I just watched the second episode. That husband is a piece of shit. Who cares if the teenage son was a handful. He still lost his mother and then on top of that his piece of shit step-father refuses to let him get anything of his, anything of his mom's and flat out says that Pistol will never get any of her ashes. That really pisses me off.
I hope that there is some kindhearted lawyer out there that sees this and can help Pistol. Not sure what they can do, but that guy needs some kind of justice even if it is just getting something of his mother's to keep.
