Plot

Izzie returns to the hospital under probation, and George tries to make amends with Callie. Meanwhile, Cristina's deletion of Bailey's name on Burke's OR board makes her assume he is against her, and Derek's irritating sister Nancy visits.

Derek's sister comes to Seattle for a visit, and seems more into the extended family and gossip surrounding his divorce from Addison than into him. Meanwhile, the interns are not the only ones jealous of Cristina's opportunity to scrub in with Preston on a "Humpty Dumpty" procedure, and Bailey takes it personally when she learns she's been scrubbed, herself. George works with Addison on a very unusual case and Alex envies him.—Moviedude1
