I was talking in deadchat with a traitor who killed me while I was traitor but I had foreigner trait, so when he told me he said the codewords but I couldnt understand I got triggered. So I think that traitors/antags with foreigner trait should spawn with both uncommon and common.
Also, if you don’t think so, at least do it for team antags. Imagine headrev can’t speak common. bruh.
