Since Chicago PD premiered, the show and the One Chicago franchise as a whole has introduced a very long list of dramatic storylines and characters. On top of that, viewers also have to regularly deal with the disappointing fact that many of the series' former stars have left, including Toya Turner, who left the series not long ago. As a result, there is no denying that One Chicago fans don't watch Chicago PD in hopes of getting to regularly laugh or smile.
However, One Chicago fans can sometimes be given a treat related to the franchise that will make them happy. For example, it was pretty hilarious for fans to learn that Taylor Kinney starred in an elaborate fake Christmas movie called The Gift EXchange. Another recent heartwarming story that involved the cast of Chicago PD came when a behind-the-scenes video was released that revealed something fans should love.
Chicago PD fans were disappointed to learn that Patrick John Flueger was taking a leave of absence from the show before he returned to set so he could resume filming. With Flueger stepping away from the drama series for that time, some fans may have wondered how that would have affected his co-stars. Based on one recently released video, it seems very likely that his co-stars were disappointed to see him depart, even if it was only for a little while.
In December 2025, Flueger posted a video on his Instagram account that showed footage of the team that makes Chicago PD happen from behind the scenes of the series. The clip showed Flueger being sung to by the cast and crew of Chicago PD, who were celebrating the actor's birthday. On December 10, 2025, Flueger turned 42 years old as Famous Birthday states he was born on December 10, 1983, in Red Wing, Minnesota.
As any Chicago PD fans will already know, the show depicts its cast running into a slew of scary scenes and dealing with highly emotional scenarios. Still, it seems obvious that the show's cast could still have a lot of fun on set, since the drama their characters go through could be kept at arm's reach. Even while knowing that fact, seeing the show's cast and crew serenading one of their own while sporting huge smiles is likely to make viewers feel warm and tingly inside.
Chicago PD returns January 7 at 10/9c on NBC.
