What Happened to Jo on ‘Chicago Med’ Season 8?

During Season 7, Dr. Scott treated patient Melina “Jo” Jovanovic (Riley Voelkel) but suspected she was a drug dealer because of her speedy exit from the hospital. However, Dr. Scott soon discovered that Jo was an undercover cop when she showed up at his apartment seeking medical treatment shortly thereafter.

After learning that Jo was working on a Serbian mob case, Dr. Scott offered to help. In fact, he even asked Dr. Will Halstead if Jo could hide undercover in their apartment. While the two worked together on the case, they became romantically involved, but it quickly came to an end during a fatal altercation in the Season 7 finale.
