George: Did you only shave one leg?
Izzie: (starts crying) I know, I'm sorry!!!

And it's not about the sex. It's not... about the sex. It's about that moment afterward... when the world stops. It just feels so safe, so safe. I'm not ready to give that up. I'm not ready to give that up.

"You are flirting with cardio. I am MARRIED to cardio!"

Cristina

[narrating] "Deep down, everyone wants to believe they can be hardcore. But being hardcore isn’t just about being tough. It’s about acceptance. Sometimes you have to give yourself permission to not be hardcore for once. You don’t have to be tough every minute of every day. It’s okay to let down your guard. In fact there are moments when it’s the best thing you can possibly do… as long as you choose your moments wisely."

Meredith

[narrating] "There’s this thing about being a surgeon. Maybe it’s pride or maybe it’s just about being tough. But a true surgeon never admits they need help, unless absolutely necessary. Surgeons don’t need to ask for help because they are tougher than that. Surgeons are cowboys, rough around the edges, hard core… at least that’s what they want you to think."

Meredith

“Being aware of your crap and actually overcoming your crap are two very different things.”

Cristina

You’re Dr. Bailey, you hear everything. And even if you haven’t heard everything I’m sure you heard.

George

Cristina: You could scatter her off the roof.
Meredith: She was afraid of heights.
Cristina: The ashes Meredith. The ashes aren’t acrophobic.

I would've given my dad my heart if I could. If I could've saved him. I would've given him my heart.

George

This is going to be so much fun.

Dr. Hahn

Ashes to ashes, dust to dust.

Richard

[narrating] It isn't just surgeons. I don't know anyone who isn't haunted by something or someone. And whether we try to slice the pain away with a scalpel or shove it in the back of a closet ... our efforts usually fail. So the only way we can clear out the cobwebs is to turn a new page or put an old story to rest.... finally, finally to rest.

Meredith

Grey's Anatomy Season 4 Quotes

I tell you that I love you, and not one word? For 17 days? Where have you been?

Izzie

[narrating] In the practice of medicine, change is inevitable. New surgical techniques are created, procedures are updated, levels of expertise increase. Innovation is everything, nothing remains the same for long. We either adapt to change, or ... we get left behind.
