Blood will Flow

I'm really anxious about Jack. I want them to do something interesting and different with him. If he just becomes evil and the next big bad, and Dean just spends his time rubbing it in Sam's face I'm gonna be pissed - I'm hoping they won't do that, because he's an interesting, and quite sweet, character. I've been watching bits online (since it hasn't fucking started in Australia) and every time Dean starts yelling I get seriously anxious, like I'm listening to my parents fight. I have no idea why, but this show sometimes stresses me the fuck out.

And yeah, Cas coming back. I dunno. Can they find anything new and interesting for him? Sometimes bringing him back feels too much like fan pandering.
