You may have heard that Yaya DaCosta (Whitney) will be playing Maggie Seaver, a nurse who romances Severide (Taylor Kinney) on Chicago Fire as part of the backdoor pilot for Chicago Med. But this relationship won't be like any other romantic entanglement Severide has had before.

"We initially wanted to go with a dynamic that wasn't the typical Severide thing : He meets a girl, she bats her eyelashes, says when and where... and they're off to the races," executive producer Matt Olmstead tells TVGuide.com. "He shows up and her initial reaction is, 'You suck. Get away from me."

That's because the pair actually went to high school together — but they definitely weren't sweethearts. "She did a real favor for him when his parents were going through a divorce and her family looked out for him," Olmstead says. "He never got to thank her."

"It's a strange similarity to his relationship with Shay," he says.
