This is a better storyline than Hope going to work for Logan: Brook becoming co-CEO with Ridge, and Steffy having to deal with it
This is actually a much more interesting and satisfying and underhanded way for Hope to get back at Steffy. Going over to Logan is too easy. This way, it punishes Steffy right where hurts her most: her gigantic ego, and Steffy won't even connect that Hope was behind it! Wow, didn't know Hope had this kind of crafty manipulation in her...to stroke Brooke's ego to the point where Brooke did exactly what Hope wanted. Brooke is so full of herself she didn't even realize how she was being manipulated by her daughter. I'm sure that realization will come later
