I found more info on her character which you can see below. Look's like an interesting character.
SourceLost alumna Emilie de Ravin is set to co-star in another ABC drama series project, pilot Americana, a soap about a famous fashion industry clan. It centers on iconic fashion designer Robert Soulter (Anthony LaPaglia), the patriarch of a sprawling family who just welcomed a new member, a young designer whose shocking arrival turns the family and the legendary label inside out. De Ravin, repped by Gersh and manager Darren Goldberg, will play Robert’s chic and outgoing daughter Francesca who is the head of events at Americana but Robert doesn’t consider her a candidate for the heir to his empire, which may have treacherous consequences.
