Honestly? Arnaud is very fluctuate to me. Even I don't know how to write him without contradicting my own word since I can't really make up a good depiction of him, but I mainly see him as someone who's egotistical, a very conceptualized (??) or "stereotypical" version of it. He's not an actual narc, though. I tend to think if anything gets in the way of his ego he gets very defensive and violent,,,,, I like to think he's also very skittish. Like, emotionally wise. very easy to back up into a corner, as seen in his in-game version where he basically folds the second you enter the church LOLOLOL. but under all of that he has a kind soul I think,,,, just someone that's been through rough patches,,,
