One of the biggest surprises of the year came when Patrick John Flueger, who plays Adam Ruzek on Chicago P.D., was absent from the major 2026 crossover event.
His absence didn’t go unnoticed. Fans quickly took to social media, questioning why such a key character was missing from one of the franchise’s most important episodes.
The reason? Flueger had taken a personal leave of absence, which was later written into the show as Ruzek stepping away from work to care for his father. This real-life situation added emotional depth to the storyline, even in his absence.
Fortunately, the news wasn’t all negative. Reports confirmed that Flueger had already returned to filming and is expected to reappear in upcoming episodes. His comeback is highly anticipated, especially given his long-standing role in the series.
Interestingly, his absence also allowed other characters to step into the spotlight, giving the cast a chance to explore new dynamics and relationships. While fans missed him, the show used the opportunity to expand its storytelling.
At the same time, the crossover compensated by bringing back other familiar faces, ensuring that the event still felt big and impactful.
Flueger’s situation highlights the challenges of managing a large ensemble cast, especially when real-life circumstances come into play. It also shows how the franchise adapts, balancing actor availability with storytelling needs.
For fans, the takeaway is clear: even when key cast members step away, One Chicago finds a way to keep the drama alive—and often comes back even stronger.
