The Chief and Mere are on the walkway, and he warmly tells her he hears congratulations are in order. But while he's really happy, she looks taken aback that he knows and her face remains stony as she thanks him and then asks for her assignment. His answer is just, "Dresses." He explains that Izzie has turned her room into a bridal boutique, so Mere's job is to try on dresses with her sick friend, which doesn't seem to thrill Meredith like it would thrill, oh, me. Seriously, if my boss ever tells me, "Your job today is to put on beautiful gowns and be a pretty, pretty princess!" I'm bringing her Best Boss Ever coffee every morning for the rest of the month. Derek must have walked up because from nowhere he pipes up that he thought Mere wasn't wearing a dress. And then the Chief must have walked away, because Mere demands to know how Richard knew they were engaged. Derek gets defensive as he reminds her that Richard is his friend, and then falls into his comfortable, everyday condescension to tell Mere to just talk to Izzie if she doesn't want to wear a dress. Mere whines that she can't do that while Izzie looks at her with, "those cancery, wedding-loving eyes." Derek thinks she's overreacting, but Mere knows her friend well enough to know that they are looking at pink taffeta bridesmaid gowns and Derek in a top hat and morning coat while someone sings "Wind Beneath My Freaking Wings." Derek just patronizingly asks if Mere wants him to talk to Izzie.
Immediately we're treated to a shot of Izzie crying and agreeing to something as she talks to Derek. He walks out of the room and tersely admits that the morning coat is non-negotiable, and that he and Mere have to take ballroom dancing lessons. Mere just widens her eyes in shock instead of doing a little "I told you so" shimmy like I totally would have done.
Callie is doing what appears to be cracking some poor guy's leg bone back into place as she argues with her father. I offer up thanks for the hundred and twenty-second time that Seattle Grace is not a real hospital and that I have never had a doctor act in this manner. As she crunches away down his leg, she insists to her father that she wasn't looking for a relationship, but that this one feels good. Broken Leg Guy appears to pass out but she doesn't notice, still crunching away as she asks her dad when he last saw her admit she was actually happy. The question backfires on Callie, though, as he answers that she was happy when she was home with her parents. Callie laughs that she was 12 at the time but her father is dead serious, and states that he's flying her home that day and will talk to the Chief to arrange everything. She calls after him with a protest but he just happily marches out to do what he has to do.
