1. He knew to an extent what the plan for Sam was, yes.

2. We like to leave that to the viewers to think about. I'd like to think that they are in Heaven, but perhaps not.

3. I think that being down there for hundreds of years has turned her into a demon. There aren't any plans for her to come back as of now.

4. Again, can't help with that one.

5. Jane was the last Nephilim on earth.

6. Now that we've introduced the darkness, knights of hell are a tricky matter. I used to believe an archangel or anything above it could kill a knight, but now that we know what brought them about, I'm not quite so sure.

7. Angels, demons, and humans are the only beings confirmed. I'm willing to bet it can kill other species, but not to the extent you were saying.

8. No, I don't believe so.

9. I think it depends on how strong the magic was. I think that if the sorcerer was strong enough, and used powerful enough magic, the coin would be able to kill Lilith, and maybe angels too.

10. No, he would not have.
