I think I might possibly squee on this later.
I have to say I enjoyed this ep of SPN. Mary was pretty badass and so was John. The boys have some seriously kickass parents, now I know why they're so awesome! This vessel and the bloodlines thing is interesting. I think this still leaves the possibility that the boys are possibly interchangeable as vessels since it's all in their blood. But I guess it also leaves the possibility that they can be swapped out like in last week's ep, they'd probably still be suitable vessels, just not as awesome? Too bad they all never got to be a real family together. Poor Winchesters. And is it just me? Or is it looking more and more like the only real option is to kill Sam. Anna's plan seems like the only one that could have worked.
