Are there consequences for not giving Wolfs Bane to Bernard/Logan??
If you don't give them wolf's banes at the first time. They will lose control and running to the forest (Wolven den). You need to find them at night and beat them to bring them back. After that, there are events which you need to cure them to complete Werewolf event just like when you give them Wolf's banes. But if you give them Wolf's banes, they will like you more. But if you lie about lack of remedy, they will like you less.
