Spoilers ahead for the Season 8 finale of Chicago Med, called "Does One Door Close And Another One Open?"
Chicago Med has said goodbye to a surprising number of characters over the past year, and the Season 8 finale added another to that list. Will Halstead has left after eight seasons, making "Does One Door Close And Another One Open?" the swan song for longtime star Nick Gehlfuss. The good doctor resigned after sabotaging OR 2.0 for what he saw as the greater good, and nobody was happy to see him go... but a twist at the last minute guaranteed that there was some sweetness to go with the bitter, and I was left flashing back to an iconic moment from another NBC medical drama: ER. Chicago Med gave Will a farewell worthy of Carol Hathaway!
