Right, hopefully there will be an option to allow the other character's AI to actually choose the response (though some min-maxers may still want the freedom to always choose both characters' responses as well, depending on how traits are finally implemented). If not, regardless of each character's "personality," you'd still be able to force both characters to agree with each other 100% of the time by manually clicking the "I agree with you"-type answer. Anyway, we'll see.
