Chicago Fire 4×05 “Regarding This Wedding” – After a fire ruins a neighborhood wedding, Boden (Eamonn Walker) steps up to host the ceremony at the firehouse. That’s much to the chagrin of his boss, Chief Riddle (guest star Fredric Lehne), whose political aspirations have caused friction from within the firehouse. Meanwhile, Dawson (Monica Raymund), who returns to the house, also butts heads with Riddle over her ability to perform and is forced to defend herself despite Boden’s support. Severide (Taylor Kinney) finds himself fighting for his way back to his old position and Capt. Patterson (guest star Brian White) is caught between loyalty towards leadership and loyalty to his colleagues. Jesse Spencer, Kara Kilmer, Dora Madison, David Eigenberg, Yuri Sardarov, Joe Minoso and Christian Stolte also star. Nick Gehlfuss and Gordon Clapp also guest star.
