7x01 With You I'm Born Again

Dr. Meredith Grey: [voiceover] When we say things like "People don't change" it drives scientists crazy. Because change is literally the only constant in all of science. Energy, matter, it's always changing. Morphing. Merging. Growing. Dying. It's the way people try not to change that's unnatural. The way we cling to what things were instead of letting them be what they are. The way we cling to old memories instead of forming new ones. The way we insist on believing, despite every scientific indication, that anything in this lifetime is permanent. Change is constant. How we experience change, that's up to us. It can feel like death, or it can feel like a second chance at life. If we open our fingers, loosen our grips, go with it, it can feel like pure adrenaline. Like at any moment we can have another chance at life.
Dr. Cristina Yang: [to Dr. Owen Hunt] I do.
Dr. Meredith Grey: [voiceover] Like at any moment, we can be born all over again.

Dr. Owen Hunt: [talking to Derek] I need a best man. I... I know... I know we're not that close, but... I don't know. You being married to the other twisted sister, [chuckles] I... I just thought it... it kinda made us like brothers or something.

Dr. Cristina Yang: [looking through a bridal magazine] God, the women in these magazines... Some of them are actual brides, you know, they're not all models. All smiling... It's like the only thing in the world that matters is that they find the perfect shoes to match that dress. God, you know, I knew these girls, I went to school with them... It's funny. I used to feel sorry for them. They're simple girls. They just wanna find the guy and get married, you know? Live. I don't know, I think you're either born simple or you're born... me. I wanna be the person who gets happy over finding the perfect dress, I wanna be simple, 'cause no one holds a gun to the head of a simple girl.
