Izzie stands in the doorway, listening to Sav explain that she needs this surgery because of all the women in her family who've had ovarian cancer. Weiss disagrees, saying she doesn't have cancer, and this is crazy. Sav argues that she has the gene mutation, and Addison adds that this mutation gives Sav up to an eighty-five percent chance of getting cancer. McDreamy, at the other end of the table, says yeah, but there's a fifteen percent chance that she won't. Oooh, a whole fifteen? Not great odds. They all start arguing at once, and Sav tells McDreamy that until he grows a uterus and watches his mother die from this disease, he doesn't get a vote. McDreamy asks Addison, "She tell you they're trying to get pregnant?" Addison says yes, she knows. McDreamy thinks having a hysterectomy might throw a wrench in that. I'll say. And it's something I also really don't understand: either you're trying to have a baby, or you're planning on getting rid of your uterus, but you can't do both, sister, because you still need it...how to say this? FOR THE BABY TO LIVE IN. Sav pushes another one of my hot buttons when she says they can "just adopt," as if it's as easy as going on down to the K-Mart and picking one out, but Weiss says he just can't handle all this. He doesn't want to "just adopt," he wants Savvy and all her girly parts. Sav screams that she's not talking about this. Izzie looks stricken throughout all of this, by the way. McDreamy says they all need to just take a deep breath and think about this. Addison's mouth drops open at this, and Sav says she's already thought about it. "This is going to happen." Addison tells Izzie to get her pre-op labs ready, and schedule her for surgery. The boys start yelling. Addison cuts them both off: "She is MY patient, Derek." The surgery is happening tomorrow, she says, and tells Izzie to get moving. Damn.
