Winston Story

The Seattle Grace staff continue to mourn George's death; George's mother arrives but is unsure of what to do with his organs.

Meredith, Cristina, Izzie and Alex spend their first day as residents with their own interns, including George, repeating his internship after failing his exams, and Meredith's half-sister. Cristina searches for Burke, who is nowhere to be found and Richard resumes his position as chief of surgery.

Cristina tells Alex and Bailey about Izzie's condition; Mark is doing a face transplant on a patient and Owen and Alex are the donor gathering team; Bailey sends Callie after Derek to bring him back and Callie ends up staying in his vortex of self-pity.

Derek searches for the best way to propose to Meredith; Callie tries to convince Mark not to blow his chance at real love with Lexie, despite his fear of Derek finding out; Izzie learns she has anemia.

The hospital has a pipe break which causes a huge flood; Meredith quits therapy but Dr. Wyatt doesn't believe she is finished.
