Stefl is acting weird but there is some roles that can explain how he knows that Linkz is town and they are ones that I know he wouldn't want to announce right now. On the otherhand, why say he knows Linkz is town in the first place in that case? I agree that he is acting very strangely but I don't really think mafia Stefl would act this awkwardly for no reason (afterall, most of the stuff he has said, he's done off his own back rather than because he's had to)
