Tony had to sit back a little and think about that - about the title that the Doctor was putting on him. He hadn't really considered it before, he'd just jumped in headfirst to help however he could, but he hadn't thought that had made him anyone's leader. Particularly since someone like Steve was here, too. "Maybe," he said, because it seemed like a stupid thing to question. It was best to just... take charge. He owed it to a lot of people to try his hardest.
He peeked at the Doctor's sketch even while Strange showed off with another light show. Turned out, yeah, not much was different at all about the Stones from one dimension to another. Maybe they were just a constant. Things that deserved to be put into black holes. Tony rubbed his hand over his face, sighed a little. "I'm so fucking tired of these stones," he admitted.
"Water's no problem, but I'll get people to bring back the bottled sort if they find it from now on," he said, checking a mental box. "Food is a work in progress - scavenging only does so much, I agree. So who knows anything about growing things, because I'm not that guy." The power grid he'd already taken care of. "You get me a list of the basics, Strange. You know my usual method for injury is waiting for death to make a point."
He drained his coffee cup. "And we should meet up every so often. To keep updated."
