1. If Sam tapped into his demonic abilities in s9, would he have been able to kill Abaddon?

2. Who was created first? Eve or Leviathans? (Not sure if this was asked already. If so, I'm sorry and ignore.) Who was stronger?

3. Could Castiel have fixed Sam more easily when he had the souls of Purgatory? That is, could he have restored the wall or would it have been out of his power, even with the power of the souls?

4. Why didn't Sam's soul turn into a demon from all the torture and mutilation brought on by Lucifer? (Sorry if this sounds like a dumb question). I ask since it's one of the ways to become a demon.

5. Were the Knights of Hell created by the power of the mark when Cain created the order? If so, why wasn't Lilith a knight when she was demonized by Lucifer, the original bearer of the mark?
