Because anything could happen during season 3, it is difficult to predict exactly what will happen in season 4. If Flower isn’t found before season’s end, it could carry over into season 4.
Likewise, the show has yet to reveal who really got taken away instead of Flower. However, Ghosts season 3 has teased a few twists which could completely change the future of season 4 and beyond. Regardless of what happens in the overarching storylines, fans can expect to see more shenanigans around the mansion.
The relationship between Isaac and Nigel will likely continue to blossom with a few bumps along the way, and season 4 might even shed more light on peripheral ghosts like Stephanie and Crash. Sam and Jay will continue to get the BnB off the ground while facing the various problems that come along with living among a host of needy ghosts in a mansion that’s falling apart. Ghosts works so well because the story possibilities are limitless.
