Lieutenant Casey (Jesse Spencer) deals with the fallout of his sister Christie's (guest star Nicole Forester) impending divorce. Meanwhile, Dawson (Monica Raymund) and Mills (Charlie Barnett) settle into their new roles at Station 51. Elsewhere, Brett (Kara Kilmer) can't decide if she wants to leave Chicago and the Molly's crew still can't figure out how to get the food truck started.
Casey learns that his sister and niece are going through a hard time because her husband is broke. Casey goes to see him and he tells him that they're going through a divorce. Casey thinks he's hiding something. Cruz is upset that he can't drive the truck. So Boden tries to plead his case and when he doesn't get it, he's prepared to go up higher and is warned if he does, there'll be consequences. Brett is trying to decide whether to stay in Chicago or move to Indiana. And Severide is still drinking.—rcs0411@yahoo.com
