On the verge of signing their divorce papers, Addison (
Kate Walsh) and Derek (
Patrick Dempsey) have second thoughts--and Meredith (
Ellen Pompeo) fumes from the sidelines. Recovering from her miscarriage, Cristina (
Sandra Oh) proves the old adage that doctors make the worst patients. Kindhearted George (T.R. Knight) is run ragged by Meredith's delusional mother Ellis (Kate Burton), who imagines that she is still a busy surgeon with tons of patients. Bailey (
Chandra Wilson), aka "The Nazi", shows her human side when she is reunited with a young cystic fibrosis victim (
Thomas Ian Nicholas). And Alex (
Justin Chambers) worries that his medical career may end before it even gets properly under way. ~ Hal Erickson, All Movie Guide
