Last night's episode of "Grey's Anatomy" was filled with surprises. As I predicted last week, Christina lost the battle of silence with Burke. After the death of his father, George turned to sex with Callie as his form of denial, leaving the poor girl totally worn out. While Meredith and McDreamy attended a dinner party at Christina and Burke's place Christina accidentally let out that the chief had asked Burke to step in as chief, which in turn infuriated McDreamy. The chief got a bit of his own medicine when he discovered that his estranged wife had a new man in the house when he came to announce his retirement to her. I can understand --- she was tired of waiting and I would have been too after all of those years. Addison resorted to avoiding Alex, despite his alleged lack of interest in her. The final shockers of the night included two marriage proposals, one from George to Callie, the other from Burke to Christina. My guess is that Christina and Burke's wedding is a lot more likely to happen than George and Callie's. I think he poppped the question on impulse, and he couldn't possibly be serious at a time like this. Or could he?
