The One Chicago universe continued this week with Chicago Med, Chicago Fire and Chicago PD episodes that started pointing the new season in its own directions.
With the previous season’s cliffhangers resolved in last week’s premieres, this Wednesday’s installments set up plot points and character developments that will pave the way forward. And of course, there was no shortage of fresh drama. Chicago Med had power struggles in the Emergency Department between several doctors while fans saw Chicago PD‘s Kim Burgess return to duty and Chicago Fire featured one character becoming a celebrity—if only for a lot less than 15 minutes.
These are the things you should know from this week in One Chicago, and the things we want to know as we wait for the next new episodes.
SPOILER ALERT: This article contains spoilers for the season premieres of Chicago Med, Chicago Fire and Chicago PD.

Chicago Med: How much has Marcel changed?
Dr. Crockett Marcel (Dominic Rains) didn’t have a lot of screen time in this Chicago Med season 7 episode, but it was enough to show that he’s not the same doctor who walked into the ED at the start of season 5. That, in turn, could have huge implications for his character.
In “To Lean In or to Let Go,” Marcel was approached by Sharon Goodwin (S. Epatha Merkerson) to sign up for her new resident mentoring program. Though he downplayed the idea, later in the episode he wound up giving solid advice to resident Vanessa Taylor (recurring guest star Asjha Cooper) and agreeing to become her advisor.
Marcel was incredibly cavalier when Chicago Med first introduced him. He was sleeping in ED beds and doling out questionable advice to med student Noah Sexton (former recurring guest star Roland Buck III). That Marcel shouldn’t have been influencing anybody. Two seasons later he’s being approached to advise med students and it seems like he’ll be working with Vanessa at least a little more, judging by the above photo from next week’s episode. Regardless of Maggie Lockwood’s (Marlyne Barrett) disapproval, he’s clearly matured. (And would she have been so keen to tell off Marcel if the situation had involved anyone other than her daughter?)
This is great for his character, because frankly the “cavalier doctor” has been done so many times on so many shows, and it’s compounded on Chicago Med where characters break the rules on a routine basis. Marcel became a lot more interesting to watch when audiences learned more about his trauma and saw his more serious side. Dominic Rains has been giving his everything to the part, so this turning over a new leaf gives Marcel a chance to maximize that potential and become the show’s breakout hero.
