Changes
Archie Kao's character Detective Sheldon Jin was killed in the first season's finale, thus his character will not be appearing in the second season of the show. However, showrunner Matt Olmstead revealed that "It [Jin's death] shakes everybody up...definitely for the next three or four episodes until people can re-galvanize as a family, but people have some hard feelings about how it all goes down."

Officer Kim Burgess would be joined by a new partner, whom Olmstead describes as being an important voice to the team in the second season and particularly for Burgess. Brian Geraghty was later announced to be portraying Sean Roman, the new partner of Kim Burgess (Marina Squerciati).

Jesse Lee Soffer revealed that there will be a lot more crossovers this season between Chicago P.D. and parent show Chicago Fire; "I think every episode from now on, they're going to have a couple characters from one show on the other" he told media sources.
