Touya approached her stand looking for a good luck charm but she tried to trick him into buying something else. He refused and before anything else could happen she noticed Ridovia Lorenzetti approaching and quickly packed up her stuff and ran off. Touya ran into Balbina around 5 more times throughout the day but each time she quickly packed up and ran off due to Ridovia's approach. After finding out that Touya was trying to find a good luck charm to help against his son's misfortune, Ridovia ran off and dragged Balbina towards him. Once he explained that he was trying to save someone Balbina decided to help him with Ridovia. She then took out some strange dolls and dried plants out of her bag and imbued them with some minor magic and gave him instructions of how to use them to help against his son's misfortune. Afterwards she followed Ridovia to Oriana Thomson and explained to her why Ridovia was so happy. While Ridovia was going on about her meeting and how happy she was, Balbina ran off somewhere once again.
