Cast members David Eigenberg and Jessy Schram raise doubts about a potential One Chicago crossover this upcoming season. Despite a slight delay, NBC eventually renewed Chicago Fire season 13, Chicago PD season 12, and Chicago Med season 10, preserving the network’s One Chicago Wednesday block. As all three shows return to their usual programming schedule with a total of 22 episodes, One Chicago can tackle so many more storylines in its new year. This also effectively renews hopes for a new crossover event, which the Wolf Entertainment and NBC franchise is known for.
