Izzie: I'm a pretty girl.

Chief: What?

Izzie: I'm not being arrogant, it’s just, it’s just kind of a fact. For a long time I made a career from my looks, so I get it, I'm a pretty girl. And not in a "from a certain angle" way, in an obvious way. It’s the blonde thing and the big boobs thing, big boobs are a key to obvious pretty if you know what I'm saying.

Chief: Dr. Stevens.

Izzie: It’s how men see me. I'm not a smart girl or an interesting girl, I'm a pretty girl. The blonde and the boobs it confuses guys into thinking that I'm someone else. And I'm used to it. And I'm used to them walking away when they realize… But then Denny goes and asks me to marry him.

Chief: Is that why you cut the wires?

Izzie: He doesn't make me feel like I'm a pretty girl. He makes me feel like… like me. I think he might know me. And so, if I did cut the LVAD wire, and I'm not saying that I did, but if I did, then no, I don't feel guilty. And I know that I should. And I would if it were anybody else. But I can't feel anything but happy.
