She didn't get much air time. Was she meant to be a short term character all around? Her strife with her father (deputy chief, "top man" of the CFD) not wanting her to be in harm's way with all that is something we can understand (even if misguided). In this case, they just wanted to show that some firefighters didn't really have much of a chance, be it bad luck, or just personal/relationship problems?

If that wasn't meant to be the case, was it some behind-the-scenes stuff, like she pissed off some cast members or higher ups on the show? Family/life emergency? She landed some other role?

EDIT: CFD (fire dept.), NOT 'B'
