A request from Krolina in which a shy girl gets turned into a child via Hange!

I use Snow as the stand-in name. Different story, different person, same name. I hope that makes sense.

Please enjoy!

Where Is She?

"Where is Snow?"

It was the question of the day. Most of everyone participated some way in looking for her. She was last seen cleaning along with everyone else in the castle until Hange sought her out, thinking she was the perfect candidate for whatever it was she was planning. She was hesitant, but the scientist almost quite literally dragged her away. Everyone knew how much of a handful Hange may be, she might even be stuck with her the rest of the day, so she was assumed to be seen by tomorrow.

But no one had heard hide nor hair about her.

By the time breakfast came around, most of everyone was curious. Snow didn't normally miss breakfast. In fact, she would get and be sad until lunch if she missed it, so that rung a little red bell in her friends. By the time training came around, literally everyone became aware of Snow's disappearance. Some of her friends even took the liberty of using their break time before training started to take a look around and search.

"Where is cadet Snow?" Lieutenant Levi narrowed his eyes as he rounded their newest recruits.

"We haven't seen her since yesterday, sir." Armin volunteered to answer.

"She's been missing since yesterday and you brats didn't say anything?"

"W-Well, Lieutenant Hange had called her yesterday..." Armin continued to be the cadet's willing spokesperson, but had started to get intimidated by Levi's newfound irritation.

"Separate yourselves into groups of two and begin training. When I get back you had better be well into it."

Levi scowled as he walked away. Of course this involved Hange. Why wouldn't it? He searched outside with the captured titans, but didn't find her there. He scoffed in irritation, finding Moblit on his way back inside.

"Oi." he called his attention. "Where did shitty glasses go?"

"Lieutenant!" he saluted. "The Section Commander is visiting Commander Erwin."

Levi quickly made his way to the Commander's office, his irritation steadily growing. He swears that if Hange doesn't know where Snow was...He tossed the doors open forcefully as soon as he could reach them, instantly spotting the standing Commander in front of his desk and the person he was looking for, sitting in a chair in front of said Commander's desk. The glaring man locked eyes with the scientist, who had turned her head toward the doors when it opened.

"Where the hell is my cadet?!" he demanded, but stared dumbfounded at a small child sitting on her lap when he came around. The babe was currently wrapped loosely in a blanket and trying to disappear into Hange's shoulder. She tried (and failed) to sneak a peek at Levi, then quickly went back to Hange, stuffing her face in the crook of her neck when she quickly noticed Levi was staring directly at her.

Instead of verbally asking, Levi raised an eyebrow at Erwin after giving the small child a good up and down. Erwin answered him by silently giving his attention back to Hange and Levi followed his lead. Hange nervously smiled.

"Funny story about her..." the scientist nervously laughed, her unoccupied hand rubbing the back of her head. She stopped when Levi sent her another glare. "S-Snow."

Hange nervously called your name, which confused Levi until the small child in her arms responded with a soft, "Noo..."

Levi was dangerously close to strangling this woman. Erwin was certain—judging by the intensity of the anger in Levi's burning eyes—that if the babe wasn't in Hange's arms, he would have jumped the scientist.

"Snow." Levi grounded out between his teeth.

"Nooo..."

Levi clenched his fist and Erwin was sure he was about to shout, but Levi instead closed his eyes, exhaling through his nose. After, he knelt in front of Hange, speaking in a soft tone.

"Snow." he repeated, she softly grunted in response. "Look at me." He waited a moment, but spoke up again when she didn't move, his voice even and still soft. "Now."

Slowly, she turned her head to look at him. Her eyes were a bit teary and surprisingly, Levi's eyes softened a bit at her expression. He realized he may have startled her with the force he put behind opening Erwin's office doors.

"Do you know where you are right now?" he questioned. She nodded. "Where?"

"Daddy's room."

Wha—Who the fuck was—Levi whipped his head around to look at Erwin. His Commander had both his palms pressed on his desk, while his eyes screamed, "Don't look at me, I have no idea what she's talking about.".

The expression almost made Levi chuckle, but fine. Whatever. "Do you know who I am?"

She nodded again. "The top knight."

Levi raised an eyebrow. "Why am I "the top knight"?"

