Season 4 Episode 7
The Boden and Patterson feud spills over into 51; Boden investigates the source of the conspiracy. Treat Williams guest stars.
Captain Patterson (Brian White) suspends Severide (Taylor Kinney) from 51 for a day, citing their recent confrontation in the bar. Severide's dad, Benny (guest star Treat Williams), suggests they go after Patterson with both barrels, even going so far as to dig up dirt on Patterson's past. When Severide demurs, Benny takes matters into his own hands - and finds evidence of criminal wrongdoing from Patterson's youth. After much debate, Severide decides to turn over the file of evidence to Patterson. Patterson wants to know what Severide wants... but Severide insists he wants nothing - just the chance to remind Patterson that they're both human and can do the right thing when it's called for.
Meanwhile, the conspiracy case against Boden (Eamonn Walker) takes a turn for the worse. In addition to the faked photos that show his accuser beaten and bruised, Boden's fingerprints were on the victim's wine bottle - which seemingly backs up the woman's story. Boden unintentionally makes matters worse when he looks into the apartment building's security camera. With his suspicions firmly pointed in one direction - at Chief Riddle - he confronts Riddle at a C.F.D. gala, insisting that he'll uncover the truth. In a show of solidarity, all of 51 unites behind Boden at the event.
