A/N: Alright. This is my first Avengers fic. I haven't read the comics and I haven't even seen all of the marvel movies so I'm probably way under educated about this type of thing but I've really been wanting to make an OC after seeing Age of Ultron. My friend actually suggested that I make her Steve and Tony's daughter so this is also a totally new writing playground for me. If I get some fact wrong or something totally doesn't follow some storyline feel free to stop reading if you cant get past it but please don't point it out to me to be mean. I know there's a lot I don't know and I'm just writing this to fill an Avengers addiction. So have fun reading and hopefully I don't dissapoint everyone who tries to read it. Just bare with me and please review if you'd like.
Bruce Banner worked at his desk quietly. His eyes were focused intently at the equations and scenarios in front of him. Bruce normally preferred it to be quite while he worked, but with Tony Stark and Steve Rogers constantly arguing behind him, he figured he wouldn't be getting a quiet lab anytime soon. He was, after all, helping these two knuckle heads bring their daughter into the world.
"For the last time Tony, we should hyphenate her last name!" Steve crossed his arms. The two of them had been arguing over this for the past hour or so.
"I don't think so Cap." Tony made a face the definitely said 'I'm better than you'. "My lab, my equipment, my daughter. So she gets my name." Tony walked over to Bruce and bent down beside him, clearly signaling that he was done with this argument.
Bruce glanced sideways and sighed. "What is it Tony? This stuff takes time. You need to be patient." Tony was definitely the more nervous parent, which surprised Bruce to no end. Tony was constantly hovering over his work area while Steve normally just stood in the background with his arms crossed.
"Oh no, don't mind me Banner. Just checking on your progress." Tony grabbed up a few papers and studied them before throwing them back down and picking up different ones.
"Tony. Let the man do his job before you mess something up and harm our child." Steve came up behind Tony and wrapped his arms around his waist, resting his chin on Tony's shoulder. "She'll be here before you know it. Let Bruce do his job. Come on."
Tony hesitated slightly before nodding and allowing Steve to lead him away from the lab. Before they walked upstairs completely Tony stopped a moment to tell JARVIS to keep him updated. Steve couldn't stop the soft chuckle that bubbled up as he yanked Tony by the hand to get him to follow again.
