"Uh.... I've always been a big fan of multitasking." Tony admitted with a shrug of his shoulders. He needed to keep busy, not just his hands but his mind too - and sure he could tinker with a bot or some new bit of tech or some program or whatever, but sometimes he needed a little bit of added stimulation. And sure he loved to listen to rock but not even that could cut it at times - so audio books filled that gap nicely when necessary. "I mean I need a little bit more than just imagining but it's plenty for some people, I'm not really your average person either." So his experience was a little different really.
It wasn't a problem at all to offer Steve a bit of reassurance that if he found something he'd let him know about it. But the odds of it happening got smaller every day. Not that Tony was going to tell him that, not while he was still getting his feet under him
But the idea of others showing up? Well that was something else. "Honestly, I can't say for certain. Some people have a lot of others from their worlds showing up, like Natasha." He decided going for one of them he didn't have to explain too much, "There are like 4 others from her world here. But for some people there's just the one." Like him. "So we don't really know, there doesn't seem to be a lot of reason or explanation for it. It just is the way it is."
"But I'm trying to figure it out, don't worry." He added quickly.
