@ezdez I recall that it's inferred that Roxanne has strong suspicions early on that MC is a hero (saying that he'll do great things and she wants to be part of it) and it only gets reinforced as he pulls off more shenanigans. I'd say by the time Dragon girl comes in that she's probably pretty sure she's right. It might actually be part of the secret discussion she had with the elf that made her a lot more tame.
