Barbara is a nurse paid by Gaius Baltar to look after his father, Julius Baltar, prior to the Fall of the Twelve Colonies. She leaves this position after Julius stabs her with a knife, claiming that she stole money from him, despite the younger Baltar's desperate offer to pay her hundreds of cubits to stay the night (Daybreak, Part I).
