Completely taken aback Cassie turned to glance at Steve with a dumbfounded expression. "Are you serious?" she asked and inched away from Tony on the couch. Hadn't she just agreed to all the important parts of the deal? The outburst was totally out of left field and, yeah, that reminded her a lot of Peggy. She was having a really hard time controlling her temper now but under the look he gave her, she felt herself shrink a little.
"My ability is useful all the time," she insisted, trying to keep her voice calm and her expression neutral (instead of totally freaked out, which she was at the moment).
"If you haven't noticed I'm pretty short, I grow all the time to reach things on high shelves and shrinking is useful sometimes, too. Cap doesn't need super strength and you don't need whatever the heck weird techno stuff you do, but you still use it, don't you? I'm giving my word that I won't sneak out and that I won't go fighting crime without you guys to supervise me, that should be enough."
