Speaking of, Mark winces as Callie looks at his still-battered hand and tells him he still can't do surgery that day even though he wants to. They recount the fight and Callie asks him if he's talked to Derek, but Mark protests that Derek threw the first punch, which means he's not reaching out. Callie tries to weakly defend that Mark caught Derek at a bad time but Mark is unsympathetic about his friend losing a patient. "We're surgeons. We're men. We lost patients." He goes on that this doesn't give Derek the right to be an ass, and he can't believe he's now supposed to ask for forgiveness. I agree wholeheartedly about the ass part, and think that maybe Mark should just keep fighting with Derek in hopes that it drives him away completely to somewhere he can be bitchy and condescending to his heart's content while we don't have to watch. Arizona walks by and Callie freaks out and hides, having to explain that she went "all Say Anything" in front of Arizona's date and now she's hiding. When Mark snarks about her maturity, she is able to hit right back with a reminder that he was in a fist fight, so he can't judge. Lexie then walks up and says hi, happily grabbing his hurt hand as she does. As he winces she apologizes for everything, and then reports that Derek isn't doing well and maybe Mark should talk to him? Mark can't believe he's hearing more of this and Lexie leaves.
Izzie dreamily watches Alex be a big boy doctor, and muses about how he's going to be an awesome attending in 10 years. He's totally suspicious but she thinks it should be enough that she just wants to fantasize about her boyfriend and the future. If this weren't television, I might buy that. But Alex doesn't know he's a television character, so he seems to accept it and kisses her. Ryan then runs up to let her know they have something on Patient X so they take off as Mere and Cristina walk up. Cristina is upset that with this new teaching thing Izzie has going, there are no interns to do grunt work. She also points out that while the rest of the residents fight for surgeries, Izzie hasn't picked up a scalpel in recent memory. "She's falling behind. She's the new O'Malley." Alex immediately defends that she is nothing like George, prompting George himself to call, "Helloooooo..." in hopes that they might realize he's there and stop talking about him. Bailey then walks up and assigns George to the clinic, Meredith and Yang with her and Alex to Hunt, despite Cristina's protests that she was supposed to work with her damaged boyfriend that day. Richard then walks up and ignores Bailey completely while he asks Mere if Derek is coming in. She confirms that he is, and then once gone Bailey grabs him to point out that she's been paging him for a while for help on a case. He asks passive-aggressively, "No peds today?" When she says no he grumbles, "Must be slumming." I think that the average emotional age of the entire staff hovers around 13 years old most of the time, but this week it's especially pronounced.
