Fun fact: There was a Moloch in Buffy the Vampire Slayer, the first MotW series that set the style for shows like Supernatural or Charmed, though he was a little different as he possessed a robot and got electrocuted.

So, Sam and Dean call Arthur Ketch by his last name, unusual of Supernatural characters. My favorite part was where Dean (I think) says "I don't like him. He creeps me out". Of course now that he is officially against Sam and Dean now, and with only six episodes left, it's only a matter of time before the writers put Ketch to the use I'm sure he was designed for - torturing Sam and Dean.

And, Game of Thrones reference, with Sam and Dean's cover ID's being Stark and Martell
