Grey's Anatomy and The Time Warp

Forget about FlashForward, it's all about flash sideways and flashbacks. Brothers & Sisters recently announced their casting of their flashback episode but, in the US, this week's it's the turn of Grey's Anatomy.

The episdoe synopsis is "In his new role as Chief, Derek restores the hospital lecture series, and Richard, Bailey and Callie present to the group pivotal surgical cases from their pasts - Bailey reflects on her first days as a shy resident, Callie looks back on a polio case, and Richard recalls a case in which he and Ellis worked on a patient diagnosed with GRID, a virus later called AIDS."

Guest starring will be Sarah Paulson and J. August Richards as Young Ellis Grey and Young Richard Webber and Missi Pyle as Bailey's Former Nemesis, Dr. Nicole Baylow.
