Summary: Both Natsha and Steve have to leave for a mission, leaving their 3 year old daughter home alone with her auntie Yelena. Was that a good idea... probably not.

,,Okay слабый свет (little light), we're leaving now. Be good for auntie Yelena"

Natasha sighed, bending down to her daughter, who was playing on the floor.

Alena had grown... a lot. The sweet baby wasn't a baby anymore. She was now 3 years old. Her back length red hair tied into a French braid. The blue eyes brighter than ever.

,,Where are you going, Mama"

The little girl inquired, the big blue eyes beaming up at her mother.

,,любовь (love), your daddy and I need to go on a mission. Auntie Yelena is taking care of you, don't worry. We'll be back later, I promise"

The assasin explained. She stroked Alenas hair in attempt to keep her calm.

,,I don't want you to go"

The 3 year old whined, clutching her arms around Natashas neck.

,,I'm sorry, слабый свет, but this is our job. Look, when Daddy and I are back, we will have a day all to ourselves. We'll go have Ice cream, play with you until you can't stand it anymore and be with you all day long"

Natasha negotiated. They had to board the quinjet in mere minutes.

,,Nat, hurry up"

Steve's voice rang through the compound.

Alena let her mother go. She was now searching for her fathers voice.

,,Daddy?"

She called out.

Next things she knew, Alena was hanging mid air.

,,Bye honey, Mommy and I really need to leave now. Be good for your auntie"

He explained, smothering his daughter in kisses all over her small face.

,,Bye Daddy. Fly save"

The three year old muttered, while hiding her face in the crook of his neck.

Steve put Alena down. The little girl immediately took off running again. She needed to find her Mama to tell her goodbye after all.

,,Mama, don't leave yet"

She screamed as loud as her little girl lungs could.

Natasha crept up on her from behind, before finally trapping her in her arms.

,,Goodbye моя любовь (my love). See you tomorrow"

She sighed, hugging Alena tightly.

,,Bye Mama. I love you to the moon and back"

The three year old muttered into her mothers shoulder.

,,I love you too, мой маленький свет"

Natasha muttered back, before placing Alena into Yelenas arms.

,,Don't teach her anything stupid while we're gone"

The assasin ordered, looking at her sister sternly.

,,Yea yea, Natasha. You're such a mom"

Yelena teased, a smirk lingering on her face.

,,Yelena, I mean it. I don't want my daughter running around screaming bad words when I get back"

The redhead warned, a grin playing around her lips.

,,Hey, I'm the cool aunt. And as such it is my duty to spoil her a bit, isn't it Alena любовь (love)"

Yelena smirked before motioning her sister to leave.

Natasha turned around to leave.

,,Kids"

She muttered on her way out.

,,Bye Mama, auntie Lena is taking care of meee"

Alena shouted after her mom, waving frantically.

...

,,Okay Alena, what do you want to do?"

Yelena asked as she placed her niece on the ground.

,,I wanna ... I wanna buit a Fort"

The three-year old exclaimed, throwing her hands up in excitement.

,,Alright, let's build a Fort. What do we need?"

Yelena agreed, matching Alenas excited energy.

Alena got visibly excited. When everyone was home, she didn't have access to as many pillows and blankets as she had now.

,,We need a looooot of pillows and blankets too"

She dragged out, letting herself fall into her aunt.

,,A lot of pillows huh, where from, слабый свет (little light)?"

Yelena asked, amused by Alenas excitement.

The three-year old thought for a minute, then she exclaimed:

,,Mamas and Daddy's room. And uncle Tony's and Auntie Wandas and uncle Bruce's rooms. My Mama has a lot of pillows"

,, Alright then, слабый свет (little light), let's steal the pillows"

Yelena laughed. She took her niece by the hand as Alena took off running up to the bedrooms.

,,Okay auntie Lena, you can look in this room and I will go to Mamas room"

Alena explained, her eyes radiating excitement and joy. Yelena smiled at the little girl fondly.

,,Got it, boss"

She smiled. Alena vanished in her parents room.

The three-year old jumped on her parents bed, throwing the majority of the pillows on the ground.

This alone tired her out a lot, so much to the point where she struggled to keep her big blue eyes open.

,,I miss you, Mama"

Alena muttered as she smelled her mothers perfume on the sheets.

Yelena walked in on Alena, curled up in a ball with the white blanket pulled over herself.

The sight made her heart melt. The little girl reminded her so much of her sister. Apart from the blue eyes, Alena could be her mothers twin.