"You're the stwongest and you fight fow the castle."

Ok, well, that's not bad logic and this at least confirms that she has the basic idea.

"Do you know who's holding you?"

"Mommy."

Where was she even getting this stuff from?!

"Why don't you let "Daddy" hold you? I have to talk to "Mommy"."

Hange gulped, feeling as though Levi's anger just got worse. She was fearful to get an earful from Erwin, but Levi was much more terrifying. She shot Erwin a pleading glance, she would much rather be scolded by the Commander, but the man ignored her, instead going up to her and carefully scooping Snow, blanket and all, into his arms. She deserved whatever Levi had coming for her for turning one of his more talented soldiers into a toddler. He shifted her so he was carrying her securely, hand under her and the other on her back as Levi gripped Hange's arm and dragged her out of the office, anger back in his eyes.

"L-Levi, I can explain!" Hange tried to hastily explain, but he silenced her by glaring at her once again and he pushed her through the door first, then closed the door behind him with more force than he meant.

Erwin felt the toddler jump, immediately trying to hide her face into his neck, her arms going around his neck. Erwin sighed through his nose.

What exactly was he supposed to do with her now?

He used the hand on her back to rub her back, trying to ease her sudden fright. He sat down after thinking that he can't exactly walk around with Snow in nothing but a small blanket, so he settled for completing some paperwork. She was conveniently pressed against him and was small enough that it was easy for him to look down at what he was doing. Eventually, she shifted—which forced him to pause what he was doing—to sit on his lap and lean against him. He found himself thinking that she must have been an easy child to raise if she was this well-behaved. After another moment, he took a break, leaning back in his chair. He constantly kept a hand on her, even while sitting. He began to absentmindedly stroke her with his thumb as he thought on what was going to happen from here. Was she going to eventually go back to normal, or was she going to have to grow up again naturally? Erwin pinched the bridge of his nose, exhaling through it. Accident or not...Why does Hange have to add such unnecessary stress?

Snow shifted once more, sitting up on her knees on his lap. She reached up and cupped his cheeks with her small hands, instantly snapping him out of his thinking and giving her his attention. She looked into his eyes with the most innocent orbs he thinks he's ever seen in his life. Thinking about it, most children her age must wear that same innocence, right?

"Evewythin s'ok, Daddy." her voice was high and she spoke a bit slower than she used to. "Mommy will be back soon."

Was she trying console him? Perhaps because he seemed distressed. Did she think it was because he was worried about "Mommy"?

...

Erwin smiled at her. If he ever has a chance to become a father, he wants a child just like her.

Levi came back thirty minutes later to report that he made "Mommy" go to town and buy Snow some clothes. Hange had revealed that she had her take some kind of concoction she had made and she wasn't exactly sure of when the effects will wear off, but it will. Both Erwin and Levi were relieved, more Levi than the Commander because the Lieutenant didn't just witness the potency of a pure soul. Levi entered the room to find the toddler and the Commander smiling at each other after all.

Hange returned just in time for dinner and promptly got Snow out of the blanket and into a simple, light pink dress. She also bought her white socks and white shoes, so she didn't have to go around barefoot. She wasn't completely sure if the clothes she bought would fit, but she was extremely relieved that everything she bought did. Snow had complained about her hunger as she dressed her and she had told her that she'll get some food as soon as she's dressed. Erwin couldn't go too far from her without her quickly getting upset and had to reassure her that "Daddy" was just outside the door. Levi, Hange and Erwin quickly learned that Snow was a Daddy's girl and Levi gave the Commander the stink-eye when the man seemed to light up at the idea.

As Snow neared the mess hall and heard chatter, she slipped behind Erwin's leg, trying to conceal herself and forcing him to be aware of how he walked as to not accidentally hurt her. Trying to hide did nothing when she and Erwin entered. It didn't take long for the cadets to notice a little girl clinging to the Commander's leg.

"Sir?" Armin once again spoke up first, his sharp eyes one of the first ones to noticed. "Who's that little girl?"

All eyes suddenly flew to her and she fidgeted in place, now trying to desperately disappear behind his leg. Armin hoped the girl wasn't related to Snow's disappearance, but he had a sneaking suspicion that she was. Erwin nodded, silently telling him that he will explain in a moment. He walked to the front where he was easily visible to everyone and began speaking loud and clear.

