He waves and heads off.
He realizes halfway through his next class he has no easy way of causing the conversation to be about the Second Punic War without just saying, "Hey, do you want to hear about some really cool military history?" This is a problem, since saying that is Terrifying. Well, he can just read up on things anyway and practice and see if there's some way to bring it up. And maybe just do the terrifying thing. Maybe it would go fine? Probably it would go fine Maya did basically that today. And he can just have the practice and reading up he did be secret so it isn't obvious how much it means to him and they won't judge him.
It's only been a month since he listened to favorite history podcast covering the Second Punic War, it's easy to catch himself back up to speed. So, what things should he include in the background? Obviously they should know the rough extent of Rome and Carthage. A tiny bit of the First Punic War. It's important that Rome won that one. And of course some of Hannibal's background, it really does add to the drama of the whole situation. And then the whole arc of Hannibal's campaign in Italy, the general shape, his absurd invincibility on the battlefield, Rome's refusal to stop feeding him armies. The whole thing with Fabius. And maybe ending on Hannibal losing to Scipio in Africa? He's not quite sure. He practices saying certain things in his head, works out a structure of it all, and hops back and forth between doing that and browsing the internet vaguely for the rest of his night.
