You guys forget God resurrected Castiel back "new and improved" in "Swan Song". He probably had the power to enter and exit the Cage successfully, or at least he thought he did according to "The Man Who Would Be King".
Speaking of the Cage, I still don't understand how Castiel, flew straight down the other eight layers of Hell, into the Cage, past Lucifer and Michael, picked up Sam's physical body, and then dragged him hack up to Earth in a matter of hours. When it took a legion of angels months to break Dean from a much higher circle of Hell. It doesn't make sense.
chopping the head off and isolating it from the body is kind of time consuming, and they had like five leviathans on them at the same time, one of whom was presumably the most powerful.
I wonder where the other Pagan Gods are...that lady pagan god said in season 5 that there's billions of them...
We already have met Osiris this season and we will meet another in episode 12, Chronos.
I only recall the monsters from purgatory and the two witches.
Before season 5, did Sam and Dean meet Pagan Gods? Cause if so, why did they look SHOCKED to see Pagan Gods in the Motel episode?
Osiris was from episode 4, Dean's trial.
Those weren't gods and yes they have faced gods before back in season 1, a Norse god posed as the scarecrow
The reason they were shocked was not because of the gods but the overwhelming amount of gods in one place.
He was a demon.I don't know if they count as Pagan Gods, but there was also Samhain in season 4 and whatever that Scarecrow was back in S1.
Exclusive: Supernatural Resurrects Vampire Diaries' Sara Canning For a Hot Date with Dean!
Ex-Vampire Diaries star Sara Canning is about to become the latest notch on Dean Winchester’s belt.
TVLine has learned exclusively that Supernatural has tapped Canning to guest star as a lust interest for Jensen Ackles’ demon warrior.
She’ll play Lydia, a character executive producer Sera Gamble describes as “wry, independent, and as fun-loving as Dean.” Gamble adds that she and Dean “have a memorable evening that takes an unexpected turn.”
The original casting breakdown for Lydia took things a step further, describing their encounter as a “sizzling one-night stand.”
Canning, who played Elena and Jeremy’s beloved Aunt Jenna on Diaries until she was killed off in last May’s bloodbath, will appear in Supernatural‘s 13th episode (slated to air in late January).
Supernatural‘s fall finale airs Friday at 9/8c on The CW.

He was a demon.
Lopping off a few heads and leaving the Levis to regenerate would still buy more time. Ultimately not a big deal, it was just the usual Supernatural plot hole of the week. These little things come up a lot. This one in particular just kind of annoyed me.