"Attention!" he called. "An unfortunate accident fell upon one of your fellow soldiers. She was known to be missing up until a couple hours ago when she was brought to my attention." With little effort, he picked you up from behind his leg and cradled you in his arms.

You whined against the surprised stares and hugged into Erwin once again, her face buried into the crook of his neck. Some of her classmates let out surprised gasps. There was no denying that Snow and the little girl looked very alike, even having the same hair and eye color, but the babe was slightly chubbier.

"Snow has associated Lieutenant Hange and I as her parent figures. We will continue to work with her until she returns to normal."

Her friends so desperately wanted to go up to her, but refrained themselves. They wouldn't want to surround the Commander and risk punishment.

Sasha's hand shot up, eager to ask a question. Erwin raised an eyebrow, but let her go ahead.

"Can she speak?"

"She speaks fluently."

Several more hands shot up. Erwin resisted the urge to sigh. He shouldn't have answered the first question.

"Does she know what's going on, sir?" Eren asked.

"She has the basic idea of where she is and what's going on."

"Has she recognized anyone besides associating them as someone else?" Armin spoke up.

"Yes, she referred to Lieutenant Levi as "the strongest knight"."

There was a scattered response of amusement as Erwin stepped down after he heard her mutter, "Hungry, Daddy." He raised his hand.

"Any further questions will be answered after dinner."

He sat next to Hange, who had an extra serving of food after getting his own.

"Come on, Snow, time to eat." she cooed and took her from him.

Erwin sighed in relief. As cute as she was, it was starting to get a bit tiresome having to work around her because she didn't want to let him go.

Even as she was distracted with eating, the only person she talked to besides Erwin and Hange so far was Levi, she shied away from anyone else. Levi believed it was because she worked directly under him, so even if she didn't want to speak with him, she answered him anyway.

"Is it good, Snow?" Petra cooed, but pouted when she tried to hide her face into Hange. "How is that fair?"

"Snow. She asked you a question." Levi said.

"Mm." the toddler nodded. "Yummy."

Petra pouted further, some of her teammates chuckling.

"Who's this?" Levi asked Snow, pointing at Mike next to him.

"Sniff." she answered.

Mike leaned in and sniffed in her direction, which caused her to giggle. Mike cracked a smile. She was cute indeed. It seems that was enough for her to place him in her newly formed inner circle. After she was done eating, Erwin asked Levi if he could gather her friends for any further questions since he was sure she was going to put up a fuss if he left.

"Brats." Levi called as he neared the table. "Come now if you want to speak to her."

Her friends reacted immediately, rushing over to the table and half surrounding her. Her entire field of vision in front of her was suddenly and quickly taken up. She stared up at them curiously.

"Aw, she's so cute!"

"And so small!"

"Hey, she's not trying to hide. You think she recognizes us?"

"Hi, Snow!"

The babe cringed at the sudden loud voice and started to tear up.

"Oh no!"

"Conny!" a couple of voices scolded in unison.

"I'm sorry! I thought she would react like she usually did!"

"She's turned into a baby, you can't just shout in her face!"

"Much less expect her to respond positively."

"Idiot. Do you know nothing about children?"

"Snow, I'm sorry, OK? Please don't cry?"

She instead got worse, more tears welling up in her eyes and she let out a loose hiccup. She cuddled into Erwin's side and his eyebrow twitched, one of his hands coming up to rest on her back. It took seven seconds for one of them to make her cry. Not even Levi's rash actions made her cry. He's going to force every one of them away if any of those tears in her eyes falls.

A pleasant tune floated from Krista's lips, the rest of her friends recognizing it as a tune she used to hum when she was upset. She had once said it was something her mother used to do when she was young to help her calm down. Her mood seemed to calm the more she hummed and it got to the point where she was looking at her, her teary eyes quickly becoming a thing of the past. The babe sniffed as Krista stopped, now that her mood has improved enough that she was certain she wasn't going to cry.

"Oh! Good thinking, Krista!" Hange congratulated, a bit softer now to avoid making Snow upset again. The rest of her cadets friends followed her example.

"It was a tune she taught me. She used to hum it when she was upset."

