Mere is watching her quint when McDreamy comes in to check on Lucy's shunt. George runs up in the background, thinks better of it, and runs away. Aw. Mere smiles to herself and asks McDreamy if he's giving up the trailer. McDreamy says he is most definitely not, why, was Addison telling people that he was? Mere says she would never have pegged him for that guy: the marble bath, private pool, gated community...guy. McDreamy: "Don't peg me. I'm not peggable." I beg to differ. Mere's quint starts to crash, and McDreamy, George (who must have been lurking outside), and a nurse run over. Her lung has collapsed. McDreamy hands Mere a needle, and tells her to stick it between the baby's ribs. She does, there's a gush of air, and...all better! George stands watching them in disgust. Heh. McDreamy tells Mere nice job, and adds, "I'm not giving up the trailer." Mere giggles, "Whatever you say, Dr. Shepherd."
Cut to Mere explaining to Dory and Tom what happened. She says it sounds scary, but really not that uncommon in a preemie this size. Dory has her back turned to Mere, and her head drops lower as Mere explains that they inserted a tube in Charlotte's chest to help her breathe. Mere tries to assure Dory that the baby really is doing fine now. Tom's phone rings, and he says he has to go, because his mom can only handle the triplets for a little while. He leans down and tells Dory he'll call as soon as he gets home. Dory is unresponsive. Mere tells Tom she'll keep an eye on his wife. Snap out of it, Dory! It's just quintuplets! Mere walks over and tells Dory that she can't blame herself for this. Dory says she's got one baby who can barely breathe, one with half a heart, two other sick ones, and if she'd listened to the doctors, she could have three healthy girls instead of four who might not live until tomorrow. "It was my decision. Tom agreed with the doctors. So, really, Dr. Grey, who else should I blame?"
Burke is quizzing Izzie before Emily's surgery. I don't know what he's talking about, but Izzie correctly answers, "Stenosis and atresia of the mitral and aortic valves." Burke asks another question, which Izzie also answers perfectly. Burke is impressed that she's done her homework. Izzie says she studies when she's on call. Burke says no matter what the books say, he guarantees she's never seen a heart this small. Izzie catches sight of Alex outside the room, and says to herself, "Betcha I have." I don't know what Izzie's so upset about, since she's about to spend a few hours just inches away from the way hotter Burke, but to each her really dumb own, I guess.
