara rolled her eyes and shook her head she took a step over, gaze now fixed on J'onn. "And you, you are the one that let this happen. You're supposed to be careful with her, you're supposed to protect her."

"Kara, it was an accident-" Alex tried, but Kara cut her off.

"You know she always goes harder than she should and you know she's not like us, you know it's our responsibility to be cautious." Kara paced across the floor, steps echoing and bouncing off the walls. She was always haunted by the fragility of human life; always tormented by the delicateness of their bones and the weakness of their immune systems, their skin, their hearts. It was too easy to spill blood or puncture lungs; to crack or twist or pull. It was too probable that every human Kara loved would slip between her fingers.

J'onn nodded. "I'm truly sorry, it was an accident and I should have been more mindful."

"We should have been more mindful," Alex corrected. Her voice was strained and breathy. The timbre immediately rung through Kara's ears and filled her with worry.

"I can't argue with that, you both need to be way more careful. Have either of you contacted medics, yet?" Kara asked, brows raised.

"I'll go now," J'onn said, putting a hand on Alex's shoulder before standing. "I really am sorry, Alex."

"It's okay," she said and shook her head, watching as he left.

As soon as the door closed and the sound thumped through the room, Kara turned to Alex. "You don't have to hold it in anymore."

Alex nodded and a sob choked its way through her throat, she squeezed her eyes closed and large tears fell from the corners and dotted the metal ground. Her shoulders shook, she pushed her head against the ground, her hair knotting, hand raising to press her forehead.

"How bad does it hurt?" Kara asked and knelt beside her sister.

"A shit ton."

"Take my hand, you can squeeze it as hard as you need," Kara said. She tapped her hand against Alex's and the brunette reached for it, without opening her eyes, curled her fingers around Kara's palm and squeezed.

Kara slumped against the floor, felt pressure from Alex's hand spread through her palm. "Does it hurt more than that hang over you got your junior year of college?"

Alex nodded.

"Hmmm." Kara ran a hand through Alex's hair. "What about the concussion you got in high school?"

"Still worse."

"Broken collar bone?"

"Hurts more."

Kara pursed her lips. "When that bullet grazed your arm last year?"

Alex shook her head.

Silence spread between them. The seconds were heavy, the air thick.

"Ohh! I've got one," Kara said. "How about the one time you got your ass handed to you when you challenged me to a game of Monopoly?"

Alex cracked her eyes open and let out a watery laugh. The blonde felt her heart swell at the sight of her sister acting a little more like herself. "We swore we wouldn't talk about that."

Kara grinned and returned a gentle squeeze to Alex's hand, swinging it lightly. "Sorry."

"My pride is still wounded," the brunette joked. "I'll never recover," she said through little hiccups for breath, but her statement was punctuated with a hiss and a groan as her laugh jolted her body and shook her leg. "Damn," she muttered and immediately twisted back.

The motion sobered Kara and she kissed Alex's shaking, squeezing hand. "It's okay, sis. You're going to be fine."

"I'm sorry," Alex murmured through more tears. "About earlier."

Kara shook her head. "I was just scared. I can't help it."

"I know," Alex said.

"You're so fragile—" the agent huffed in protest "—Oh, you know what I mean," Kara said. "I could lose you so easily, and then what would I do?"

"You would survive," Alex muttered through gasps, her voice quiet. "Just like you always do."

Kara closed her eyes, pressed her face against Alex's hand, ran a hand along the brunette's sweat soaked hair; and as the medics flooded the room and Alex complained about having to use a stretcher the words fell from Kara's mouth. "I wouldn't want to."
