A/N: Obvious Cap angst because I cannot fucking control myself right now.
"Olivia, I expect you to be on your best behavior. And leave Cap alone, would you? The man is in his eighties. He can't handle it," Nina bit her lip to keep the smile off her face.
"You," He pointed at Katerina. "Lay off the candy," Katerina's jaw tightened and the space they were in suddenly seemed hotter and more claustrophobic.
"New kid," Nina perked up. "Stick with the adults,"
"We're all adults, dad," Olivia reminded him.
"The real adults," Tony clarified. He gave the girls a tight smile before leaving the cabin.
The jet landed on top of the Tower only a few minutes later and the four of them made their way into the building. Regardless of how much she'd been thinking about it, Nina didn't feel at all prepared for this moment. She followed at the back, focusing mostly on keeping her heart rate under control. All that hard work was undone the second they walked into the main Avengers living quarters.
The scene was a relaxed one. Steve and Bucky were on the couch watching a documentary and Wanda and Pietro were at the kitchen island eating lunch.
"Welcome back," Steve turned to greet Tony, forgetting he was bringing anyone new with him until he saw her. Nina didn't know where to look. Her feet were the preferred option at this point, but that wasn't very professional.
Olivia and Katerina wandered off talk with Wanda and Pietro, leaving Nina alone with Tony when Steve reached them.
"Hi," Just looking at his eyes was enough to make Nina want to fall over and his smile didn't do anything to stabilize her. "I'm Steve Rodgers," He held his hand out to her. Luckily, despite completely falling apart inside, Nina managed to act like a functioning human being.
"Nina Wesley" She smiled at him and took his hand. His grip was firm and strong, whereas hers was gentle and lacked conviction. Steve had only just met her and already he was worried for her safety.
"It's good to meet you. Tony tells me you're a healer," Nina withdrew her hand and clutched it in her other, fiddling nervously.
"Yes," She nodded.
"That's good. You could be a great asset to the team," Nina was about to respond before being interrupted by Olivia from across the room.
"Or just a great ass, am I right?" She called, eyebrows wriggling. It was safe to say by now that she would flirt with anything that breathed.
Steve threw her a disapproving look over his shoulder and Olivia shrugged.
"I'm just sayin', Cap," She popped something into her mouth, never breaking eye contact with him. Tony sighed heavily and took this awkward moment as his chance to leave.
"I'm sorry. She..." Nina tried to make an excuse for Olivia being obnoxious, but there really wasn't one.
"I know," Steve turned his attention back to her, giving her a half smile.
"So, I'm told the girls stumbled across you at a gala," He was quick to move on and relieve any awkwardness.
"Yeah," Nina answered, also relieved. "It's been a long couple of days. I was expecting to be back home wasting my summer by now," Until a few days ago Nina's plan for the summer had been to catch up on reading, take a lot of naps, and make as much money as possible while she had time. She was pretty sure none of those things were going to happen.
"Where's home?" Steve asked.
Nina smiled, knowingly. "Brooklyn,"
Steve went on to ask her about her family and her schooling. They were easy questions, which she gladly answered. She was just starting to feel comfortable when Olivia came over to ruin it.
"Boring," Olivia sang as she grabbed Nina's arm and started pulling her away. "Come hang out with the cool kids," Nina gave Steve an apologetic look. He looked like he understood.
