The episode revealed the bond between Brett and Casey is stronger than ever as Casey continues to support Brett, and Brett clearly appreciates what he’s doing for her.
So does their increasingly close bond as demonstrated in “Off The Grid” means those sparks flying between them will be fanned into a flame for fans of the relationship?
Chicago Fire spent most of “Off The Grid” on the Sean Roman storyline connecting Fire to P.D. for the two-part crossover, but the side plot was all about Brett trying to connect with her birth mother with Casey along for the ride.
