I can tell that SP runs the show in the household...he is definitely the ring master. That must be really hard to be under his thumb, but Josh needs his support and is stuck. Explains the big bags and dark circles under Josh's eyes. He must be living with a stress scale ranking a 10 out of 10.
SP has his hand in the sock puppet, and JP knows it. He knows Daddy is "pleasuring himself" by making his outrageous statements, and knows that if Daddy will do that to a missing woman, he'll do it to his own son.
