Tony wasn't sure how to take that but with a breath and a sidelong look like it was a joke. Steve lingered because he had infinite patience, and needed some company even if his only option in the otherwise empty mansion was Tony talking to himself. Mostly, and he had to quickly correct, "No, I just assumed--sorry--we had this, you know--He liked drawing comics. I'd work, and he'd be making little cartoons, or..." He had to wave a hand, rolling his eyes, whatever, because he mostly didn't stop to see what Steve had been working on in the noise of Tony's lab. By the time Tony was pulling himself away, it was always pressing; he was already late for a meeting, there was a dragon outside the door, or he was already asleep on the table. "You don't want to?" It was quick, Tony's focus already back on the bench like he wasn't braced for the devastating revelation that this Steve didn't even doodle.
