'Grey's Anatomy': Isaiah Washington 'was a nervous wreck on the first day' of filming his return episode

greys-anatomy-burke-is-back.jpg It's been seven years in the making, and on Thursday (May 1), it's finally happening. Burke is back on "Grey's Anatomy!"

Isaiah Washington makes his big return to the ABC medical drama seven years after exiting the series in the episode, "We Are Never Getting Back Together," as a part of Sandra Oh's farewell as she departs the series after Season 10. Creator Shonda Rhimes has said that it was necessary to bring Burke back to give closure to Cristina's story before she leaves.

Zap2it caught up with Washington -- who now stars on The CW's hit new series "The 100" -- to discuss his highly-anticipated return episode. Check out what he had to say about being back on set below:



"Grey's Anatomy" airs Thursdays at 9 p.m. ET/PT on ABC.
