At last, it seems like the show is actually getting somewhere, the ending of the previous episode having introduced enough new elements to spice up the plot and give the supporting characters the limelight they deserve.
After Izzie and (to lesser extent) Cristina, it's time for Dr. Bailey (Chandra Wilson), aka The Nazi, to shine. In case one should need a reminder, she caught Meredith and Derek doing it in a car and spends most of her time giving both of them hell. George and Izzie aren't that happy either, as they believe Dr. McDreamy (that would be Derek's nickname) is favoring Meredith. Meanwhile, Cristina is eager to keep her affair with Burke a secret, which turns out to be very easy when every intern's attention is diverted onto a woman with a huge tumor. Plus, Izzie gets to perform major surgery all by herself when no one else is around.
Not that the last two plot strands really matter, right? Unlike ER or House, Grey's Anatomy doesn't care too much about its hospital setting (at least in the first season). After all, the premise - the ethical questionability of sleeping with your boss - could work in a lot of contexts. Thankfully, the fiery Wilson, who has always had a great sense of comedic acting (see her one-scene cameo in the fifth season of Sex and the City, for example), gives a riotous performance that make most other shortcomings forgivable. In fact, her vitality is quite contagious: Patrick Dempsey, who has the ungrateful task of sharing most of his scenes with Ellen Pompeo (not a bad actress, but she does play an uninteresting role), becomes a completely different person when he has the chance to measure himself with the Nazi's acerbic remarks, and that is truly worth watching.
