Ok so, we've seen the boy's fight Azazel raiser of hell, no big deal, battle Lilith and Alistair in a fight to unleash the devil, beat the devil, and so on.
Then we have season 6, where we have Sam and Dean stand idly by while Castiel takes out Raphael all by himself, We Need No Winchester! then season 7, Purgatories doors slide right open and the Leviathans are loose. New big bads, supposed to be the first creations of god, sheeet these things mean business, but nah, last night we saw some Witches with marital issues wipe out a Leviathan without moving a muscle, or even be in the room! i mean f*** off, these leviathans are trash, i'd like to see a witch do that to an Angel, or Azazel even FFS! all i'm saying is that theres no reason to worry, these leviathans are no big deal, lets get a witch and throw them all down a bottomless hole.
Problem solved, thank you and good night!
