Apparently the residents have their own lounge, and Callie is using it to be depressed and look at paperwork. Bailey comes in to report that Alex is in the clinic. When Callie only mumbles that this is fine, Bailey eggs her on, saying that she knows Callie likes to be told, so she's telling. Callie won't take the bait and continues to study her papers. Bailey, however, seems determined to rile up her superior, and continues to tattle that Alex tried to dump his intern and clearly isn't interested in teaching. It's kind of a strange character turn; I never would have imagined Bailey as a tattletale. And now I've lost any train of thought I had after that statement, because you try saying the word "tattletale" a few times fast. It and everything else will lose all meaning. Callie just thanks her, and after a moment of staring and deciding if she really wants to stop prodding the sleeping dog, Bailey decides to leave for now.
Mark is researching his Dare Surgery, and Derek joins him, eating a Bowl-o-Something. Mark asks if he ever feels old. Derek: "I'm young. I'm a fetus." Mark means does he think eventually new techniques will pass them by, but Derek maintains his genius status. He tells Mark that Mere hasn't told Cristina about them, but that she tells Cristina everything. It's said in a tone that's lighter than air, which clearly means it's the only thing he can think about. Mark's surprised to hear that Derek didn't end it, and then calls him out -- Derek thinks he and Mere will get back together. "You think she's gonna grow up, and get all whole, and want a relationship!" The insight is very Mark, but the use of "get all whole" seems meant for a different character entirely. Derek is smiling like it's a crazy idea, which means Mark is totally right. Mark tells him he's a bad liar; Derek calls him old.
