Killing people is bad Halle-san. [It's said idly though, as if just for the sake of it rather than expecting Halle to actually pay any attention to it]
I can't really blame you though...it's not fair for her to be mean like that. [Agito would do the same thing in that situation. He can't really condemn anyone else for it when his other would do it and he wouldn't say anything against it] If she knows what you're like, she's kind of asking for it by provoking you anyway. [Assuming from that whole 'killed in the future' thing]
