Last season, "Chicago Fire" was a surprise hit for NBC -- big enough to launch their own spinoff, "Chicago PD," which will premiere midseason 2014.
But for Casey (Jesse Spencer), Severide (Taylor Kinney) and the gang, things are still very hot at the fire station, with surprise pregnancies and shocking twists from last season's finale needing resolution.
Will Sarah Shahi's character Renee Royce be back? And what's going to happen with Severide and Shay (Lauren German)? Is it still too soon for Casey and Dawson (Monica Raymund) to hook up, especially now that she's seen what kind of shape his life is in? Watch our interview with Spencer and Kinney, above, for all the scoop.
Tell us: What do you want to see happen this season?
"Chicago Fire" Season 2 premieres Tues., Sept. 24 at 10 p.m. ET on NBC.