"Pwetty humming, Angel." she spoke up and Krista blushed.

"Kyaa~ Her voice is so cute!" Sasha cooed.

"Wait. Is she going to be sleeping with you, Commander?" Jean questioned. She seemed very attached to him.

"No." Erwin answered quickly. "Hange will be sharing her quarters with her."

"I wonder if she'll let us hold her?"

"Would you mind, sir?"

Erwin quickly scooped her up and gently sat her on the table, finding it effective, as it seems she tended to cling when she didn't want to move. If he removed her quickly, however, she wouldn't have time to react and cling. She stared at her friends once again, locking eyes with Krista. She raised her hands at her, wishing for her to quickly pick her up. She would much rather be in somebody's arms with so many people staring at her. She cooed, beaming at her as she picked her up. She hugged her immediately, a habit she developed in her training years. She would always hug her friends, especially Jean or Eren, as it always seemed to get them to stop arguing with each other.

"Ooh, me next!" Sasha bounced in excitement and stood in front of Krista.

Snow took a moment to notice Sasha wanted a hug next, but when she did, she gladly let Sasha take her from Krista and she wasted no time in hugging her, too. Sasha proceeded to press her cheek into hers and move her face to nuzzle, but Snow whined in discomfort, uttering the first actual name since her transformation.

"Sasha~" she clearly whined.

It was something she's always had a problem with. Every time Sasha returned her hug, she had always nuzzled her face and she would always verbally protest.

"I can't help it, you're just so cute!" she said and tried to nuzzle again, but Snow pushed her face and tried to wiggled away.

"Noo!"

She were upset yet again and Erwin had a weird itching on his fingers to take her away. What was wrong with him?

"For Goddesses' sake, Sasha!" Eren snatched the babe out of Sasha's arms. "Can't you see she's uncomfortable?!"

"Eren~" Now was Sasha's turn to whine. She didn't want to let her go just yet.

Snow reached up and held Eren's cheeks so he would look at her.

"It's OK." she said. Well, if he was irritated before, he wasn't now.

A look of recollection flashed on her face and her eyes searched the rest of her friends until she locked eyes with Jean. She reached a hand out and flexed her tiny fingers at him, beckoning him over. When he did and leaned in so she could reach his face like she wanted, she put a hand on his cheek and kept another hand on one of Eren's. She took a moment to look between them.

"No fighting."

They slightly flushed. It was clear as day she were still looking out for them, even in this form.

"We're not fighting!" Jean said.

"Geez, Snow..." Eren said.

It amused her friends greatly, a couple of them chuckling at them. Suddenly, Snow whined, rubbing her eyes sleepily and that sent Erwin over the edge.

"That's enough." he commanded calmly, standing from his seat.

"Looks like it's someone's bedtime~" Hange sang, asking Eren to pass the toddler over.

Before Hange walked away with her, however, Mikasa reached over and stroked Snow's head, muttering a soft, "Sleep well."

She caught one of her fingers before she fully retreated her hand, giving it a little squeeze.

"Good night, 'Kasa."

An endearing nickname she gave her that Mikasa had grown to like. Snow was the only person to call her that and to hear her say it, even in this state, made her send her a caring smile. The rest of her friends sent her verbal good night's and sweet dreams and she waved as Hange walked out of mess hall, following behind Erwin.

"How long did you say she would stay in this form?" Erwin wanted to remind himself.

"I believe it should last about a week. Perhaps a little under."

That's a problem. That's far too long a time for his mental health when it comes to you.

When Hange started to part from Erwin, even in her drowsy state, the babe whined about being separated from Erwin. She's seriously not good for his mental health. As a Commander, she can't sleep beside him, it's not professional, but as a stand-in father...

He can't seriously be getting into this.

The tears in her eyes slid down her chubby cheeks and without a thought, Erwin plucked her from Hange's arms and cradled her to his chest, in which she buried her face into. For a moment, both he and Hange stood in awkward silence, unsure of what to do.

Hange was supposed to take her to her room, but he just took her.

And Erwin reacted without thinking. What was he supposed to do now?

"...I suppose, she can sleep with me tonight."

Hange inwardly snickered. Snow's tears was all it took?

What a doting father...
