I would have to believe it involves Caroline’s condition perhaps worsening swiftly, and Bo is going to go off with her to some sort of treatment facility. Other than that, it doesn’t make sense for Bo to simply up and leave his family for any other reason. I’m pretty sure they would not dare kill Bo off, and a replacement for him is simply out of the question. For once the writers have left us guessing the exit storyline involving a soap legend like Peter Reckell and what exactly that story line will be. Good work DAYS! Usually, at some point the exit story is spoiled or at least as obvious as the nose on your face. If Caroline goes away for treatment and progresses to the point where she returns to Salem, but Bo doesn’t has me wondering more about the why, where, when, how, etc., especially where Hope and Ciara are concerned. By the way, I don’t believe Stefano will have anything to do with Bo’s exit story.
