Yes, that does seem likely. Nearly infinite time to research humanity and he knows so little about how we work? That sounds like interference of some sort.

I compared it to the state of one of my friends back home and he agreed. Cole's not an angel by any means but he's another incorporeal being with memory problems. I almost wish he were here so I could ask him about it but if he were here he'd be in the same boat as the rest of us and I'd hate to have to kill him too. Or be killed by him, I suppose.

[Dorian's delivery is a little too even for that to be a joke.]

I would ask Castiel about it but Jimmy said I'm direct and I scare him. That doesn't seem likely to help him out at the moment.
