Meredith Grey's Most Defining Moments on Grey's Anatomy

What's great about Grey's is that it helps us feel hope even as scary, inexplicable things happen in the world. It teaches us about forgiveness and change in the face of darkness. Here, the general surgeon becomes severely incapacitated after getting attacked by a patient in a fugue state, enduring everything from broken ribs to a collapsed lung. When Lou, her attacker, reaches out to talk, she accepts his offer and allows him to apologize to her in front of his wife and kids. This is right after Richard takes a walk with her, wisely telling her that forgiveness is a powerful thing (in the context of Derek's death and Amelia).
