A quick Chicago P.D. flashback: In seasons 1 and 2, "Nadia Decotis" was a 17-year-old prostitute and drug addict. But with the help "Erin Lindsay" (Sophia Bush), she managed to leave that world and enter the Intelligence Unit.

"Nadia" was a very strong person who was always there for "Erin" when she needed support. But in season 2, the world fell apart for "Erin" when "Nadia" was kidnapped, raped, and murdered.

Chicago P.D.: "Nadia Decotis" actress Stella Maeve

Chicago P.D. is thought to have had "Nadia" killed off to establish the high-stakes nature of the new series in the Chicago TV franchise, which has grown increasingly popular over the years and is now airing season 8. But her death left fans heartbroken and greatly influenced "Erin."
