As the OP says pawns don't know who is their King, so to answer your question Nicki, they don't. Also i'm trying to understand this game too lol and now we know that Amine is definitely not a pawn, since he knows who is his king.
As for Martin I remember that i played a mafia game with him and he was inactive in there too so he got replaced. So probably if he doesn't die or he doesn't make a post, i guess he will get replaced again. And idk should we go for lynch him?
