Titled "I Held Her Hand," next week's episode will see two members of the squad in a heated argument because of their opposing views. According to the official synopsis for episode 5, Lt.

According to Entertainment Weekly's Spoiler Room segment, Boden will get a blast from the past when Jimmy, his stepson from his second marriage, comes to Chicago to visit him. Executive producer Michael Brandt teased that Jimmy visits the Windy City to share some special news to his stepfather.
