Bela should become a series regular in the second half of Ghosts season 4, as she is the only other living character who knows about the ghosts and understands Sam’s link to them. Thanks to her rebellious nature, there is more room for Bela to have fun storylines with the ghosts than there is with Sam and Jay.
After three years, Sam and Jay have gotten good at simply appeasing the ghosts, and often take a backseat as their backstories and internal power struggles command the show’s primary focus. While this isn’t necessarily a problem, it is a welcome change for Ghosts season 4 to feature a more proactive human character in Bela.
Some of these characters, like Sam’s estranged father Frank, or Jay’s parents, only appear in one or two outings. However, others gradually became Ghosts season 4 supporting stars. Patience’s arc lasted three episodes and ended in a way that left the door open for her potential return in future episodes, while the role of Sam and Jay’s construction worker and business partner Mark has grown as Jay’s ambitious plans for an onsite restaurant came to the fore. There is one guest star in particular who is overdue a promotion to series regular status.
