The plots this season are the traditional Grey's cross of the dramatic (a horrible campus shooting fills the hospital with victims; a plane goes down in Puget Sound) and the deeply personal. After a couple of seasons of stability, Meredith and Derek find themselves at a horrifying crossroads. And death looks one of the cast members right in the eye. Season seven also includes the famed musical episode, which reminds the viewer why Ramirez was a Broadway star before she signed up with Grey's. Her solo on Brandi Carlile's "The Story" will give viewers goose bumps and maybe a few tears. It's a standout performance. The set includes a very funny gag reel, some interesting deleted scenes that seem worthy of having been included, and some singing outtakes of some of the songs most closely associated with Grey's Anatomy. Turns out the talented cast really does know how to save a life. --A.T. Hurley
