For starters, will Zoe exit or be recast? Zoe’s not in a position where she’s particularly crucial to the canvas right now, so writing her out seems like the natural choice. It’s possible B&B will try to find a replacement, but The Bold and the Beautiful perhaps has other more preferable options.
They could use that airtime for a new character or as an opportunity to let a character on the backburner take center stage again. Whatever the case, it feels like we could be building to a stopping point for Zoe’s story on The Bold and the Beautiful.
