Once Upon A Time, there were three brothers, who looked perhaps slightly more pig-like than most. And when two of them died, they even made an oinky noise. Into this situation entered another set of brothers, two this time. One is fated to die and the other is dead-no-longer and guilty… and possibly evil. These two brothers travel to find the leftovers of the pig brothers and find heavy foreshadowing, while Hansel and Gretel find the house of the evil witch far in the deep dark woods.
The diagnosis? Fairy tales, read to a comatose girl poisoned by her stepmother. Sam convinces her father, a friendly and helpful doctor, to “let her go” while Dean saves Little Red Riding hood from the wolf. Successful, they give us ominous foreshadowing when the doctor says, “it’s really over” with fifteen minutes left. Also Sam swallows a lot and then leaves Dean sleeping in a motel bed.
Sam’s after the crossroads demon and this is where the episode gets interesting (despite good promos, the fairytale plot was fairly thin). He’s here to get Dean’s soul back at the barrel of the colt. She notes that it’s not the original gun, giving us a little background on Sam’s demon friend. However, she can’t help Sam. She’s merely a saleswoman. For that, Sam kills her anyhow. This shows two things- that Sam is becoming increasingly dark, but also that he will be forced to listen to his demon friend if he wants to save Dean and any chance of his humanity. Certainly, the only one who can save Sam from himself is Dean. Meanwhile there are increasingly fewer options for keeping Dean out of hell. However, I think this is super clear to all fans.
I’m getting tired of the writers beating simple things into our heads instead of giving us a little more dimension. The old adage of “show us, don’t tell us” obviously hasn’t been heard by the writing crew. They’re just lucky that it all comes out visually attractive and with good one-liners, even if it’s sometimes plot-stupid.
