Chili replaces Peter Mills (Charlie Barnett), who left to be with his family in North Carolina in the previous episode. Partnered with Sylvie Brett (Kara Killmer), Chili doesn't exactly get the warmest welcome from the firehouse when she's introduced in Tuesday's episode. She'll remain on the NBC drama for the last three episodes of the season.
Burge, who played Becky on Friday Night Lights' final two seasons, most recently appeared on NCIS: New Orleans and on Chicago P.D., but as a different character.
Chicago Fire airs on Tuesdays at 10/9c on NBC.
