55 18 "So Long, Dawn Long" Vanessa Parise Andrew Chapman & Nate O'Mahoney March 17, 2020 3LAP18 4.77[74]
Dawn Long, the patient from the "mother of all surgeries," is brought back to Chastain after getting sick. Upon discovering that it has been six months, Cain chooses to finally remove the brain dead Dawn from life support as her statistics will no longer be tracked and to everyone the surgery will have been a success. Before Dawn's family allows her to die, Cain secretly orders tests to determine the source of her illness, circumventing Conrad and Devon. As Bell's new talk show grows more popular, he is removed from the surgical schedule by Logan Kim, but is called in by AJ to help save Bill Landry, the owner of Georgia FC, in a marathon surgery. Conrad and Nic help Kit Voss treat her son-in-law Derek who is discovered to have cancer with a fifty percent survival rate; despite chemotherapy complications, he makes it through the night thanks to his medical student wife. At the end of the episode, Cain receives a call revealing that Dawn Long was infected with candida auris, a dangerous superbug, one that is almost impossible to remove from a building once it spreads. As Cain rushes to spread the word, the people cleaning her room become exposed and her contaminated ventilator is moved into a storage room with multiple other ventilators, possibly contaminating them as well.

Note: The episode begins with a title card stating that while the episode is relevant with the coronavirus pandemic, it was written and conceived months before and superbugs of all kinds existed then as now and any relationship to current events is coincidental. The title card also announces support for hospital staff and first responders that risk their lives on a daily basis.

Cain and Kim attempt to contain the candida auris contamination while covering up its existence; after Conrad and Devon's patient Sophia, an EMT, is possibly exposed, Cain discreetly enlists Ezra's help to treat her having been threatened by Kim into keeping silent despite Cain's desire to come forward. Conrad figures it out on his own and Cain confesses to Ezra that as an intern he didn't speak up, costing four patients their lives before Red Rock and Ezra's mother intervened to save him; Ezra reluctantly helps Cain cover up the mistake with Sophia but comes clean after Sophia dies. Conrad confronts Cain who is left guilt-ridden over his inaction when coming clean earlier may have saved Sophia's life. Nic and AJ treat Isaac, a young man who requires a lung transplant, but lacks any sort of support system; the two help Isaac find what is potentially his biological family who agree to support him either way. With Derek's condition deteriorating, he requires a ventilator and gets Dawn Long's still-contaminated one.
