Supernatural Seaon 7 Finale

Wow....just wow....The leviathans are finally finished for, but wasn't expecting an ending like that, and a cliffhanger too T.T poor bobby was finally put to rest in the final episode. Looks like dean and cass were either killed along with the head leviathan or teleported because their both in purgatory now, so most likely they both died when the head leviathan exploded, not exactly sure but it looked like crowley knew what was going to happen. Though I don't like how cass just abandons dean in the very end while he's being sorrounded by all the monsters in purgatory. What a way to end the final episode
of season 7, definately looking forward to season 8 of Supernatural.
