I don't know, but hope it all comes out with the right type of counseling and trust. I noticed how nervous JP got that they were even getting a counselor.
Of course he doesn't. JP is scared you know what about what his sons are going to be revealing. I hope and pray that they can get the boys to trust the counselor and provide enough damning evidence to make sure JP never again gets custody of his sons.
I don't have much faith that Susan will ever be found or that Josh will face justice for the more than likely murder of Susan. But at the very least I hope that Josh is never allowed to get his meat hooks into his sons and continue the horrendous cycle within the Powell family.
