Meredith: I don't think that things are simply right or wrong. Things are more complicated than that. This was more complicated than that. It's complicated that it was Adele and Richard. It's complicated that we have a drug in a box that could help her. There's nothing simple about that. I am very sorry that I messed everything up, but I would do it again.
Derek: I don't know how to raise a child with someone who doesn't understand that there's a right and wrong in the world.
Meredith: So, now I'm gonna be a bad mother. That's where we're going with this?
Derek: You've been saying it for weeks. Maybe you're right.

I always said I'd be happier alone. I have my work, my friends, but someone in your life all the time? More trouble than it's worth. Apparently, I got over it.

There is a reason I said I'd be happy alone. It wasnt because I thought I would be happy alone. It was because I thought if I loved someone and then it fell apart, I might not make it. It's easier to be alone. Because what if you learn that you need love? And then you don't have it. What if you like it? And lean on it? What if you shape your life around it? And then it falls apart? Can you even survive that kind of pain? Losing love is like organ damage. It's like dying. The only difference is, death ends. This? It could go on forever . . .

[narrating] We have to constantly come up with new ways to fix ourselves. So we change, we adapt. We create new versions of ourselves. We just need to be sure that this one is an improvement over the last.

Adapt or die. As many times as we've heard it, the lesson doesn't get easier. The problem is we're human. We want more than just to survive. We want love. We want success. We want to be the best that we can be. So, we fight like hell to get those things. Anything else feels like death.

I'm a surgeon and I'm a good surgeon and I want to be a good mother. Honestly, I don't know much about it, but I'm ready to learn and I'm a fast learner. And I will do whatever it takes to be a good mom.

Meredith: I put my hand on a bomb in a body. She could think that was...
Cristina: Suicidal? No, it was brave
Meredith: I told a shooter to shoot me.
Cristina: Change the subject.

My mother was about as nurturing as a steak knife.

We've all heard the saying. It's one of those things you learn in seventh grade science class. Adapt or die. Adapting isn't easy though. You have to fight your competition and off their attacks. And sometimes, you have to kill. You do what you need to do to survive.

Just when we think we figured things out, the universe throws us a curveball. So, we have to improvise. We find happiness in unexpected places. We find ourselves back to the things that matter the most. The universe is funny that way. Sometimes it just has a way of making sure we wind up exactly where we belong.

Derek: I, Derek Shepherd

Callie: I love you.

Derek: Let's adopt this baby.
Meredith: What? Are you serious?

Grey's Anatomy Quotes

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."

There's a reason I said I'd be happy alone. It wasn't 'cause I thought I'd be happy alone. It was because I thought if I loved someone and then it fell apart, I might not make it.
