I didn’t really watch this one very carefully. I think the gist of it was: the writing staff of Supernatural run with Mayan mythology and don’t care how closely they get to it. 😉
Also, Sam wants to eat organic apples while Dean wants Sam to be his brother and to hunt monsters with him forever and ever.
And one woman was the baddie, the other an accomplice of sorts for decades.
At least there were no flashbacks … oh, shoot. Spoke too soon. They got one in. And I am highly suspect of Sam’s year off. It’s too Kodachrome, giving us those nice bright colors, those greens of summers, make us think all the world’s a sunny day.
