Chicago Med Season 12 Episode 6 photos show Dr. Caitlin Lenox back with Dr. Mitch Ripley in “Lessons in Chemistry,” premiering tonight, Wednesday, November 11, at 8 p.m. ET/PT on NBC. Ripley evaluates a patient suspected in a murder from decades ago, while a decision forces Dr. Daniel Charles to reckon with painful family memories.
Sarah Ramos returns as Lenox alongside Luke Mitchell as Ripley and Oliver Platt as Charles. The stills also feature Rebecca Breeds as Mallory Sloan, Jessy Schram as Dr. Hannah Asher, and Darren Barnet as Dr. John Frost.
What Is “Lessons in Chemistry” About?
Ripley’s patient comes with questions that reach well beyond the exam room. The episode listing identifies the patient as a suspect in an old murder but leaves the circumstances of the crime open. Charles faces a separate choice as he revisits his own family’s past.
The gallery pairs Ripley with Lenox, Mallory and Asher in separate shots. It also shows Frost with Dr. Annie Wu (An-Li Bogan) and Wu with Imogen (Iman Benson).
