Cristina and Bailey seem to have calmed themselves with the hugging, because they both look dreamy and need to be told twice by Dixon that they can let her go. Once they do, Dixon composes herself, looking pleased.
Sadie walks up to Izzie like she's going to a funeral, and glumly announces that she has the test results, and... Izzie is anemic. Despite the look on her face I totally figured it was a fake-out and I couldn't get excited that we might get some sort of actual diagnosis and real progression with this excruciating storyline. Izzie is totally relieved but then yells at Sadie for coming to her with that look. Izzie finally asks about the actual patient, and it turns out that is why Sadie looks so down--it looks like she has cancer. Izzie immediately softens and offers to go over with Sadie and tell the woman together.
Lexie walks into an on-call room to meet Mark, who jumps up and rather sweetly grins and says hi. Unfortunately she's about to wipe the smile from his face. She announces with no preamble, like you do on TV when you have something important to say, that she doesn't want to keep secrets. That day alone she kept secrets about Rob's surgery, Derek's proposal, and Mark, and that's the one she doesn't want to keep. She points out that what they have is an actual relationship, and if they are going to continue she wants it to be in front of Meredith and Derek. If it can't be, she adds, then she's not going to continue. Poor Mark looks like someone just shot his dog.
Oh, for the love of little green apples. The piano starts up again and Cristina and Hunt walk in slo-mo towards each other in the hall--she's got her hair up, of course. But this time things end differently than just some secret hand-touching. He sees a blonde woman walk in behind Cristina and speak to someone, and his face falls. He literally runs away, while Cristina stares after him, confused.
