[@Fading Memory] Odaya Bilica: Audrey gets along very badly with the Bilica family at large. She is marginally kinder to Odaya, particularly when she is away from her brothers. Audrey operates under the assumption that Odaya has a hard time as the only girl, and tries to be a good influence, in her own way. It is worth noting that by most traditional standards, Audrey is a categorically bad influence. 

EDIT: proposed nickname for Odaya, based on the theme of Mustelids from the rest of her family: Otter.
