Are Severide's (Taylor Kinney) womanizing ways coming to an end on Chicago Fire?

On the 100th episode, which airs Tuesday, Severide is starting to re-evaluate his priorities. And a surprising revelation from his former colleague (and now Chicago Med character) Jeff Clarke (Jeff Hephner) couldn't come at a better time.

"We've done four-and-a-half seasons where Severide has definitely been ... an emotionally free spirit, I would say," executive producer Derek Haas tells TVGuide.com. "He doesn't get too encumbered with the people who come in and out of his life. ... Now he's in his mid-30s and he's trying to figure out what he's going to do with the rest of his life."
