AN: So I got this idea awhile ago. What if Elijah had a daughter with the Black Widow from the Avengers. What kind of life would she have being the daughter of two of the deadliest people in the world. It will mostly take place during the Vampire Diaries and the end of the Avengers.

17 Years earlier…

The bare forms of a couple lay in the large bed, the man's arm draped over the round belly of the woman he loved, holding her close and he pulled the blanket up around her. Beneath his hand, the tiny being kicked, making him smile.

"Peace little one, your mother needs her rest." He smiled, making the babe stop.

Natasha smiled as she felt Elijah's hand on her skin as the baby resumed her kicking. He chuckled, realising she was playing with him.

"She's playing." Natasha said, making him nod. "I see that...she likes my voice." Elijah smiled. "She's going to be a daddy's girl." She yawned, pulling his arm closer.

Elijah smiled to himself at the thought of having a little girl calling him daddy. He made a promise to himself that he would never abandon her or leave her unprotected. Natasha saw the almost goofy grin on his face through the mirror and smiled.

Three months later, Evangeline Rayne Mikaelson was born. She made her debut on a stormy night in New York City. Natasha had a hard labor, both tearing and bleeding heavily. Elijah remained by her side, refusing to leave her alone.

When Clint and Coulson arrived to check on her, she smiled as Elijah held her by the window. With each lightning flash, the babe stared into his eyes as he told her the story of Thor and Loki.

"He is smitten." Coulson smiled, making her nod. "He is, I'm glad too, makes me feel better if I have to leave her alone with him." She yawned.

"How are you feeling?" Clint asked, producing a bottle of her favorite soda and a burger. "You are a saint." She breathed, making Elijah smile as the babe yawned. "I try...hey, Elijah, you going to share?" He teased, making him look up.

"I supposed I have to share you with your Uncle Clint, but not for long." Elijah told the babe, who was sound asleep.

"You're going to be fun when she's dating." Coulson teased. "I will be fine...Niklaus will be here in the morning...he wants to see her as well." Elijah smiled, making Natasha nod. "That is fine...she needs both her uncles in her life." She smiled.

Late that evening, Elijah held Evangeline, humming to her softly in French. The nurses had been compelled to let her stay with them, the ancient vampire not wanting her out of his sight.

"Je t'aime ma belle Evangeline." Elijah smiled.

Now…

"Please be careful, mama...I don't want you getting hurt." The voice of a teenage girl asked. "I will sweetie, when is your flight?" She asked. "The morning...I wanted to get to the dior boutique and get some sunglasses. Daddy left some money for me." Evangeline smiled. "Alright...as long as the world doesn't go to hell, I'll see you at the airport in the morning." Natasha smiled as Steve walked over. "Okay, je t'aime maman." Evangeline smiled. "I love you more, ma belle Evangeline." She replied before hanging up.

She turned to see him watching her as she hung up. He had a curious look on his face as she put her phone in her pocket.

"Was I interrupting?" He asked. "No, it was just my daughter...she's in the city and letting me know she is heading to her father's house." Natasha told him. "How old is she?" He asked. "16 almost 17...my ex lives in Northern Virginia, she's at his brownstone on the upper west side." Natasha told him. "Ah...does she know about all this?" He asked. "She does and hates when I have to leave...especially when I was undercover with Stark...I had missed her sweet 16." Natasha told Steve.

They walked back to the bridge, having to see what Fury wanted. When they did, the others saw her anxious face before she turned to Coulson.

"Can you make sure that Elijah knows Evangeline is heading his way or at least Klaus...I know how much of a prick he's been this summer." Natasha said. "Of course...he's currently in Chicago...that was after an entire sub pack died when he tried to turn them." He said, making her groan. "Great." She sighed.

Natasha knew her life was about to get a lot more chaotic with the hours to come. She just prayed that her daughter was safe and that no harm would come to her.

AN: Hope you like the story so far. This takes place during the Avengers and season three of the vampire diaries. It will mostly be in Mystic Falls but there will be appearances of the other avengers in the story. Please review and tell me what you thing.
