Underground

Steve walked to Tony and crossed his arms “Stark what the hell was that?”
“Language”
Everyone turned to Sherazaad.
“Jesus, I was just trying to enlighten the mood” she mumbled. She joined Loki who was sitting on something that looked like a piece of the table. She patted their back.
“Liked the party?”
They looked at her and chuckled “Well that was very fun, but I have to go back to Asgard. Good luck with the mad robot.”
“I didn’t forget our bet Laufeyson.” Loki smirked at her before grabbing her hand and kissing it. “Neither did I. Don’t die.” Loki disappeared in a green smoke.
Sherazaad went back to the Avengers who were drowning Tony with questions, but he stayed silent. Bruce gave in and explained what him and Tony had been doing in the lab before the party. And that they needed the scepter to achieve their goal.
“Look it wasn’t supposed to work-“ Tony stated before being cut off by Steve.
“Well, it obviously didn’t. You have to do something to fix that.”
“The thing is I don’t know how Rogers.” Tony said dazedly and Steve sighed.
“You better find a way because all of this is your fault !” Clint looked like he was about to cut Tony’s throat.
"This is not just one person’s fault. This is on all of us. We are a team." Steve looked at Clint. "Teams have to stick together, that means what one of us did, we all did. That also means that we ALL have to fix this and I swear to God if I have to hear you two bickering the entire time I’ll knock you out. Do I make myself clear?"
Everyone nodded.
"They took the scepter, we need to figure out where they went and why they wanted
it."
“That may be hard. He’s in our files, he’s in the bank records, he’s everywhere Shera.” Tony declared, looking at the computers.
“So he know more about us than we know about each other” Nat sat on the counter.
Sherazaad suddenly remembered the blue stream. “What about the dickhead in Sokovia ? Strucker ? He had to have some idea of what the scepter was able to create”
“Well he created two enhanced not a moving, talking Google”
“Google exactly. You lot come with me.” They all followed Natasha into the archives room. They began pulling out files from years ago.
Bruce suddenly stood up and rushed to the computer.
“Bruce, what’s wrong?” Nat looked up from her box.
Sherazaad read what was on the screen and her eyes widened.
"Wakanda"

