Happy from bath-time, Derek comes into the room whistling and cheerfully greets a confused Addison. He maintains that they can be civilized, and she's pleased at the change in his demeanor, even though I'm sure she realizes it's from some variety of naked canoodling with Meredith. They shake on being mature, coexisting adults and co-workers and he realizes she's still wearing her rings, which puts an ever-so-slight strain on the conversation. She unconvincingly says they might be stuck, and he cheerfully suggests using soap. (Did that this weekend when I realized oh so calmly that my Roman coin ring did not fit as it once used to -- thanks for the advice, McDreamy! -- and it worked like a charm. Grey's Anatomy: saving recappers' fingers.) She declares him strange, and he corrects her that he's merely bright and shiny.
In the O'Malley room, Callie is telling the story about when she fixed up George's shoulder and declares that he is "hardcore." Bailey joins them, and O'Malley Senior explains that they're all there but his wife, who is in DC chaperoning a field trip. Callie explains that his clavicle was still hurting, so she upped the meds. Bailey remarks that he's scheduled for his endoscopy later that day. O'Face (Greg Pitts has been in a thousand other things, but will forever be the guy with the O-face from Office Space to me) O'Malley is worried that it sounds dangerous and, unsurprisingly, won't listen to George's explanation: "I didn't ask you, I asked the doctor." Their brother Ronny chimes in to agree, and George mumbles to himself about the white coat meaning that he is a doctor. They blather on and George tells them to shut up, and Bailey gives a warning "O'Malley," at which they all turn towards her and ask what. Everyone is totally amused, and Callie seems delighted to see this unexpected little insight into her ex-boyfriend's life.
