Reilly, Eve was played by Tracey Ross for the series' entire run.  In 2003, actresses Amanda Maiden and Kimberly Kevon Williams played the character in flashbacks to her childhood and her time as a nightclub singer.  Ross was initially hesitant to audition for the role following her negative experience on "Ryan's Hope", but was attracted to the show after learning about its supernatural and fantasy elements.  Her casting was part of NBC's attempt to include a racially diverse ensemble on daytime television.  She based her performance on Joanne Woodward's role in the 1957 film "The Three Faces of Eve" and Catherine Halsey from Ayn Rand's 1943 novel, "The Fountainhead".

It is a highly pleiotropic disorder that clinically manifests by form of short-limbed dwarfism due to skeletal dysplasia, variable level of immunodeficiency and predisposition to malignancies in some cases.  It was first reported in 1965 by McKusick et al.

Valerie was played by Daphnée Duplaix from 2004 –2008, and temporarily by Siena Goines in 2007.  Jeanmarie originally auditioned for the role of a peeping tom before the role was expanded as the show progressed.  Jeanmarie and Duplaix were both unaware that Vincent and Valerie were the same character until receiving the script and shooting the scenes.  Jeanmarie approached playing Vincent through his abuse as a child by his grandfather Alistair Crane, interpreting him as a character constantly searching for acceptance.  The character received a more uncertain response from the show's other cast members.

Fox, as played by Hartley, was a fan favorite amongst "Passions" viewers.