The blonde crept over to the bed, gently taking the three-year old into her arms.

,,Are you alright, слабый свет (little light)?"

She asked softly, cradling her niece in her arms.

,,I miss my Mama and my Daddy too"

Alena admitted, her voice muffled by the fabric of her aunts shirt.

,,I know, I know. But I know what will cheer you up"

Yelena soothed, a smile creeping onto her face.

The three-year old redhead looked at her.

,,What, Auntie Lena?"

She asked curiously, all signs of sleepiness gone.

Her aunt grinned, before she suggested:

,,Let's make a cake, shall we?"

Alenas eyes lit up. She flung her little arms around Yelenas neck in excitement.

,,Let's make a cake auntie Lena!"

She exclaimed loudly, all her energy coming back.

,,Let's bake a cake, слабый свет (little light)"

Yelena smiled, before the two of them abandoned the mess Alena had made to go to the kitchen.

...

Alena sat in her high chair, next to her Yelena, desperately trying to fish an eggshell out of the cake batter they had made.

,,дерьмо, who said baking a cake was easy"

Yelena swore. The eggshell was frustrating her greatly.

Until she heard her niece say:

,,дерьмо (shit)"

Alena was beaming at the extension of her vocabulary, but Yelena wasn't so amused about it.

,,Ohh, no no no no, Nats gonna kill me. Hey Alena, we don't say that word"

The blonde freaked out, trying to get the word out of Alenas head.

,,What word? дерьмо (Shit)?"

,,Exactly that. Do you even know what that means?"

Yelena inquired, hoping she didn't.

Alenas beam got wider. Of course she knew what it meant. She had asked her uncle Tony, who had then googled it for her. When asked where she got it from, she said she heard her Mama use it all the time when she thought she wasn't around.

,,It means Shit"

Alena proudly explained, her little arms crossed over her stomach.

Yelena was panicking now.

,,Alena, listen to me carefully. You can never say that word in front of your Mama, Okay. Not in Russian and not in English. Its our secret word, Okay?"

She tried teaching the little girl.

,,Can I say it in front of daddy?"

Alena asked, her head turned to the side slightly.

,,No, слабый свет (little light). Promise me you won't say it ... ever, Okay?"

Her aunt sighed, holding out her pinky finger.

The three-year old frowned, but locked pinkies with Yelena.

,,Auntie Lena, I think our cookies are burning"

She then informed the blonde.

,,Ahhh, thanks little light. Shit shit shit shit, your mother is going to cook me alive when she finds out I burned the compound down"

Yelena swore. She was too focused on the cookies, which were smoking violently in the oven, to notice Alena giggling behind her.

A few moments later, the cookies had stopped smoking, after Yelena pulled them out of the oven.

,,Not a word to your parents about this"

She warned, pointing her finger straight at the little redhead.

Alena just giggled innocently.

...

,,We're home"

The voice of Tony Stark rang through the compound. Yelena and Alena sat on the couch, watching frozen.

He came into the living room, followed by Bruce Banner, Wanda Maximoff, Clint Barton Thor and of course Alenas parents.

,,You're back, Mama you're back"

Alena cried as soon as she saw her mothers red hair appear in the doorframe.

,,Alena, мой маленький свет (my little light). Did you have a nice day with Yelena?"

The assasin asked as she picked her daughter up.

,,We played and we almost burned the house down"

Alena listed proudly, her eyes growing with joy.

Natasha looked at her sister sternly.

,,Snitch. I swear we didn't do anything stupid. We were making cake and cookies and the cookies mightve burned"

Yelena defended herself, her hands thrown into the air.

Natasha glared at her with the infamous Natasha Romanoff expression.

Alena squirmed in her mothers arms, reaching over to her dad.

Natasha handed her over to Steve safely, before she made a step towards Yelena.

,,Shit"

Alena exclaimed loudly.

Everyone was frozen. Tony stiffled his laugh, Wandas mouth was open, turned to the little girl, Clint put a hand to his mouth to contain his laughter, Bruce was unsure on what to do or say, Yelena had pure panic in her eyes, Steve's eyes doubled in size, Thor was close to loosing his shit and Natasha, Natasha was ready to murder her sister that day.

,,You're never taking care of her again"

The assasin informed her sister, trying hard to hide her smile.

,,No, Natasha I only said it in Russian. I didn't know she knew what it-"

Yelena tried explaining, but what cut off by Alena singing to herself:

,,Shit, Shit, shittt"

Everone in the compound erupted in laughter and even Natasha smirked.
