First why would the angels Cass or Zeke not know the language, ok maybe we can believe that Metatron wrote it in a way that angels would not know but why would a demon from the 15th century know more than angels... Just no
I like Cass but i am sick of him a bit, his eps seem the most forced storywise, that pointless repear sleeping with him and this woman who is the weirdest woman on earth, gives control of her baby to a random man and says you are special for no reason, so uncomfortably forced.
I didn't really like the Crowley thing but its interesting
Motw was actually pretty good but i am not liking the forced dumb plot of the ep
