Before Geralt can talk to him he must first defeat the Wicked Witch, who wants to bake Jack. After the boy is freed, he will tell Geralt and Sylvia Anna that he doesn't have the magic beans anymore since Anna Henrietta hid them so that her sister couldn't flee from the illusion. He also says that another lad named Joss should know where they are.
