Callie walks in to the OR to ask what happened and Teddy just angrily orders a nurse to show Callie a tray. Callie looks inside and sees a screw caked with gore, and as she stares uncomprehendingly Teddy spits that the screw was ripping into Laura's cardiac muscle each time her heart tried to beat and now her heart looks like hamburger. Callie is horrified, and when Teddy demands to know what happened, Callie has no answer.
Back in the ambulance, Meredith and Derek have both slumped back into their seats and look exactly like they did on the way in. Alex won't let the baby subject drop and suggests adopting again -- Meredith points out that as social services just took their baby away this would probably not work out for them. Alex keeps suggesting other options and ignoring Mere's pleas to stop, telling her that she can't just give up. But when Mere tells him thanks but it's not his business, he retorts sadly that it is because it's all his fault and he can't handle it. Mere tells him it's not but he's sure it is and seems sincerely tortured and not just saying it so have Mere absolves him of his guilt. They argue about whose fault it is and Mere points out that what Alex did was dirty, but what she did was in fact illegal. Their conversation is interrupted when there's a big bang, the ambulance comes to a stop and the siren slows down and quiets. Alex calls up to the driver to ask what the problem is.
Avery gets pulled out of surgery by an absolutely livid Callie, who whisper-yells at him that after the surgery he performed (oooooooooh) (though, she did supervise) to put screws in Laura's spine has gone horribly wrong since one of those screws was stabbing her in the heart. She informs him that Laura is half-dead now and they get to go tell her husband that.
