In the conclusion of a two-part story, things are sunny indeed (at least temporarily)for Cristina (Sandra Oh) and Burke (Isaiah Washington), but things don't look so good for George's cancer-patient father (George Dzundza); even so, this medical crisis serves to bring George and Callie closer together. Elsewhere, Meredith (Ellen Pompeo) has harsh words for Derek (Patrick Dempsey) and even harsher ones for her estranged father Thatcher Grey (Jeff Perry). Bailey (Chandra Wilson) is none too thrilled when she is forced to keep a secret. And the money for Heather's operation is provided by an anonymous source (Hint: which of the series' characters has just come into a multimillion-dollar inheritance?) ~ Hal Erickson, Rovi
