It's basically canon that Dean could never kill Sam, but as much as I love Kripke, and as much as I admire/respect/have faith in him I still worry from time to time that he's going to do something JUST LIKE THAT just to mess with us (and well, to surprise us, shock us, whatever). Because like you said, he likes to see us squirm, and I know no matter what the series is going out with a big bang, so I hope he just keeps in mind everything that's went on between the brothers so far and stays true to that. Once again, this isn't me knocking on Kripke - I love the guy, but I HAVE seen shows I adored jump the shark before and it would devastate me if that happened to Supernatural. And Dean killing Sam? Would totally be jumping the shark. (Okay, the series would be over by then so I'm not sure you could call it 'jumping the shark', but you get the point.)

I'm probably just more freaked out than I should be because there is next to no possible chance this show is ending pretty. It might be epic, but whatever happens we fangirls are going to be sobbing our eyes out and most likely grieving for weeks or months to come. XD

Driving off into the sunset is nice, but this being SPN that probably isn't going to happen, and it would sort of defeat the purpose of what Kripke's been trying to do all along anyway. I mentioned it somewhere else on this post, but I could actually see - if not a Thelma & Louise style ending - I could see Sam getting killed by some outside source and then Dean doing something incredibly heroic and getting himself killed in the process. Because, you know, there's no way Dean would want to live in a world without Sam.

(SORRY ABOUT THE RANTING! My internet has been a bitch so this is my first time checking up on my secrets and such. Heh.)
