Chicago Med season 5, episode 4 recap: Infection, Part 2

Hunting for clues

That’s not even the weirdest part of all this: Trudy Platt (Amy Morton) meets a guy who recognized one of the victims from a news report. She lived in the infected building and got into a fight over the phone with someone about spraying for bugs.

But Stuart was already sick by then, and besides, Kim Burgess (Marina Squerciati) now thinks he wasn’t the only suspect because those threatening emails they found earlier didn’t really come from him. So who burned the spraying equipment in the building’s furnace? There’s your prime suspect.

While everyone tries to process this new information, Upton meets a teenage girl named Amanda who’s also in quarantine. She tells Amanda the story of how Trudy made her want to become a cop. Danover still finds time to blatantly hit on Will and ask if he’s single despite this huge crisis, too. Priorities, people!

Hank Voight (Jason Beghe) insists on interviewing the apartment building’s residents, even if he has to take Charles with him to do it. He even has the idea to have Upton do some of the interviews from within the quarantine. The residents all confirm there was an exterminator and offer up a vague description. But who can really break the case open? Well, Sharlene, of course! She gives Charles a description of the suspect’s truck.

Chicago Med finally cuts back to the actual medicine, with the lab scientists arriving at the hospital to realize their pet project not only escaped, but mutated. They agree to help with the search for an antibiotic, while Dr. Crockett Marcel (Dominic Rains) is still losing patients.

The last straw is a man named Dennis, who wants to be a firefighter, but won’t be after Marcel has to amputate his infected arm, and then try to console him about it. When the doctor has a moment outside Dennis’s recovery room, that’s the first time Chicago Med fans have gotten to see Marcel show some genuine emotion.
