Destination unknown...

What I thought I knew:

• There's a demon named Ruby who's played by a blonde actress...
• Sam may be the Antichrist

What's actually happened as of 3.05 "Bedtime Stories":

• There's a demon ("fallen angel" in her words) named Ruby who's played by a blonde actress named Katie Cassidy
• According to Ruby and the random demon in a body named Casey in 3.04 "Sin City", Sam was chosen by Azazel (Yellow Eyes) to be the second in command when he brought forth the demon army from the Devil's Gate. Ruby used the word Antichrist. Casey said Sam was supposed to lead the demons after Azazel was killed and that she had faith and would have followed him. So I'm going to say in this case that Sam was intended to be the Antichrist, and lost that position when Jake killed him. And maybe it remains to be seen what he is now.
  

So...that Antichrist thing is pretty awesome. And I'm already digging the idea of this war between Heaven and Hell with humans stuck in the middle.

I'm also pretty gung ho on this idea of Sam as something other than human. So far we know that Yellow Eyes was feeding baby Sam his blood and that Mary Winchester recognized Yellow Eyes the night he killed her. Also, Yellow Eyes systematically killed off all of Mary's friends and acquaintances after she died. What was going on with her and Yellow Eyes? Poor Dean and Sam. It seems like their parents were a seriously messed up pair. Those boys never stood a chance at normal.
