Izzie finds Cristina looking through a microscope and when she notices blondie, she sits and looks at her quietly, waiting for the sales pitch. Izzie, though, just wants to talk about the mind-blowing sex she's having. Apparently the ghost sex is the best she's ever had in her life, and probably the best sex that anyone has ever had, and she can't imagine why anyone would want to do anything else with their time. Izzie laughs in delight and tells Cristina that it's fine that she gives the surgery to Mere, because Izzie is having mind-blowing sex. She finishes up with a manic chuckle, and tells Cristina, "Just thought you should know." Cristina still doesn't say a word.
