A woman with a baby comes in to the ED. She tripped holding her baby. Baby is unresponsive. But when they open the blanket, there's a doll in it, not a real baby. The woman insists her baby needs help.

Sharon comes to see a very depressed Dr. Charles. She says there's a situation in the ED and Charles hasn't responded to his pages. She asks what's wrong. The judge has ruled that Susan can take his daughter to Arizona. Sharon is sorry but she is sure Charles can still be part of Anna's life. She will get someone else to see the patient. Charles says work will take his mind off this.

Dean is impressed that they have an OR in the ED. April says that Ethan makes his bed every morning because of Dean. After some awkward conversation, April sets up a room. Dean makes a statement to Ethan about how nice it is that the nurses here don't have to do both bugs and pus.

He wants Nat to be happy.

Dean shadows while Ethan sees a patient with pancreatitis. Dean interrupts to finish the explanation of what's wrong with him.

No evidence of stroke or other brain damage. But there is a fracture pattern in the patient's brain. She might have fallen a year ago.

Nat tells Carol that her surgery has been scheduled. Carol goes on and on about how great Will is. Nat tries to tell her they moved on and she saw someone new: Dr. Marcel. Carol said OMG I put my foot in my mouth. Carol tells her not to introduce him to Owen and let Owen get too attached. Carol wants what's best for her, especially now that she doesn't know how much longer she's got. Nat says she will be happy and Carol will be fine.

Ethan has got tests back too. His guy has a pancreatic abscess. Dean disagrees with Ethan's treatment plan. He wants to drain the abscess himself.  Ethan agrees.

Will finds Nat crying. The chances of a heart transplant are so slim so Carol probably only has two years. Will says you might have more time than you think. Carol is an ideal candidate for his clinical trial. Nat says but it's experimental. And what if she doesn't get the drug? It might b. Nat te too late after a few months. Will says if you want time, the trial is the best option. Nat thinks Will should present it to her mom.

Anna does not want to leave Chicago. She does not want to leave Charles.  They are interrupted by Maggie and Anna hangs up.

Maggie has found the woman's ex. The accident happened a year ago. He couldn't let them do surgery on a tiny baby. Sarah died and when his wife woke up she was so angry it destroyed the marriage. He knew the doll was a bad idea. Charles thinks the doll has become his wife's attempt to rewrite the past and make Sarah alive again. He has an idea but they need her ex's help.

Ethan's patient is crashing. Dean thinks taking him to surgery is not a good idea. He says he will walk Ethan through a procedure that is minimally invasive.

Auggie is talking about Keishon. He asks Maggie does he really have to go back tonight? Maggie is sorry. Maybe Auggie can visit him in California soon. Auggie seems unhappy with that.

Nat is sorry she didn't tell Marcel. He tells her that he's worried that Carol's affection for Will is clouding her judgment, and maybe Nat's. Nat says she would never let her feelings cloud her judgment. She wants her mom to recover. Marcel says she has to see this as a gamble. He just wants her to be prepared for all the outcomes.

Ethan and April disagree about whether Dean made the right call. Does Dean know he's not Ethan's superior anymore?

Sarah and her husband grieve over the doll. Maggie is watching. Sharon asks her what's going on. Maggie says she's saying goodbye to her baby. She can't stand this and goes.

Maggie goes to the stairwell. Sharon meets her there. Maggie tells her how the Carters want Auggie. She can't lose another child. Sharon says another? Maggie has never told anyone except Ben that when she was 16 she got pregnant so she put the baby up for adoption and after she was born she held her and the nurse took her away. Her friends all thought she'd make a great mom and she couldn't tell anyone. She didn't think she deserved to be a mother and then Auggie came into her life. She felt like it was a second chance. But he was so happy with his brother. What does she do? Sharon tells her what she did for her baby was love and whatever decision she makes will come from that place.

Charles tries to talk to Susan who thinks Charles is the good cop and she's the bad cop. Charles says it's not that simple. Susan is super defensive and accuses him of playing head games. He tells her that Anna was pregnant and didn't want her mother to know. Susan calls him a manipulative SOB.

Dean says so you're checking my work? Ethan tells Dean that in this ED he's in charge, not Dean. Dean says he was just trying to make a good impression. He understands he needs to follow.

Marcel has done the surgery on Carol. Nat wants to stay with Carol. Marcel offers to stay with her. She accepts.
