Derek is staring at a scan of Archer's brain with eight little bright spots in it. Sam comes in and announces, "Your wife's in the chapel, praying." Good God, you guys, how much ruder could you be about not letting Derek and Addie's relationship just be over? Especially since you yourselves are divorced? Derek informs Sam that she isn't his wife and she doesn't pray (heh) but gets up and happily hugs his friend. He asks Sam how he is and Sam admits to a midlife crisis that resulted in him getting his ear pierced for a day until he realized how dumb that was. He then tells Derek that he met Mere, and gives his buddy a friendly, "way to go" punch in the shoulder. Derek tells him kindly but firmly, "She's not a midlife crisis. She's the real thing." Look at him, acting mature and standing up for his girlfriend. If he could just cut out the condescending bullshit when he's talking to her, he'd be in the ballpark of the McDreamy of yore. Sam says he's happy for Derek, and seems to mean it and doesn't again bring up anything more about him and Addison, so for now he's better-mannered than Naomi. They apologize to each other for not calling, admit they've all changed, etc. but Sam comes back to Addison and the praying. Derek admits, "She's expecting a miracle," but he can't do it for her. He tells Sam about the 8 cysts, and Sam suggests that maybe he's too close to the situation, and offers another idea -- how would he take care of just one? Derek begins to explain it.

Sadie rips a cuff off of Rob's arm as Izzie and Alex watch, and I'm stunned that she seemed to actually get something right as she announces his blood pressure. He asks the residents what the prize is for winning, and Jen adds that they need a prize. Izzie assures them there is a big prize, then leans over and tells Alex they need a prize. Ah, writing cliché #143 this hour. Mere comes in and asks what's going on as Sadie starts an ultrasound on Jen, and Alex explains that Jen and Rob needed a distraction, and Izzie needed real patients for the contest. Izzie is still a little bit over-excited about how much fun this all is. Jen asks when her surgery will be and Mere assures her it could be any time now. But first, Jen's in for a horrible shock when Sadie puts on her "bad news" face and says that she can't find a heartbeat. Alex is there in a flash to announce she's on the baby's butt, and finds the beating heart much to Jen's relief. Izzie claps maniacally at Sadie to try and lift her spirits, which just makes Sadie madder and Izzie look all the more insane. I do like the nod towards Alex and his good touch with moms and babies, which has basically been forgotten since Addison left and the writers got tired of that storyline.
