so, me and @thequeenofspies got bored and spend an unholy time founding what cigarettes they are all smoking; here you go :

moulinier - "Royale Rouge"

(it was actually the easiest to find bro is always smoking i have so many screenshot of his pack of cigarettes)

jacquard - "Algeria"

(possibly the hardest, there's only one scene when you can kinda see it and it's so blury)

moïse - "Celtiques"

(i think we can see them in other shots but i'm lazy)

merlaux - "Gauloises"

(it's funny bc it's the light version of the Celtiques also this one was very easy too)

for calot, we can't tell bc he uses a little box where you put your cigarettes in so eh

and for mercaillon well fuck him i don't want to know

and i find those little details so cool bc it weirdly actually tells a lot about them ? like merlaux smokes des gauloises and they're the classic french cigarettes, very basic, almost a french symbol. moises smokes des celtiques, very french but older than the gauloises, more nicotines, i think we could say it link him to merlaux like an older him (and since he's his father figures it's rlly cute). jacquard smokes des algeria which is very obvious, he probably buy them when he's in alger and they are (according to my mom) cheaper so it goes with his money oriented mindset (+ it also goes with his love for his work zone and you can't tell me jacquard doesn't actually deeply love algeria bc i will not believe u this man is in his element there i will not elaborate). moulinier smokes des royales, kinda expensive cigarettes, very classy, goes with his lifestyle (champagne, fancy bars like the darling club, fancy clothes as we can see him wearing a lot of different suits). and as for calot, the fact that he uses a metal box for his cigarettes also tells a lot, he is a mysterious and paranoid character, probably doesn't want anyone to know anything about him (and we actually don't know a lot about him compared to other characters).
