Grey's Anatomy, Season 6

Meredith:
[voiceover] In order to get a good diagnosis, doctors have to constantly change their perspective. We start by getting the patient's point of view, though they often don't have a clue what's going on. So we look at the patient from every possible angle. We rule things out. We uncover new information, trying to get to what's actually wrong. We're asked for second opinions, hoping we'll see something others might have missed. For the patient, a fresh perspective can mean the difference between living and dying. For the doctor, it can mean you're picking a fight with everyone who got there before you.
