When we get back, Addison's got Bailey up on the ultrasound table. She says her contractions look like nothing more than Braxton-Hicks. Bailey says that may be, but she recognizes the mild-concern tone in Addie's voice, as she's used it herself on patients. Addison gently tells her that false labor is sometimes the body's way of telling us to slow down. Bailey's all, "I'm a surgeon. There ain't no damn slowing down." Addie tries to get Bailey to understand the realities of her pregnancy, and Bailey says the first thing Addie can do is help her get down off that table. Addison's hair, by the way, is down here, and she looks beautiful, unlike when they pull it back so tightly she's nearly Asian. Pay attention, stylists! Izzie interrupts to tell Bailey there are some questions about Yumi's esophagram. When Bailey's out of the room, Addie asks Izzie to look after Bailey today, and keep an eye out for any painful contractions -- more than five an hour, anything that could indicate pre-term labor. Izzie rolls her eyes, still hating Addison for her mean trick. Addison reminds Izzie that the favor's not for her, and she knows that. Izzie knows, but pretends she doesn't care.
