Seattle Grace has a new arrival: the saucy and sexy Sadie Harris. Sadie’s an old friend from Meredith’s wild days and has gotten into the intern program at SGH. But who is this woman and why the heck is she calling our Mer “Deth”? She needs to get with the nickname program!
More big news: Erica Hahn has left Seattle Grace! Obviously the Chief’s not happy about losing his Chief Cardiologist, and Callie won’t even talk about the epic fight they must have had the night before. Izzie can’t be too sad to see Erica go, though, since now the threat of being turned in for the whole stealing-a-donor-heart-for-Denny thing is over, too. Not that Izzie’s in the clear -- she's still got a big problem. Her visions of Denny aren’t going away.
