The burning questions as ‘Chicago Fire,’ ‘P.D.’ and ‘Med’ begin new seasons

As “Chicago Fire, “Chicago P.D.,” and “Chicago Med,” return for their season premieres Wednesday, the “One Chicago” shows have season finale cliffhangers and cast changes to address.

Season 10 of “Fire,” season 9 of “P.D.” and season 7 of “Med” begin with personnel changes at Firehouse 51, love lives solidifying for some of the firefighters, a police sergeant backsliding into familiar habits, a doctor facing career-altering consequences, and the exits of two main characters.

Longtime fans, who are nicknamed “Chi-hards,” have a few questions of the trio of series:

• How will “One Chicago” continue to adhere to the complaints of “copaganda” — portrayals of police who can do no wrong — amid social unrest and reform?
• Will the shows have a backup plan regarding the delta variant after COVID-19 abruptly shut down filming last year?
• How will the shows plan to stay relevant after being on the air for several seasons?
