In this scene from "The Becoming," from the fourth season of Grey's Anatomy, Dr. Meredith Grey prepares for an operation in her clinical trial with Derek. But what she's really thinking about is something altogether different.
Derek: I am calling post-it, Zola, Bailey, the tumors on the wall, ferryboat scrub caps. I thought D.C. was everything. I was wrong. You... you're everything. I love you and I'm not going to stop loving you. I can't live without you. I don't want to live without you, and I'm going to do everything in my power to prove it. Meredith: I can live without you, but I don't want to. I don't ever want to.
