Tom and Lynette learn more about their new neighbours, Bree answers a big question, and Betty loses something precious. Meanwhile, Gabrielle revisits her past when old friends come to town.

Cristina and Meredith try to put their differences aside to treat a prisoner on death row with a serious brain injury; Bailey is put on her heels by a new pediatric surgeon.

Cristina and Burke's wedding day arrives - along with the interns' first exam results - and a successor to the Chief is named, as Callie and George make a big decision about their relationship.

Finn gives a health update on Doc, Meredith is assigned to work with Callie for the day while George gets paired with Derek, and Burke and Izzie continue to try to find a heart for Denny.

Meredith is mortified when her "one night stand" shows up at the hospital suffering from priapism and needing medical attention; a woman carrying quintuplets is overwhelmed by numerous medical issues as she navigates her high-risk pregnancy; and Alex's shortcomings frustrate Izzie.

The nurses at Seattle Grace Hospital go on strike, leaving the doctors to fend for themselves; Meredith's mistake in treating an elderly patient is brought to light by the patient's friends (June Lockhart, Betty Garrett and Rae Allen) and Izzie treats a pregnant teen.
