"Twenty," she said with a half-smile, but only when she for sure knew Tony wanted an answer this time. Kate didn't know where he was even going with that, but she didn't have the energy to put him back on track, she figured they'd get around to it eventually--she wasn't busy. At least Tony put some effort into guessing her age right. "But, I'm pretty sure Barton thinks I'm twelve." Somewhere around there, which was obviously ridiculous, but she'd long ago decided that Clint was kind of a doofus. Kate made a face and smiled, holding her hand out to Tony as if hoping he would know why this might be, but eventually shrugged; it had to have been in good fun, Kate did like to throw the "old man" card at him (mostly in retaliation) on occasion.
