SPOILER ALERT: This article contains spoilers from the Wednesday, Oct. 1 episode of “Chicago Med.”
Big news for fans of “Chicago Med”: Hannah Asher (played by Jessy Schram) and Dean Archer (portrayed by Steven Weber) are expecting a baby. The Season 11 premiere kicks off right after the dramatic Season 10 finale, with Hannah arriving at Dean’s doorstep to reveal the joyful news that he is the father.
Throughout the past five seasons, Hannah and Dean have shared a flirtatious chemistry, but they had never acted on it, primarily due to her tumultuous relationship with Ripley (Luke Mitchell). The season finale left viewers in suspense over whether Ripley or Dean could be the father, but showrunner Allen MacDonald confirmed there was a potential third candidate, adding rich layers to the narrative.
“In this scenario, we had three possible fathers: Ripley, Archer, and a third, which we joked could have been Will Halstead,” MacDonald told Variety. “That would have marked the first appearance of Will Halstead in quite some time.”
Nick Gehlfuss, who played Dr. Halstead for eight years before his departure from the show in 2023, will return in the second episode but not in connection to Hannah’s pregnancy. Instead, fans will see an update regarding his relationship with Natalie (Torrey DeVitto) while he returns to Chicago with their son, Owen.

Ultimately, the choice to make Dean the father was driven by the potential for intriguing storytelling, as both characters have evolved significantly throughout the series. As MacDonald explains, their relationship took a turn during the Season 10 episode titled “The Book of Archer”, where they shared an intimate moment.
“Both Jesse and Steven portrayed the aftermath beautifully. It’s reminiscent of ‘The Sixth Sense’ where, in hindsight, everything falls into place,” MacDonald reflects. He notes that while audiences have never witnessed the two kiss, their bond has always been marked by an unspoken tension.
Showrunner MacDonald also decided not to depict the night of their union through flashbacks, opting to keep it a surprise for viewers. He states, “As a fan, I would have loved to see it too, but we wanted to focus on the shock when Hannah knocks on Dean’s door and announces her pregnancy.”
Weber acknowledges the complexity of their relationship, saying, “I don’t think anyone wants to see that right now, but there’s a full season ahead, and the path will be filled with ups and downs. Any display of affection will be meaningful and reflective of the unique journey they’ve had together.”
The ramifications of Hannah’s unexpected pregnancy create a host of questions about the future of their relationship. MacDonald emphasizes that their dynamic is about to shift dramatically: “How will this change their friendship? Will they remain on good terms? Will it lead to tension? Their feelings are going to be tested.”
This storyline marks a significant moment in the “One Chicago” franchise, as it evolves beyond traditional portrayals of pregnancy—most often involving tragedies—toward a more hopeful arc.
MacDonald highlights the challenges of portraying a pregnancy on screen, stating, “It requires a commitment from Jesse, as she’ll need to wear a prosthetic that will increase in size throughout the season. It’s demanding, but both she and I feel it’s an essential narrative to explore.”
Tune in to “Chicago Med,” produced by Universal Television and Wolf Entertainment, airing on NBC Wednesdays at 8 p.m. ET for more incredible developments as the season unfolds.
