Izzie: If you wait a few minutes you can have a piece of cake, baked chock full of love. Actually chock full of unrelenting, all-consuming rage and hostility, but still tasty.
Meredith: Why do I keep hitting myself with a hammer? Because it feels so good when I stop.
Meredith: I hate you! (takes a slice of cake from Izzie) And your cake!
Izzie: No, no, the cake is good.
When Izzie leaves the house, she has a purple travel coffee mug. When she gets out of the car, it is a disposable mug, but when she leaves the locker room, she is holding the purple mug again.
