Clint reached her first, and to his relief he saw four tiny fingertips, straining to grip the edge of the building. Lying down, he gripped her other hand and slowly began to pull her back up as best he could. As Steve reached them her grip of the rooftop gave out and it was only Clint preventing her from falling. He slid forward as he held up Natasha's added weight, and Steve grabbed him just as he began slipping.
Tony was finally given the opportunity he'd been waiting for to punch Agent Sitwell in the face.
Steve dragged Clint back and lifted Natasha back onto solid ground as Tony rushed over and helped the three of them back to their feet; Steve looked relieved, Clint looked scared and Natasha looked outright terrified; she flinched away from him when he went to help her and she quickly re schooled her featured into a mask of indifference.
"Nice reflexes" Steve told Clint, clapping him on the shoulder and earning himself a grateful smile for the compliment.
"You okay kiddo?" Tony asked Natasha, noticing her stoic expression and silence.
"Y-you didn't let me fall" she stated, confused.
"Of course not, that's like a 300 foot drop!" Tony told her, peering over the edge of shield HQ down to the sidewalk below and shivering at the thought
"B-but it was my fault... You s-should have let me fall"
"Did you want to fall?" Clint asked, a little taken aback by her reaction.
"No" she whispered
"Then why would you think that?"
"They would have let me fall..."
Tony and Steve glanced at each other and decided it was time to get back inside and end this conversation
"Do you trust us now?" Steve asked, positioning himself between the children and the edge of the roof
Clint agreed hastily, a grin on his face; the kid clearly looked up to him and that made Tony smirk. Natasha nodded slightly, avoiding eye contact with the others and crossing her arms over her chest to try and stop shaking. If Tony didn't know Natasha better, he'd have sworn she was blushing...
"I'm sorry" she whispered, before trailing slowly after the others as they made their way back inside.
