This week on Grey's Anatomy a new doc arrives, but she's not a big fan of Seattle Grace; an old friend of Meredith's joins the staff and ruffles some feathers; and Izzie fears she could be seriously ill.
One week after the big Callie/Erica fight, we're still left to wonder what the official story is behind Hahn's departure. While this kind of closure may never come, it's hard not to expect something more. Even when Burke left, we were offered more of an explanation regarding his whereabouts outside of Seattle Grace. For now, all we have to go on is Cristina's elation over Hahn's departure and Callie's emotional struggle to deal with the fallout.
Meanwhile, Meredith reunites with an old friend, Sadie (Melissa George), who happens to be joining the hospital as an intern after a stint at the morgue. With the rekindling of this old friendship comes some jealousy from Cristina, who is left commiserating with Derek over her new third wheel status. The self-pitying stops, however, when they enter Seattle Grace and Cristina reminds Mer (in that snarky way that Cristina does best) that Sadie is just an intern and needs to learn her place.
