Tony stopped his work and looked at Clint, "You do know you are talking about Natasha Romanoff... right?" He shook his head, "As her partner, I think you would be the one to know you don't have anything to worry about. Unlike you, she didn't have explosive arrows fighting those aliens and I think she did fine," He started to work on the arm for a moment before he stopped once more, "Wait," He leaned back in his chair and glanced at Clint, "I thought you said you weren't stupid," He chuckled a little, "Screwdriver, there" He pointed to the elbow joint, "Righty tighty."
