-Olesya Rulin guest stars on the mid-season finale of ABC Family’s “Greek” on November 2 at 9pm EST. She shows the Greek system how to really sing and dance.

In the “Friend or Foe” episode, the ZBZs are in it to win it for the biggest blue ribbon competition – Songfest. However, the night before the ZBZs are going to perform, Panhellenic president Katherine (Nora Kirkpatrick) disqualifies the house’s routine on a technicality. It is up to pledge Abby (Rulin) to save the day by choreographing an all new dance.
