The laugh Steve had elicited died quickly on Tony's lips at the announcement of their audience, and he cleared his throat to swallow it and passed a hand over his mouth, innocently returning to his cooling coffee. How long had she been there? Tony finally took his life-affirming sip, cautiously peering over the edge of his mug at Cassie while she wasn't looking, and it occurred to him that despite how hilariously and desperately awful Steve made it sound a fraction of a second before, hearing Cassie denounce the scruffy motorcycle riders was suddenly a personal offense. If she had to go out with anyone-- well, the last person Tony wanted to get their hands on her was someone like him, he supposed that was probably a good thing.
More immediately, Cassie looked like she was running away now, if just for a day trip, instead of in a hypothetical girls' school future. As she collected the bottle, Tony slowly lowered his mug, forgetting her question and staring owlishly at her. She didn't tell him she had plans. Steve had him clear his schedule, they were both ready for this day and were going to...do whatever Steve had planned, Tony had lost interest by that point in the e-mails. Did she already have a date? She could bring him over. Tony would love to meet him. He'd make sure she never saw the guy again.
