We pick up where we left off, with Fire coming to the rescue as the apartment building burns. Lots of smoke and the fire explodes as the first responders are trying to get people out.

Hannah insists she is okay. Will thought she had got out. All the doctors seem to be okay. Scott decides he has to try to find Milana.

At Med, Archer takes charge, working on the patient who was shot during the fire. Meanwhile Scott is running around the area calling for Jo. She's in a dumpster or something, shot. He wants to get her to the hospital. She says it's not his fault. He tells her she will be okay as he calls it in.

Will tries to convince Hannah to take a few hours to relax. She won't. Will fills ner in that Milana is not looking great. Will tells Maggie he has no clothes for his testimony today now.

Milana is crashing. Marcel works on her while Will and Scott watch. No pulse. Scott is begging Marcel to open her chest as she flatlines. Scott refuses to give up and begs her to come back. Marcel tells him they lost her. Sharon is sorry. Scott runs off, past Charles.

Charles comes to see Scott, who says it was his fault. Charles tells him he was trying to protect Jo and himself. Scott cries that he killed the woman he loves.

Abrams tells Marcel that Pamela is angry and that she is going to a rehab in Boston. He also thinks Marcel made the wrong decision on purpose so he could become Chief of Transplant and one up Abrams.

Marcel asks Sharon not to be on the transplant team anymore.  Sharon says they put a lot of time and money into his training and the answer is no. She says she knows about Blake's surgery and she is sure he wants to atone, but it would cost too much to replace him and they can't turn away patients because of lack of transplant doctors.

Fire and PD say that the fire was set deliberately. They'll know more after looking at CCTV. Scott tries to blame himself. Will says that he is fine.

The shot bad guy might die. Scott wants to donate but his blood type is wrong.

Sharon goes to talk to Charles, who forgot all about his breakfast burrito. He's got Scott on his mind. Scott was in love with Milana. Sharon asks him whether he's found another therapist. He asks about the trial instead.

Vanessa has brought Grant to Med. Maggie declines an offer of coffee with them on this sad day.

Scott asks his dad to help him get in touch with narcotics.

Archer sees a patient who is super paranoid after smoking weed laced with fentanyl. The patient is difficult because of his paranoid state. Archer ahs Charles paged.

Hannah has trouble breathing all of a sudden and Will calls for Ethan. Ethan says he got this but Will insists on staying (no one is listening to anyone apparently). Hannah refuses intubation and it's a mystery why she suddenly can't breathe. Ethan tells Will he has to back off because Hannah is Will's ex.

David's parents are shocked that psychiatrists are there. His father insists he doesn't need a shrink. David refuses to eat his food because it's poisoned. His dad starts yelling at him. Charles says he understands this is uncomfortable for David and they will get him out ASAP. He introduces Dr Chavez, his new resident, to Archer, who is condescending as usual. Anyway, the question is whether David's psychosis is drug-induced or not.

Hannah has interstitial disease. Choi wants to do a biopsy. Suddenly Hannah's oxygen sat level drops. Choi is angry they didn't intubate her earlier.

David's father says this behavior is out of character. David is a perfect kid until recently. His grades have dropped off and he seems off in his own world, alone in his room. The parents don't know if he has any friends. The father says lots of kids are loners because of COVID.  But he has noticed David is up late at night, but that's all normal teenage stuff, right? Charles asks for permission to examine David again. The parents agree.

Scott has tracked down a donor, Kosovich's brother. Marcel explains that this is a complicated procedure. Brother wants to do it.  Marcel says Scott will prep him.

Choi has gotten the biopsy. Talc particles in her lungs from when she was using heroin. The smoke last night triggered breathing problems as a result. She is on Steroids now.

Grant has texted Maggie. He wants to know if she is uncomfortable because of him. He wonders what would have happened if they'd been together all these years. Maggie cuts that off. She's married. He needs to move on.

Sharon tells Marcel they have a shortage of blood. They can't use more than 7 units. Marcel says he needs the blood.  Sharon is sorry.

David refuses to talk to Charles. Finally he says Dad said the pot was bad. He says people are stupid but won't talk about if he was alone when he smoked it.  David talks aloud to an invisible person but denies seeing the hallucinations and claims he's not crazy. Charles says sometimes he gets confused when he hears his inner voice. David admits he has a voice that tells him to do things, that tells him not to trust Charles. Is something wrong with him? Charles says they will figure it out.

Charles' assistant says we know what's going on. Charles says the parents have to give consent so let's hope she was observing the too.

The supervising surgeon says holler if you need me. The patient needs more blood but there isn't any.  Marcel says they have to close now. Scott insists he call Dr. Jones and that he can't stop the surgery. Marcel has he has no choice.

Archer tells Charles that the psych fellow is looking for him. He says Dr. Cuavez is taking too much satisfaction in putting a label to the behavior. He's pretty sure David has schizophrenia. He hasn't told the parents yet. Archer says he tried to call his son yesterday. He lost him to drugs 15 years ago and they don't talk. Charles is sorry to hear that. Archer says the point is he knows what it is going to be like for these parents. They will not understand how this could happen. Charles says he has to tell the parents now. He hopes they can get David the help he needs.

The patient has stopped bleeding. The supervisor praises Marcel.

The father still thinks this is normal adolescent stuff. The doctors gently explain that David is suffering from an illness. The parents don't understand why he needs to see another psychiatrist. Charles explains that they think David has schizoaffective disorder. The parents won't believe it and insist their boy isn't crazy and they want nothing to do with them and want to take David home now. Charles tells his fellow that sadly the reaction is not uncommon, but it means David won't get help.

Scott comes to see Sharon and says that Goren's transplant is going well. Sharon has to go to the trial. Scott says he's leaving Med because he doesn't think he can escape his past as a cop here. He has to go someplace where he can just be a doctor. Sharon says she will miss him. He says he met and lost Jo here so...

Will gives Hannah the news. She says she can't shake the past. Will assures her she's not in this alone. Sharon interrupts to get Will for court.

Peter is not impressed with Will's borrowed suit. Meanwhile Jess is arrested for setting the fire and attempting to murder Will. Will looks upset.

Marcel comes to see Blake even though she doesn't want to see him. He says he came to thank her for what she taught him and that he has an obligation to continue this work. She says nice speech, but she's sidelined. When she comes back, she doesn't want him on her team. Marcel says she would have made the same call if their roles were reversed.  He goes.

Charles talks to a therapist who is busy on the computer and wants to do his intake by the book and asks in what way was it difficult today? Charles has left.

Choi runs into April. She saw his dad's obituary and she wasn't sure Ethan wanted her at the service. He asks if she's back. She says yes she is. She finished her program. Choi says he is better pretty much. She hopes he didn't get married. She didn't either. She says she'll see him around.

Archer gets a phone call from Cook County Jail. Collect from his son.  Meanwhile, Maggie sees Vanessa and Grant laughing together.

Will catches up with Dylan and tells him Goren did not start the fire. He hopes Dylan's decision didn't have to do with the fire.  Will encourages Dylan to rethink leaving. Dylan tells him to take care and goes.
