At some point during surgical residency, most interns get a sense of who they are as doctors and the kinds of surgeons they are going to become. If you ask them, they'll tell you they are going to be general surgeons, orthopedic surgeons, neurosurgeons. Distinctions which do more than describe their area of expertise, they help define who they are, because outside the operating room, not only do most surgeons have no idea who they are, they're afraid to find out.

What I Am is the fourth episode of the third season and the 40th overall episode of Grey's Anatomy.

Short SummaryEdit

Dr. Mark Sloan joins the staff as the new head of Plastic surgery and instantly rubs up against everyone. Addison is distracted and her medical judgment compromised by Mark's arrival, and similarly, Derek is also distracted, but clears Burke for surgery. Izzie meets with Denny's father, who is also named Denny and who reveals a bombshell for Izzie. Meredith's policy on dating two men is getting to her, and the interns and Bailey suspect she's pregnant. However, it turns out to be appendicitis. Meredith is put on morphine for the pain, and hilarity ensues, but not for everyone around her.

Shawn, 62, was two days post-op on minimally invasive heart surgery. He was all set to be discharged, but before that could happen, he smoked a cigarette and ignited his oxygen supply, causing burns to his face and a small hematoma to his occipital region. Mark made a plan to treat the burns, but first called for a neuro consult. Derek recommended a day of observation before proceeding with burn treatment. Despite this recommendation, Mark operated immediately, removing the dead tissue and applying live cells. The hope was that they would take in a few weeks, but he was advised that his face wouldn't be the same as it was before.

Rebecca BloomEdit

    • Pregnancy
  • Treatment:
    • C-section delivery

Rebecca was at 8 cm dilation, but her baby was only at minus 3 station. Because she had a "natural birth plan," she refused a c-section. Later, the baby started having late decels and she was forced to have a c-section.

Episode StillsEdit


Cristina: Holy crap, are you pregnant?!
(everyone stops and stares and Meredith)
Addison: Oh great, an adulteress love child.
Derek: Goes along with an adulteress sociopath. (walking by her) Meredith!

Cristina: So, who's the father?
Meredith: I’m not pregnant.
Cristina: I didn’t know I was pregnant when I was pregnant either. But the abdominal pain, fever and the nonstop vomiting?
Meredith: I’m not pregnant.
Cristina: You don’t know who the father is, do you?
Meredith: It would have to be Derek’s, there’s no way it could be Finn’s.
Cristina: You haven’t had sex with the vet yet? You gotta get out of that relationship immediately.
Meredith: I can’t be pregnant, can I?
Cristina: With a McBaby!
Meredith: Was I this mean to you when you were pregnant?

Meredith: (to George) When I'm on the table, keep me draped. Too many people have seen me naked already. I'd like to keep whatever dignity I have left. (sees Mark) It's McSteamy. McSteamy! Yoo hoo!
Mark: McSteamy? That's what you're calling me now?
Meredith: Yes, but I don't think you are supposed to know.
Mark: How's my favorite dirty mistress?
Meredith: Haven't you heard? Now I'm an adulterous whore!

Denny: Dad, mom...It's me. I'm calling from Seattle Grace Hospital where the - the beautiful, talented and incredibly stubborn Dr. Isobel Stevens has, she's just given me a brand new heart and promised to marry me. I know we've had our differences and I'm sorry we've been out of touch. Believe it or not I was - I was trying to make everything better. I know you're angry and I hope you'll forgive me. It turns out, sometimes you have to do the wrong thing. Sometimes you have to make a big mistake to figure out how to make things right. Mistakes are painful, but they're the only way to find out who you really are. I know who I am now. I know what I want. I've got the love of my life, a new heart and I want you guys to get on the next plane out here and meet my girl. Everything's gonna be different now, I promise. From here on out, nothings ever going to be the same. I love you, bye.
