Looking Out for Stateville

S3 E12: Voight (Jason Beghe) convinces Deputy Crowley (guest star Barbara Eve Harris) to bring in his former cellmate, Eddie Little (guest star Clancy Brown), as a CI for the unit in order to help bring down a big-time cocaine supplier and his local dealers. Antonio (Jon Seda) is skeptical of this decision but Voight puts him at ease when he opens up about his time in prison with Little. Meanwhile, Burgess (Marina Squerciati) makes a difficult decision regarding her relationship with Ruzek (Patrick Flueger), and Roman (Brian Geraghty) devises a plan to help fund Platt (Amy Morton) and Mouch's (guest star Christian Stolte) wedding with the help of Firehouse 51.
