CALLIE: [empurra Meredith] "I kept your secrets. I was discreet. I was a really good friend to you, and I didn't have to be. And then you go and do this?!"
MEREDITH: "Do what?!"
IZZIE: "Hey! Callie! Use your words! Use your words!"
CALLIE: "Panties, Meredith! I'm talkin' about the McFrickin' Code of Silence! The pair of panties I pulled off the bulletin board... not to mention the adulterous McSex I witnessed! Remember that?!" 

MEREDITH: "Hey Callie. I was going to come and find you. What did you want to talk to me about?"
CALLIE: "Panties."
IZZIE: "Er, Callie? What are you up to?"
CALLIE: "I'm going to kick Meredith's ass right now."

DEREK: "You know what says thank you like nothing else?" [mouths 'sex' inaudibly]
MEREDITH: "I'm leaving now."

CRISTINA: "When you got shot, I walked away. And you cannot let that go, can you? I'm sticking now. I'm sticking. Do you know how tired I am? Do you know how scared I am every time we go into surgery? But I do it, for you."
PRESTON: "Do you know how scared I am when we go into surgery? I don't have to just worry about my career now. I have to put yours on my back too."
CRISTINA: "We are a team!"
PRESTON: "There is no team. There is no team! There is only me, once again, making allowances for your emotional shortcomings!"
PRESTON: [pausas] "We shouldn't say anymore."
PRESTON: [pausas] "No. We shouldn't."

CRISTINA: "We crossed the line. Together. I crossed the line with you."
PRESTON: "You dragged me across the line. You made us a team. You told Shepherd I was fine. You said nobody has to know. I was out there on my own. You made us a team.
CRISTINA: "I did what you needed me to do. You were standing there looking at me telling me your whole life was your hands, if you couldn't operate, if you couldn't be Preston Burke."
PRESTON: "That was your concern, not mine!" 

DEREK: "Hear that? I'm a genius."

MRS. O'MALLEY "First Meredith, then Dr. Torres and now this Dr. Hahn."
MRS. O'MALLEY "O'Malley men are studs!"
MRS. O'MALLEY "He's no stud. He's just very handsome."
IZZIE: "Okay people, focus. George is not dating Erica Hahn."

IZZIE: "Well, how much did George tell you?"
MRS. O'MALLEY: "Everything. I'm his mother."
IZZIE: "Okay, then you know that Callie has a little bit out there. I mean I have seen more of that girl's body than I have with my own and she's a little too much information for me. I mean nobody needs to be naked that often... He didn't tell you that? Um, I dunno why they broke up. George seemed to really like her and he kinda needed her. I mean, you remember the whole George and Meredith thing."
MRS. O'MALLEY "Wait! George and Meredith?"
MRS. O'MALLEY "I knew it."
IZZIE: "George didn't tell you that either?"

IZZIE: "Do you mind me asking why you guys switched from Dr. Burke to Dr. Hahn?"
MRS. O'MALLEY "No, we didn't. Georgie did."
IZZIE: "Did he say why?"
MRS. O'MALLEY "Not really, no."
MRS. O'MALLEY: "Did George and Dr. Burke maybe have a falling out?"
IZZIE: "Not that I know of."

PRESTON: "Anything you would have done different, Dr. Hahn?"
DR. HAHN: "Given the size of the wound, I would've given up sooner. So how have you been, Preston? Last time I saw you, you stole my patient's heart. Then you got shot. Karma rocks."
PRESTON: "What brings you all the way from Seattle Presbyterian to Seattle Grace?"
DR. HAHN: "A consult. And knowing how much my being here would annoy you."
PRESTON: "Oh, on the contrary. It's always a pleasure. Though not as much as when you leave."
