ZOMG! Where will Dean find the blood of a Slayer?!!!!!!!!
But seriously, folks...
You know, for all of the love I have for Bobby, dude, you're carrying a rifle and are supposedly the awesome-est of awesome hunters. You can't put one in the back of a moving target from a few hundred feet? Or Dean, pull a Mal and shoot the guy who just stabbed your entire universe in the back without blinking? For all I loved Dean's pawing of Sam and his very moving man!pain, the whole last scene was off for me in timing.
I don't think I can dig any deeper than that until next week. However, I do have a feeling Jo is going to give up to Ash in the back of his van. If the apocalypse were coming to my town, I wouldn't wanna die a virgin either.
