Ah yes, so it all comes down to Sam being demon spawn. I figured from the beginning that would come up again. Meanwhile, freaky head thing much?
Dean realizes a little too late that soul selling might be, you know, bad. And Dean finally admits that Sam is his weak spot. It took them a bit too long to figure out that they keep going round and round on the whole martyr-go-round.
And the boys singing their hearts out off key. Gah, I love those boys.
They made me teary there when they were saying goodbye and Sam's screaming got to me too. Jared's turned into a fine actor compared to the first season where he was still finding his footing. There's a certain raw innocence to him just like Jensen has a definite world weariness.
And of course, Dean is left in hell screaming for Sam. Thanks Kripke. Thanks for that :/
Honestly I'm kinda shocked they went there. I mean short of Sam turning into a demon lord, Dean's pretty much screwed.
