By "how the supernatural operates", I meant how supernatural beings live, what are their capabilities, what do they usually do?"

As for Cass being human vs Crowley being human, the reason why I like the latter and the former not so much is because we have had so much glimpses of Cass being depowered, losing his memory and living as a human, whereas it was the first time they introduced the concept to Crowley. And note that I said it was happening alongside Abaddon's build-up. As a Big Bad, Crowley offers nothing new to the table and we needed some new female characters around. Thus, I was happy with the direction they seemed to be going for but that just went to waste.
