Sloane sidles up to the nurses' station and gives Olivia a sexy hello. She demands that he not smile at her and another nurse joins them, adding not to smile at either of them. Turns out they've talked and compared notes, pickup lines, and even technique. Mark asks questioningly, "'Technique'?" In unison, they tell him, "Identical." Olivia does get around a bit, but with the exception of George, I say very, very well done, my friend. They inform Mark that they've formed a club, "Nurses United Against Mark Sloane." After a beat Mark smoothly asks if there are any club activities, which drives them away in a huff. Derek walks up, but before Mark can tell him about the club, Derek tells him a boy has been looking for him. He steps aside, and the little boy (whose name is Ryan, which I don't think is ever actually mentioned, but which I learned on the internets and therefore will use for recapping purposes) looks up at Mark and hopefully asks, "Daddy?" Mark is more scared than I'd guess he's ever been in his life, and at the look of abject terror on his face, Derek laughs and hands Ryan a twenty. Mark, still scared, yells that he'll get Derek back, and then looks back at Ryan. Ryan announces that Mark's not his dad, but he is hoping that he'll build him some ears.
In the clinic or the ER, I can't tell which, a nurse runs by Alex and tells him someone has requested him in Curtain 3. While they walk there, Norm says he's not feeling well and that he thought he'd head home. Alex gives him a bunch of shit about how surgeons have to work through all that stuff and pretty much dares him to stay, and then pulls the curtain back to reveal...Ava. Norm begins to explain how he's not feeling well, but Alex shoos him away and pulls the curtain back around. A husband she doesn't want and a town she doesn't want to be in seem to be agreeing with her, as Ava looks absolutely fantastic. By way of greeting, she tells Alex about how all the moms in town dress up, so she thought about what she might want to be. Can you guess what that is? The only thing she wants to be for Halloween is Ava. Alex shows her how much he likes that idea by grabbing her into a kiss.
Mark and Ryan are in the lounge, and Mere walks in and asks what's up. Papers are all over the table, and it turns out that they are notes to Mark from all the kids in Ryan's class. He explains that Ryan has the internal structure for hearing, but no canal or external structure. Aaaah, so that's what the headband is -- it's a hearing device. Even though Ryan said he wanted ears, I still couldn't see enough of him face-on to quite get what he meant. Ryan adds that he thought if he came in with all the letters, Sloane would feel sorry for him and do the surgery for free. Mark claims he'd like to help, but Ryan interrupts his excuse to add that on his way there that day, three different people asked if he was in costume, since he looks like a permanent Halloween costume. "Just thought you should know that." Meredith admiringly tells him, "You're good." Mark still hesitates, explaining that a pro bono surgery means they'd also need an OR, anesthesiologist, general surgeon, and scrub nurses among others. He says he can't ask for the help because he has no social capital -- evidenced by the fact that the nurses have formed a club about hating him -- and that he can't ask for favors since he never does favors for anyone else. The thing I enjoy about Mark is at least he's self-aware enough to admit to all this, even when it's a time like now where his overinflated ego isn't necessarily very attractive. He adds that he would do it if he could. Meredith, however, has an idea and tells him that she's got social capital, or at least her mom did, and her mom was really big on pro bono work. Mark cuts a deal: if Mere can get everything and everyone they need, he's in. He leaves, and Ryan turns to Meredith with one question. "These people who knew your mother. Do they know you brought her to work in a baggie?" I'd like to request that Ryan replace Izzie on the show from here on out.
