Spoilers ahead for the Season 8 finale of Chicago Med on NBC.
One Chicago often delivers game-changers in season finales, and Chicago Med is guaranteed to be a very different show when Season 9 premieres due to the departure of Nick Gehlfuss as Dr. Will Halstead. After breaking bigger rules than usual to sabotage OR 2.0, Will turned in his letter of resignation, said some goodbyes to his coworkers, and left Chicago... only to arrive in Seattle for a surprise reunion with Torrey DeVitto's Natalie Manning! In the wake of the finale (available streaming via Peacock Premium subscription), the actor shared his thoughts on the Manstead reunion as part of Will's goodbye.
