Chicago Med Season 2 Spoilers

The cardiothoracic surgery fellow's new boss Dr. Latham (Elementary's Ato Essandoh) is "a very different personality" from his late mentor, executive producer Andrew Schneider says. "Where Downey was such a nurturing, parental figure, this guy is distant emotionally and very hard to read, but a great surgeon." As a result, Connor is "really thrown into the fire this season," EP Diane Frolov adds. "He's really confronted with what he doesn't know."

The doc will try to move on, romantically, with pathologist Nina Shore (Colin Donnell's real-life wife, Patti Murin). "She's great, they have a very good relationship, but Will can never quite get rid of his feelings for Natalie," Schneider says.

The former firefighter is "a very different kind of med student," Frolov says. "He has a lot of experience in the field as a fireman and an Army Ranger. So he loves to jump in. He's used to commanding people. He wants to get involved right away, and that rubs up against Will, who is now the attending, who has to go by the books."

"Jeff and Natalie are very attracted to each other, and they start up a romance," Frolov reveals. "It causes a lot of drama in the ED." On the medical front, viewers will meet a recurring patient, a little girl with cancer whom "Natalie has been treating for some time," per Schneider.

The newly-minted chief resident gets involved in a program "where the Navy sends corpsmen to Chicago [to] experience taking care of people with gunshot wounds," Frolov shares. "There's so many gunshot victims in Chicago that they can see that more [in the city] than they do even on the battlefield. This a real program."

The shrink will not be thrilled when his epidemiologist daughter Robin (90210's Mekia Cox) strikes up a romance with Connor. "He knows about Connor's family life, that Connor comes from a very dysfunctional family, and you want your kid to be with someone who's experienced a happy family life," Frolov describes. "Charles, himself, created a bit of a dysfunctional family life for his daughter. So he has mixed feelings."

In the season opener, the nurse is "really avoiding Tate and his son because of her fear about giving TB to them even though she is latent," Frolov previews. "She has to be really convinced that she's not contagious and can continue with her life. But then as she does so, her TB ceases to be latent and becomes active."

"We've got big plans for Sarah," Schneider says. After Dr. Charles taps her for a psych residency, "she's going to have a huge learning curve, because she never in her wildest dreams imagined herself as a psychiatrist. But he has every confidence that she will be a great shrink and is now really her mentor."

After the demise of her marriage, Goodwin "will grieve, but she's going to get a hold of it," Frolov previews. "She's going to move in a different direction with her life."

In Season 2, much will be revealed about Maggie, especially when her family comes into the picture. She has "a complex relationship with her sister," Schneider says. Adds Frolov: "We find out about her mother."
