For example, Lyle helped the MC to make bombs without asking for anything in return, and after that always being with him in his business. Or the MC negotiation skills being non-existant. Or the Earl they see in Est being super polite with someone who is basically a nobody.
there are bombs, and he is able to create them just like that. No explanations. Last time I checked, even an engineer would find that super difficult without any prior base industry to lean on. And also, NO ONE thinks this is great for wars? And outside of that: gunpowder is invented, but no one cares until he does something with it???
