A shaky, worried Hallie meets Dawson for a cup of coffee downtown. As her eyes fill with tears, Hallie asks Dawson to convince Matt not to testify against Detective Voight's son, since she knows they're close and he'd listen to her. Hallie's tried to tell him herself, but to no avail. She can sense danger ahead, and she cares more for Matt's safety than Matt's righteousness. Elsewhere in Chicago, the guys are gathered around an industrial building, with Severide riding in the snorkel basket trying to help a graffiti artist named Zito get down from his ladder. An unmarked cop car pulls up and out comes Voight, a menacing partner in tow. As Severide and the men hold Casey back, Voight asks Casey if his fiancee will be at the deposition with him tomorrow. At the mention of Hallie, Casey loses it and goes after Voight, but the guys hold him back. Tensions escalate as the crew heads back to the trucks, Voight looking after them with a signature glint in his eye.
