Grey's Anatomy Quotes

Amelia: I think I'm falling in love with Owen Hunt, and I'm really afraid that it's gonna destroy me.
Derek: It wouldn't be love if it didn't.

Did you say it? 'I love you. I don't ever want to live without you. You changed my life.' Did you say it? Make a plan. Set a goal. Work toward it, but every now and then, look around; Drink it in 'cause this is it. It might all be gone tomorrow."

Meredith (closing voiceover)
