Hunt stitches up Cristina (I gather she's not trying to out badass him and is numb, since she's totally nonchalant) and she asks him about trauma surgery. He tells her, "Quick and dirty. No time to make things pretty, and no time to make mistakes." He then orders her to drop her pants for a shot -- a comment that, especially on the heels of "quick and dirty" would be really saucy in any scene but this one between two surgeons. She asks if he just doesn't make mistakes, and he answers all macho, "I make mistakes, people die." Cristina admits that she's the best surgical resident in the program, who just killed a man because she didn't know a stitch. Well, technically yes, but I still think that the combination of his other massive injuries played a part as well. Hahn's watching and not helping also played a little part. He tells her that it's not about being the best, it's about saving lives. He then tells her that he makes mistakes and good guys die, but that he learns from that and never makes that mistake again. He tells her that mistakes are how you learn, but she just looks dejected, since we know that she just wants to never, ever make a mistake, period.
Betty wakes up to see her two friends on either side of her. She tells them that her head hurts, and asks what happened. Anna is the one to break the news that Vincent didn't survive the accident, and Izzie just quietly looks up at the clock to watch thirty seconds go by while Betty falls apart. As if there wasn't enough heartbreak for these two already today, Betty then again tells them that her head hurts, and asks what happened. I think that in this single day, Seattle Grace has had more patients die/not be fixed up as good as new than they have during the entire rest of the series combined.
Lexie goes to check on Michael and instead of being a bumbling doofus she is kind and positive, telling him that he's looking strong for his next surgery. Michael clearly wants to say something but can only upward with a look of complete anguish. Fortunately this competent Lexie can guess what he wants to say. She tells him that this happens in life, that people sleep with the wrong people and hide it (okay, George slept with Meredith before he even knew you existed, so this is a bit apples to oranges. But I should stop nitpicking and just let her go on since this is the least annoying she's been all day...) but that she thinks it's what comes afterward that counts, "The part where you make it right. And it looks like you're off to a good start." Sloane has come to the door and heard her as she gives Michael the first tiny look of hope he's had since the accident.
