Casey related scoop on the timeline for season 3 of Chicago P.D. and season 4 of Chicago Fire from TVLine's Matt Webb Mitovich

Here's some scoop on Chicago P.D. and Chicago Fire from this week's (Posted on 8/17/15) Matt's Inside Line column.

I read in an interview that since Chicago PD premieres first, they will resolve the storyline of Casey being kidnapped on that show, instead of Chicago Fire. Is that still the plan? –Chris
Nope. Even though P.D. premieres before Fire, the firefighter’s storyline will not be addressed on the spinoff. “We operate a little bit in a separate universe” when P.D. returns, executive producer Matt Olmstead tells TVLine, likening it to a “detached timeline.” “We were mindful to not have too many of the characters from Fire on P.D. because that’s a little weird if they’re at Molly’s having drinks. Then why aren’t they talking about where Casey is?”
