Seven years after a very controversial departure from ABC's "Grey's Anatomy," Isaiah Washington will finally return to the medical drama this week, providing audiences with what will surely be another twist in Cristina Yang's (Sandra Oh) love life.

And to get fans ready for his return to the small screen, ABC will relive his dramatic departure by replaying the May 2007 episode "Didn't We Almost Have It All." It will air in the 8 o'clock slot preceding a new episode, "We are Never Getting Back Together." (ABC had originally planned an encore of last week's episode to air Thursday at 8, but decided to go back in the time machine instead.)

After leaving Yang at the altar, Preston Burke (Washington) left without a trace, never to be heard from again. His departure/disappearance was hardly addressed in the aftermath, except in watching Yang recover from the trauma and hearing that Burke received the highly coveted "Harper Avery" award for work he and Yang performed together.

Burke's presence won't be the only throwback this week. The 2007 episode also features old series regulars Katherine Heigl, TR Knight, Eric Dane and Kate Walsh.

This week's episode will show Cristina looking to Meredith (Ellen Pompeo) for advice as she assesses her future at the hospital after she had lost the Harper Avery as a result of the hospital's affiliation with the award. Oh is leaving the show after this season, appearing for the last time in the May 15 season finale.

Washington left after an on-set fight in which he used homophobic slurs with co-star Knight. Knight returned the following season, but Washington didn't, even after a short time in rehab and participating in an anti-hate PSA.
