Lots added to the mythology this week. Men of Letters, Knights of Hell. Really enjoyed this week. However shouldnt Cass have made an appearance or Crowly. Surely the appearance of sucha powerful demon would have set off some signal in the supernatural world.
I wondered about that, too. I kept thinking they would try to call Cas, or that he would suddenly show up and take the little box. It certainly seems like something the Angels would want.
