On the official subreddit for “Chicago P.D.” fans, user PAACDA2 started a thread titled “Who do you think will take the unit over of Voight was ever to retire or worse, die or not be able to work?” in which they explore a couple of answers to the question they posted. In short, they think that, while Detective Jay Halstead (Jesse Lee Soffer) may be Voight’s top choice, he might not do as good of a job as his predecessor in this hypothetical leadership role. Instead, they find Adam Ruzek (Patrick John Flueger) more suited to the job.
User Person_Somewhere_Aus, meanwhile, suggested that “Chicago P.D.” can’t continue without Voight before proposing a few-episodes-long trial run in which Jay temporarily becomes leader. User InfamousClock7287 agreed that Voight is irreplaceable, but suggested instead that a new actor might be brought on in lieu of an internal promotion.
Currently, Beghe seems committed to his “Chicago P.D.” role, making such speculation purely hypothetical for the time being. In fact, as recently as December 2021, producer Gwen Sigan told TVLine that a major plot development “will spark some attempts at change” for Voight as the series continues with him as its central team’s leader.
