I had this really weird idea now that Loki is a good guy. This honestly doesn't affect the story whatsoever. Just know Tony is her dad, Steve is an "uncle", Loki is a good guy and Peter is her boyfriend.

And I may extend this imagine sometimes ;)

-

"Sometimes I wish I could have raised Bea, so she wasn't so apprehensive around me." Tony confesses to Steve. In return, Steve nods.

"I think she'd be a nice little kid. Pretty strong for her age, you know?"

"What if I was able to give you what you wish?" They hear Loki say, slinking into the room without a sound.

"You could do that?"
"No way."

Tony and Steve looks at each other, puzzled by each other's answer.

"It wouldn't be permanent. Five or six hours at the most."

"Would it hurt her?" Tony asks

"No. She'd simply be deaged and powerless. Exactly her mindset whenever she was that age. Of course, with the knowledge you are her Guardian." Loki explains.

"Do it." Tony says firmly.

"Wait," Steve interjects, "First of all, this would be infringing on her decisions? Second, what if he's lying?"

"Now why would I lie to you?" Loki taunts

"Because you are the god of lies!" Steve exclaims.

"Then it may anger you to know-"

"Mr Stark, you may want to come here." they hear Peter say over the intercom.

-

"So how old is she?" Steve asks

She raises up her hand with five fingers. Peter then walks over with a smile.

"Hey, Bea. How you feeling?" he asks

"I'm okay. My throat hurts a little but I'm okay." she insists. Tony gives Peter an odd look.

"Why does her throat hurt, exactly?" he asks.

"When Bea was little she had really bad asthma, weak immune system. The works." Peter explains, "To be honest it's probably not just her throat. Her parents didn't really care that much if she got her medication. Leaving her sicker than any normal kid with her problems."

"That sounds like me when I was younger... minus the lack of meds." Steve says, "Hey, sweetie, it's okay to tell us where all it hurts, okay?"

"My eyes are itchy too. And I'm really tired." she admits.

"Well then, we'll let you take a nap." Tony says bluntly

"You wanted this, yet you're not very good at it." Loki says, appearing in the room next to Bea.

"Mr Loki." she says, a little quieter. He pats her head affectionately and looks at the three other men.

"Stark wanted to raise Bea from childhood, so I gave you this chance." he addresses, "Yet it appears the other two know better."

He steps a few feet forward and looks down at Tony.

"Since I'm a better person these days, I won't make them disappear. Instead, I simply ask that you allow Stark to keep his word."

"What?" they all ask in unison

"You two cannot help him take care of her. If you do, I'll up her time by an hour." he instructs, "I'll give you these."

Loki hands Tony a bottle of small white pills.

"What are these?"

"These are pills to treat her asthma side effects. They wear off in two hours." Loki says, "I should warn you, though. Children are not as easy as they appear."

And with that, Loki was gone. Tony looked to Peter and Steve.

"Good luck, Mr Stark. Please be gentle with her? If Loki replaced her mind when she was five, that means that her dad and brother have already abused her."

Tony looked to Bea, who was beginning to drift off in her large sized bed for a five year old.

I guess she's always been small, Tony thought.

"Hey, kiddo, you ready for a nap?"

"No. No, I'm fine." she whined, "Imma big girl! I don't need naps!"

As she threw up her arms it suddenly became apparent that Bea no longer fit into her older form's clothing. The collar of her shirt fell down below her chest area.

Tony slapped a hand over his eyes.

There's nothing there anymore, nonetheless it felt like some sort of moral wrong to look at his de-aged, adoptive daughter, and best friend, who he respected the privacy of immensely.

"Be right back," he exited the room and composed himself, "Loki."

The trickster appeared in front of his summoner with a curious glance.

"She's not asleep... What do you need me for?"

"Fitting clothes." he says bluntly, "I can't have a naked five year old girl running around my building."

"Does nudity offend you?"

"Yes! Nudity offends me!" Tony seethes, "Now clothing."

"Fine."

Loki waved his hand and some small articles of clothing appeared.

"I tried to tailor to your appreciation." Loki says

"This being nice thing is really taking a toll on you."

"Extremely."

He disappeared again and Tony reentered the room. A small ACDC t-shirt and black legging-tights sort of things.

"I can't dress you, so... Here." he shoved the clothing forward and Bea grabbed it gently.

"I can get dressed."

Tony exited while she put on her new clothes. Peter then walked by.

"What are you doing, Mr Stark?"

"Allowing her to change."

The door opened revealing a small little Bea, retreating the room, dressed nicely.

"Mr Tony can you do my hair?" she requests.

"I-I can't do hair." he dismisses.

"You don't know how to braid?" Peter asks

"You can't either, so shut up."

"Actually I can, but if I help you, Loki will add another hour. And also, she specifically asked for you."

