The chief is on a phone call trying to defend Meredith. Alex walks in and tells the chief he needs to get Meredith her job back. Alex offers to say he lied and wasn't sure of what he had seen. The chief tells Alex this is not on him, but Alex thinks it is. Meanwhile, Sloan continues to mock Avery for a bad stitching job he did on the man whose kid was found at the sinkhole. All of the residents meanwhile are getting paged by Bailey. Bailey is walking around and finally comes upon the woman whose leg was cut off at the sinkhole. She says, "This is a Gunther." She's been looking for one all day. No one knows what it means, except for Callie. Meanwhile, Janet, the social worker, wants to talk to Meredith and Derek together.
Meredith is shown walking urgently. Turns out she's carrying Zola and taking off. Meanwhile, Bailey tells the chief about "The Gunther." She says the fifth-years are at each others' throats. He gives Callie the clearance to do the Gunther. Meanwhile, Henry shows up and tells Teddy he's getting the thing put in. Meanwhile, a nurse tells Derek he's got a call. It's about the baby. Meanwhile, Bailey explains the amputee patient to the fifth-years and tells them not to screw this up. They all rush into the room. Owen comes to the room and sees the scene. He doesn't want any part of the Gunther. Meanwhile, Derek can't get in touch with Meredith. He asks Cristina where she is. Cristina doesn't know. Meanwhile, Teddy is worried about Henry. The chief tells her not to worry about him.
The chief has paged Bailey to spend some time with the mice. Meanwhile, Arizona, Sloan and others watch the fifth-years. Arizona explains the Gunther is a reference to the doctors, not the patient. Whichever of them steps up to lead is the Gunther, which is a reference to the first time this was done and the doctor's name was Gunther. Meanwhile, Teddy sits with Henry before his procedure and gets teary while telling him how much she loves him. He's worried it's a goodbye. Meanwhile, Derek tells Owen that Meredith left with Zola. He's worried about Meredith's erratic behavior. Meanwhile, Sloan watches and calls out Christina as "The Gunther," after she's taken over. Teddy is worried this is the opposite of what Cristina needs. Suddenly, Alex screams in pain then holds up his own bloody hand.
He collapses to the floor. Alex has no pulse while lying on the floor. Cristina is treating him while Avery has taken the lead on the patient. Cristina shocks Alex into consciousness. Meanwhile, Derek talks to his patient the father of the boy from the sinkhole and tells him he can't go see his son just yet. The man starts talking about how his child just slipped away while they were walking down the street. Derek, upset, leaves the room. Arizona apologizes on Derek's behalf, and then tells the man he'll take him to see the boy. Back in the O.R., Sloan finds out Avery is The Gunther. Sloan tells him, "Good job son. I'm right here if you need anything." Meanwhile, Cristina asks Avery how it went with the patient and he says she'll be fine. Teddy walks up and asks Cristina how Alex is.
Cristina starts to make an excuse before coming clean and saying, "I was going too fast and I made a mistake." Meanwhile, Cristina gets a page. She finds Meredith hiding in some dark corner of the hospital. "I think I stole a baby," Meredith says. Cristina starts to try to give Meredith a string of excuses for what she did and why she was AWOL for four hours. Cristina says people make mistakes. She tells Meredith she almost killed Alex in the O.R. Meanwhile, Teddy comes into the chief's O.R. and demands to know why Henry was rushed into the procedure. He tells her to get out of the O.R. Meanwhile, Arizona visits Alex and tells him he needs to go make up with his friends. She says she doesn't want to have to worry about him. Meanwhile, Owen asks Cristina if she wants to talk.
She says she does but she has to go take care of something. She asks him to please believe her. In the chief's O.R. Bailey asks why they're operating on Henry in such a rushed way. He asks Bailey to place the device in. She does. The chief leaves. Meanwhile, Cristina goes to Alex's hospital room and tells him to get up. He screams at her for almost killing him and says she has to forgive him for messing up. She says he's forgiven. Meanwhile, Derek comes to the chief's office to find the chief talking to Jennings, from the hospital board. The chief has told Jennings he was actually the one who tampered with Derek's trial. Meredith was just covering for him. The chief apologizes. Derek just stares at him. After Jennings leaves, Derek asks the chief what the hell he's doing.
The chief tells Derek that Meredith "was trying to save Adele, she was trying to save me. Now when are you going to stop punishing her for that?" Meanwhile, Teddy lies in Henry's hospital bed. They talk about how she was such a mess, "like any ordinary wife would be," when he went into surgery. Meanwhile, Callie finds Bailey and tells her something happened with the chief. Meanwhile, Derek finds Meredith. She immediately says she is sorry. Meanwhile, Bailey goes to see the chief and yells at him for taking the fall for Meredith. She tells him the FDA is not going to want anything to do with him. It's the end of his eyelet cell trial. The chief hands her a binder. He tells her to read it. The artificial pancreas trial now belongs to her. Meanwhile, Alex claims he wanted to check Zola because her white blood cell count seemed abnormal. Meredith says she forgot her phone and had to turn in her pager. As Alex continues to cover for Meredith, Derek buys into the story and plays along for Janet, who was waiting for answers. Meanwhile, Alex apologizes to Meredith, who then talks to Derek.
She tells Derek she just had to take some time with Zola to figure out how everything got so screwed up. She says Derek should take Zola. He tells Meredith she's not fired. The chief is taking the fall for her. Derek tells her to let him protect her, especially if she wants to keep the baby. The husband of the woman who lost her leg goes to her room. They both cry while they talk about everything that happened. Cristina tests Alex's heart. Meanwhile, Avery introduces Bailey to the mice and starts getting her caught up on the trial. The man whose son was found at the sinkhole sits with him. Meanwhile, Meredith sits with Zola while Sloan and Arizona wonder if they could just take the baby away. Owen sees Cristina. They go into the stairwell to talk. He tells her he knows she didn't have the abortion yet.
She says she hasn't changed her mind. Hunt asks her if she's cut off his leg for him. She says she wouldn't botch it like that guy did. He asks when her appointment is. Meanwhile, Janet asks Meredith and Derek about the crazy day they've had. Derek steps up and defends Meredith, saying she loves people so much that she'll do anything for them. She says social services needs time to evaluate their situation. In the meantime, Zola can't stay with them. She gives them a minute to say goodbye. Meanwhile, Cristina sits in place for her abortion. Given one last chance to confirm she's absolutely sure it's what she wants to do, she just closes her eyes and puts her head back.
Owen's eyes water, but he stays by her side while she turns to her. Meanwhile, Derek hugs Zola one last time before Janet comes back in and says it's time to go. Meredith tells Zola that Janet is a nice woman who is going to find her a nice family to stay with for a while. She hands Zola to Janet and tells her some of the things the baby likes. Janet takes Zola and leaves. The episode ends at this point.
