Relax, Princess. I didn't kill him. Just knocked him out for attacking a woman. I'm new to town and didn't know what you did with trash like him, so I thought I'd bring him here. You are the one in charge here, right?

[Despite the precarious situation, his tone is completely relaxed, like he's had similar conversations before. He's certain she'll calm down once she realizes he was just doing his civic duty and let him go on his way. Omega had been that way too, at first. All "who do you think you are" and "you can't do that" but they soon realized the good he was doing not like anyone else was and backed off. Weiss would be the same.]
