[Warning: The below contains Major spoilers for the Chicago P.D. Season 12 premiere “Ten Ninety-Nine.”] Intelligence is back at it—and very busy—when Chicago P.D. begins its 12th season, but one member of the unit is noticeably Mia: Burgess (Marina Squerciati). The premiere, however, doesn’t make us wait to find out where she is. Early on, Ruzek (Patrick John Flueger) walks in, having just spoken to her. “She said the conference is good, learning a lot,” he tells Atwater (Laroyce Hawkins). “She’s disturbed by our caseload, so she’s thinking about coming back early.” Martel (Victoria Cartagena), the new detective working with the unit who is killed in the premiere’s final moments (scoop here!), says she shouldn’t, that Cpd loves stuff like that because it gives her a leg up. Fortunately, fans don’t have to wait too long to see Burgess again. Squerciati is back in Episode 3, showrunner Gwen Sigan tells TV Insider.
