Alex Danvers, special agent to an elite underground government agency put together to protect earth and alien citizens from any and all acts wanting to diminish life on the planet, stood in her living room swaying back and forth tiredly. Pajamas on, fresh faced and so, so ready for bed but the growing weight on her chest and in her arms had her pushing sleep aside. At twenty eight, this was one of the last things she thought she would be doing, maybe in a few more years and after lots of missions sure but not now.

A whimper escaped tiny lips, the air puffing against the side of Alex's neck. Glancing down at the blonde toddler in her arms before caressing the locks out of the girl's face. Tired blue eyes blinked a couple times but refused to shut.

"Come on, we have a long day tomorrow." Alex whispered as she ran the tip of a blue soother across the toddlers' lips but the girl refused to take it. Running her wet nose along the top of Alex's pajama shirt as she hid her face.

"It's just me here." The agent assured.

Blue eyes scrunched and a few more tears leaked out but the tiny mouth opened and accepted the soother. Alex sighed gratefully as the clock struck 3AM. Walking to her bed she placed the girl on the bed, wrapped the blankets securely around her and then lifted the installed medical railing to make sure the girl didn't roll off before she went to her side and crawled into bed.

Snuggling into the covers she glanced once more at the now sleeping toddler. Reaching out, letting her fingertips ghost across the girl's face to remove wisps of blonde hair fluttering along her forehead. A cute scrunch of the toddlers face had Alex still for a moment praying not to wake her up but instead the toddler just inched slightly closer to the agent's warm hand. A gentle smile played on Alex lips.

"I love you Kara." The words echoed in the stillness of the room, "We will get this fixed and take that stupid fifth dimensional being out of existence for doing this to you."

Kara just sucked on her soother and sighed contently, warm and cozy under the covers. Alex turned over and faced the ceiling, letting her body relax into the bed. She never imaged sharing a bed constantly with her sister but couldn't deny that having the younger girl with her or at least in her sights allowed for very peaceful nights of rest and relaxation.

Closing her eyes while trying to shut off her over active mind which flipped through how to kill a being no one knew how to touch, how grouchy her sister would be in the morning, if she would wake up this one time without a toddler draped across her body, and the final thought as she drifted off to sleep, how this all began.


ONE YEAR EARLIER:

The air was cool as winter approached. National City was beginning to set up for the holidays. Shop owners stringing lights across the front of their businesses and city workers putting up festive decorations on light posts and hanging banners across roads to indicate the Christmas Tree Ceremony being held in the park downtown. Crowds of people swarmed downtown sidewalks, some off to work, others to school and even more flooding the shops for presents and ideas or tourists meandering around and seeing the sites.

High above the city, a lone figure floated peacefully, taking in the sights, sounds and smells. The sun reflexed off the glistening water of the bay helping to warm the top atmosphere, "Supergirl, you there?"

Kara startled by her sister, Alex's, voice ringing through her ear, "What's up?"

"That's what I was going to ask. What you doing up there?"

"Relaxing." Alex gentle laughter is heard through the comms allowing a calm to settle deep in her bones. The small time away in Midvale really helped the two sisters reconnect even though they both were still hurting their connection was solidified again and that can get them through anything.

"Well, why don't you fly on over to the DEO, I have a project I need your help on."

"On my way."

The wind swept over her skin as she flew leisurely toward the towering building of glass windows located in the heart of the city. Sometimes it still surprised Kara that no one noticed her coming and going from the top floors or that black vehicles with tinted windows drove from the bottom garage out into the night but if the citizens of National City needed to turn a blind eye then she wasn't going to dwell on it either.

Her feet landed on the solid floor of the top balcony where the glass slid up to allow entry. The DEO was busy as usual with the daily grind, even when the city wasn't under attack there was much to do. Paper work, experiments, prisoner transfers/feedings/bathing and such.

"A little early for lunch," J'onn stated as he turned from the computer console he'd been standing over.

"Alex said she needed some help,"

He nodded and turned back to what he was doing before she strolled in. With everything going on in her life Kara was still a bit distant and J'onn was one of the only people in her life not pushing for more, he allowed brief interactions and simple words to be exchanged but even so the conversations were meaningful and helpful and sometimes just a needed break from emotional.

Spinning on her heel to head toward Alex lab where she was sure her sister was holed up but within two steps she was blocked by a very familiar figure, "How did you…"

Her words trailed off as everyone else in the area seemed to notice the intruder, guns flew up pointing in their direction, J'onn's face masked and he came to almost guard her back, while Kara could hear the heartbeat of her sister hammering away as she rushed to the side railing before running down gun drawn as well to stand across from Kara.

"Now is that anyway to treat an old friend," The man jested with a glint in his eye. Standing straight, proud and not in the least bit scared of the agents around him was the Music Meister.

"Friend…" Kara scoffed, "You almost got me killed."

Those words were not taken lightly for the agents in the room, for someone to almost take down their city's hero, well a lot of agents would lie but their hands shook slightly.

"You almost got you killed… and I prefer to call our last encounter a…lesson and speaking of," he smiled, "Your brokenhearted emotions have been flooding the air ways and it's getting me down." His body moved slowly around Kara, all the weapons following his movements.

"You're here to help?"

"Yes."

"Why don't I really believe you?"

"Kara, Kara, Kara….I helped before did I not."

