@Vincentius true, but it was weird he didn't even try. I mean, a little boy panicking and not saying anything is cool, but he's a reincarnated guy and I just think he gave up too easy. His explanations that he DID give seemed like arrogant provocations. All she said was follow me to the castle, and he said, I refuse. Like, really? So arrogant for a boy from the slums. He should have said something like "Okay, but don't you want to see the real assailant first? I left him unconscious over there."
Sure, they might not believe him but "I refuse" just seems so dumb. Other guards eventually found the unconscious guy presumably way later so... but w/e, the plot must go on, its cool.
