Chad Rook returns to Supernatural: What were his previous roles?

Too bad they couldn’t get Kurt Fuller. Why are the angels different but Bobby and Kevin are the same. Or at least look the same.

And while I’m at it - who else thought that the idea of demons and angels going to the Empty when they die is lame? Eternal rest for an Demon. A demon. Much less an angel. I’d prefer to think that their energies just went back to the universe...
