Jennifer Maas TV Business WriterSPOLER ALERT: Do not read if you have not watched “Farnsby & B,” the Season 2 finale of “Ghosts.”Sam (Rose McIver) and Jay (Utkarsh Ambudkar) finally opened their bed & breakfast in the “Ghosts” Season 1 finale Thursday — only for their dreams to come literally crashing down moments later thanks to a curse. In the closing seconds of the episode, titled “Farnsby & B,” Sam and Jay are ready to welcome their first guests to the Woodstone B&B after defeating their enemy neighbors the Farnsbys in a game of pickle ball to get them to close their spitefully opened competitor, the Farsnby & B.But just as they open the doors, the floorboards crumble beneath them, suggesting the curse Thor (Devan Chandler Long) put on them before he got to know Sam is actually real.
