Below is a gallery of promotional photos from "Time Warp," this Thursday's flashback episode of Grey's Anatomy. Viewers will gain past insight into the lives of Bailey, Callie and the Chief as they recall noteworthy cases as part of Derek's newly-instituted lecture series.

The Chief will be traveling back in his mind to 1982, while Drs. Bailey and Torres will be shown in the slightly-more recent past, circa 2004. Should be interesting to see.
