Alex is bouncing a ball angrily against the wall. Olivia comes in and apologizes. She says she wasn't trying to get him in trouble, but McDreamy needed to know. "It doesn't mean you're not a good doctor." Alex says it sure is crappy. They agree that they've both made mistakes. Alex asks if, when they were together, "it" was good. Nurse Olivia says yes, it was; in fact, it was pretty great. And suddenly, as if you didn't see it coming, they're making out. Izzie's gonna be so mad!
Mere is assisting McDreamy on Running Guy's surgery. McDreamy says he thinks Running Guy's going to be fine, then jokes that he and Mere shouldn't try it out for a few weeks, though. Mere: "Funny. You're a funny man." McDreamy says he just didn't know she was dating. Mere says he had to know it would happen eventually. McDreamy says "eventually" feels a lot different than "actually." Mere agrees that it does. McDreamy: "It's surprisingly painful." Mere says it gets better; well, she doesn't really know that, but she's determined to be optimistic. Aw, you two! Just kiss and make up already.
Not so fast. McDreamy finds Addison at the surgery board, and congratulates her on officially signing her contract. Addison chirps that it's time to move forward, then asks him, "We're okay, right?" Lord, if you keep asking him, he's going to remember that he doesn't actually want to be with you, sister, so how about zipping it? McDreamy says they are. Addison's pager goes off; it's Dory. Izzie tells her there's fetal distress. Dory screams that her contractions are really hurting. I'd imagine so. Addison lifts up Dory's drape, and the sheet is covered with blood. Shit. Izzie explains that the placenta's tearing, and Addison says the babies have to come out now. Dory starts to cry, and Izzie consoles her perfectly: "It's okay. We're going to take really good care of you. Just keep breathing." Go, Izzie!
Addison tells Dory that the OR's prepped and ready, and asks where her husband is. He's home with their other three children, obviously. Izzie says they'll call him. Addison tells her to go page everyone on Dory's team, but as she starts to go, Dory grabs Izzie's arm. "No! No!" Addison tells Dory everything will be fine. "Nothing about this is fine! They're too hurt!" cries Dory. Izzie totally takes over with the awesome bedside manner. She tells Dory that she's carried her girls this far, and now it's their turn. "You have to trust us to bring them into the world. Tom's on his way." Addison looks at Izzie with pride and wonder, as she should.
