Bailey's plan for getting the residents to stop trying to kill one another is to force them to work together to save a patient's life -- this is the "Gunther" plan. "Gunther," though, doesn't refer to the patient but rather to the doctor who ultimately rises up and acts as leader to make the group work as a team. At first, it looks like it will be Cristina but then she winds up accidentally sticking Alex with epinephrine meant for the patient and he passes out cold. She has to go care for him (and they find out that he has a heart arrhythmia that caused the fainting, so it was ultimately a good thing to learn) and once she's gone Jackson surprises them all by rising up as the Gunther. This makes Mark finally start to respect him a little bit and look forward to them working together, despite the fact that Jackson is still with Lexie.
Teddy gets totally freaked out when Richard moves up Henry's surgery; she's deliriously happy with him and as it turns out she's totally not a cool doctor wife but rather a regular old mess like the rest of us when a loved one is under the knife. Richard finally has to kick her out of the OR when she starts to melt down, but Henry's surgery goes like a dream, with Bailey actually doing the procedure. She had no interest in observing the surgery with all of the Gunther action going on, but Richard insisted and managed to get her to operate on a mouse and then lead the operation on Henry without even realizing it. It turns out that this is so he can put her name on the clinical trial, so that it can move forward when he's dismissed from his job. Knowing that Meredith messed with the trial to help Adele made him desperately want to help her somehow, and ultimately he decides to tell the Board that he's the one who messed with the trial, and that Meredith was just covering for him. When Derek hears this he is aghast but the Chief won't back down, and when the two of them are alone and able to talk freely, Richard basically rips him a new one, asking when he's going to stop punishing his own wife for making one mistake caused by good intentions.
As it turns out, Meredith didn't sneak out of the hospital -- she just snuck to the basement and hid for four hours while Janet and Derek got increasingly angry (Derek) and freaked out (both). She finally contacts Cristina, who is happy to finally be able to implement some sort of plan to help her best friend. She finally sets aside her grudge against Alex to rope him into helping with said plan: Cristina brings Derek and Janet to an exam room where Alex is checking out Zola for some flimsy reason. Meredith says that she got freaked out that something might be wrong and forgot her phone, so she had no idea they were trying to get in touch with her. Alex then gives Zola a clean bill of health. Derek finally decides to go along and at least pretend to not hate Mere but Janet already set wheels in motion after all the morning's lies and so she has to take Zola away while they are re-evaluated as potential parents. Derek goes so far as to tell Janet that Meredith is the best mother in the world, but Zola still has to eventually leave with them. Derek hasn't fully thawed to his wife yet so he takes off too, and it's left to Alex to literally help hold Meredith up without her husband and daughter.
Cristina and Owen, at least, take steps to try and patch up their own relationship. After he has time to think about the lecture he got from Meredith, and sees how Danny loved his wife enough to cut off her leg even after a giant argument, he finally decides to talk to his own wife. He seems ready to accept her for who she is, and he offers to take her to her appointment. She finally breaks down and sobs after all of the stress but then they go, and once there he holds her hand through the procedure.
Episode two starts up immediately, and Mere tells us that when her mother left her father, she didn't tell him what she had done until they were on the other side of the country. "In those days it was called 'family troubles.' Today, it'd be called 'kidnapping.'" While Meredith is off having family troubles, Janet is desperately trying to get a hold of Derek in surgery. A snide nurse replies to Janet's pleas by informing her that everyone thinks they have to talk to the brain surgeon urgently. Her attitude is kind of like the female Derek: humorless and unwilling to help anyone out if it doesn't suit her personally. She finally tells Janet that she'll let her know when Derek calls back.
Bailey and Callie chase down Richard to talk about the Gunther but he's as interested as he was when Bailey tried to bring it up the first time -- he essentially ignores them and tries to talk to Bailey about his clinical trial and some info that he sent her regarding that. He has a surgery later that day to implant another device and wants her to observe, and he's definitely not going to let a Gunther stop her from participating despite her strong protests. Bailey finally gets a word in and explains that the fifth year residents are in danger of actually killing one another or, let's face it, a patient, especially given the earlier surgery mix-up. Richard refuses to let her do it but when she suggests that Callie can supervise, he seems to agree just to get her to stop talking about it. He then reminds Bailey that she has to be there for his surgery at 4.
Teddy finds Cristina sitting in the ER and gets ready to let her have it for sitting down on the job, but Cristina gleefully explains that Bailey paged her 911. Her intern is doing the chest tube instead, "Because it's intern's work." She quickly realizes this isn't what she was supposed to say and she starts sucking up that she's loving this teaching from the ground up but oops, oh well, she has to respond to a 911 page. She's mercifully saved by Henry, who walks up to see his wife. Teddy moans to him about how her good mood has now vanished. Cristina does have a particular gift for sucking the cheerfulness out of a person like a bloodthirsty leech. It turns out his is the islet cell surgery that Richard is doing that afternoon; Richard had an opening and offered it to Henry, who is excited to have his surgery performed earlier than expected. Teddy's obviously thrown off by this development but Henry's so used to surgery that it's nothing, and he tells her he'll call her once he's situated in a room and saunters off as casually as if he's about to go have a beer and watch a football game.
