Lance Baker

After he's injured in a terrible fire at an auto machine shop, Jose Vargas is forced to go on disability and leave his life as a firefighter behind - a task he finds incredibly difficult. Chief Boden tries to help a suspected teenage firebug. Also, Severide receives an enticing invitation from Renee, a woman who he saved from a car crash incident involving live electrical wires. Meanwhile, Cruz tries to save his younger brother Leon from the gang he is involved with.

Antonio (Jon Seda) and his sister Gabriela (guest star Monica Raymund) go to the office of Elliot Gish (guest star Robert Knepper), the man they believe started the fire that killed Shay. Intelligence along with patrol officers Burgess (Marina Squerciati) and Roman (Brian Geraghty) put pressure on Gish to try and make him confess. Lindsay (Sophia Bush) approaches Voight (Jason Beghe) about returning to Intelligence when she realizes that the task force isn’t what she thought it would be. At the same time Desk Sgt. Platt (Amy Morton) is acting strange and has everyone curious as to why she’s being overly cheery, friendly and nice.
