It's probably all the Lost fever that has both Losties and non-Losties gripping with concepts of time and space, but Grey's Anatomy will also find itself doing some time-jumps on its upcoming installment. But unlike Lost and its crazy mind-numbing storylines, Grey's Anatomy will be infinitely simpler: people will just be kind of younger.
On "Time Warp" we'll get to see Bailey (Chandra Wilson) before she became the Nazi that she is, the beginning of the Chief's (James Pickens, Jr.) affair with Mer's (Ellen Pompeo) mom Ellis, and Callie (Sara Ramirez) pre-Seattle Grace.
On the episode, Derek (Patrick Dempsey) as interim Chief, restores the hospital's lecture series.
As members of the panel, Richard, Bailey and Callie all discuss pivotal surgical cases from their pasts, including the Chief's recollection on working with Ellis on a patient diagnosed with GRID, the virus that would be known as AIDS.
J. August Richards and Sarah Paulson are set to play the younger versions of the Chief and Ellis.
