Cruz goes undercover

Voight was convinced that the fire was connected to an ongoing string of robberies through the city, and that a firefighter must have been passing their company’s lockbox key to the robbery crew. They even knew which company they suspected and they wanted Cruz to go undercover, which Grissom was quick to approve so he could preserve the department’s image.

Cruz put his apprehension aside to do the right thing, because he’s a good guy like that, and Matthew Casey (Jesse Spencer) sold the story that he was being sent to another house as punishment for leaving a piece of equipment behind. Severide didn’t take the true story well and neither did Cruz’s brother Leon (returning guest star Jeff Lima), given his own past history working for Voight—which was helpfully shown in the “previously on” at the start of this episode.

Leon reminded Cruz about his difficult experience going undercover, with Chicago Fire turning the tables so that he was the one trying to help his brother. Although he mostly succeeded in making Cruz more nervous the night before he walked into Engine Company 66. He quickly realized that the vibe, and the suspects…er, coworkers…were completely different from the group that he was used to working with, and they struggled without him too.

While Grissom and Boden argued over how long they’d let the undercover operation go on, Cruz made friends with one of the firefighters at 66, Suggs, who claimed he hadn’t been on shift the previous day because of a dental appointment. That made him prime suspect number one, because with Chicago Fire as in most TV shows, it’s normally the guy you think couldn’t ever have done it. There’s always got to be that twist ending, after all.
