No, not after they found GP. I think (and I really need to stress that this is speculation), I think SB might have had a good play at the outset. He might have told BL and parents to keep quiet bc they never expected GP to be found. They never expected.... the Bethunes. And, the play was keep your mouth shut bc when they cannot find her they are going to come to you before inclement weather sets in and they will plead you out for her location. This has always been my thought process on where he might have been going at the outset.
This backfired spectacularly, however, because they found GP. And, BL was gone before they even found her. So, if this was SB's plan, BL could have ignored it and decided to either go on the run or end it. I don't think SB ever would have counseled him to run. This much I give him credit for. That and keeping Cassie out of it. If Cassie doesn't know anything Cassie has no exposure. That, and privilege between the parents and SB is not breached. MOO
