How do they behave within a group? What role(s) do they take? Does this differ if they know and trust the group, versus finding themselves in a group of strangers? Why? - Arsene
I think I’ve said this before, but among personas, Arsene takes an unofficial leader position. He treats the personas of the gang with respect and like best friends except for one but he will be the one to break up fights and sort out disagreements. He’s also usually the first to give commands in infiltrations and fights if the users aren’t there for any reason.
This was actually pretty much how he treated his friends and acquaintances in life, too. Granted, Arsene had a bit more formal authority over them given his skills and achievements, but he treated them pretty much the same. He treated them well but took command in their heists.
With the Phantom Thieves themselves, Arsene usually takes the role of protector and bystander. Though at times, he can’t help but tease the gang.
With strangers, Arsene will usually just watch and observe and offer commentary here and there. He takes great strides to keep from standing out, and also to keep from blending in too much. He’s observant, but he’ll crack jokes and counter points of view to keep people from suspecting who he really is. This doesn’t always work, but he does his damnedest.