The superhero adjusted her stance but could not really deny his claim, though it eventually led to heart ache, at the time his 'assistance' certainly put things in perspective. Kara was not going to tell him that, "I don't want your help."

"Too bad." The Music Meister grinned before snapping his fingers officially knocking the girl of steel unconscious, her body tumbling to the ground.

"What did you do?" Alex growled, her weapon pointed a bit more firmly at his head.

He turned slowly to stare at the agent before him, tilting his head as his brown eyes regarded the woman. She was strong, caring, and loyal. Everything he knew and felt toward Agent Danvers radiated off of Kara Zor El and that was all he needed to feel to know that the only person who could help was standing before him.

"Let's just say I've made it so she doesn't have to be so….restrained."

"And that means?" J'onn asked from his spot leaning over Supergirl.

The Music Meister's smile softened, "Her body is now absorbing the yellow sun as if it was a red one. She will go through two stages until her emotions are back in balance and when that happens I will feel it and will return to make things normal again. Until then…"

He spun on his heel, the handkerchief in his pocket fluttering a bit on his chest, "Agent Danvers is now officially the older, stronger, rock in which our sweet Supergirl will no longer have the need to restrain herself. She may let go and be caught." These last few words directed right at Alex, "So Agent Danvers….Catch!"

The man before all the DEO vanished, as if he were a dream because not one eye had left the hostile gentleman and yet no one could explain how he was no longer standing before them. The only remaining evidence he had actually been there was the downed super hero.

"Alex…" J'onn called putting the young woman back in action. She bolted from her spot, holstering her weapon as she came to kneel next to her Martian boss. Her brows shot to the top of her hair line and a gasp escaped parted lips.

Kara lay unconscious and transformed. No longer was she twenty six, strong, defined, a picture of young womanhood wrapped in a bubbly yet muscular body but was now a small, undefined, soft preteen, almost the exact representation Alex remembers from when Kara first arrived on Earth as a scared twelve year old who had just lost her entire planet and way of life.

"Kara?" The older Danvers slightly tapped her sister's face before finally running her fingers down the girl's cheek. The super hero groaned, shifted, and then deep azure eyes peeked from fluttering eye lids.

"What happened?" Kara groaned, her head was pounding, her eyes burned as she closed them again before fluttering back open to see her sister hovering, "I'm guessing he's gone?"

Alex was well aware this was going to be one of her toughest challenges; yet in the end if this could help her sister open up and not push her away, to be able to really feel for a change instead of constantly worrying about her powers getting in the way and hurting someone, than Alex Danvers was ready and willing to take this challenge on.

"He's gone." J'onn stated as he stood up. Kara shifted again, sitting up fully, getting a bit dizzy.

"That guy…" the super hero wasn't even sure where she was going with that sentence, she just wished he would start minding his own business and stay in whatever dimension he comes from. Standing up she was a bit wobbly, something felt off in her muscles, she felt weaker almost like the time she had solar flared. Shaking her head to rid herself of the dizzy feeling she finally glanced up at her sister, "…Alex?"

She had glanced UP at her sister.

UP.

Alex had not been taller than her for a few years now but this…this was, Alex was now much taller than her, in fact everyone in the DEO seemed to be relatively larger than her.

"What is going on?" Kara squeaked, eyes darting round.

"Come on. Let's go to my lab." Alex officially grabbed Kara by the hand yanking her away from the growing crowd who wanted to see their hero now reduced to the size of a child who seemed to be wearing a Supergirl costume.

Kara tried to stand her ground which usually resulted in Alex snapping back into place but not this time, the blonde's body jerked forward and in her shocked state her legs did not follow causing her to tumble forward. Alex turned and quickly righted Kara as if the girl almost weighed nothing.

"What was that? How did..." Kara tried to yank Alex back toward her but the older woman hardly swayed…she tried to fly. Nothing. She tried her heat vision. Nothing. Freeze breath. Nothing. Panic began to grip the young kryptonian's body. "Where are my powers? Why are you taller than me?"

"Kara…" Alex tried to get her sister's attention but the girl was quickly losing it. Kara's hands were moving quickly and questions pouring out so fast Alex was sure the girl would hyperventilate if not slowed down so she jumped forward, clasping her hand over her sister's mouth and her other hand positioned behind blond locks to officially confine Kara in a staring contest, "Kara…" Hazel and Azure eyes locked, "Try to calm down…let's go to my lab okay?"

Kara felt her heart beating rapidly in her chest, sweat beaded on her forehead, she felt slightly claustrophobic yet safe secured in the death grip Alex seemed to have on her. She nodded her head in agreement. The older woman slowly removed her hands from around the blonde's head, reaching her hand out for Kara to take.

The younger girl latched on, her clammy palm felt weird to both of them. Alex had never felt her sister's skin slightly on the cool side and more pliable…human and Kara had never felt Alex more firmly, usually all touch seemed distant, a slight pressure but now Alex felt real, tangible, solid….safe. The two now quietly made their way up to the lab away from all the prying eyes of the DEO.

Thanks for reading. Trying to get back in the swing of things, haven't written in a while and this is a first for the Supergirl Fandom. This story will probably be short, not sure how many chapters but if you guys have any scenes or suggestions you would like to see to stretch this thing out a bit I welcome them in the comments. Just remember Kara will still be her adult self to a point, memories and actions, though emotions will run high now that she isn't exactly in control.
