Baptism by Fire brought about a season 12 first for Chicago Med—the show featured the first full-on One Chicago crossover of the season, as Trudy Platt arrived to investigate a cold case.
While each One Chicago show has featured a brief cameo from another member of the cast—Dean Archer has shown up on Chicago Fire this season, for instance—this is the first time in the 2026-2027 season that someone from another cast has been given a meaty role on a show where they’re not a regular. And Trudy definitely takes advantage of her time as the center of attention, with a startling mystery that features Sharon Goodwin.
Med definitely gave Trudy more to do in a single episode than she’s had to do all season on PD—to be accurate, she did more in this episode than she has on multiple seasons of PD. During the episode, three women who had been held hostage in a bunker lit their place of entrapment on fire. They were injured and were treated at Gaffney. Trudy showed up to investigate their plight, and her belief that the incident was connected to an old cold case she was never able to solve is proved to be right.
It turns out that Trudy’s missing person case connects to a young, injured boy picked up by Wu earlier in the day. The boy turns out to be Max—child of the women’s captors, Esther and Clark. Esther turns out to be Missy, one of Clark’s original kidnapping victims and the missing person that Trudy had been trying to track down. Though Trudy tries to talk Missy/Esther back into her own head, Esther can’t handle the weight of what’s happened or the memories she’s repressed and runs into traffic to avoid accountability.
While the doctors work to save Missy’s life, a crisis develops with one of the wives, who has been drugged by Esther and Clark. Missy survives her injuries and eventually ends up telling Wu what they drugged the wife with, saving her life. Trudy ultimately leads a press conference about the incident, then joins Sharon at the burnt-out shelter where the women were being kept hostage. The two women take a breath and consider the scope of the case as the sun shines in. It’s a great moment for Trudy—and though it didn’t take place on the mothership show, it’s one of the best cases she’s dealt with in a long time.
