1. Why did the mark corrupt the bearer? If because of The Darkness, how? It was locked up.

2. Where was The Darkness locked up?

3. Could Cain overpower a leviathan? People are actually arguing it. Everybody knows I'm not exactly "The biggest fan" of the leviathans. But that's ridiculous.

4. Is Castiel really back at full power?
