In a recent interview with Variety, “Chicago Fire” co-creator Derek Haas admitted that he wasn’t willing to disappoint anyone by letting Brett and Casey’s relationship die simply because Jesse Spencer is no longer on the show. Not only will Casey and Brett maintain a long-distance connection, but Haas is leaving the door wide open for future guest appearances if Spencer’s interested. “It would have felt like cheating after having them building that relationship over so many seasons and then just throwing it away because of production demand,” he told Variety. He also noted, “I would be mortified if there was a wedding that didn’t include Casey,” alluding to the upcoming nuptials of Stella (Miranda Rae Mayo) and Severide (Taylor Kinney).
Fans are understandably excited. @MeetUsAtMollys, the Twitter account of the official “One Chicago” podcast, tweeted out their support for the long-distance couple in November 2021, saying, “Casey and Brett being pen pals? That’s adorable! #ChicagoFire.” Fans were mostly supportive in the comment section, including @IamLindaL, who wrote, “Even without Casey on-screen, Brettsey still continues to be the cutest couple! #Brettsey,” and @samantharob23 adding, “I just love them so much! I’m glad we’re still getting Brettsey content even if Casey went and moved to Oregon.”
