Don't Deceive Me (Please Don't Go)

"Doctors practice deception all the time. We give vague answers to hard questions. We don't talk about post-op pain. We say, "you'll experience some discomfort". If you didn't die, we tell you, "the surgery went well". But the placebo has to be the doctor's greatest deception. Half of our patients, we tell the truth. The other half, we pray that the placebo effect's real. And we tell ourselves that they'll feel better anyhow, believing help's on the way, when, in fact, we're leaving them to die. Doctors practice deception every day on our patients, on their families. But the worst deception we practice is on ourselves. Which is why sometimes, it takes us a while to realize that the truth has been in front of us the whole time."

Quotes

 * Arizona: (to Callie) Shut up. Just shut up. You don't get to tell me that we're not together. We are together. Because I love you and you love me, and none of the rest of it matters. We are together. And if you ever sleep with anyone else again, man or woman, I will kick the crap out of you. Now you sit your ass back down there because that's my baby in there. I don't want anything happening to my baby.


 * Mark: I saw the heartbeat today. It's my kid in there. It's part of me. Is there any way we can - please -
 * Lexie: How the hell did you get me into this position twice? It's-it's-it's unbelievable! You are UNBELIEVABLE! storms out and slams door


 * Alex: (to Derek) You need to get over this thing where you're just thinking of her as your wife, because your wife is the only person twisted enough to handle this crap.


 * Callie: You have to say something. Words. Make words.
 * Mark: Holy crap.
 * Callie: Yep.
 * Mark: A baby?
 * Callie: Yep, growing like a weed in my uterus.
 * Mark: Not like a weed, like a mighty oak. (Callie looks confused) We're gonna make great parents.
 * Callie: Mark, you don't have to do...
 * Mark: (puts a hand on her stomach) Are you kidding? That's my kid in there, I'm a dad. (Callie laughs) We're parents. Of a baby!
 * Callie: (smiling) Okay, you're in.
 * Mark: Should we get married?
 * Callie: (smile fades) Oh, no. I mean, I'm all for raising a baby with you, but there's a line.
 * Mark: You're right, that's good 'cause I'm in love with Lexie... Oh my God, Lexie. What am I gonna tell Lexie?
 * Callie: Okay, you think about that.


 * Mark: Well, what did Arizona say?
 * Callie: She said she's in.
