The disappointment that flashed across Cassie's face was obvious and when she answered Tony it was with something near to suspicion in her tone. "Well, I guess, I just- you know, I could drive a car anytime. I don't get many chances to go out with you two. Iron Man and Captain America, I mean." She looked to Steve now and then turned back to look at the car.
She didn't want to hurt Tony's feelings or something but she also didn't want to be deprived of the opportunity to feel like an actual Avenger fighting crime with actual Avengers. "We can drive for a bit but then we can go find someone to punch?" she asked, hopeful, a compromise, and she moved towards the car to show her willingness to acquiesce to Tony's suggestion so long as they were willing to follow through on hers.