“Aw junior. You’re breaking your old man’s heart”
Sherazaad was hidden like Clint and Natasha. She could see and hear everything. Her orders were to watch them and take out any of Klaus’s henchmen, but not the twins themselves.
“So, I see Thor, Captain America and you, but there are some missing correct? I figure you've hidden Dr. Banner away, but what about the ex-KGB, the bowman and... Oh yes, the enhanced teenager."
Ultron looked around but quickly looked back at Tony to continue their conversation.
Sherazaad checked her watch, how long this family reunion was going to take ? When she looked up, she faced a red-eyed robot.
“I found you…” it said, with the same creepy voice Ultron had at the party. The robot’s eyes turned back blue and it shoot her. She barely had the time to create an energy shield.
The Avengers, Ultron’s bots and Klaus’s henchmen, all started to fight.
She punched a right-hand man and kicked him in the legs before shooting him between his eyes.
“Could have just used your purple stuff on him.”
She swiftly turned around and pointed her gun at her orator. The fast twin.
“Maximoff.”
A smug smile was painted on his arrogant face. Cheeky bastard.
“I’m not moving for once, you could have shot me. Why aren’t you fighting me солнышко?” He started walking closer but stopped when he saw she didn’t lowered her gun. She didn’t shot him because Steve gave her the order to not hurt the twins. Also because she hoped she could help them coming to the good side.
“Why are you not fighting me Maximoff?”
“Я не дерусь с красотками.” He grinned proudly, probably thinking she couldn’t understand.
“Ты правда считаешь меня красивой ?” Watching Netflix series in Russian with Natasha finally paid off.
The last thing she saw was Pietro’s surprised face. Everything went black. Her head was hurting.
When she opened her eyes, she instantly recognized the door in front of her. She pushed it and entered her old room. Posters everywhere, her bed was messy and there were clothes all over the floor. Her father didn’t liked the posters but she didn’t care. She took her Black Widow plushie and smiled, Natasha always has been her favorite.
“We did it? We’re an Avenger?”
Sherazaad smiled warmly at her younger self standing in front of her.
“Yes we are. And we’re very friend with all of them.”
“Then why did you let them die?”
Sherazaad’s heart sank. Die ?
“I didn’t- They’re alive…All of them!”
She blinked and her younger self disappeared. Along with her room. She was standing in a forest. She saw some of her friends and ran to them. She tried to hug Steve but he turned into dust. Everyone was turning into dust.
“STEVE! TONY! GUYS WHAT IS HAPPENING?”
She ran around trying to find her friends, in vain.
“BRUCE? THOR? HELLO ??”
Her head was a mess. She kept hearing loud whispers saying nonsenses.
“NATASHA?” The second that name escaped her lips, she was somewhere else. This place was beautiful but something felt off…She was on top of a cliff and the sky was purple and blue-ish.
“I love you Sherazaad.”
She turned to see Natasha smiling at her sadly before running to the precipice. Sherazaad tried to stop her with energy shields but her powers weren’t working. She ran after Natasha and jumped with her. She grabbed the edge of the cliff with one hand and Nat’s hand with the others. Her vision was blurred by all the tears.
“Nat…Natasha please, I only have you left. Stay with me I’m begging you.”
“I have to моя дочь. Let me go…It’s okay.”
Sherazaad was crying uncontrollably.
She knew pain. She was in pain when her powers would go off, when she would step on her brother’s Legos, when her father would hit her, when she was stabbed, shot or beaten on missions. When her heart would be broken again and again by people she loved with her whole soul. When she would hear comments about her as a female superhero of color.
But nothing prepared her for the pain, the suffering, she would feel as she watched Natasha Romanov letting go of her hand and fall. She was falling to her death and Sherazaad was powerless. Useless.
She climbed back to the top and tried to stand up. But she fell on her knees, drowning in her tears. She screamed on top of her lungs. She felt like her heart has been ripped off her chest. Natasha…her teammate, her best friend, her mother.
“Мне жаль, мама.”

Sherazaad blinked several times. She wasn't on that cliff anymore.
Just some centimeters away from her face, two electric blue eyes where gazing at her. She wanted to hug the owner of those mesmerizing eyes, she didn’t gave a fuck about who it was; she just needed comfort after losing Nat. Suddenly, she realized the vision of Natasha falling was just that, a vision. The Maximoff girl. So that what Maria meant by “She’s weird”.
The silver haired boy grinned cheekily at Sherazaad.
“Like what you see?” he said in a soft voice with his strong accent. She realized she was probably staring at him the whole time she was lost in her thoughts.
He was holding her hand and she could feel her heart throb. The whole situation was awkward. Did he saw her cry? Has he heard her scream in grief?
“Sherazaad!”
She turned her head and saw Steve with a weird look on his face.
“Get away from her kid, I don’t want to hurt you.”
The speedster stood up and she felt the warmness of his hand leaving hers.
“That’s my cue to leave. Captain.” He nodded in Steve direction. He then turned his eyes towards Sherazaad and she felt something strange in her chest. Like it was burning but in a good way? Wow that little red bitch really messed up with her. “See ya принцесса.”
One second later, he was no longer here. Steve helped her to stand up and carried her bridal style. “I can walk Rogers.”
He sat her in the Quinjet and every was here in the same state she was. Everyone except Tony, Bruce and…Natasha. Her heart stopped as well as her breathing.
“Steve where’s Nat? Where is she?”
“I’m right here darling.”
Natasha entered the Quinjet, helped by Clint. Sherazaad squeezed her in her arms and a tear rolled on her cheek.
