Sheffield — who makes his debut in Episode 6 — enters Firehouse 51 after the beloved Chaplain Orlovsky (played by Gordon Clapp) announces his retirement. He is described as a “warm, kind-hearted, clean-whistle, open and eager” clergyman. The born leader has a caring soul, and speaks with affection and authority. While the character is a fresh face to viewers, the audience will discover that Sheffield already shares a history with new paramedic Emily Foster, who joined the team in the Season 7 premiere. He will also interact with Emily’s partner Sylvie Brett.
In addition to his season-long role as Jay Garrick/Zoom on The Flash, Sears’ TV credits include 24: Legacy, Masters of Sex and 666 Park Avenue, as well as a Season 2 episode of Timeless.
Chicago Fire airs Wednesdays at 9/8c on NBC — except for next week, when the series temporarily shifts to 8 pm for the #OneChicago franchise’s three-show crossover event.
