I must confess: i wasn't expecting much from this episode; but, in the end, i actually found "Skin and Bones" to be a very good surprise. (SPOILERS from here on, you've been warned!)
So there's the Edlund family (mom Elena, dady Grady and kids Derrek and Tim) which has moved out of town into a farmhouse in the country, tagged by a relative (Grady's brother, Rawdy) and the resident indian, Eddie Bear (Great character indeed). One day Grady and his pals go hunting in the woods, where they get lost, and two of them ultimately end up dead due to the hostile environment and lack of survival skills(and other things)... Grady is the only one to make it back home, 10 days after, right when his family was beggining to question wheter they were still alive. But the returnee Grady is quite not himself, mind and body wise, and his new ill and dark self will cast some light over shady family secrets. There's nothing light about this episode, it's really dark and tormenting. There's no major twist, but the the actors are competent and consistent enough to make you feel the character's distress, and the horror scenes may be disturbing even if you're not looking right at it (unless you like the sight or sound of a dead person being chopped to pieces for dinner, which i hope you don't, unless you're the reincarnation of Jeff Dhamer). There were some moments i could see a glimpse of "Deliverance" (1972), not that it looks like the movie at all, but the characters kind of share the same anguish, and there's some background elements in common.
So far this is the second best episode, losing only to the superb "The Family Man".
