EXPLORE All The Shades of Grey

Meredith: [voiceover] In the hospital, we see addiction every day. It's shocking how many kinds of addiction exist. It would be too easy if it were just drugs and booze and cigarettes. I think the hardest part of kicking a habit is wanting to kick it. I mean, we get addicted for a reason, right? Often, too often, things that start out as just a normal part of your life at some point cross the line to obsessive, compulsive, out of control. It's the high we're chasing, the high that makes everything else fade away.

Mark: Let me guess, you and Meredith are back together and you've been up all night doing the horizontal salsa.

Derek: Mambo. Horizontal mambo. Meredith and I, we're just friends.

Mark: Sexy friends.

Derek: You're like the worst, most juvenile human being I've ever met in my life.

Mark: You know the first step to recovery is admitting you have a problem?

Derek: How many nurses have you slept with this week?

Mark: That's not a problem, man. That’s an adventure

Bailey: Would you look at the residents, big snazzy residents, standing around playing with house wares.

Cristina: Turn a blind eye and the soup tureen's yours.

[Pager beeps]

Cristina: Carnage in the pit. My day is improving. [Cristina walks away and turns to her interns]

Cristina: Follow. [Interns run to follow her]

Lexie: We're not gonna round?

Cristina: Carnage trumps rounds, Three. Write that down. Carnage always trumps rounds.

Chief: What do we have?

Callie: Gas main blew in an apartment building, five injured, some badly.

Cristina: Excellent... Horrible, horrible — sad.

Meredith: Hey, what's the 911?

Cristina: Mama is here.

Meredith: Your mother?

Cristina: No, not my mother. Mama. Mama is here.

Meredith: Oh, Burke's mother.

Cristina: Yeah, make the synapses fire a little more quickly, Meredith.

Meredith: We agreed, S and M only.

Derek: S and M?

Meredith: Sex and mockery.

Meredith: [voiceover] The thing about addiction is it never ends well, because eventually, whatever it is that was getting us high stops feeling good and starts to hurt. Still, they say you don’t kick the habit until you hit rock bottom, but how do you know when you’re there? Because no matter how badly a thing is hurting us, sometimes letting it go hurts even worse.
