To all of those who aren't big fans of Cassie and Hallie on Chicago Fire, some spoilers have come up that may give you another excuse to hate the tandem. I learned that the return of Hallie will bring intricate effects on the firefighter's life.
Read on for the latest scoop:
The return of Casey’s ex “complicates things a lot” for the firefighter, says executive producer Danielle Gelber. “Hallie has come back with renewed vigor, and is also passionate about something new in her life – not a person, but a pursuit… There’s really a feeling that she took a step away to get some distance, perspective, and she’s back with not a vengeance, but with renewed passion.”
