A Nuisance Call (S02E04)

Lieutenant Severide (Taylor Kinney) is anxious to implicate the serial arsonist, while Dawson (Monica Raymund) and Shay (Lauren German) get a shock on a routine call. Meanwhile, suspicions continue to point to Clarke (Jeff Hephner) as the mole inside the firehouse and Molly’s falls deeper into the red. Elsewhere, Mouch (Christian Stolte) campaigns for union president, with the aid of Isabella (Mena Suvari), and Boden (Eamonn Walker) butts heads with Gail McLeod (Michelle Forbes). (iTunes)
