Meredith Grey (narration): We live out our lives on the surgical unit. Seven days a week, fourteen hours a day. We're together more than we're apart. After a while - the ways of residency - become the ways of life. Number one: always keep score. Number two: do whatever you can to outsmart the other guy. Number three: Don't make friends with the enemy. Oh, and yeah, number four: everything, everything is a competition. Whoever said that winning wasn't everything never held a scalpel. There's another way to survive this competition. A way no one ever seems to tells you about. One you have to learn for yourself. Number five: it's not about the race at all. There are no winners or losers. Victories are counted by the number of lives saved. And once in a while, if you're smart, the life you save could be your own.
