We Can't Get Enough of These 10 Duos on 'Chicago P.D.'
NBC's Chicago P.D. follows the exploits of the fictitious 21st district of the titular department. When the team pairs off, which duos are the best?

As part of the One Chicago franchise, Chicago P.D. has been on the air for 12 seasons (and counting); and throughout these exhilariating seasons, several characters have been introduced. Some of them have been around from the beginning, others have left the show, and others have joined along the way to make an even stronger Intelligence Unit.
