There’s been no shortage of harrowing Chicago PD episodes in the series’ dozen seasons to date, but former star Jesse Lee Soffer praises one above all the rest. There’s something to be said for a really strong villain. Plenty of Dick Wolf’s TV procedural shows have occasionally interrupted their typical case-of-the-week format to pit their casts against a more cunning or influential foe. Chicago PD season 12, for instance, introduces Deputy Chief Reid as a corrupt force attempting to blackmail Voight into complying with his schemes by holding information over his head about Torres sleeping with an informant.
