Grey's Sings the Blues, Fans Don't

It's about time!

When Grey's Anatomy returns this Sunday at 10 Eastern after a four-week layoff, fans will be elated despite the episode's sad-sounding title, "Blues for Sister Someone." The title is the name of a Lenny Kravitz song, and music plays an even greater role than usual this week as Dr. Burke must treat a legendary jazz musician who happens to be his hero.

Addison, meanwhile, is introduced to a Catholic patient and mother of seven, whose husband refuses to use contraceptives. She's not the only Shepherd dealing with a dicey issue, as Derek treats a divorce attorney who asks him if Derek is in need of her services. Hmm. Dr. & Mrs. Dr. McDreamy appeared to have turned a corner, but does this mean things are still rocky between them?

That remains to be seen, as does how their marriage impacts Meredith, who is courted by Finn Dandridge (Chris O'Donnell), her dog's vet. While our sources haven't clarified anything specific, there's also a good chance that George's relationship with Calli continues to heat up, and that Denny will also be featured. Cracking jokes. Wooing Izzie. Waiting for a transplant, hanging on for dear life. You know, the usual. Regardless, it should be fun to watch! Much better than some silly recap episode.
