Razlo's wife only interacts with the Vault Dweller minimally. She will just ask if they are in need of assistance. If they are, she will defer the Vault Dweller to her husband, Razlo. This is her only interaction in which the Vault Dweller enters dialogue. During the night, she will ask the Vault Dweller to leave her house, as she likes to sleep without disruptions.
If the Vault Dweller attempts to steal anything from the bookshelf next to her and she catches him, she will display a floating line of dialogue saying "Please do not take my things". And then engage in combat.
If the Vault Dweller's Intelligence is less than 4, she will not be able to understand him.
