Surprisingly, it is Bailey (Chandra Wilson) who is the loudest voice as the staffers try to persuade Izzie (Katherine Heigl) not to give up medicine. Meanwhile, Mark Sloan (Eric Dane) scores again, and Addison (Kate Walsh) is once more the prize; Cristina (Sandra Oh) has an uncomfortable meeting with the parents (Richard Roundtree, Diahann Carroll) of the convalescing Burke (Isaiah Washington); Meredith remains torn between Derek (Patrick Dempsey) and Finn (Chris O'Donnell); and Webber (James Pickens Jr.) confronts Callie (Sara Ramirez) over her quirky behavior, just as George (T.R. Knight) walks in. And on the "patient roster" front, a lung cancer victim (Roxanne Hart) decides to throw caution to the winds, with wide-ranging results. ~ Hal Erickson, Rovi