"Look, I don't care who does I just want my stupid hair out of my face." she complains.

"Little Bea is just as annoying and sassy as older Bea." Tony mumbles.

"Of course. I'd expect nothing less from her." Peter says, "I can show you how, but I'll need a doll or something."

"Hold on." Bea says, running back into her room and collecting a doll.

"Where'd you get that?" Tony asks, while Peter just starts busting up laughing. "What's so funny?"

"Bea collects Barbie's still, that's hilarious!"

"Still?"

"She hated playing with them, but collected them and hid them from everyone. It helped no one could go in her house."

"How did you know?"

"I'm her best friend, she told me."

Bea handed Peter the doll then grabbed Tony's large hand in her tiny, rather delicate one, and dragged him to the common room.

Peter adjusts the Barbie between his jean-covered legs and begins to teach Tony how to braid hair, Tony practicing on Bea.

After about ten minutes, Tony successfully braided the temporary five year old's long brown hair. Silently admitting to himself how unbelievably soft and delicate it felt in his hands.

"Thank you, Peter." Tony says, giving him a genuine smile.

"You're welcome Mr Stark."

"Where did you learn how to do that?"

"Well look at that, Aunt May just texted me saying I have to be home ASAP-"

"I know for a fact that didn't happen because you are literally staying here for the week since she's out of town."

"I grew up with a girl. She taught me how because her parents never did it for her. She wanted to have braided hair and so she taught me so I could do it for her. I've just kept the skill around in case."

"That's oddly nice of you." Tony says.

"Thanks."

Tony had successfully put Bea to bed about thirty minutes ago. He was now in his lab doing random things to tinker on his suits.

"Mr Tony?" a soft voice, Bea, asks from the door. She was so quiet. She sniffed and coughed, and rubbed her eyes. She looked awful for the medicine wearing off ten minutes ago.

"Oh, kid. Come on." Tony lifted her up and brought her to the kitchen. He sat her on the counter as he got a glass of water and one of her pills Loki gave him for her.

He handed her a pill and the glass. She wrinkled her nose at the pill.

"I'm not taking that." she stated flatly.

"You have to."

"No."

"You have to."

"And I say no!" she pouts, crossing her arms over her chest, squeezing her eyes shut

"Pretty please?" he asks, "I'll get you an ice cream after your nap?"

"Chocolate marshmallow?" she asks, opening one of her eyes.

Tony nods, giving into the little girl's wishes. Bea takes the small white pill and pops it into her mouth, downing it with the water.

After a few minutes her eyes looked better and she wasn't sniffing as much.

Tony lifted her up and brought her to her room, laying her down and covering her in her blue blanket. She was swimming in the large bed, but didn't seem to mind all that much. She honestly over enjoyed it.

She curled up in a ball and closed eyes.

"I'll come check on you in half an hour, kiddo."

"Okay, Mr Tony." she agrees, yawning softly. Tony gave her a small smile and left the room, dimming her lights halfway.

"You took care of asthma easily." Steve states, making Tony jump.

"Don't sneak up on me!" he whisper shouts quickly.

"Sorry. Didn't mean to scare you." Steve walks beside him as they enter the elevator to go to his lab. "She seems to take a liking to you. And she doesn't seem affected by the abusive memories."

"Of course she doesn't. I removed them from her younger mind." Loki says, appearing beside them.

"Again with the sneaking up on people! Stop it!" Tony says, "Or I swear I'll put bells on all of you!"

"All I'm saying is that the younger Bea has no recollection of anyone abusing her. As far as she knows, you are her biological father. She's too young to know about any mother figure ever being in her life," Loki explains, ignoring Tony's bell comment. "Though fond memories of Miss Potts replaces any motherly figure."

"Bea will know I'm not her actual father when she becomes normal again, right?"

"Well of course. I just didn't want young Bea to not trust anyone but that boy, Peter?" Loki asks. Tony gives him a nod, "This was your wish after all. And Peter is the constant in her life. Something unchanging."

"Fair point. So I guess I should say thank you."

"You are most welcome, Stark." Loki disappears.

-

After five hours and fifty nine minutes, Tony sits in the common room, Bea on his lap in one of her t-shirts and an oversized pair of elastic banded shorts that were safety pinned in the back. She had her head in his lap, asleep. Tony was no more awake than she was. Credits rolled on the TV from the movie they were watching.

The minute passed and Bea returned to normal size, still sleep on her adoptive father's lap. Tony wakes to see her, full-sized yet calm. Relaxed and back to her fifteen year old body. He sighs in relief.

Peter walks in to see them.

"She's grown." he comments.

"Yeah. I have to admit, that was fun."

"She's always hated little kids with a passion. Refutes she ever was one."

"We've seen it with our own eyes. She's interesting."

"Very."
