Here is officially the last SPN spoiler I'm reading, a summary for the final episode:
THE APOCALYPSE – The entire season has been leading up to this showdown between good and evil. With the Apocalypse looming, Sam (Jared Padalecki) and Dean (Jensen Ackles) realize they are out of options and make heart-breaking decisions that will change their lives forever. A beloved character is killed.
Bobby or Castiel, we knew and loved thee well.
Anything more is too much detail. That much is as much as I'd guessed would have to happen, given the sadism level of Kripke.
Do you think it means that the boys will have to be complicit in the death of whoever it is?
Oh, god, don't kill Cas! Kill Bobby!
I feel shame, but those are my true up-against-the-wall colours.
Yeah, mine, too, I have to admit. I'm guessing the death will be on them in some way. Ouch.
I like Bobby, but I could easily see him sacrificing himself for the common good. Well, Cas, too, but Cas doesn't have a bullet he contemplates on a daily basis (that we know of).
More generic Supernatural spoiler stuff:
Just in case you were wondering, the season finale is the climax of the apocalypse storyline, despite the fact that there's a sixth season. And we'll see lots of Lucifer and Michael — but we'll also get to know Sam and Dean better, and see the things that shaped them into heroes.
Backstory! Yummy!

Apparently Allison Mack will no longer be a regular in the last season of Smallville: [link]
Both Misha Collins and Jim Beaver will be back. YES! Some spoilers here: [link]
There has been speculation of time passing as we head into S6, and some of the spoilers seem to indicate that as well. I wonder if Sam's appearance under the street lamp (after we see Dean tossing a roll to Ben through the window) is set at that future time.
