Sparks fly when a "Chicago Fire" vet returns to 51 this week. Naturally, things are awkward now between he and his ex, especially since Violet has shown interest in newbie Vasquez, with whom she shares clear chemistry. Carver later confronts Vasquez at Molly's, saying the firefighter is not what Violet needs. Everything works out in the end because Carver's surprise visit only works to bring Vasquez and Violet closer together. Or were you hoping to see her rekindle things with Carver?
